During any sit-out period(s) and/or between heat races, an official shall collect all vehicles not currently racing and place in track lock box (impound).
As an enduro, laps and/or lap
counters shall not be corrected for vehicles jumping lanes.
Laps shall be recorded as shown.
Jumping / going threw lap counter on wrong
lane - Per the Trakmate system, minimum lap time will be
set meaning you WILL NOT GAIN
laps should a driver goes
through the counter on your lane. However, you
WILL LOOSE a lap should you go through
the counter on a someone else's lane.
