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 practice tests include:

General Knowledge Tests

The largest of the CDL tests covering 23 topics, including vehicle inspections, driving safely, and everything in between. All of the CDL classes are required to pass a general knowledge test.

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. This CDL practice test covers everything that you are required to know to get the hazmat endorsement and transport hazardous materials according to the Code of Federal Regulations.

Tanker Test

This CDL endorsement is required to transport any liquid material in a tank that has an individual rated capacity of more than 119 gallons and an aggregate rated capacity of 1,000 gallons or more. We have all of the test questions needed to pass the tanker endorsement test.

School Bus

This practice test covers all of the required questions needed to pass and obtain a CDL to drive a school bus. School bus drivers are also required to pass the general knowledge test, and air brakes test if needed.

Passenger Vehicles

A complete practice test, covering every topic of the passenger or "Class C " driver’s license required for transporting 16 passengers, or more including the driver. If the passenger vehicle you will be driving has air brakes, you will be required to pass that CDL test as well.
