Under what conditions is it legal to pass another vehicle on the right?

Passing another vehicle on the right is considered legal in certain situations, and one of the main conditions is when the vehicle in front is making a left turn. This scenario allows the driver to safely pass on the right, as the left-turning vehicle is likely occupying the left lane, creating an opportunity for another vehicle to maneuver around it without violating traffic laws.

In contrast, options like driving on a one-way street or having a clear lane to the right may suggest legal passing opportunities, but they don't necessarily define the legality of the action as explicitly as the left turn scenario. Similarly, while construction zones may have specific rules, they often restrict some passing maneuvers. The key takeaway is that the act of passing on the right is primarily justified when another vehicle is preparing to turn left, as it indicates a safe and reasonable opportunity to proceed without obstruction.
