Recreational vehicles come with a variety of RV rules, regulations, and road restrictions. From bridge height clearances to allowable cargo weights, it’s important to know where you’re going and what kinds of road restrictions to be prepared for along the way.
It’s not feasible to document every single state rule, regulation, and road restriction for RVs here. Instead, this post will help guide you in what to research so you, your passengers, and your RV travel safely.
(This post is NOT intended as legal advice—be sure to check the most up-to-date local, state, and national rules and regulations before heading out on the road!)
RV Road Restrictions for Length, Width, and Height
Traveling across the country can get tricky because rules and regulations vary by state. The length of your trailer or RV, for example, can go from legal to illegal, just by passing over an imaginary line in the road.
Remember that RV length is different than trailer length. An RV is a drivable recreational vehicle and a trailer is anything towed behind a vehicle with an engine, which can include travel trailers, fifth wheels, toads, boat trailers, and more.
