Unsuspecting passengers get the opportunity to earn thousands of dollars when they hail an ordinary-looking taxi and answer questions correctly on this hilarious game show. Ben Bailey, the host and driver of Cash Cab, then offers them the following proposition:
The Cash Cab will drive you all the way to your destination and ask you general knowledge questions along the way. The questions start out on the easy side, then get harder along the way - the harder the question, the more money it's worth. The first four questions are worth $25 for each correct answer. The next four are worth $50 and then every question after that is worth $100.
A correct answer is awarded the cash, an incorrect answer means the contestant gets a strike. The contestants can earn cash all the way to their destination. But the second they miss their third question (i.e., earn their third strike), Ben pulls the Cash Cab over and ejects them onto the sidewalk, no matter where they are!
