Is It Legal to Make a U-Turn?
U-turns are often legal — unless a sign or local rule says otherwise. Here's how to tell when they're allowed.
It depends on where you are. U-turns are generally legal unless a sign prohibits them or local law restricts them — for example, at certain intersections, on some highways, near curves or crests where visibility is poor, or in business districts in some states. Always look for posted signs and check your state's rules.
Realizing you missed your turn, the instinct is to swing around. Whether that U-turn is legal depends heavily on where you are and what the signs say.
The general approach
In most states, U-turns are permitted unless prohibited by a posted sign or by a specific rule. That means the first thing to check is always the signage at the intersection.
Common restrictions
Even without a 'No U-Turn' sign, many states restrict U-turns where they're unsafe — on curves or hill crests where you can't see oncoming traffic, near railroad crossings, on some highways, and at intersections controlled in particular ways. A handful of states also limit U-turns in business districts. Because these rules differ, your state's driver handbook is the best reference.
Doing it safely
Where a U-turn is allowed, make it only from the proper lane, yield to oncoming traffic and pedestrians, and ensure you have clear visibility. If in doubt, going around the block is always legal.
This is general information about common U.S. rules and practice. Rules differ by state, city and country and change over time — confirm with an official source for your area before you rely on it.
