CDL licenses are valid for eight years from the date of issue, though some states issue them for shorter periods

A Commercial Driver's License (CDL) is good for eight years in most states. The expiration date is printed on the front of your card. However, a few states issue CDLs for five years instead, so check your state's rules or look at your card to see your exact expiration date.

Your CDL will not renew automatically. You must visit your state's Department of Motor Vehicles (DMV) or equivalent agency before the expiration date to renew it. If your license expires, you cannot legally operate a commercial vehicle, even if you are only one day past the date.

The renewal process usually takes a few weeks, so plan ahead. Some states allow you to renew online or by mail for your first renewal, but most require you to appear in person and pass a written test again.

Key Takeaways

  • Most CDL licenses expire eight years after the date they are issued, though some states use a five-year cycle.
  • Your expiration date is printed on the front of your license card, so check it now to know when you need to renew.
  • CDL licenses do not renew automatically — you must visit your state's DMV before the expiration date or your license becomes invalid.
  • Renewal usually requires passing a written test again and may require a medical examination, depending on your state and the type of CDL you hold.
  • Starting the renewal process at least two months before your expiration date gives you time to schedule an appointment and pass any required tests.

What happens if your CDL expires

Once your CDL expires, you cannot legally drive a commercial vehicle. Driving with an expired license is a violation in every state and can result in fines, a citation, or both. If you are caught driving commercially with an expired CDL, your employer may also face penalties.

If your license has been expired for less than a year in most states, you can renew it without retaking the written test — you only need to visit the DMV and pay the renewal fee. However, if it has been expired for more than a year, you may have to retake the written exam and possibly the skills test as well. Rules vary by state, so contact your DMV to find out what applies to you.

Medical certification and CDL renewal

Most CDL holders must also maintain a valid medical certificate from a certified medical examiner. This certificate is separate from your CDL itself and has its own expiration date, usually two years from the date of the exam. If your medical certificate expires before your CDL does, you cannot legally drive a commercial vehicle until you renew it.

When you renew your CDL, you will need to show proof of a current medical certificate. If your medical certificate has expired, you must schedule an exam with a certified medical examiner before you can complete your CDL renewal. The examiner checks your vision, hearing, blood pressure, and other health factors to may support you are safe to operate a commercial vehicle.

A few states and certain types of CDL operations have different medical rules, so check with your state's DMV about what applies to your situation.

Renewing your CDL before it expires

You can renew your CDL up to one year before it expires in most states. Starting early gives you time to schedule an appointment, especially if your DMV has a long wait list. Many DMVs now use online scheduling systems, so you can book a time slot weeks in advance.

Bring your current CDL, proof of residency, and your medical certificate (if required) to your renewal appointment. Some states also ask for proof of citizenship or a valid passport. Check your state's DMV website for the exact list of documents you need before you go.

The renewal fee varies by state but typically ranges from $50 to $150. Some states charge more if you are renewing a CDL with hazmat or passenger endorsements. Payment methods vary — some DMVs accept credit cards, while others require cash or check.

Written test and skills test during renewal

Most states require you to retake the written test when you renew your CDL, even if your license is not expired. The written test covers the same material as the original CDL test — road rules, safe driving practices, and vehicle operation. You can study using your state's CDL manual, which is available free on your state's DMV website.

The skills test (the driving test) is usually not required for renewal if your license is still valid. However, if your license has been expired for more than a year, or if your state has specific rules about skills testing, you may have to take the driving test again. Some states also require a skills test if you are adding a new endorsement, such as hazmat or passenger.

If you fail the written test, you can usually retake it the same day or schedule another appointment. Most states allow you three to five attempts before you have to wait a set period before trying again.

CDL endorsements and their expiration

If your CDL includes endorsements such as hazmat (hazardous materials), passenger, or tanker, those endorsements expire on the same date as your main CDL. You do not renew endorsements separately — they renew when you renew your license.

However, hazmat endorsements have an additional requirement: you must pass a federal background check every time you renew. This check takes a few weeks, so explore for hazmat renewal well before your expiration date. Some states require the background check to be completed before you can renew the endorsement.

If you let your hazmat endorsement expire, you can renew it when you renew your CDL, but you will have to pass the background check again. Plan for this extra step if hazmat is part of your job.

Keeping track of your CDL expiration date

The easiest way to remember when your CDL expires is to write the date on your calendar or set a phone reminder for two months before the expiration date. This gives you time to schedule a DMV appointment and handle any unexpected delays.

You can also check your state's DMV website — many states have online systems where you can log in and see your license status and expiration date. Some states send renewal reminders by mail about 60 days before your license expires, but do not rely on this alone, as mail can be delayed or lost.

If you are unsure of your expiration date, look at the front of your CDL card. The expiration date is printed clearly and is usually formatted as MM/DD/YYYY. If you cannot find your card, contact your state's DMV and provide your driver's license number — they can tell you the exact date.

Frequently Asked Questions

Can I drive a commercial vehicle if my CDL is expired but I have already scheduled a renewal appointment?

No. You cannot legally drive a commercial vehicle once your CDL expires, even if you have a renewal appointment scheduled. If you are caught driving commercially with an expired license, you face fines and a citation. Schedule your renewal appointment well before your expiration date to avoid this situation.

What if my medical certificate expires before my CDL does?

Your medical certificate must be current to drive commercially. If it expires before your CDL, you cannot legally operate a commercial vehicle until you renew the medical certificate. Schedule your medical exam before the certificate expires so there is no gap in your coverage.

Do I have to retake the skills test when I renew my CDL?

Most states do not require a skills test for renewal if your license is still valid. However, if your license has been expired for more than a year, or if you are adding a new endorsement, you may have to take the driving test again. Check with your state's DMV about their specific renewal rules.

How much does it cost to renew a CDL?

CDL renewal fees vary by state but typically range from $50 to $150. Some states charge extra if you hold hazmat or passenger endorsements. Check your state's DMV website for the exact fee and accepted payment methods.

Can I renew my CDL online?

Some states allow online renewal for certain situations, but most require you to appear in person at the DMV. Even if online renewal is available, you usually still need to pass a written test, which may require an in-person visit. Contact your state's DMV to find out what options are available to you.
