CDL Renewal Requirements by State

Your CDL is not a one-and-done credential — it must be renewed periodically, and your DOT medical certificate must be renewed every 2 years regardless of your CDL renewal cycle. If your medical certificate expires, your CDL will be downgraded to a non-commercial license until you submit a new medical certificate. Missing your renewal deadline can also result in having to retake tests.

This guide covers CDL renewal requirements for all 51 states in our database — renewal cycles, fees, and medical certificate requirements. All per-state data is pulled from our verified state databases.

The Medical Certificate: Your Most Frequent Renewal

Critical: DOT Medical Certificate

Renewal frequency: Every 2 years maximum (some drivers receive shorter certificates based on medical conditions)

What it is: Medical Examiner's Certificate (MEC), Form MCSA-5876

Who performs it: Must be conducted by a medical examiner listed on the FMCSA National Registry of Certified Medical Examiners (NRCME)

What happens if it expires: Your state will downgrade your CDL to a non-commercial driver's license. You cannot operate a CMV until you submit a new valid medical certificate.

Cost: Typically $80–$150 for the DOT physical (not covered by most health insurance)

Self-Certification Categories

When you apply for or renew a CDL, you must self-certify which operating category applies to you. This determines whether you need a medical certificate:

Interstate Non-Excepted: Operates in interstate commerce; must meet federal DOT medical requirements

Interstate Excepted: Operates in interstate commerce but is exempt from federal DOT medical requirements (e.g., certain federal/military/government drivers)

Intrastate Non-Excepted: Operates only in intrastate commerce; must meet state medical requirements

Intrastate Excepted: Operates only in intrastate commerce and is exempt from state medical requirements

FMCSA Drug & Alcohol Clearinghouse

The FMCSA Drug & Alcohol Clearinghouse is a federal database that tracks drug and alcohol program violations for CDL holders. While it is not technically part of the CDL renewal process, it directly affects your ability to operate:

Employers must query the Clearinghouse before hiring any CDL driver and at least once annually for current drivers
Query fee: $1.25 per query per query
Phase II (effective November 18, 2024): State DMVs must now revoke commercial driving privileges for drivers with a prohibited status in the Clearinghouse
Drivers can register and view their own record at clearinghouse.fmcsa.dot.gov

What Happens If Your CDL Expires?

Medical certificate expires

Your CDL is downgraded to a regular (non-commercial) driver's license. You cannot operate any CMV. Once you provide a new valid medical certificate, your CDL privileges are typically restored without retesting.

CDL expires but within grace period

Most states offer a grace period for late renewal. You may be able to renew without retesting, though late fees may apply. Check your state's specific grace period — it varies.

CDL expired beyond grace period

You may need to retake the knowledge test, skills test, or both. Some states treat a long-expired CDL as a new application. ELDT requirements may also apply.

Special Renewal: HazMat Endorsement

The HazMat (H) endorsement has its own renewal requirements on top of regular CDL renewal:

TSA security threat assessment: Must be renewed every 5 years ($85.25 fee). This is a federal requirement regardless of your state's CDL renewal cycle.
Knowledge test: You must retake the HazMat knowledge test at each renewal in most states.
Timing: Start your TSA renewal 90+ days before expiration to avoid a gap in endorsement status.

CDL Renewal Checklist

Track both dates: Your CDL renewal date AND your medical certificate expiration date. They are independent.
Schedule your DOT physical early: Don't wait until the last week. Some medical conditions require follow-up.
Check for online renewal: Many states now allow online CDL renewal if you meet eligibility requirements.
Update your Clearinghouse registration: Make sure your information is current.
Budget for the medical exam: $80–$150 every 2 years, plus any specialist referrals required by the examiner.
HazMat holders: Start TSA renewal 90+ days before expiration and budget for retesting.

What Happens If Your CDL Expires?

Medical certificate expires

CDL expires but within grace period

Most states offer a grace period for late renewal. You may be able to renew without retesting, though late fees may apply. Check your state's specific grace period — it varies.

CDL expired beyond grace period

You may need to retake the knowledge test, skills test, or both. Some states treat a long-expired CDL as a new application. ELDT requirements may also apply.

Special Renewal: HazMat Endorsement

The HazMat (H) endorsement has its own renewal requirements on top of regular CDL renewal:

TSA security threat assessment: Must be renewed every 5 years ($85.25 fee). This is a federal requirement regardless of your state's CDL renewal cycle.
Knowledge test: You must retake the HazMat knowledge test at each renewal in most states.
Timing: Start your TSA renewal 90+ days before expiration to avoid a gap in endorsement status.

CDL Renewal Checklist

Track both dates: Your CDL renewal date AND your medical certificate expiration date. They are independent.
Schedule your DOT physical early: Don't wait until the last week. Some medical conditions require follow-up.
Check for online renewal: Many states now allow online CDL renewal if you meet eligibility requirements.
Update your Clearinghouse registration: Make sure your information is current.
Budget for the medical exam: $80–$150 every 2 years, plus any specialist referrals required by the examiner.
HazMat holders: Start TSA renewal 90+ days before expiration and budget for retesting.
