Recreational vehicles (RVs) come in many different shapes and sizes: A small pop-up camper, a shell on a pickup truck, and a large motor home are all considered RVs. Most traffic laws that apply to other cars on the road also apply to RVs. But certain rules apply specifically to RVs.

Lane Usage Drivers must stay in the right lane when driving an RV except when passing, preparing to make a turn, or going on or off the highway. If the highway has four or more lanes in either direction, you must stay in either of the extreme right lanes.

Trailer Lights When your RV includes a trailer, it is important to keep in mind that the trailer's weight often forces the RV's headlights upward so that they glare into the eyes of oncoming drivers. This is illegal; you must check your headlight alignment once the trailer is attached.

Parking Checking with any neighborhood associations or cities where you plan to stop, to see if they have any rules or ordinances against parking RVs. Many residential neighborhood homeowner associations will let RVs be parked for short periods of time, but not overnight.
