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

Passing another vehicle on the right is acceptable when the vehicle in front is making a left turn. This is a common scenario on roadways, particularly when there are multiple lanes of traffic moving in the same direction. In such cases, if the left lane is occupied by a vehicle preparing to turn left, you may safely pass them on the right, provided there is room and it's legal to do so.

This maneuver should only be executed when it's clear and safe, as it helps in maintaining the flow of traffic without abrupt stops or delays. It's important that drivers are attentive to their surroundings and ensure that no other vehicles are obstructing the right side where the pass will take place.
