The U-Turn, introduced in season 12, allows a team to force another team to complete both Detour tasks in the leg. Similar to the Yield, a U-Turn marker board is placed on the route either immediately before or immediately after the Detour on certain legs and teams must pause at the marker to declare their intentions to employ or decline the U-Turn before continuing. The team choosing to U-Turn must stick a photo of the yielded team on the Yield marker, as well as a smaller photo of themselves onto an attached section labelled "Courtesy of". A team generally may exercise their U-Turn power once throughout the race, though in U.S. Season 29 and "The Amazing Race Canada", teams were allowed to U-Turn twice. If a U-Turned team is in possession of an Express Pass, it may use it to skip one — but not both — of the Detour tasks. If a team U-Turns a team which has already passed the marker, the U-Turn is nullified. As seen in the third Israeli season, one leg had two Detours and a U-Turn and the team who were subjected to the U-Turn was required to complete both Detours applicable for the first U-Turn only.
