Registration and title
Trailers operated on Virginia highways need both a title and a registration. The Virginia DMV handles both. Trailers under 4,000 lbs are eligible for full-size or small-size license plates, depending on whether the trailer has room to mount the larger plate.
Annual or biennial renewal fees apply. Let your registration lapse and you face penalties when re-registering.
Dimensions
- Max combined length (vehicle plus trailer, with bumpers): 65 ft.
- Max trailer length: 45 ft.
- Max trailer width: 102 in.
- Max trailer height including load: 13 ft 6 in.
Loads over these limits need an oversize permit from VDOT.
Riding inside a house trailer while it is being towed is prohibited.
Hitch and safety chains
Virginia requires safety chains or cables as a secondary connection in addition to the primary hitch or coupler. These backup attachments must be present on every trailer regardless of weight.
The general principle: if the primary hitch fails, the safety chains must keep the trailer attached and prevent the tongue from hitting the pavement.
Lighting
Virginia trailer lighting requirements:
- Red lighting at the back of the trailer, visible from 500 ft in clear weather.
- A separate white light illuminating the rear license plate, visible from 50 ft.
- Reflectors at the rear of the trailer facing backward.
- Tail lights, brake lights, and turn signals as standard.
If you tow with a 2021 to 2026 Ford F-150, 2022 to 2026 Super Duty, Ranger, Expedition, Maverick, Transit, or Lincoln Navigator, check recall 26C10 (NHTSA 26V104000). Ford pushed an OTA fix in March 2026 for an Integrated Trailer Module software fault that affects trailer lights and brake function.
Speed limits
No special trailer speed in Virginia general traffic. Posted limits apply. Officers can stop drivers for unsafe operation (trailer swaying, weaving) even when under the posted limit.
Mirrors
Virginia requires mirrors that give an unobstructed view of the road behind the vehicle for at least 200 ft. Specifically:
- At least one mirror outside of the tow vehicle, plus one inside.
- If internal mirrors are obstructed by the trailer or load, exterior mirrors on both sides of the tow vehicle are required, and they must be visible from the driver’s seat.
Tow mirror extenders (clip-on or replacement) are the typical fix for trailers wider than the tow vehicle.
Brakes
Virginia keeps the brake rule simple: if a trailer’s gross weight exceeds 3,000 lbs, it must be equipped with brakes.
The state does not spell out specific stopping distance or auto-engagement language the way some neighbors do, but the general expectation is:
- Brakes operable from the tow vehicle’s cab (electric brake controller).
- A working breakaway switch that applies trailer brakes if the trailer separates.
A Tekonsha P3, Redarc Tow-Pro Elite, Curt Echo, or factory-integrated brake controller all satisfy the cab-control requirement. Breakaway switches and batteries should be tested before each trip by pulling the pin with the trailer chocked and confirming the brakes apply.
