Regulatory Signs

Understanding the Proceed Left / Right / Straight Only Sign

Proceed Left / Right / Straight Only

Where: At intersections or junctions where traffic movement is restricted to a specific direction. Often used on one-way streets, divided roads, or lanes leading to different routes.

Purpose: To inform drivers of the permitted direction of travel at the intersection. It ensures safe and orderly flow of traffic by preventing vehicles from turning or proceeding in prohibited directions, reducing the risk of collisions and traffic conflicts.

Action Required by Driver: Drive only in the direction indicated by the arrow on the sign (left, right, or straight), and do not turn or deviate from the indicated direction.

  • Signal early — indicate in advance to inform other road users of your intended movement.
  • Check before proceeding — look for pedestrians, cyclists, and other vehicles before proceeding, even when following the sign.
