Who is Eligible to Receive A CDL?

Now that you know the requirements that you will need in order to get a CDL, let’s learn more about the eligibility to get one. This will better help you determine if getting a CDL is possible for you.

• You must be 18 years of age to obtain a CDL for in-state driving. If your job requires you to drive out of state, you must be at least 21. Additionally, if you are going to haul hazardous materials, you will also need to be 21.
• You must have no prior criminal convictions that may disqualify you such as certain felonies.

There are three types of CDL classes that determine the type of vehicle you may drive and how much you may tow. A Class A CDL class allows you to operate a vehicle with a GCWR of 26,001 if the vehicle you tow weighs more than 10,000 and a Class B CDL allows you to operate a vehicle with a GVWR of 26,001 or more pounds or operate any vehicle towing another vehicle that weighs less than 10,000 GVWR. With a Class C CDL, you can operate a Class C vehicle that transports hazardous materials.
