About our CDL Tests

Each of our practice tests is updated each year with current information from each State CDL Manual and the Federal Motor Carrier Safety Administration. The free practice tests found on this site include:

General Knowledge Tests

Air Brakes

These CDL practice tests cover all of the in-cab brake tests, including static leakage, low-pressure warning, parking, and service brake checks. If your vehicle has air brakes, you will be required to pass this test.

Combination Vehicles

All Class A commercial drivers are required to pass this test. These CDL test questions cover everything from coupling trailers to driving combination vehicles safely.

Hazmat Test

To transport hazardous materials, commercial drivers are required to have an endorsement on their commercial driver's license.
