What License You Need to Tow
Whether you need a special license to tow depends on the weight of the vehicle you're towing and your state's rules. Most states don't require a separate "tow truck driver's license," but they do require you to upgrade your regular driver's license to a Commercial Driver's License (CDL) if the truck and trailer combination exceeds a certain weight threshold.
The federal threshold is 26,001 pounds of Gross Combined Weight Rating (GCWR) — that's the total weight the truck, trailer, and cargo can safely carry together. If you're towing a load that puts you over that number, you need a CDL. If you stay under it, your regular driver's license is usually enough, though some states set their own lower thresholds.
A few states also require a Tow Truck Endorsement or additional training beyond the CDL, but this is less common. You'll need to check your specific state's Department of Motor Vehicles (DMV) or equivalent agency to know what applies where you work.
Key Takeaways
- You need a CDL if the truck-and-trailer combination weighs more than 26,001 pounds GCWR, regardless of what you're towing.
- Some states set their own weight limits lower than the federal threshold, so check your state DMV's rules before you start towing commercially.
- A CDL requires passing a written knowledge test, a skills test with a vehicle, and a medical exam — not just upgrading your existing license.
- A few states require additional tow truck endorsements or certifications beyond the CDL, which may include classroom training or on-the-job requirements.
- If you're towing for a business (even part-time), you almost always need a CDL once you cross the weight threshold, even if you own the truck.
When the Weight Threshold Matters
The GCWR is what determines whether you need a CDL, not the type of vehicle or what you're towing. A heavy-duty pickup truck towing a loaded trailer can easily exceed 26,001 pounds. A light wrecker towing a compact car might not. You need to know the GCWR of your specific truck and the weight of what you're pulling.
If you're unsure, check the truck's door jamb or owner's manual for the GCWR, and weigh the load at a truck scale if necessary. Many tow operators make the mistake of thinking they're under the threshold when they're not, which can result in fines, license suspension, or liability issues if there's an accident.
Some states also look at the Gross Vehicle Weight Rating (GVWR) of the tow truck alone. If that exceeds a certain weight — often 10,001 pounds — you may need a CDL even if you're not towing anything. Again, this varies by state, so verify with your DMV.
Getting a CDL for Tow Truck Work
A CDL is not an add-on to your regular license — it's a separate class of license that requires its own testing and medical certification. To get one, you'll need to:
- Pass a medical exam by a certified Medical Examiner and get a Medical Certificate (USDOT form).
- Pass the CDL written knowledge test, which covers general driving rules, air brakes (if applicable), and combination vehicles.
- Pass a skills test in an actual commercial vehicle, which includes a pre-trip inspection, basic controls, and an on-road drive.
- Pay the licensing fee, which varies by state but typically ranges from $50 to $200.
You can study for the written test using your state's CDL manual, which is free and available online from your DMV. Many people take a CDL training course — either in-person or online — to prepare, though it's not always required. Some employers require it; others don't.
The skills test must be taken in a vehicle that matches the type of work you'll do. If you're towing, you'll need to bring a truck and trailer combination to the test site. Some testing facilities provide vehicles, but you'll need to check with your local DMV.
State-Specific Rules and Endorsements
A handful of states add their own requirements on top of the CDL. Some require a Tow Truck Endorsement or Wrecker Endorsement, which may involve additional classroom hours, on-the-job training, or a separate exam. States that commonly require this include Texas, Florida, and a few others, though the rules change.
A few states also require tow truck operators to hold a separate occupational license or permit from the state, independent of the driver's license. This is less about driving and more about operating a tow business — it's a business regulation, not a driving requirement.
Before you start towing, contact your state's DMV and ask specifically: "What license do I need to tow commercially in this state?" Provide the weight of your truck and trailer so they can give you an accurate answer. Many DMVs have a commercial driver services section that can walk you through the exact steps.
Private Towing vs. Commercial Towing
If you're towing your own vehicle or equipment for personal use — moving a boat, trailer, or car you own — you generally don't need a CDL, even if you exceed the weight threshold. The CDL requirement kicks in when you're towing for hire or for business purposes.
However, this distinction is narrower than many people think. If you tow even occasionally for money — a side job helping a friend move a trailer, or one tow job for a neighbor — you may be considered to be operating commercially, which means you need a CDL. Some states are strict about this; others are more lenient. The safest approach is to assume you need a CDL if you're being paid, regardless of how often.
If you own a tow truck and operate it as a business, you almost certainly need a CDL. Even if you're the only driver and you only tow occasionally, the fact that the truck is registered as a commercial vehicle and you're using it to generate income usually triggers the requirement.
Medical Certification and Renewal
To get or renew a CDL, you must pass a Department of Transportation (DOT) medical exam. This is more thorough than a regular driver's license physical. The examiner checks your vision, hearing, blood pressure, and medical history. Certain conditions — uncontrolled diabetes, heart disease, sleep apnea, or certain medications — can disqualify you or require special certification.
Your Medical Certificate is valid for up to two years, but some conditions require annual renewal. Your CDL itself is valid for four or eight years depending on your state, but it's only valid if your Medical Certificate is current. If your Medical Certificate expires, your CDL is no longer valid for commercial driving, even if the license itself hasn't expired.
You'll need to renew your Medical Certificate before it expires. Many people miss this important date and find themselves unable to work until they pass a new exam. Mark the expiration date on your calendar and schedule your exam at least a month before it expires.
Frequently Asked Questions
Can I tow with a regular driver's license if I stay under 26,001 pounds?
Yes, in most states. If your truck and trailer combination stays under the federal threshold of 26,001 pounds GCWR, you can tow with a regular license. However, some states set their own lower thresholds, so check your state's DMV rules. Even if you're legal, your insurance may have different requirements.
What if I only tow occasionally or part-time?
If you're being paid to tow, even occasionally, you likely need a CDL. The frequency doesn't matter — it's whether you're towing for business or hire. Check with your state DMV to confirm, because this is where many operators get into trouble.
How long does it take to get a CDL?
The written test can be studied for in a few weeks. The skills test can be scheduled within days or weeks depending on your local DMV's availability. If you take a formal CDL training course, that typically takes two to four weeks. The entire process from start to finish usually takes one to three months.
Do I need a CDL if I own the tow truck but don't tow for money?
Not necessarily, if you're only towing your own vehicles or equipment for personal use and not being paid. However, if the truck is registered as a commercial vehicle, your insurance company may require a CDL regardless. Check with your insurance agent and your state DMV.
What happens if I tow without a CDL when I need one?
You can be cited for operating without the proper license, which typically results in a fine ranging from $100 to $1,000 depending on your state. Repeat violations can lead to license suspension. If you're in an accident, your insurance may deny the claim, leaving you personally liable for damages.
