If  it concerns teams where one of the drivers (or both) collected more than 150 IOC points use of power restrictors is obligatory.
(d) TWO CLASSES - On racing FIA GT cars GT1 cars and GT2 cars are raced apart. GT1 cars go to pros, GT2 cars to semi-pros and amateurs. On racing LMS cars LMP1 cars go to pros, LMP2 & LMGT cars to semi-pros. The winners in GT1 or LMP1 are official world champs pro endurance racing, the winners in GT2 or LMP2 & LMGT  world champs semi-pro endurance racing.

Art. 5: COMMON RULES AT IMCA MODEL CAR EVENTS
5.1. BASIC PRINCIPLE OF MARSHALLING, LANE ROTATION & ENCLOSED ZONE
(a.1.) THE MARSHALS -  All marshalling is exclusively done by the racers of the previous heat, the racers of the last heat being marshal at the first series.  Only marshals can touch a deslotted car. This principle doesn't hold for cars deslotting in front of the drivers stands.
(a2) MARSHALLING DURING THE NIGHT AND LOCAL LAWS ON MINORS - In several countries its NOT allowed that racers younger than full 18 years should compete during the whole night. Where such law is the case marshalling at the night section is to be done by the team mate(s) so that 6 hours of sleep is guaranteed for everybody.
(b) BAD MARSHALLING & YELLING - Putting a car on a wrong lane costs at least 5 laps. Should it be obvious that the error was intentioned the marshal is excluded. The race director has always the right to replace a too slow marshal by someone else. Yelling at the marshals is sanctioned in 3 steps by warning, 5 laps and exclusion.
(c) LANE ROTATION AT MODEL CAR RACES is done by those marshals being the closest to the cars. They change the lane stickers and put within the minute the car(s) on their new lane.  There is absolutely no work on the cars during rotation on sanction of disqualification. 
(d) ENCLOSED ZONE - On sanction of exclusion - nobody but the race directors can touch the cars in the enclosed zone. Cars leave the enclosed zone only for racing or for repairs. They are put on the track by the race directors.
5.2. RETIRED CARS & RANKING ORDER
(a) RETIREMENT - is necessary when a car is beyond repair or black flagged.
(b) RANK ORDER & RESULTS - Eliminated racers at the Consis are always classified behind eliminated racers at the Quarters. Racers eliminated at the Quarters are always ranked behind racers doing the Semis. Eliminated racers at the Semis are always classified behind racers having done the Main. However, all disqualified racers and ALL racers having been enforced to retire (due to technical problems or black flag) are always classified behind ALL racers having been not disqualified and having finished the race.
5.3. MISCELLANEOUS
(a) RACE DIRECTOR & SCRUTINIZERS - At IMCA meetings race direction and scrutinizing goes exclusively to non-racers.
(b) LAP COUNTER FAILURE - The lap counter is automatically corrected for all laps 0.2 seconds faster than the track record. In all other situations only the lap counter results are considered.
(c) CONTROLLERS - Racers can use their own controllers under condition that they are not increasing the power. Controllers must be mass produced and available in large quantities on the market. For FIA GT races there exists a special rule on controllers sub art. 7.
(d) TRACK CALLS - Only allowed (i) on debris in the slot, (ii) on power failure, and (iii) on non-marshable car(s). Any non-authorized track call results in a 3-lap penalty on behalf of the caller.
(e) LOW VOICE - On the same sanctions as sub art. 5.1.b the race direction may hear at model car races from the racers no other words than "Double!", "Under the bridge", or "Track!" on track call.
