Rule 10.2.13.1 reads: “Should a SC deployment end eight (8) laps or less from the last lap of a race, or ten (10) minutes or less prior to the time certain finish time of a race as published in the Supplementary Regulations or as amended by the Stewards, any Car that is one (1) or more laps behind the leader must reposition itself by driving through the Pit Lane so that it is not in front of any Car that is on the lead lap.”
