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

The situation in which it is permissible to pass another vehicle on the right is specifically when that vehicle is making a left turn. This practice is allowed because the vehicle turning left is moving into the opposing lane, effectively creating an opening on the right side for another vehicle to safely pass. Additionally, it reflects a recognition of the typical flow of traffic, as vehicles are generally traveling in their designated lanes, and passing on the right helps to maintain that flow.

Passing on the right under other circumstances may not adhere to safe driving practices. For instance, passing on the shoulder is dangerous and could lead to accidents, as the shoulder is not designed for regular traffic maneuvers. Moreover, passing when there is no clear, legal, and safe opportunity increases the risk of collisions, which is why proper knowledge and adherence to the rules concerning passing are crucial for maintaining safety on the road. This emphasizes the importance of being aware of other vehicles' actions and understanding the regulations associated with passing to ensure that all maneuvers are conducted safely and legally.
