CDL Practice Test - About the Commercial Drivers License Written Test

About the CDL Written
Before you can even step foot in a commercial vehicle, you must first pass the your state's CDL written test. The CDL permit test consists of the general knowledge test and depending on what type of vehicle you plan on driving possibly several other endorsement tests.

For example, if you want to drive a tractor trailer equipped with air brakes and transporting hazardous material, you must take the general knowledge test, the combination vehicle endorsement test, the air brakes endorsement test, and the hazmat endorsement test. If you want to drive a box truck with hydraulic brakes you are only required to pass the general knowledge test.

What Will the CDL Written Look Like?
Each state has a different written test format, but all the test questions and answers are nearly the same. For example, in Florida the written test is taken on a computer and each question has a time limit. In another state the written test may be taken on paper and there may be no time limit.

In most states the general knowledge test is 50 questions and the rest of the endorsements are about 25 questions. You can take as many written tests as you want in one day. You can always go back to the DMV to get more endorsements. For example, when you first took the written test you only wanted to drive a combination vehicle with air brakes. Ten years later you now want to drive a tanker truck, so you study for the tank endorsement and pass the tanker endorsement test at the DMV. The DMV will issue you a new license with the new tanker endorsement.

Preparing for the CDL
To prepare for the written test you can go to the DMV and get the handbook. You can also go online to and get all your CDL practice tests and CDL test answers. Don't just memorize the answers understand them. Practice until you are perfect, there is no sense in going to the DMV unless you are completely prepared. If you got your CDL practice tests online print them out and study them while waiting at the DMV.
