The Double/Triple Trailers (T) Study Guide System

The Double/Triple trailers (T endorsement) license will allow you to haul double and triple trailers in the states where it's legal. The Double/Triple trailer endorsement requires you to understand sensory feedback, yaw stability and rollover during steady turns, response to steering, oscillatory sway, and off-tracking. You'll need to know the correct placement of trailers, how to couple and uncouple double and triple trailers, what issues you can run into when pulling multiple trailers, and how to inspect air brakes (among other operating procedures).

If you want to pass your Double/Triple trailers endorsement test the first time, you're in luck - we have a powerful study and practice test portal designed to quickly give you the knowloedge you need. Our study guide will help you prepare for the types of questions you'll run into when you take the test, and the practice test portal will let you see where you're at in your studies.

You can check out just the Double/Triple trailers study guide or the practice test separately, or you can get both for the best value. Either way, our study materials will help you ace the test so you can get your T endorsement the first time and be on your way. We guarantee it!
