Which of the following is an acceptable situation in which a driver can pass on the right?

Passing on the right is legally permitted in certain situations to enhance road safety and traffic flow. One of the most common scenarios in which a driver can pass on the right is when another vehicle is turning left. In this case, the vehicle making a left turn is occupying the left lane, allowing drivers in other lanes, specifically the right lane, to safely maneuver around the turning vehicle. This not only adheres to road rules but also helps avoid unnecessary delays and maintains the flow of traffic.

While it's essential to be aware of the surrounding conditions, such as road and vehicle positions, passing on the right in situations involving a left-turning vehicle is a recognized and intentional aspect of traffic regulations. This regulation is designed to accommodate multiple movements on the road while ensuring that drivers can continue to move efficiently without conflicts.
