CDL Written Test - How to pass the Commercial Driver Written Test

Written Test for CDL

by Martin

One of the many aspects of getting your CDL that you will have to go through is the written test. These tests aren’t as easy as the ones you get for a normal driver’s license. Instead, they require you to have a working knowledge of your truck and all the aspects of driving it safely on the road.

You will be asked certain questions regarding your driving history and what you should report to your employer as well. Each state has a different selection of questions that will appear on these written tests so make sure you are aware of your state’s regulations.

You will need to pass your written CDL test before you are allowed to get behind the wheel and take your driving and skills tests. The first part of your CDL training will help you immensely with the written section of your exams, and you should study everything in your manual to make sure that you can pass the written test with flying colors.

If you fail your written test, depending on state regulations, you will need to schedule a time to take another test. Most schools will also tell you which questions you should study up on.

The written test for your CDL will include things such as basic knowledge that you will need to operate on the roadways. It will also go over road regulations according to weight limits and vehicle size, which is very important for those that are transporting double, triple, and hazmat trailers.

If the vehicle you are going to be using requires air brakes, there will be questions about them on the written test as well. You will need to make sure that you do not fail this test more than 3 times or you will be required to wait 30 days before being able to take it again in most states.

Depending on what type of vehicle you are getting your license for will determine what the knowledge base of the written test is. This means that if you are going in to get a license to drive a school bus, for example, you will more than likely have a knowledge test about a school bus rather than driving a truck with double trailers. Your endorsements on your CDL will also be representative of your written tests as well.
