When is it legally permissible to pass another vehicle on the right?

Passing another vehicle on the right is legally permissible under specific circumstances that enhance safety and ensure traffic flow. When a vehicle is making a left turn, and there is a clear lane to the right, it is appropriate to pass on that side. This situation often arises in urban settings where multiple lanes allow for left-turning vehicles to signal their intent while other vehicles may continue to drive straight or pass on the right.

In this context, passing on the right when someone is turning left prevents traffic congestion and promotes smoother movement through an intersection. However, it is essential that the passing maneuver is performed in a clear lane, ensuring there are no obstacles or pedestrians that could pose a danger.

Other scenarios presented do not establish the same clear and safe conditions for passing. For instance, passing a parked vehicle can be hazardous due to the potential for doors opening or pedestrian movement. Speed limits or whether a street is one-way influence driving behavior but do not, on their own, justify passing on the right in a general sense. Hence, the specific situation of a left-turning vehicle with a clear lane on the right stands out as the correct basis for such a maneuver.
