Doubles & Triples CDL Test Information

Driving double and triple trailer combination vehicles are challenging because they don't stop or turn as well as other vehicles. This practice test will help you understand how to uncouple and couple correctly, how important it is to be careful when driving with more than one trailer, and how to inspect trailers properly.

It is imperative that you pay attention to the questions regarding the air supply system on double and triple trailer combination vehicles. The doubles and triples endorsement test must be taken by anyone who wants to drive a multiple trailer combination vehicle. You must score an 80% or better to pass the doubles and triples test.
