What is a Commercial Driver’s License?

I think we can all agree that driving a CMV is a lot different than driving that car in your driveway. A CMV takes a higher level of knowledge and skill along with some experience to operate it safely and properly. This is one of the main reasons that you will have to apply for and earn a commercial driver’s license.

In October 1987, the federal government signed in to law that started to require that anyone who wants or does drive a CMV must obtain a commercial driver’s license by passing a series of examinations. This was to ensure that drivers of CMVs including tractors and buses were adequately qualified to do so. This in turn would remove unsafe drivers from the roadways and hopefully prevent a large number of traffic accidents and deaths.

There are three different classifications for commercial driver’s licenses namely A, B and C. Click on the tab below to tell the difference.

What is the CDL Exam Like?

If you want to enjoy a profitable and exciting career as a truck driver, then you will need to pass the commercial driver’s license exam from your state’s Department of Motor Vehicles (DMV). The CDL exam contains both written test and skills demonstrations that must be passed in order to obtain the license. If you are also going to add an endorsement on to your CDL, you will need to pass the written test for that endorsement too.

Written Test

The written test for a commercial driver’s license covers general knowledge including some of the following subjects:

  • Highway Safety
  • Highway Signs and Markers
  • Knowledge of Truck or Vehicle
  • Pre-Trip Inspection
  • General Driving Questions
Skills Demonstration

Typically this part of the commercial driver’s license exam needs to be scheduled a head of time so you have an appointment. You will have to show your learned skills on driving with an inspector sitting next to you. This test is generally broken out in to three separate categories that you will need complete adequately to move on.

  • Pre-Trip Vehicle Inspection
  • Basic Vehicle Control
  • On-Road Test
In other words, you will have to prove that you have gained the necessary skill, knowledge and experience to drive a CMV to be able to get your commercial driver’s license.

You can try our practice knowledge test found right here.
