Competition Criteria & Classes
Qualification for Power Drive® State Championship
In order to qualify for the Power Drive State Championship a team must first participate in one of the recognized preliminary events. See the Calendar section for a list of those events. The vehicle must pass the safety inspection and complete at least one lap of the endurance rally to be considered a participant. If a car is not able to qualify for competition at the state finals via the required preliminary event participation, that team may apply for a waiver to run in the exhibition class at the state finals. It will not be competing for points.
The following scoring criteria will be used for the Power Drive State Championship event. Scoring at preliminary and summer events will be at the discretion of event organizers. Some events may include only an endurance rally. Points accumulated at these events do not affect or carryover to the Championship event.
The entire documentation portion of the competition is worth a total of 300 possible points.
Each team will submit four progress reports on the project. These reports will describe the overall progress and accomplishments to date for each vehicle. They should be posted on the team's website. The team will supply a link to the website to Power Drive (Sharon Jefferson of OPPD, 444 So. 16th St. Mall, Omaha, NE 68102, or email@example.com). The first report is due at the end of January 2013 (reports posted prior to that date are encouraged, but will not be scored). The subsequent reports are due by the last days of February, March and April. Teams will receive 25 points for each month (January through April) in which they post an updated report.
Each vehicle (team) will also document the entire project. Particular attention is to be given to recording the vehicle's design and construction. This material is to be sent to Mr. Jeff Hanson of OPPD (444 So. 16th St. Mall, Omaha, NE 68102) and arrive no later than Saturday, April 21, 2013. The material may also be turned in at the first competition (to be determined). Retain a copy of the documentation for your own use during the inspection periods. The documentation should be kept up-to-date at all times and contain discussion notes, calculations, photos, drawings and test results. The documentation should include correspondence, news stories, information about fundraising efforts (donor names etc.), community support, school and general publicity, student, faculty, community involvement, and anything that would help describe the efforts involved in building the vehicle. Additional documentation in the form of video/audio tapes and CD's is required of the Advanced Class teams. Multi-media documentation of Standard Class teams will not be judged. Approved alternative media forms are: Audio Cassette Tape, VHS Video Tape, PowerPoint® and Video CD ROM disc. The multi-media documentation should be a marketing presentation aimed at potential sponsors, seeking donations of material, cash, or services. The presentation should be no longer than five (5) minutes.
Judging on the final report will be based on completeness of content, journalistic quality, effort and neatness. This portion of documentation is worth 200 possible points.
All vehicles will be tested on braking efficiency from cruising speed. From a running start (approximately 15 mph), the drivers will be signaled to stop the vehicle in as short a distance as possible. The vehicle must be kept under control and within certain boundaries during the stop. Uncontrolled stops will not count as legitimate attempts. Stopping distance and initial speed will be factored into the determination of braking efficiency. Each vehicle will be allowed two runs, with the average of the two being used to determine the score. Vehicles will be ranked and awarded points accordingly.
The brakes must be capable of holding the vehicle stationary when being pushed by one person.
The braking portion of the competition is worth 100 possible points.
A slalom course consisting of five (5) cones, spaced 25 feet apart will be run out and back, by each vehicle from a standing start. Points will be awarded based on the time to complete the course. Five (5) penalty seconds will be assessed for each cone struck. Ten (10) penalty seconds will be assessed for each cone knocked over. Five (5) penalty seconds will be assessed for each time a wheel leaves the ground. A rollover will require the vehicle to undergo a new qualification inspection and may result in disqualification from that day's competition. Teams are strongly encouraged to practice this maneuver prior to competition so that the vehicle's stability characteristics are known.
NOTE: Separate battery packs may be used for the Braking/Maneuverability competitions and the pre-race activities. The vehicle must be in the same body configuration (all body coverings in place) for braking and maneuverability as it is when starting the endurance competition.
The maneuverability portion of the competition is worth 100 possible points. The vehicle must be in the same body configuration (all body coverings in place) for braking and maneuverability as it is when starting the endurance competition.
Design and Construction Evaluation
Three independent judges will grade each vehicle on:
1. Quality and durability of construction
2. Engineering design principles utilized
3. Effective use of materials
4. Overall road worthiness of the vehicle
5. Creativity in design and construction
The design and construction evaluation is worth 100 possible points.
This portion of the competition is worth 600 possible points.
During this portion of the competition, vehicles will be required to run on a track for a period of one hour. At the end of one hour, the total number of completed laps will be counted. Only completed laps will be counted. The winner of this phase of the competition will be the vehicle that has completed the most laps.
