When can a driver pass on the right of another vehicle?

Passing on the right of another vehicle is permitted when the vehicle ahead is making a left turn. In this scenario, the left-turning vehicle creates a situation where the lane is clear for the driver to safely maneuver to the right to bypass the vehicle. This action is crucial for maintaining traffic flow and minimizing delays, especially at intersections where turning movements can frequently occur.

To ensure safety during this maneuver, a driver must confirm that there is enough space to pass without endangering the vehicle making the left turn, as well as other road users, including pedestrians and cyclists. Each state's traffic regulations may have specific rules regarding passing maneuvers, so it's essential for drivers to be aware of those laws in their area.
