When is it permissible to pass on the right?

Passing on the right is permissible when the vehicle being passed has signaled and is turning left. This situation is allowed because it provides a clear indication that the vehicle in front is about to make a left turn, allowing the driver to safely maneuver around it on the right side. This action ensures that traffic flow can continue efficiently while adhering to safety regulations.

In this context, passing on the right is not typically allowed in other scenarios such as when a vehicle is parked or when driving in a residential area, where street parking and other hazards may complicate the passing maneuver. On a one-way street, while it might be considered permissible in certain conditions, the specific circumstance of a left-turning vehicle signaling takes precedence, highlighting the intent for safety and clarity in driver actions.