Race officials will clear from the track any vehicles experiencing a breakdown or loss of power. That portion of the lap will not count toward the team's total. If the car returns to the track, it must do so from the pit area and will begin from the last complete lap total.
A vehicle that enters the pit area under its own power will be considered to have completed a lap. If the vehicle does not enter the pits under its own power, the last lap is not considered complete. At a point between 20 minutes and 40 minutes into the competition, a pit stop and driver change is mandatory. Teams that can only field one driver will sit in the pit for 45 seconds to simulate a driver change.
Except for the battery pack, no modifications may be made to the vehicle between inspection and competitions. Flat tires and other mechanical failures may be repaired, but only with like components. Gear ratios, steering ratios, and wheels/tires may not be changed between competition phases.
The endurance rally is worth 600 possible points.
Total competition points available - 1200
The overall winner will be the team (vehicle) that accumulates the most points from Documentation, Braking, Maneuverability, Design and Construction Evaluation, and Endurance. See the Awards section for other planned recognition.
Power Drive® has instituted a multi-class competition due to the number of participants and the variety of experience and skill levels involved. The defining criteria for these classes are listed below:
- Power Drive has instituted a new class in 2009. The Novice Class is identical to the Standard Class (see below) in all aspects except that to be entered in this class, a car cannot have won a trophy at any Power Drive sanctioned endurance rally.
- The Novice Class is an endurance rally classification only. These cars will compete along side the regular Standard Class cars in braking, maneuverability and design/engineering.
- A car that receives a trophy in the Novice Class at a preliminary event (i.e. Hastings, Lincoln, Columbus, etc.) will automatically be promoted to the Standard Class at the next event entered. The team will change the letter designation of the car from "N" to "S".

Rules & Regulations
The following rules and regulations govern the design, construction and operation of all Power Drive® vehicles. The rules were developed for the safety of the participants and must be followed by all participants.
Batteries must be lead acid only. Only batteries that will not leak if punctured, such as gel cell or AGM (Absorptive Glass Mat) will be allowed to participate. Battery number and voltage is not limited, but must meet specified weight limits, or must be the accepted battery types listed. Batteries must display all original manufacturers' labels. Batteries must be commercially retailed and available to any competitor. Custom built or specialized batteries are not allowed. Batteries must be stock and unmodified in any way, and meet all conditions of the manufacturer's written warranty.
Total battery weight can not exceed 67 pounds including any batteries used for motor controllers, contacts, relays, solenoids, instrumentation, computers, etc. Batteries used for two-way communications devices are not included in the total battery weight. Note: Many batteries advertised by the manufacturer as weighing 31 to 33 lbs. actually weigh in excess of 34 lbs. when prepared for use. It is suggested that arrangements be made in advance with your suppliers to return batteries that don't meet this requirement. Non-compliant batteries will not be allowed to compete for points.
Due to their construction and power ratings, the following batteries will be allowed, regardless of weight:
Optima SC25A, SC35A, Optima SC75/35 (side and top post) Optima 75u, 75/25
Odyssey Genesis G42 (VP, VPX, EP, EPX)
Exide Orbital Model 75/35
Champion Vortex 75/35
In addition, any commercial gel-cell or AGM battery with a manufacturer's rating of 45 amp-hr or less and a cold cranking (0 degrees F.) capacity of 720 CCA or less may be considered by rules officials. Any team wanting to use a battery pack in excess of 67 pounds that is not on the list above, must get it pre-approved by contacting Steve Anderson (402-403-8134 or firstname.lastname@example.org).
Batteries of vehicles are weighed at the beginning of each competition and whenever new batteries are introduced to a vehicle. In addition, batteries are subject to being weighed randomly - or at the discretion of track officials at any time at each rally.
Batteries mounted within the confines of the frame rails do not have to be mounted in a protective "box". The batteries must be securely fastened to the frame using bolts and/or clamps. Bungee cords are not sufficient. Drive batteries mounted outside of the frame rails must be enclosed in a rigid box or other structure that will protect them from puncture. The design of the battery box shall be non-conductive, or if made with conductive materials, shall assure that the battery terminals cannot contact the conductive material. All batteries must be securely attached to the vehicle in such a manner as to withstand an impact or roll-over. All battery terminals to be covered with rubber or plastic grommets to protect from accidental contact.
