Understanding the Left / Right Turn Prohibited Sign

Left / Right Turn Prohibited

Where: On any public road approaching a junction or intersection.

Purpose: To inform drivers that turning in the direction indicated by the sign (left or right) is not allowed at the upcoming intersection. This restriction is usually put in place to improve traffic flow, reduce congestion, or enhance safety where turning movements may be hazardous.

Action Required by Driver: Do not make a left or right turn at the intersection if the sign is displayed. Continue straight or follow alternative permitted routes.

  • Watch for detours — be alert for other signs or road markings that may indicate detours or directions for safe turning.
  • Signal early — if you plan to follow the permitted route, signal early to inform other road users.
  • Legal requirement — non-compliance may result in traffic fines or penalties, as it is a legal requirement to obey these signs.
