Applying or Renewing Your CDL? Here’s What You Need to Know
What’s a CDL?
A Commercial Driver’s License (CDL) is a special type of license that allows you to legally drive large or specialized vehicles—like trucks, buses, or vehicles carrying hazardous materials. You’ll need a CDL if the vehicle you operate:Weighs 26,001 pounds or more (Gross Vehicle Weight Rating - GVWR), Transports 16 or more passengers (including the driver), Carries hazardous materials that require placards. It’s not just a license—it’s proof you’re trained, tested, and trusted to handle heavy-duty vehicles safely.
You’ll need a CDL if the vehicle you operate:
- Weighs 26,001 pounds or more (Gross Vehicle Weight Rating – GVWR)
- Transports 16 or more passengers (including the driver)
- Carries hazardous materials that require placards
It’s not just a license—it’s proof you’re trained, tested, and trusted to handle heavy-duty vehicles safely.
There’s no universal “filing season,” but here’s when you’ll need to apply:
- First-time drivers: As soon as you’re ready to begin a career in commercial driving
- Before your CLP expires: Your learner’s permit is valid for 180 days—don’t let it lapse!
- Before your license expires: Renewal deadlines vary by state, usually every 4–8 years
- When upgrading or adding endorsements: Like Hazmat or Passenger transport
- Before switching states: Some states require you to transfer your CDL within 30–60 days
Keeping track of your CDL status helps avoid penalties and delays in your career.
Getting a CDL takes a few steps, but we’ll keep it simple:
1. Check Eligibility:
- Must be at least 18 years old (21 for interstate or Hazmat driving)
- Hold a valid non-commercial driver’s license (DL)
- Pass a DOT medical exam
2. Get a Commercial Learner’s Permit (CLP):
- Apply at your local DMV
- Take a written knowledge test
Your CLP is valid for 180 days
3. Complete Training (Recommended):
Enroll in an Entry-Level Driver Training (ELDT) program. Training usually takes 3–6 weeks
4. Take the CDL Skills Test:
- Pre-trip inspection
- Basic vehicle control
- On-road driving
Must be done in person at a DMV or approved location
5. Pay Fees and Get Your CDL:
Fees vary by state but typically range from $50 to $150
Some states issue the CDL immediately, others by mail
Bonus Tip: Some states let you start the process online! Check your state’s DMV or the FMCSA website for details.
Each state sets its own CDL fees, but on average:
- CDL application fee: $50-$150
- Knowledge test fee: $5-$30
- Road skills test fee: $30-$100
- CDL endorsement fee: $10-$30 per endorsement
- Renewal fee: $50-$100 (depends on state and class)
- Medical exam fee: $50-$150 (if required)
Delaying your CDL application or renewal can lead to serious consequences:
- Driving without a valid CDL: Fines up to $5,000
- Expired license or endorsements: You can’t legally operate a CMV
- Missing required medical exams: Your CDL may be downgraded or suspended
- Violations like DUI or texting while driving a CMV: Can lead to suspension or even lifetime disqualification
Bottom line: keep your CDL current and compliant to avoid disruptions in your driving career—and heavy penalties.
Questions About CDL?
We’ve Got Answers!
Can I transfer my CDL from one state to another?
Yes. When you move to a new state, you must transfer your CDL within 30–60 days (varies by state). You’ll need to surrender your old CDL, provide proof of residency, and possibly retake written or vision tests depending on your endorsements and the new state’s requirements.
What disqualifies you from getting or holding a CDL?
Certain violations or medical issues can disqualify you from obtaining or keeping a CDL. These include DUI or drug-related offenses, using a CMV to commit a felony, serious traffic violations, or failing to meet the physical requirements outlined in a DOT medical exam.
Do I need a DOT medical exam to get a CDL?
Yes. All CDL applicants must pass a DOT (Department of Transportation) medical exam conducted by a certified medical examiner. You’ll receive a Medical Examiner’s Certificate (Form MCSA-5876), which you must keep valid and on file with your state’s licensing agency.
What’s the difference between a CDL and a DOT medical card?
Your CDL is your commercial driving license, while the DOT medical card (based on the Medical Examiner’s Certificate) proves you’re physically fit to operate a commercial motor vehicle. Most CDL drivers must carry a valid DOT card at all times and renew it every 1–2 years.
What happens if my DOT medical card expires?
If your medical card expires, your CDL can be downgraded to a non-commercial license. You may not legally operate a commercial vehicle until you submit a new, valid medical certificate to your state DMV. Some states allow a grace period, but penalties can include suspension or fines.
What is an out-of-service order, and how does it affect me?
An out-of-service order (OOS) means you or your vehicle cannot operate due to safety or legal violations. Driving under an OOS order can lead to fines up to $5,000 and CDL disqualification—even for a first offense. Employers can face penalties of up to $25,000.
Do all commercial drivers need a CDL?
No. You only need a CDL if you’re operating a vehicle that:
- Weighs 26,001 lbs or more (GVWR)
- Carries 16+ passengers (including the driver)
- Transports hazardous materials requiring placards
Smaller delivery trucks, RVs, and some construction vehicles may be exempt unless used for commercial purposes.
