In short, the odds are heavily in your favor that you are able to drive your RV with your standard drivers license.
However, some RVs are big. Like, really big. Bordering on the size of a semi, big. And because we’re a responsible society, we don’t just let anyone get behind the wheel of a very large vehicle without proving that they’re capable of driving it safely and responsibly—and proving you can turn a corner without taking out every lamp post on the sidewalk.
The Federal Motor Carrier Safety Administration sets basic guideposts for vehicles requiring a commercial driver’s license (CDL), but some states go stricter with their requirements. Some states require some kind of special licensing (not necessarily a CDL) if your rig is particularly large (usually in excess of 26,000 lbs., or heavier). Please note that this likely won’t apply to you unless you’re driving one monster of a Class A RV.
To reiterate, this won’t apply to the majority of RVs. But if you’re driving a particularly large Class A or doing additional towing, you’ll want to check your rig—and if you don’t know, your dealer or manufacturer should be able to provide you the information you need.
Some states also require that trailers be equipped with safety devices like equalizing hitches, sway control, and independent brake systems. Some heavier trailers may also require breakaway brakes.