Drive batteries must be enclosed in a rigid box or other structure that will protect the batteries from puncture. The box must be securely fastened to the frame using bolts and/or clamps and the batteries must be held firmly in place within the box so they cannot move around within the box. The design of the battery box shall be non-conductive, or if made with conductive materials, shall assure that the battery terminals cannot contact the conductive material. Batteries must be securely attached to the vehicle in such a manner to withstand an impact or roll-over. Battery terminals to be covered with rubber or plastic grommets to protect from accidental contact.
Batteries may not be remotely recharged or replaced once the endurance competition has begun.
Batteries used for the braking and maneuverability portions of the competition do not need to comply with the weight restrictions of this section.
A Power Drive Advisory Committee member will be allowed to pre-certify competition batteries at the school prior to the competitions. If a team chooses to have this done, they should contact their committee advisor to arrange for this. If a battery, which has been pre-certified, is replaced during the season, it will have to be re-certified.
All vehicles must have fusing or a circuit breaker between the motor and battery. A master disconnect switch(es) or circuit breaker must be accessible by both the driver and by meet officials during the competition. The disconnect switch, or pull cord for the disconnect switch that is accessible to the meet officials, must be mounted on the outer part of the roll bar assembly near the driver’s shoulder level (or higher) and clearly marked with a red (or red outlined in white), equilateral triangle with four inch sides. The driver’s disconnect switch shall be mounted where he/she can operate it from the driving positions. The Driver’s switch can either be a separate device or the same as the device for the race officials. The driver will be asked to demonstrate its use during the vehicle inspection.
All electrically powered accessories must also be fused or protected by circuit breaker.
Motor power must be designed so that the motor(s) turn off automatically if the driver releases the throttle.
Wiring must be of suitable size so that the fuse or breaker will blow before the cable insulation can melt. Wiring should be neat, well insulated and securely tied to the frame. All wiring must be kept clear of moving parts and protected from chafing. The vehicle frame may not be used as a conductor for any part of the electrical system.
A maximum of one square meter of solar cells is allowed on Power Drive® vehicles entered in the Advanced Class competition. (The one square meter maximum refers to actual cell area and does not include area between the cells.) The cells must be safely attached to the body of the vehicle in such a manner that they do not protrude from the front, sides or rear, endangering others.
Wheels and Axles
Vehicles must have a minimum of three load-bearing wheels in contact with the ground at all times. Plastic BMX type wheels are not recommended, since they generally cannot withstand the side loads experienced in the maneuverability and endurance competitions.
The wheels and axles must be strong enough to withstand the test for braking, maneuvering, and endurance competitions.
Wheels must be covered if they could endanger the driver.
Axles must be a minimum diameter of 12mm or 1/2-inch unless supported at both ends. Safety wire or cotter pins must be used to secure cantilevered wheel axle nuts. Nylon lock nuts alone are not acceptable. A one-time variance will be allowed using double nuts for teams that forget this requirement. The nuts must be installed in the presence of an instructor and an inspector.
Vehicle ground clearance must exceed the sidewall height of the tire to keep the vehicle off the ground in the event of a flat tire.
Minimum standards apply to steering system components. Steering arms, rod ends, wire rope, ball joints, and all associated hardware serving to mount any steering elements must be equivalent - or greater - in strength than 1/4-inch diameter steel rod. Documentation for the vehicle must show the strength verification/calculation for steering components and team members should be able to describe the process used for that verification/calculation at vehicle inspections. Kingpins must be made of material that is as strong as or stronger than a 3/8-inch solid steel rod.
Vehicles must have a minimum turning radius of no more than 25 feet.
Fasteners used to connect ALL steering related components must be pinned or safety wired.(The same one-time variance for double nuts allowed.)
All vehicles must have mechanical or hydraulic brakes. Vehicles must have brakes on at least two wheels that are "on the same axle" (either both front or both rear wheels). Hand operated brakes must allow full application without taking the driver’s hands off the steering devices(s). Brakes that use an additional ground contacting mechanism are not allowed because of the possibility of adversely affecting the stability of the vehicle.
Effective braking will be checked before the endurance phase of the competition. A “push-test” will be conducted on all vehicles immediately before the start of each endurance competition.
Brakes must be able to stop the vehicle in a straight line without locking the wheels.
Regenerative braking is permitted in addition to conventional brakes on vehicles competing in the Advanced Class.
The brakes must be capable of holding the vehicle stationary while being pushed by one person.
All Power Drive® vehicles must be equipped with a clearly visible brake light that is activated automatically whenever the brakes are applied.
The brake light should be easily seen by a following vehicle and have a minimum visible area of 4 square inches.
