Additionally, that season's four-member-team format required some Roadblocks to be completed by two people. The six-Roadblock limit was dropped for only Season 8 due to the teams being four-person families.

While this Roadblock rule has not been specifically mentioned in some later seasons, team behavior and statements (such as Eric in Season 11) imply that it still applies. Many speculate that this rule was enacted because the male member in male-female teams would dominate and perform the majority of the tasks, especially in Season 5 where the final three teams were all male-female Roadblocks with the roadblock records of 11-1 or 10-1. Since there are normally twelve Roadblocks in the Race, this rule forces each team to split the Roadblocks equally between the two members (unless a team uses a Fast Forward to skip one Roadblock, in which case the split can be 6-5).

The participating team members from other teams are able to help each other, however, unless otherwise indicated by the clue. Season 20's first roadblock was similar, in that the non-participating team member had to skydive out of a plane, while the participating teammate had to use a map to find the landing zone of their partner and reunite with them to receive their next clue (but in The Amazing Race: All-Stars, it was the final challenge). A similar arrangement occurred in the final Roadblock in Season 10, where while the selected member skydived out of a plane, the other member was treated to a 'surprise' nosedive of the plane itself after the start of the skydive. In a select few Roadblocks, the team member that did not opt to do it may be required to participate for example, in Season 1, one Roadblock required the selected team member to ride a camel, while the other team member was forced to walk along aside it to the next clue box.

Unless the clue indicates otherwise, the other teammate(s) cannot assist in the task though they may verbally offer advice and encouragement, usually standing in a designated area off to the side. Season 25 was the first US season in which a Roadblock has not appeared in two consecutive legs (Leg 2 and 3) since the Israeli Season 2 hadР’В no Roadblock on 3 consecutive legs (Leg 11 - Leg 13). In Season 1, even the first leg had a Roadblock, but it was not originally aired it was, however, included as an extra in the DVD release.(released in 2005) Season 10 became the first season to have and air a Roadblock on Leg 1, followed by the second season of the Latin American version (that didn't air the second leg's roadblock). ( Season 17)Р”Р„ Roadblock is featured (although, in some episodes, not aired) in every leg except the first one.

If a team chooses to forfeit a Roadblock, they will incur a 4-hour penalty by default (unless otherwise stated). Once a choice has been made, the teammates cannot switch roles. They then must decide which team member would be best suited to complete it. Often, a team may figure out the specific task by observing their surroundings, using common sense, or even seeing other teams already performing the Roadblock task. Before heading into a Roadblock, teams read a vague clue about the task to come, e.g., ' Who's really hungry?' (for an ostrich-egg eating challenge), or ' Who wants to get down and dirty?' (for a task involving making mud bricks).
