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

Passing another vehicle on the right is legal in specific situations that enhance safety and traffic flow. One such situation is when the vehicle being passed is making a left turn. In this case, the lane to the left of the turning vehicle is temporarily blocked, allowing you to maneuver to the right and pass safely.

Additionally, passing on the right is permitted on a one-way street where multiple lanes are available. In such scenarios, drivers are expected to keep left unless they are overtaking someone traveling at a slower speed or making a left turn.

The other options do not capture the conditions under which passing on the right is allowed. Heavy traffic does not give any specific legal right to pass on the right, and merely moving slowly is not the legal basis for passing. Additionally, there are circumstances where passing on the right is permitted, so it's incorrect to claim that it is never legal. Being aware of these regulations is critical for safe driving practices and adhering to traffic laws.
