Louisiana trailer equipment rules
Breakaway switch
Every trailer or semitrailer of 3,000 lb gross weight or more must have brakes applicable by the towing driver from the cab, designed and connected so the brakes apply automatically in an accidental breakaway.

Safety chains
Safety chains, or a State Police-approved alternative device, are required on every trailer with a loaded gross weight capacity of up to 6,000 lb, securely attached to the towing vehicle and strong enough to hold the trailer if the connection detaches. The statute imposes no chain requirement above that weight.

How the 3,000 lb threshold applies to three trailers
Louisiana measures gross weight, so the weight of the trailer as loaded is what counts.
| Example trailer | Weight checked | Against 3,000 lb |
|---|---|---|
| Small utility trailer | 1,650 lb | Under the Louisiana threshold by 1,350 lb |
| Loaded just under the line | 2,900 lb | Inside the Louisiana limit, but one heavy load away from crossing it |
| Mid-size travel trailer | 4,800 lb | Over the Louisiana threshold by 1,800 lb — brakes required |
How Louisiana compares with neighbouring states
1 of the 3 states bordering Louisiana set a stricter brake threshold, so a trailer that is legal here may need brakes as soon as you cross the line. Equip for the strictest state on your route.
| Bordering state | Brake threshold | Compared with Louisiana |
|---|---|---|
| Arkansas | 3,000 lb gross weight | Same threshold |
| Mississippi | 2,000 lb gross weight | 1,000 lb stricter |
| Texas | 4,500 lb gross weight | 1,500 lb more permissive |
