A no U-turn sign is a traffic sign that prohibits drivers from making a U-turn at a specific intersection or area. The sign is usually displayed to prevent unsafe or disruptive turns that could lead to accidents or cause traffic delays. The sign typically features a red circle with a line crossing through an arrow pointing in a U-shape. Drivers must find an alternative route or wait for a designated area where U-turns are allowed to avoid a violation and ensure the flow of traffic remains smooth.
