No U-Turn Signs
The purpose of the No U-Turn Sign (MUTCD R3-4) is to inform drivers that making U-turns is prohibited at a specific location, often due to limited visibility or unsafe conditions. This sign helps to maintain traffic flow and reduce the risk of accidents by preventing drivers from making potentially dangerous maneuvers.
