Louisiana requires a license plate on a tow dolly if it has a gross vehicle weight rating (GVWR) of 2,000 pounds or more

A tow dolly is a two-wheeled trailer that lifts the front wheels of a car off the ground so you can tow it behind another vehicle. In Louisiana, whether you need a license plate depends on the dolly's weight capacity, not how much weight you're actually carrying. If your dolly's GVWR—the maximum weight it can safely carry—is 2,000 pounds or higher, the state requires a license plate. If it's under 2,000 pounds, you do not need one.

The GVWR is printed on a label attached to the dolly's frame, usually near the hitch or on the tongue. Check this number before you tow anything. Many rental dollies fall below 2,000 pounds, but heavier-duty models and most purchased dollies exceed it. Louisiana treats this the same way it treats other trailers: weight determines registration status, not the type of cargo or how often you use it.

Key Takeaways

  • Check your tow dolly's GVWR on the manufacturer's label—if it is 2,000 pounds or more, Louisiana law requires a license plate.
  • The GVWR is the maximum safe weight capacity, not the actual weight you are towing, and it determines whether registration is required.
  • Dollies under 2,000 pounds GVWR do not need a license plate in Louisiana.
  • You can register a tow dolly at any Louisiana Office of Motor Vehicles by providing the VIN, GVWR documentation, and proof of ownership.
  • Towing without a required license plate can result in a traffic citation and fines.

How to find your tow dolly's GVWR

The GVWR is always printed on a metal or plastic label attached to the dolly's frame. On most dollies, this label is bolted to the tongue (the part that connects to your hitch) or to the main frame near the hitch connection. The label will list the GVWR in pounds and may also show the dry weight (the dolly's own weight without cargo).

If you are renting a dolly, ask the rental company for the GVWR before you leave. They should provide it in writing or on the rental agreement. If the label is missing or unreadable, do not guess—contact the manufacturer with the dolly's model number, or contact the rental company. A missing label is a safety issue and should be replaced before you tow.

Registering a tow dolly in Louisiana

If your dolly's GVWR is 2,000 pounds or more, you must register it with the Louisiana Office of Motor Vehicles. You will need the dolly's Vehicle Identification Number (VIN), which is stamped into the frame or printed on the manufacturer's label. You will also need proof of ownership—a bill of sale, purchase receipt, or manufacturer's certificate of origin.

Visit any Louisiana Office of Motor Vehicles location with these documents. The office will issue a license plate and registration certificate. The plate must be displayed on the rear of the dolly at all times while towing. Registration fees vary by weight and are paid at the time of registration. Once registered, your dolly's registration remains valid until you sell it or it is no longer in use.

What happens if you tow without a required license plate

Towing a dolly that requires registration without a license plate is a traffic violation in Louisiana. A law enforcement officer can stop you and issue a citation. The fine amount depends on the officer's jurisdiction and whether you have other violations, but it is typically in the range of $50 to $200 or more. You may also be ordered to stop towing until the dolly is registered.

Beyond the fine, towing an unregistered dolly can complicate insurance claims if you are involved in an accident. Your insurance company may deny a claim if the trailer was not registered as required by law. It is much simpler and cheaper to register the dolly upfront than to deal with a citation or insurance dispute later.

Rental dollies and temporary use

If you are renting a tow dolly for a one-time move or short-term use, the rental company is responsible for ensuring the dolly is registered if it requires registration. Ask the rental company whether the dolly is registered and whether the license plate is current. Most reputable rental companies maintain registration on all their equipment, but it is your responsibility to verify before you tow.

If you are renting a dolly under 2,000 pounds GVWR, no registration is needed, and you can tow it without a license plate. However, you should still inspect the dolly for safety—check the tires, lights, and hitch connection before you leave the rental lot. A damaged or unsafe dolly should not be used, regardless of registration status.

Difference between a tow dolly and a car trailer

A tow dolly lifts only the front wheels of a car off the ground, while a car trailer (also called a full trailer) carries all four wheels. Both require registration in Louisiana if they meet the 2,000-pound GVWR threshold. The same weight-based rule applies to both: check the GVWR label, and if it is 2,000 pounds or more, register it before you tow.

Car trailers are often heavier than tow dollies because they have a longer frame and more structural support. Most car trailers exceed 2,000 pounds GVWR and therefore require registration. Tow dollies are lighter but still often exceed the threshold, especially if they are designed for heavier vehicles. Do not assume a dolly is exempt just because it is smaller—always check the label.

Frequently Asked Questions

What if my tow dolly's label is missing or damaged?

Contact the manufacturer with your dolly's model number and year to request the GVWR. If you cannot reach the manufacturer, contact the Louisiana Office of Motor Vehicles—they can help you determine whether registration is required based on the dolly's specifications. Do not tow until you have confirmed the GVWR.

Can I use a tow dolly without a license plate if I only tow it a short distance?

No. If the GVWR is 2,000 pounds or more, Louisiana law requires a license plate regardless of distance. The law does not have an exception for short trips or private property. A citation can be issued even if you are towing just a few miles.

Do I need a separate driver's license endorsement to tow a dolly in Louisiana?

No. Louisiana does not require a special endorsement on your driver's license to tow a dolly, even if it is registered. However, you must follow all towing safety rules, including proper hitch connection, working lights, and find cargo.

What is the difference between GVWR and actual weight?

GVWR is the maximum safe weight the dolly can carry—it is set by the manufacturer and does not change. Actual weight is what you are towing right now. You can tow a light load on a high-GVWR dolly, but if the GVWR is 2,000 pounds or more, registration is required even if you are only towing 500 pounds.

How long does it take to register a tow dolly in Louisiana?

Registration is usually completed the same day you visit the Office of Motor Vehicles. Bring all required documents (VIN, proof of ownership, and the GVWR documentation), and the office will issue your license plate and registration certificate on the spot. Processing time is typically 15 to 30 minutes.
