No U-Turn Signs

On your own property the sign states your rule, and enforcement is up to you, your lease or your HOA. Public roads are different, since only the city or state sets official traffic signs there. Check your local rules before you post one near a road.

Put it at the lot exit or where a driver might turn around, at eye height and facing the car. An 18 x 12 in landscape sign reads from the driver's seat. Reflective aluminum shows at night in 18 x 12 in, 24 x 18 in or 12 x 18 in.

Red on white is the traditional prohibition look and reads as a rule from a distance. Black on white is plainer and fits a business or HOA with a quieter style. Both come in aluminum or plastic.

A direction helps most, such as Right turn only or Exit this way, since the sign then tells a driver what to do instead. Keep the words short so the sign reads at speed. If you want a note about towing, check your state and local rules first, since those rules depend on where you are.

A sign at the exit works before the turn, and a driver who has already turned needs a sign ahead of the next turn. Two signs on a long drive can catch drivers who miss the first one. Walk the lot at a busy time to see where cars try to turn, and place the second sign there.
