Other State RV Regulations Explained
When travelling by RV or campervan in the United States, road and camping rules are not fully standardised nationwide. In addition to federal laws, each state (and sometimes counties or cities) sets its own regulations covering driving requirements, vehicle equipment, camping rules, and safety limits. For international travellers used to more consistent rules across European countries, this variation can be confusing.
This page explains how “other state” RV regulations work in practice, what often changes from state to state, and what generally stays the same. Knowing these differences helps you avoid fines, drive legally, and plan realistic daily distances. The guidance below focuses on common state-level variations you are likely to encounter when crossing state lines during a US RV holiday, but it is not a substitute for checking local rules.
Driving licences and age rules (state law vs rental policy)
In most US states, short-term visitors can legally drive an RV using their standard car driving licence from their home country, provided it is written in English or accompanied by an International Driving Permit (IDP). However, acceptance of foreign licences is governed by state law, while rental eligibility is set by the rental company.
- No special RV licence is required under state law for typical rental motorhomes and campervans.
- Minimum driver age and required driving experience are usually rental company policies (often 21 or 25), not statewide legal limits.
- Some states have additional licence classes or endorsements for very large or heavy private RVs, which generally do not apply to standard rental vehicles.
You can read more details in the driving licence FAQ.
Vehicle size, weight, and measurement differences by state
Most RV-related road regulations refer to length, height, and weight limits, which can vary by state and road type, especially for trailers and secondary highways.
- Measurements are expressed in feet, inches, and pounds, not metres or kilograms.
- Speed and distance are shown in miles and miles per hour.
- Fuel is sold in US gallons (1 US gallon = 3.78 litres).
For hired motorhomes and campervans, size limits are rarely an issue on interstate highways and major state roads. Restrictions are more common on narrow scenic byways, older tunnels, desert routes, or mountain passes, where posted height, length, or weight limits must be followed carefully.
Speed limits, signage, and driving culture
Speed limits are set by each state and posted on roadside signs.
- Limits are shown in miles per hour (mph) and can change when crossing state lines.
- RVs may have lower maximum speed limits than cars in some states, or on certain roads.
- Right turns at red traffic lights are permitted in many states after a full stop, unless a sign specifically prohibits it; rules and local enforcement can vary.
Compared with Europe, US highways are generally wider and designed for long distances, with fewer roundabouts and more multi-lane roads. Long driving days are common, but RVs accelerate slowly, require longer braking distances, and need disciplined lane use.
Camping rules that change from state to state
Camping regulations are one of the most variable aspects of RV travel in the US.
- State parks: Public parks managed by individual states. Reservation systems, fees, vehicle limits, and maximum stay lengths differ widely.
- Private campgrounds: Commercial RV parks with their own rules, pricing, and check-in requirements.
- Boondocking: Camping without hookups, typically on certain federal public lands where allowed. Rules differ between agencies, states, and local ranger districts.
- Full hookups: A campsite with electricity, fresh water, and a sewer connection.
- Dump station: A designated facility for emptying wastewater tanks, sometimes restricted to registered guests.
Some states permit overnight stays in highway rest areas under specific conditions, while others prohibit any overnight sleeping in vehicles. Regulations may also vary at county or city level, and enforcement is usually strict where overnighting is not permitted.
Insurance, enforcement, and roadside checks
Insurance coverage is arranged through your rental provider, but traffic enforcement practices and safety rules are primarily governed by state law.
- Police may stop RVs for equipment issues such as non-functioning lights, unsecured cargo, or missing licence plates.
- Seatbelt laws apply to drivers and front-seat passengers in all states, with rear-seat requirements varying by state and passenger age.
- Hands-free or mobile phone restrictions differ by state and are actively enforced.
It is advisable to carry your passport, driving licence, and rental agreement in the vehicle whenever you are driving.
Planning multi-state RV trips
Many US RV itineraries cross several states, for example starting in Los Angeles and travelling through the Southwest, or flying into Denver for Rocky Mountain routes.
When crossing state lines:
- Watch for immediate changes in speed limits, signage, and road conditions.
- Confirm campground booking rules and arrival policies in advance.
- Refuel regularly and plan water and waste tank stops, as facilities may be widely spaced in some states.
Key differences from Europe to remember
- No single nationwide camping system or pitch classification.
- Much longer distances; daily driving times often exceed typical European expectations.
- Greater variation in road rules, enforcement, and local restrictions between states.
Understanding how state-by-state RV regulations work makes multi-state US road trips far simpler and more relaxed. When you are ready, you can explore available campervans and motorhomes for your planned route on USARVRentals.com.
