When is it legal to pass another vehicle on the right?

It is legal to pass another vehicle on the right when that vehicle is making a left turn. This scenario is permissible because the vehicle that is turning left is temporarily occupying the lane to the left, allowing other vehicles in the same lane or a lane to the right to continue moving without obstruction. Driving on the right in this circumstance allows for better traffic flow and reduces delays caused by the left-turning vehicle.

In contrast, passing on a one-way street is generally acceptable as long as it is safe and does not conflict with traffic laws, but it must still be done with caution and awareness of other vehicles. Passing when the road is clear and there are no markings might suggest an unregulated situation, which can lead to dangerous actions, as there may be specific rules governing that area. Simply feeling that it is safe does not follow legal guidelines; safety is paramount, but it must align with the traffic laws in effect. Therefore, the context of vehicles turning and lane usage is crucial when determining the legality of passing on the right.