All chains, gears, etc. must be guarded/covered to minimize exposure of personnel to “pinch-points” at the pulley/sprocket. The guard shall be designed such that no driver can reach out and get a hand or finger into the chain at any point. The guard/cover shall also serve as damage and injury protection for slipped or broken belts/chains. Fully enclosed body sections fulfill this requirement if there is a barrier between the driver and the chain. The vehicle must be rendered inoperable whenever the guard/cover is removed for access to the chain/belt.
Gear ratios may not be changed once the vehicle starts competition for the day. The same gear ratio must be used for all of the events. There will be no multi-speed transmissions on any competing Power Drive® vehicle.
Mirrors and Vision
All vehicles must have at least one functional rear view mirror (two recommended) - with a total mirror area of no less than eight square inches. The mirror(s) must provide a 120 degree field of vision to the rear (without manual adjustment). Field should extend 60 degrees on each side of centerline from the rear of the vehicle. Documentation should show testing and verification. Team members will be asked to demonstrate effectiveness or answer questions on testing.
The driver must have at least 270 degrees of unobstructed vision of the track, not including vision of the track seen through mirrors. Vision obstructed by frame members is an exception to this rule.
Each vehicle will be inspected before it is allowed to participate in the endurance phase of the Power Drive® competition. Each team should furnish a "Student Car Captain" to accompany the vehicle through the inspection process to answer questions about the vehicle and its construction.
All vehicles that have been subsequently modified must be presented for re-inspection prior to participating in any Power Drive® endurance rally.
Vehicles that do not conform to Power Drive® regulations or that have failed to pass all of the inspection phases of the competition will not be allowed to compete for points. Units that do not comply with the safety related regulations will not participate in the track events. A vehicle that has not been allowed to participate in preliminary events because it did not meet requirements, may obtain a waiver to participate in the State Championships IF the non-compliance has been corrected.
Drivers who cannot demonstrate compliance with Power Drive® regulations will not be allowed to participate. (Drivers must present and have on their person a valid driver's license at each competition.)
Inspections may be arranged prior to the day of the competition - if desired. This is advisable for first-time participants or if vehicle modifications are made between competitions so those unexpected items of noncompliance do not force the vehicle out of competition. These pre-competition inspections do not replace competition day inspections.
The purpose of the inspection phase of the competition is to judge the safety (construction, braking and stability) of the vehicle prior to the endurance phase of the competition. Modifications to a vehicle's components, such as changing gear ratios, installing different wheels, etc., could significantly alter a vehicle's performance characteristics and make it unsafe. For these reasons, changes to a vehicle's components between the inspection and endurance phases of a competition will not be allowed; however, components can be replaced with like components if necessary, e.g., breakdown, flat tire, etc.
The winner of the rally competition in each class will be subject to a post-event inspection, immediately following the heat.
All vehicles must have frame members and padding that protect the driver in the event of collisions from any direction. The minimum size of such frame members will be:
1-inch O.D. round, or 1-inch square tubing with:
0.0625-inch (16-gauge) wall thickness for mild-steel
0.058-inch wall thickness for 4130 chrome moly, and
0.083-inch wall thickness for aluminum
¾ inch (nominal) rigid conduit with:
.0625 wall thickness for steel
For extra support, used in triangulation, 3/4-inch O.D. round, or 3/4-inch square tubing may be used with:
0.0625-inch (16-gauge) wall thickness for mild-steel
0.058-inch wall thickness for 4130 chrome moly, and
0.083-inch wall thickness for aluminum
Frames constructed of other materials are allowed on Advanced Class vehicles providing it is demonstrated and documented that the alternative material(s) or methods provide equal or greater structural strength and protection/safety. It is important to remember that you need to document the calculations and/or testing of alternative frames.
Padding must be installed to prevent injury from contacting the frame members in the event of an accident. Padding must be at least 1/2-inch thick and made of closed-cell foam.
Driver must not be positioned with his/her head in front of torso, knees, and legs. This rule is designed to minimize injury in case of a crash.
Each vehicle shall have structural members at the front of the vehicle that act as a barrier, or bumper, to protect the feet of the driver and to help prevent intrusion into another vehicle in the event of contact. The minimum dimension of these structural members shall be eight (8) inches in the horizontal and eight (8) inches in the vertical dimensions. Blunt aerodynamic fairings may be used in front of the structural members to enhance airflow. The barrier must be made of materials that meet the minimum standards for frame components. This rule applies to vehicles with a single front steer wheel as well.
