Cash Cab
When the taxi had to stop at a red light and the contestant had at least $200, a "Red Light Challenge" was played. A question was asked that had more than one correct answer. The contestant had 30 seconds to give all of the correct answers to the question. If the contestant does so, $250 was added to their prize pool. If the 30 second time limit runs out, the contestant did not get a strike. In the early seasons, games had only one Red Light Challenge. Starting in the fourth season, some games had more than one. The second was played if the contestant had at least $1,000 in their prize pool.
