Each enduro will be a timed event from the green flag (or waive off) to the checkered flag and the clock will not stop for any reason during this time. The length of the race shall be established in advance and shall conform to one of the following:

90 Minutes 1 Allowed Allowed

1) All required pit stops shall be for a minimum time of five (5) minutes. Required pit stops cannot be made within the first fifteen (15) minutes of the race and must be completed before the last five (5) minutes. Pit scrutineers will time pit stops, but the ultimate responsibility for the correct timing of the required time is that of the driver(s). Drivers who do not stay in the pits for the minimum five (5) minute stop will be Black Flagged and assessed a stop and go penalty with the stop time being equivalent to the time that the pit stop was short. Cars entering the pits for reasons other than a mandatory pit stops may drive safely around the check in point and the check out point. A crewmember or driver must notify the scrutineer when a pit stop is not to be considered a mandatory stop.

2) Cars entering the hot pits for the mandatory five (5) minute pit stop will drive directly to the designated Check In Point and timing of the pit stop will begin when the car passes the timing checkpoint. The car must be at or below the designated pit speed at the check in point. When pit procedures have been completed, and at the discretion of the driver, he/she will proceed to the Check Out Point where a pit scrutineer will note the time; elapsed time shall be from the time the car passes through Check In until the car passes through Check Out before entering the track.

3) A maximum of five (5) crewmembers, including the driver(s), will be allowed over the pit wall to work on the car at anytime. Pit crewmembers must be wearing crew or driver wristbands to be over the wall; wristbands will be issued at the enduro crew and driver meeting. Any deviation from this standard for crewmembers will result in a stop and go penalty of the car involved.

4) Minor repair work; tire changes, and driver changes are allowed during the pit stop. The car must run in the same configuration during the whole enduro; i.e., legal weight, equipment, etc. It is strongly recommended that the car be checked for excessive tire and brake wear, general safety, and leaks.

5) The use of generators, battery operated tools, or electricity in the pits is allowed. Generators must be 50 ft. from the pit wall. Nitrogen bottles taken to the pits must be secured and equipped with protection (e.g., metal cage) for the regulator.

6) For Enduros allowing refueling, fuel may be added to the car only by a driver or pit crewmember while wearing a fire retardant suit, gloves and a full-face helmet with visor down or balaclava with goggles. During refueling, the car motor must be off, the driver out of the car, and no other work may be performed on the vehicle during refueling. The start of refueling is defined as, when the cap is removed from either the car gas tank or the fuel container, whichever is first. One person, acting as fireman must be present in the pit, with full fire safety gear, equipped with a minimum 10 lb. fire extinguisher with the pin removed during refueling. Drivers will be responsible for providing the fire extinguisher. Only plastic containers may be used in refueling and no refueling towers will be used. Any deviation from this standard of refueling will result in the disqualification of the car involved.

7) Each pit area will be thoroughly cleaned and swept immediately after each pit stop. It is the responsibility of the entrant(s) to provide cleaning materials and equipment and to insure that the pit area is clean. Failure to do so will result in disqualification.

8) Drivers that have multiple cars or cars in different races may request the same pit area assignment for those respective races.

9) Starting grid position for an enduro held before the sprint races will be determined according to the fastest lap timed during the third practice session. If there are two drivers, either driver may start the race, however drivers may participate only in the car to which they are registered. If a car does not have a driver that participated in the session used for gridding, the car will be gridded in the back of the field and placed by class; a number draw will be used within classes. Starting grid position for an enduro held after the sprint races will be determined according to the fastest lap timed during the sprint races or, if time permits, by a separate qualifying session.

10) Speed limit in the pits is twenty five (25) mph. Anyone speeding in the pits will be black flagged after they have exited the pits and shall be assessed a stop, talk to the National Scrutineer and go penalty.

11) Pits will normally be open during the event including under full course yellow flag conditions, however at venues where pit space is very limited, the National Steward may declare the pits to be closed (at least for mandatory stops) during full course yellow flag conditions. This shall be announced at the Enduro Driver's Meeting.

12) Drivers who ignore a Yellow Flag shall be assessed a stop, talk to the National Scrutineer and go penalty.

13) If a driver is assessed a stop and go penalty, the car number will be shown at the Black Flag station. The driver will pull into pit lane on that lap and go directly to the Black Flag impound area and not to his pit area. No work may be done to the car during the pit stop and drivers who ignore the Black Flag shall be assessed a one minute penalty for each Black Flag passed. Black Flag stops may not be used towards the five-minute mandatory time.

14) Mechanical black flag stops may be used as the mandatory five (5) minute stop provided that it is within the allowed pit stop window and is for the full five (5) minutes.

15) Drivers should remember that enduro races are much longer than normally experienced and that they should pace themselves. Drink plenty of liquids, take care of yourself and your equipment and if you find you are making mistakes while driving, pull into the pits. Remember, this is for Fun.

16) The car may be push started by hand. The car must be running on its own power by pit checkout point. If the car is not running by the pit out mark, the crew can no longer push forward.
