Double and triple vehicles are heavier, longer, and more complex than even standard combination vehicles. A special endorsement is required to drive them (note: "triples" are not legal in all states). This means that drivers of double and triple vehicles need more knowledge and skill than other drivers. This test focuses on important safety factors that apply specifically to double and triple vehicles.

You must have a commercial driver license and have passed the Doubles and Triples test to drive such vehicles. To get the CDL, you must pass a written test.

Our CDLPass test preparation software will help you take and pass the Doubles and Triples test.
