Make Your CDL Work for You: How to Remove Restrictions from Your CDL

Aug 14 / Erin Ford
You did it! You took all the training, passed all the tests, and got your CDL. You’ve put in so much hard work and have so many new career opportunities, but the restrictions on your CDL are limiting the vehicles you can drive and the jobs that you can take. While it may feel like the restrictions are slamming doors in your face, we can help you find the keys to reopen those doors.

What Are Restrictions?

Restrictions limit the types of vehicles you can operate. This is typically due to the vehicle you tested in or other conditions (like medical limitations). The good news? Most restrictions can be removed by retaking the proper written or skills test in the appropriate vehicle.

Here’s a breakdown of each restriction and how to remove it:

Restriction Code

What It Means

How to Remove

L

You didn’t pass the air brakes test or didn’t take the skills test in a vehicle with full air brakes. You can’t drive CMVs with full air brake systems.

Retake the written air brakes test, and/or retake the skills test in a vehicle with a full air brakes system.

Z

You tested in a vehicle with an air-over-hydraulic brake system. You’re not authorized to drive CMVs with full air brakes.

Retake the skills test in a vehicle with a full air brakes system.

E

You tested in a vehicle with an automatic transmission. You’re restricted from driving CMVs with a manual transmission.

Retake the skills test in a vehicle with a manual transmission.

O

You tested in a Class A vehicle with a pintle hook or non-fifth wheel connection. You can’t operate Class A vehicles with a fifth wheel connection.

Retake the skills test in a Class A vehicle with a fifth wheel connection.

M

You have a Class A CDL but earned your Passenger or School Bus endorsement in a Class B vehicle. You're restricted to operating Class B and C passenger vehicles or school buses.

Retake the Passenger or School Bus skills test in a Class A vehicle.

N

You have a Class B CDL but earned your Passenger or School Bus endorsement in a Class C vehicle. You're restricted to Class C passenger vehicles or school buses.

Retake the Passenger or School bus skills test in a Class B vehicle.

V

You have a medical variance on file with FMCSA (e.g., vision or insulin use). This must be noted on your CDL and driving record.

Talk with your doctor to see if there are any treatment plans that would let the restriction be removed.


Bottom Line: 

Aside from the medical restriction (V), removing restrictions is as simple as retesting in a qualifying vehicle.

You may not want or need to remove your restrictions, but having few restrictions, along with many endorsements, on your license will make you a more specialized driver, which can lead to higher pay.

Always check with your state DMV or licensing authority—requirements may vary slightly by location.
