How IMSA Enforces Pit Lane Speed Limits and Penalties

The Fixed Speed Ceiling

In the IMSA WeatherTech SportsCar Championship, cars navigating pit road must adhere to a strict maximum speed of 60 km/h across every competing class. This ceiling protects servicing personnel working in close proximity to moving machinery, operating alongside strict limits on when crew members can cross the wall and how many may touch the car during a stop.

Penalties for Speeding

Drivers who breach the IMSA pit lane speed limit rules are typically issued a drive-through penalty by race control. Serving this sanction requires entering pit lane, driving its entire length at or below the 60 km/h limit without stopping for tyres, fuel, or servicing, and rejoining the circuit.

If a competitor fails to follow penalty instructions or engages in severe noncompliance, race control can escalate the intervention by issuing a black flag, ordering the car to enter the pits immediately.
