Towing laws can be confusing, and CDL requirements for trailers aren’t always clear. Many people assume they need a CDL to tow a big trailer, but that isn’t always the case.
Note: this post is not intended to serve as legal advice. It is instead meant to provide general information about towing Good Trailers or similar products, information that is based out of our expertise as trailer manufacturers. Always check your own state, local, and federal laws before you hit the road.
Determining whether you need a CDL will depend on a combination of your towing truck’s Gross Vehicle Weight Rating (GVWR) and your trailers’ GVWR.

What is a CDL?
A CDL (commercial driver’s license) is a special type of driver’s license required to operate heavy, large, or hazardous material vehicles. They are required for vehicles over 26,001 lbs., buses designed for 16+ people, or vehicles which haul hazardous materials.
Does “commercial” mean I only need a CDL if I am hauling for profit?
While it’s called a commercial drivers’ license, you may still need one even if you aren’t hauling equipment for commercial purposes. The weight of the vehicle is usually the deciding factor.
However, in some jurisdictions, agricultural exceptions do exist, especially if you are hauling heavy equipment between two pieces of land that you own. Check the regulations in your local jurisdiction before attempting a haul which might require a CDL.
Does a CDL apply to the actual weight of my load or only the rated capacity?
The CDL applies to the combined GVWR of the trailer and truck. It cares about what you could haul, not what you’re hauling. You should never load gear in excess of the trailer’s carrying capacity to begin with. The carrying capacity is equal to the trailer’s GVWR minus the weight of the trailer itself. The GVWR is the determining factor even if the trailer itself is empty.
Factors Which Could Change Requirements
Federal regulators generally exempt personal recreational vehicles (RVs) and horse trailers used for non-commercial purposes. Some local jurisdictions have agricultural exemptions as well.
If your truck and trailer combo exceeds 26,001 lbs., you should always check local and federal laws before you try to haul without a CDL. Some local jurisdictions also implement stricter laws, so check your state’s DMV website for details.
When in doubt, securing a drivers’ license upgrade is worth the peace of mind.
What to Check
Look for GVWR numbers in the following places:
- On the driver’s side door of your truck
- The VIN number sticker on the side of your trailer
On our website, you can also check the GVWR and carrying capacity specifications for each of our trailers on every product page.
Key Takeaways
CDL Requirements for trailers—the least you need to know:
- The Magic Number: Generally, you only need a CDL if the Gross Combined Weight Rating (GCWR) of your truck and trailer exceeds 26,001 lbs. GCWR = Trailer GVWR + Truck GVWR.
- Capacity over weight. Law enforcement looks at the rated capacity (GVWR) listed on your VIN plate, not how much the trailer actually weighs at the moment of the stop.
- “Commercial” is a misnomer. Even if you aren’t hauling for profit, you may still need a CDL if you exceed weight thresholds, though exceptions exist for RVs and some farm use.
- Where to look. Always verify your truck’s GVWR on the driver’s side door jamb and your trailer’s GVWR on the VIN sticker or manufacturer’s spec sheet.
- State vs. Federal. While federal law sets the baseline, state laws can vary. Always check your local DMV website for specific agricultural or personal use exemptions.
