CDL Endorsements Practice Tests FAQs:

What CDL endorsements do I need?

The specific CDL endorsements you should apply for are dependent on your class of CDL and what type of driving your job requires you to do. For example, if you’re carrying 16 or more passengers, you’ll need a “P” endorsement—but if you’re driving a school bus, you’ll need an “S” endorsement. If you haven’t yet earned your CDL but you’re already employed, your employer will tell you which endorsements you need. If you’re looking to earn a CDL to make yourself more marketable, research the type of driving you wish to do and decide on endorsements from there.

Can I have more than one commercial license endorsement?

Yes, you can have multiple CDL endorsements depending on what truck you’re driving and what cargo you’re carrying.

What class of CDL do I need?

Your CDL class depends on what type of vehicle you’ll be driving. Class A CDLs cover any combination of vehicles that together weigh 26,001 pounds or more with the towed vehicle being heavier than 10,000 pounds; a Class B CDL covers a single vehicle weighing 26,001 points or heavier or to tow a vehicle weighing 10,000 pounds or less; a Class C CDL is required for carrying HAZMAT or driving passenger vehicles, as well as any other vehicle not covered by a Class A or B license.
