All teams must abide by the rules set at the beginning of the race, and teams are given time penalties for any rule infraction, which can negatively affect finishing position in that leg of the race. Usually in a non-elimination leg, if the last team to arrive at the mat is checked in before a previous team has completed its penalty, any remainder of the penalty time will be applied at the start of the next leg of the race, beginning at the departure time of the next-to-last team.; in some cases, if multiple teams are penalized and were the last set of teams to arrive, the teams who did not finish last (as long as their penalties does not affect the placements) are allowed to check-in immediately with the penalty to be applied at the start of the next leg. In a no-rest leg, the last team will be given their next clue immediately while any remainder of the penalty will be removed.
