When is it acceptable to pass a vehicle on the right?

Passing a vehicle on the right is acceptable when the vehicle ahead is turning left and the road is clear. This situation allows for the safe and effective passage of vehicles without endangering other road users. When the vehicle in front signals a left turn, it creates an opportunity for the driver behind to move into the right lane and continue forward instead of waiting for the left turn to be completed. It's essential that the road is clear and there are no obstructions or pedestrians in the way, ensuring that the maneuver can be executed safely.

In addition to this, it's important to acknowledge that while other scenarios may involve multiple lanes or different driving conditions, they do not meet the criteria for safely passing on the right. For example, passing on the right when going downhill or parallel to a pedestrian walkway may introduce hazards or restrictions that are not compliant with safe driving practices. Similarly, even with three lanes in one direction, the legality and safety of passing on the right depend on the context of the traffic and specific road markings. Hence, the correct practice revolves around the clear indication that a vehicle is turning left, which allows for a safe maneuver.
