TECHNICAL BULLETIN 10-2-18

Regional Required Procedures--Effective Immediately


8 On-Track Procedures and Conduct


8.1 Regional Required Procedures


All regions will hold a Time Trial specific drivers meeting prior to the first on-track session of the event/weekend, where on-track procedures, regional nuances, and car class declarations will be discussed. All regions will hold at least one TT (or combined TT/HPDE4 if a mixed run group) download meeting each day after vehicles have been on track for a competition session.


Passengers are permitted at the discretion of the regional NASA Officials.


Cars will be pre-gridded based on their prior best lap times (“running grid”) except for the first session of the event, which will not count toward competition. The first session of subsequent days will count toward competition for that day. D/Q’s will be put into the T&S computer system at the end of each day. So, at times, drivers could be getting gridded based on lap times that will later be D/Q’d. Drivers should know their grid position before coming to pre-grid. All drivers should attempt to arrive at pre-gird 10 minutes prior to the scheduled session start time. The grid will be closed when the first TT car goes on track (may be closed earlier at the discretion of the region, with notification given in the TT drivers meeting). Once the grid is closed, cars arriving late will not be permitted to go on track without the specific approval of a TT Official.


The pole-sitter or pace car will take the cars out on track at 45 mph. This speed will be maintained until all cars are on track to provide the largest number of open hot laps to the group. Once all cars are on track, the pole-sitter or pace car will begin to pick up the pace (if a pace car is used, it will leave the track) so that vehicles can be at full speed through at least the final two turns prior to the start flag. Drivers should position their cars so there is about 1 second (7-10 car widths) behind the car in front of them at the green flag. During the “paced” lap and the first hot lap there is no passing permitted unless the passing driver is specifically given a point-by from the driver ahead.


Once a car enters the track, it is not permitted to enter the hot pits except to go to the black flag station or to exit the track. No work, adjustments, or tire checks may be done in the hot pits. Once a vehicle enters the hot pits, it must exit the track and go directly to Impound. The only exception is if a vehicle has entered the hot pits to go to the black flag station and the driver is instructed by a NASA Official to go back on track. All cars must report directly to Impound after exiting the track, regardless of how many laps were completed, unless there is a track exit sign directing only certain vehicles to impound. If a car has a mechanical failure, it must still report to Impound to avoid possible disqualification of that session’s lap times (even if it is on a flatbed).


Once a car is being held in impound, the driver may stay in the driver’s seat and wait for further instructions from TT/Tech Officials, or the driver may exit the vehicle and stand next to it, with the helmet and safety gear placed in the vehicle. The driver may not re-enter the vehicle until instructed to do so. The hood must remain closed, and nobody may test or work on the car; except, tire temps and pressures may be taken under the watch of TT/Tech officials. Tire pressures must not be adjusted until the vehicle is released from impound. Care must be taken when checking tire pressures so that air is not released. Any car that has been chosen by TT/Tech Officials to be Dyno tested that has been found to have had adjustments to tire pressures will have the tires inflated to 40 psi prior to the Dyno testing.


In order for a regional track record to be valid, the driver must get the car weighed and have the tires checked by Tech immediately after coming off track.


Disqualifications will be announced in the TT Download meeting(s), unless the TT Director contacts the driver(s) at another time to provide notification. A driver missing a required TT Download meeting where a DQ was announced shall be deemed “notified”.

Hi Greg,


Just so that I understand this part: "....except for the first session of the event, which will not count toward competition."


There is usually a "TT Warmup" session and then the first actual TT Session (Race). Does the wording quoted above refer to the first actual TT session (Race) or the warmup? In other words, does this rule say that the first actual Time Trials session does not count at all towards competition and is effectively then a qualifying session?


Thank you in advance for any clarification.
