Before you get started
Prefer a printed version?
Visit a driver licensing office to get printed copies of the CDL and supplemental guide. If you live out of state or can't get to an office, call us and we'll send you the guides free of charge.
You can also download the commercial driver guide and the supplemental guide to print at home.
We implemented AAMVA’s CDL Modernized Skills Test. The road test will remain the same, but the vehicle inspection and basic control segments of the skills test have changed. Sections 11 and 12 of the CDL guide have been replaced with a supplemental guide where you can find these updates. You must study the vehicle inspection and basic control segments from the supplemental guide.
