What does the sign indicating "KEEP LEFT UNLESS OVERTAKING" mean?

• A. You must overtake on the left.
• B. You cannot overtake in the right lane.
• C. Drive in the right lane only when overtaking or in heavy traffic.
• D. You should always drive in the left lane.

Answer: (C)

The sign indicating "KEEP LEFT UNLESS OVERTAKING" means that drivers are advised to primarily use the left lane for travel, but they are permitted to move into the right lane to overtake slower vehicles. This sign is designed to promote smoother traffic flow and enhance safety by encouraging drivers to keep right only when necessary—specifically when they are passing another vehicle or if traffic conditions require them to do so, such as during heavy congestion. Adhering to this rule helps prevent unnecessary lane changes and minimizes the risks associated with overtaking, since it establishes clear expectations for all road users. By primarily using the left lane, drivers can reduce the likelihood of conflicts between vehicles traveling at different speeds and maintain a more orderly flow of traffic.
