About the Virginia Combination Vehicles test
The questions come from the Virginia CDL manual, they are multiple choice, and you need 80% to pass, the same standard as every other CDL knowledge test. Virginia Department of Motor Vehicles gives it, and you sit it on top of the General Knowledge test rather than instead of it.
Combination Vehicles is a core knowledge test for Class A, not an add-on endorsement. It covers what changes once there is a trailer behind you: coupling and uncoupling, the extra inspection points, how a combination behaves in a turn or a skid, and what to do when a trailer starts to swing.
What it covers
Our 8 free questions and the full 65-question Combination Vehicles bank are drawn from these manual sections:
- Driving Combination Vehicles Safely

Common questions
How long is the combination vehicles test?
Your state sets the number of questions. Federal rules require a set number drawn from an approved pool but do not publish a per-test count, so Virginia Department of Motor Vehicles decides the length. The pass mark is 80%.
Who needs to take it?
Anyone going for a Class A license. It is a core knowledge test for that class rather than an endorsement, so it is not optional and nothing is added to your license for passing it: it is part of qualifying.
What does it cover?
The combination vehicles section of the CDL manual: coupling and uncoupling, the extra inspection points a combination adds, how to keep a trailer from swinging in a turn or a skid, and the rollover and off-tracking behavior that a trailer introduces.
Is this the same as the doubles and triples test?
No. Combination Vehicles is the core Class A test and covers one trailer. Doubles and triples is a separate endorsement (T) for pulling more than one trailer, and it has its own knowledge test on top of this one.
