How can you legally pass another vehicle on the right?

Passing another vehicle on the right can be done legally under specific conditions. One primary situation where this is permitted is when the vehicle you are passing is making a left turn, and there is a clear and safe lane available for you to maneuver into. This allows you to proceed without interfering with the vehicle that is turning left, ensuring that your action is safe and lawful.

In addition to this context, it is crucial to recognize that there must be adequate space to complete the maneuver safely. This means checking for any obstacles, pedestrians, or other vehicles that could pose a risk. The rule is designed to facilitate smoother traffic flow and maintain safety on the road.

Other situations provided in the choices may not align with safe driving practices. For example, passing on a one-way street is generally acceptable; however, it's important to ensure that it does not compromise the safety of the traffic flow. Speeding is illegal regardless of the circumstances, and simply relying on another driver's signal does not justify passing on the right without ensuring the lane is clear and safe.
