When is it acceptable to pass on the right of another vehicle?

Passing on the right of another vehicle is acceptable when the vehicle is about to make a left turn. This situation indicates that the vehicle is preparing to move left across its lane, potentially causing a hazard for vehicles following behind it. By passing on the right, a driver can safely maneuver around the turning vehicle, provided that there is enough space and it is legal to do so based on road conditions and traffic rules.

In various contexts, other scenarios such as construction zones or narrow roads may restrict or complicate passing maneuvers due to the presence of workers, equipment, or limited space. Similarly, in residential areas, conditions may vary with parked cars, pedestrians, and children playing, making passing on the right less safe or advisable.
