You can typically haul one car on a trailer without needing a Commercial Driver's License (CDL) if you're driving for personal use. The critical factor isn't the number of cars but the total weight rating of your vehicle combination. If the Gross Vehicle Weight Rating (GVWR) of your truck plus the GVWR of your trailer is 26,001 pounds or less, and the trailer itself has a GVWR under 10,001 pounds, you generally won't need a CDL. However, if you're hauling for commercial purposes (e.g., for a business), the rules are much stricter and a CDL is almost always required.
The most common setup for non-CDL hauling is a heavy-duty pickup (like a F-350 or Ram 3500) towing an open or enclosed car trailer. The combined GVWR of this setup often falls just under the 26,001-pound threshold. It's not about the physical number of cars; a single, very heavy car on a heavy trailer could push you over the limit, while two lighter cars on a specific multi-car trailer might still be under.
You must also consider your state's driver's license requirements. Many states have a "Class A Non-Commercial" license for larger personal recreational vehicles or horse trailers that exceed standard license limits but don't require a full CDL. Always check your specific state's DMV regulations.
Key Data Points for Common Non-CDL Setups:
| Vehicle / Trailer Combination | Typical GVWR (Vehicle) | Typical GVWR (Trailer) | Combined GVWR | CDL Typically Required? |
|---|---|---|---|---|
| Half-Ton Truck + Single-Car Trailer | 7,000 lbs | 7,000 lbs | 14,000 lbs | No |
| 3/4-Ton Truck + Single-Car Trailer | 9,000 lbs | 10,000 lbs | 19,000 lbs | No |
| One-Ton Dually Truck + Enclosed Trailer | 14,000 lbs | 12,000 lbs | 26,000 lbs | No (At the limit) |
| One-Ton Dually + Larger Enclosed Trailer | 14,000 lbs | 14,000 lbs | 28,000 lbs | Yes |
| Medium-Duty Truck + Two-Car Trailer | 19,000 lbs | 12,000 lbs | 31,000 lbs | Yes |
Beyond licensing, ensure your truck is rated for the trailer's Gross Combined Weight Rating (GCWR) and that you have the correct hitch equipment. Safety is paramount, so practice driving and braking with a heavy load.

For most folks using a big pickup truck, the answer is one car. The government looks at the total possible weight of your rig—your truck plus the trailer. If that number is under 26,001 pounds, you're usually in the clear with a regular license. But this is for personal stuff, like moving your own project car. If you're getting paid to move it, that's a whole different ballgame with stricter rules. Always double-check your truck's doorjamb sticker and your trailer's VIN plate for the official weight ratings.

The law focuses on weight ratings, not the car count. You need to add the Gross Vehicle Weight Rating (GVWR) of your tow vehicle to the GVWR of your trailer. If that sum is 26,001 lbs. or more, a CDL is required. A standard car hauler trailer has a GVWR of about 10,000 lbs., so your truck's GVWR must be under 16,001 lbs. to stay under the CDL threshold. This typically limits you to a one-ton truck and a single-car trailer. Exceeding these limits, even for personal use, can result in significant fines.

I learned this the hard way when I started hauling cars for my restoration hobby. My F-250 and a 20-foot trailer were fine for one vehicle. The moment I considered a tandem-axle trailer big enough for two cars, I was looking at weights that required a special license. It’s not just about power; it’s about the weight caps. Your regular license covers you for a combined rating under 26k pounds. For two cars, you're almost certainly going to need a commercial license or a state-specific non-commercial Class A.

Check two numbers: the GVWR of your truck (on the doorjamb sticker) and the GVWR of the trailer (on its VIN plate). Add them. Is it over 26,000 pounds? If yes, you'll need a CDL for personal use, and definitely for any business activity. Most single-car haulers are designed to keep this total under the limit when paired with a heavy-duty pickup. The type of trailer matters, too; enclosed trailers are heavier than open ones. Your safest bet is to stick with a one-car setup unless you're prepared to get the proper commercial licensing.
