Big fields at this weekend’s American Le Mans Series round at the famous Mosport circuit in Canada have forced series organisers to make changes to pit stop procedures.

The large grid of 30 cars will mean a realigned pitlane operation for the race. During yellow-flag caution periods the pit entrance will be closed immediately, as is standard practice. Once the Safety Car has the overall leader and field in tow, IMSA officials will open the pits with LMP and LMPC cars only allowed to pit on the first lap. On the next lap, all GT and GTC cars may pit. For subsequent laps, any car may come in to pit lane.

The only exceptions are if a car has damage such as a flat tire or would run out of fuel before it would make it back around to an open pit. Such a car may only pit to make the immediate repair; the crew may not perform a full service with the pits closed.

The wave-by procedures following the round of pitstops will remain the same. The Safety Car will wave by to the nearest class leader, and that will be the order until the restart.
