A Roadblock is a task that only one team member may perform. A Roadblock clue is given as a cryptic question, such as ""Who's really hungry?"" (leading to task involving exotic food) or ""Who wants to get down and dirty?"" (for a task related to laundry). Based on this information and observation of any other racers at the task, the team must declare which member will complete the task before reading the full task description. Once a team announces its decision of who will complete the Roadblock, it cannot be changed or taken back. The Roadblock task is performed by only the selected racer while his or her partner waits in a designated area, although the partner is sometimes able to supply words of encouragement and advice. Unless directed by the task instructions, the selected racer may gain help from other racers that have been selected to do the Roadblock or from locals. Some Roadblocks may involve the non-selected racer, such as leading a camel his or her partner rides, or helping his or her partner solve a puzzle. On completing the Roadblock, the selected racer receives their next clue, at which point they may return to their partner and continue on. Should a racer be unable to complete a Roadblock, or opts to quit, the team must take a four-hour penalty, which either starts when the next team arrives at the Roadblock, or if all teams are present, when they reach the Pit Stop for that leg. Some legs feature two Roadblocks, each of which must be completed by different teammates.