Frame members on the side of the vehicles shall be designed to help ensure that another vehicle cannot intrude into the driver's compartment in the event of contact. Therefore, the maximum open space between frame/reinforcing members must be less than 6 inches. That is, a 6-inch diameter sphere should not pass through any of the frame openings. Side impact protection must extend up to the highest level of the driver's shoulder. All of the driver's extremities must be contained within the roll cage during operation. Cars where the driver's arms or legs are not completely protected will not be allowed to compete. Monocoque frame cars must be constructed of materials sufficient to protect the driver in the event of a side impact. That determination will be made by the PowerDrive Advisory Committee (seek ruling before beginning construction). Cars that competed in the Standard Class in 2005/2006 will be allowed to retain their current configuration for one season.
The roll cage must extend high enough to provide a 2-inch space cushion above any body part of the largest driver. This is determined by drawing a straight line from the top of the roll cage to the next lowest support point on the vehicle frame that is capable of supporting the vehicle in the event of a rollover. The front wheels of the vehicle are not considered to be strong enough to be the next-lowest support point.
The center of the driver’s helmet must be positioned directly below the roll bar.
The roll cage must be cross-braced to the chassis, forward and rearward from a point that is no more than three inches vertically from the top of the roll cage. The forward bracing shall form a protective cage around the driver and be designed to protect the driver from side/front impact injury. Placing a straight edge across the front roll cage braces and running it down and forward, the edge must not touch the helmet, face-shield or other body part of the driver. The cage must be made of tubing that meets the minimum standards for frame/bracing components.
An inspection hole, at least 1/8-inch in diameter must be drilled in a non-critical area of the roll cage to permit inspector confirmation of the wall thickness.
Padding must be installed to prevent the driver's head or upper torso (waist up) from being injured when contacting the roll cage in the event of an accident. Padding must be at least 1/2-inch thick and made from closed-cell foam.
All parts of the driver shall be completely inside of the frame cage at all times when in the normal driving position.
Roll cages (Advanced class cars only) constructed of other materials may be allowed if it can be demonstrated that the alternative material(s) provide equal or greater structural strength and protection/safety.
Any questions regarding frame/roll cage compliance should be addressed by contacting the Advisory Committee (402) 552-4960 well before the first event.
All vehicles must demonstrate inherent stability at rest, while cornering, braking and cruising at top speed.
A head restraint, capable of withstanding a force of 100 pounds or greater in the rearward direction, is required to prevent whiplash. Padding must be installed to prevent the driver from being injured from contacting the head-restraint structural elements in the event of an accident.
All vehicles must be equipped, at a minimum, with a five-point safety harness similar to those used in racing stock cars and aerobatic aircraft. The harness/lap belt strapping is to be at least two inches in width and the harness set must be commercially available and installed in the vehicle in accordance with manufacturer’s instructions. Installation compliance must be included in the vehicle documentation. The harness shall be equipped with a quick release to allow easy exit from the vehicle.
The maximum overall length of a Power Drive® vehicle is 12 feet. The maximum overall width is forty-eight (48) inches.
All vehicles will be issued Power Drive® vehicle identification numbers, Power Drive Logo Decal, and a Clean Cities logo decal. All vehicle numbers will be one, two or three digit numbers. Once a number is issued, it will normally be retained in subsequent competitions. The numbers require an area approximately 6" wide by 8" high (for each digit). The Power Drive Decal is 15" wide by 8" high. The Clean Cities logo is 6.5 inches by 9 inches. The unit should have rigid or semi-rigid surfaces large enough to mount two vehicle numbers (one each side), and one each of the other two logos (front back or sides). It is highly recommended that the school name be displayed on each side of the car. Cars with visible names and numbers are easier for judges to notice during a heat, better facilitating accurate lap counting.
The body should not have sharp edges, nose cones, corners or other protrusions that could injure spectators or other drivers.
The vehicle must have a fixed floor pan that prevents the driver's feet from contacting the ground.
Race officials will have to push a car clear of the track in the event the car is disabled. It is recommended that a "push here" sign be added at the proper points on the vehicle. Damage to the body structure may occur during the competition if these markings are not present.
Enclosed canopies will not be taped-on or fastened in a manner that could hamper emergency egress. Driver must be capable of removing the canopy unassisted.
All drivers must wear DOT-approved motor vehicle/motorcycle helmets (full-face helmets are recommended) with a Snell rating of 95 or greater. The helmets must be clearly labeled as meeting the Snell rating. Bicycle helmets are not acceptable. Helmets must be worn with the chin straps correctly fastened. Drivers must wear heavy clothing, i.e., long-sleeve shirts, and long pants, enclosed shoes and gloves (made of leather or other protective material).
