CDL Hazmat Test

A Brief Guide to the Commercial Drivers License

Commercial truck drivers earn excellent pay and benefits and are almost guaranteed employment in this in-demand field. However, applicants for a commercial drivers license are often confused by federal and state requirements. To make matters worse, failure of the General Knowledge test, required for all CDL applicants, and/or one or more endorsement tests is common. Some states report more than 50,000 failures on the CDL test every year.

Basic requirements for a CDL include:

Residency in the state in which you will be licensed
Being at least 18 years of age to drive within your own state and at least 21 years of age to drive out-of-state
A medical exam, vision screening, and drug test
Proof of your social security number
No active driver's license suspensions or revocations in any state
Passing all applicable background screens
Surrendering your state driver license once you earn a CDL

 

 

All Commercial Driver's License applicants must pass the written General Knowledge test. Written tests for other endorsements may also be required, depending on the type of vehicle you wish to drive. For example, if you wish to drive a bus equipped with air brakes you must take the passenger endorsement and air brakes endorsement on top of the general knowledge test. In addition, one or more skills tests will be required.

Endorsements include:

-T: Double/Triple Trailers (knowledge test only) 

-P: Passenger (knowledge and skills tests)

-N: Tank Vehicle (knowledge test only)

-H: Hazardous Materials (knowledge test only)

-X: Combination of Tank Vehicle and Hazardous Materials

In addition, many states have their own endorsements and accompanying tests.

 

If a driver either fails the air brake component of the general knowledge test or performs the skills test in a vehicle not equipped with air brakes, the driver is issued an air brake restriction, restricting the driver from operating a CMV equipped with air brakes.

Once you know what endorsements you need, you can begin studying for the CDL test(s). Many applicants fail these tests at least once, so you'll want to invest time and energy in studying. CDL practice tests help you review the CDL handbook in a way that facilitates the learning process by forcing you to interact with the material, rather than merely reading it.
