How Much Does the CDL Written Test Cost?

The total cost of getting your CDL depends on your state and the endorsements you choose. Fees vary widely, so the numbers below are typical ranges rather than exact figures from every state.

Written Test and Permit Fees

The written knowledge test itself is often included in, or bundled with, the CLP application fee. Expect to pay roughly:

• CLP / written test: $30–$75 depending on the state.
• Endorsement tests: extra, but usually just a few dollars each, often bundled.

Some states charge a separate test fee even if the permit fee is lower. Check your local DMV fee schedule.

Skills Test Fees

After passing the written portion, the skills test is the bigger expense:

• Third-party tester: $150–$400 or more.
• State-administered: often cheaper but less available.

The cost depends heavily on whether testing is done by the state or by a private third party, and on the vehicle used.

Costs That Add Up

Don’t forget the surrounding expenses:

• Medical certificate exam.
• Background checks (especially for hazmat).
• Training programs, if you choose a school.
• Retake fees, if you don’t pass the first time.

How to Save Money

Study costs nothing but time. The free practice tests here help you pass the written exam the first time, so you avoid retake fees and extra rebooking charges.

The written test is the cheapest part, but it’s also the gatekeeper — fail it and you can’t even schedule your skills test.

Bottom Line

Plan for at least $100–$500 in testing fees, plus training and certification if you need them. Passing the written test on the first try is one of the easiest ways to keep your total cost down.
