This season introduced two new twists to "The Amazing Race": the U-Turn and the Speed Bump. Positioned just after a Detour, the U-Turn allowed one team to force a team behind them to complete both sides of that Detour. The Speed Bump was a penalty task for a team that finished last in a non-elimination leg, to be completed during the next leg in addition to other tasks. The U-Turn and the Speed Bump each occurred in two episodes of "The Amazing Race 12".
