During what situation is it permissible to pass another vehicle on the right?

Passing another vehicle on the right is permissible in specific circumstances, and both situations presented are valid.

When a vehicle is making a left turn, it creates an opportunity for other vehicles to pass on the right. In this situation, the left-turning vehicle is moving to the left side of the road, which may create space on the right for another vehicle to safely go around it. This is a common scenario in areas where traffic regulations allow for this maneuver.

Additionally, when driving on a one-way road, all traffic is moving in the same direction. Therefore, passing on the right is not only permissible but also often necessary, as there may not be a left lane available for passing. On one-way streets, vehicles can utilize both lanes without the risk of conflicting directions.

Together, these scenarios encapsulate the situations in which passing on the right is allowed, showcasing the importance of context in understanding traffic rules.
