When is it prohibited to pass a vehicle on the left at an intersection?

Answer: A — When the other vehicle is signaling left

Passing a vehicle on the left at an intersection is prohibited when the other vehicle is signaling left. This is because a left turn signal indicates that the driver intends to turn left, and passing on the left could lead to a collision if the turning vehicle makes its move. The rule promotes safety by ensuring that all drivers are aware of each other's intentions, especially at potentially dangerous locations like intersections where the likelihood of movements towards each other is increased. Intersections are critical points on the road where vehicles may be changing direction, and clarity of movement is crucial. By adhering to the signaling of other drivers, motorcyclists and other road users can navigate intersections more safely and reduce the risk of accidents.