All drivers must wear eye protection (Z87 safety glasses with side shields or goggles). Face shields on helmets are sufficient.
All drivers must wear standard, commercially available footwear that protects the feet. The minimum standard is a good quality cross training or rough terrain hiking shoe.
All moving parts that could endanger the driver must be shielded.
Each team must have a dry chemical extinguisher present in the pit area. Minimum requirement is a ten-pound dry chemical extinguisher.
All safety equipment must be in place and fastened before the driver leaves the pit during the endurance competition. Teams are subject to one-lap penalties for each non-compliance.
All drivers must be at least 16 years old and hold a valid driver's license.
All drivers must sign a liability waiver prior to any competition. Drivers under 18 must have a parent or legal guardian co-sign the liability release.
For all phases of the competition, the vehicle operator is to weigh at least 180 pounds. Drivers weighing less than 180 pounds must carry enough ballast to make up that difference. All personal protective equipment, including helmet, clothing and glasses are considered part of the driver and count toward the 180 pound minimum.
Each team must furnish at least two qualified drivers for the endurance phase of each competition. If a second driver cannot be present for the endurance competition, one driver may participate, but a pit stop must be made as outlined above. The driver will remain stationary in the pit area for 45 seconds before being allowed to return to the track.
Drivers must be able to exit the vehicle, unassisted, in 20 seconds or less.
Driver and ballast will be weighed prior to each competition.
Ballast carried to offset driver weight must be securely fastened to the car and not carried on the driver's person, attached with bungee cord, or taped to the car. Ballast must be removable for weigh-in, but securely attached (belted, strapped or secured by fasteners) during competition. Only three types of ballast are acceptable:
A. Olympic-style weight discs (either padded or bare) fastened to the frame by bolts, straps or held in a container fastened to the frame.
B. Moldable bags of sand or shot. These must be sealed bags that can be fastened to the frame by straps or held in a container fastened to the frame. The bags must be labeled with the exact weight.
C. Metal bars with smooth edges. No more than four bars can be used at a time for the total ballast of one driver. Bars must be clearly marked with their individual weights and fastened to the frame by bolts, straps or held in a container fastened to the frame.
Each driver is responsible for providing the correct amount of ballast.
Ballast cannot be performance- or structure-related equipment, e.g., communication equipment, gauges, computers, wheel balance weights, etc. Certain non-performance items, such as cameras, music systems, etc., may be acceptable. Pre-approval of such ballast by a technical official is recommended.
There is a ($3,300 Standard Class - $3800 Advanced Class) limit on the value of the material used in the construction of the car. This includes the cost of the “starter kit” provided to new schools by the Power Drive Program (Value $900).
The dollar limitations are for the parts and materials used in the construction of the car, as it is presented for the competition. This specifically excludes:
Driver’s Clothing, Driver worn safety equipment, pit tools and spare parts, batteries used for maneuverability and braking.
It does include the batteries used for the endurance competition competition and all components of real time telemetry devices. If performance data is collected and later downloaded, the value of any collection hardware and software must be included in the car value.
Documentation is to include a detailed listing of purchases, donations and loans of all material used in the construction of the car. Itemization is to include the actual/estimated value and source of the material. Even if other documentation is not submitted, this item must accompany the vehicle in order to compete in the endurance competition.
Each rally will be governed by signal flags controlled by the Track Steward and Corner Workers. Each driver and pit crew member must be versed in the meaning and requirements of the signal flags.
Green- Signals the start of the competition. Once the competition has started it signals that the track is clear and full speed is authorized in this area.
Yellow- Caution. There is a problem in this area of the track. Slow down and prepare to stop if necessary. Fall into line behind the car ahead.
Absolutely no passing until clear of the caution zone.
Black- Warning/Penalty. If a furled (rolled up) black flag is pointed at the driver it is a warning of reckless or poor driving. Have the pit crew chief check with the track steward for clarification. A second offense or a serious violation of track rules will result in a black flag (unfurled). The driver must pit at the next opportunity and will be assessed a penalty at the discretion of the Track Steward. A black flag is also used to notify a driver to pit for various mechanical problems (flat tire, dragging part, missing safety glasses, inoperative brake light, etc.).
Red- Cease running. A track emergency is in progress. All cars come to a complete stop in place and await further instructions.
Checkered- Rally complete. Slow down and return to pit or staging area at next opportunity.
