When is it considered legal to pass a vehicle on the right?

Passing a vehicle on the right is considered legal in specific situations, and one of those situations is when the vehicle is making a left turn. In this case, the driver intending to pass is effectively maneuvering around a vehicle that is slowing down or stopped to make a left turn. This action is permissible as long as it is safe and there is enough space to do so without endangering oneself or other road users.

In contrast, passing on the right might not be legal in other scenarios, such as on roads with only one lane in each direction, where the passing lane is typically only on the left. Therefore, understanding the context of vehicle behavior, traffic laws, and road layouts is crucial in determining when passing on the right is appropriate.
