Ohio trailer laws and regulations
Ohio trailer rules from the BMV: 2,000 lb brake threshold, 4,000 lb title rule, 65 ft combo cap, 55 mph cap over 8,000 lb and the 2026 fee update.
In Ohio, the brake line is unusually low. Trailers with an empty weight of 2,000 lb or more, built on or after January 1, 1942, need brakes. Travel trailers and manufactured homes built on or after January 1, 2001 follow the same 2,000 lb empty-weight threshold. Any trailer required to have brakes also needs a breakaway.
Title kicks in at 4,000 lb. Below that, registration alone is the rule. Effective January 1, 2026, non-commercial trailer registration fees include a $16.00 administration and enforcement fee on top of the weight-based fee.

Registration and titles
All trailers on Ohio roads have to be registered with the BMV. Trailers over 4,000 lb also need a title. To register, bring proof of financial responsibility, lease docs if applicable, a valid Ohio driver’s licence and a weight slip (manufacturer’s certificate of origin or statement of origin) to your local deputy registrar.
Ohio offers a permanent registration for non-commercial trailers, which is a one-time fee instead of an annual renewal. Fees start around $16.25 for trailers under 2,000 lb, plus the new $16.00 administration and enforcement fee that took effect January 1, 2026.
General towing rules
Riding in a travel trailer or non-self-propelled manufactured home is prohibited. Riding in a pickup camper is allowed.
Dimensions
The trailer body maxes out at 40 ft. Tow vehicle plus trailer is capped at 65 ft. Width is 102 inches and height is 13 ft 6 in.
Hitches and chains
The drawbar or other connection between the tow vehicle and the trailer can’t exceed 15 ft. If the connection is a chain, rope or cable, you need a white flag or cloth at least 12 inches square displayed on it.
For any tow setup other than a commercial tractor or a fifth-wheel, stay chains or cables are required in addition to the drawbar. The trailer has to follow the tow vehicle’s path without veering.
Lighting rules
- Two red rear reflectors (can be part of the tail lamps or separate)
- At least one red tail lamp visible from 500 ft
- A white licence plate light visible from 50 ft
- Two stop lights visible from 500 ft
Speed limits while towing
Posted limits apply, with one important exception: vehicles over 8,000 lb can’t exceed 55 mph.
Mirror rules
The tow vehicle needs at least one rear-view mirror on the left side. Other mirrors aren’t mandated but are practical when a wide trailer blocks the side view.
Brake rules
Trailers with an empty weight of 2,000 lb or more, built on or after January 1, 1942, need brakes. Travel trailers and manufactured homes built on or after January 1, 2001 follow the same 2,000 lb empty-weight threshold. Any trailer required to have brakes also needs a breakaway system.
