When can you use the shoulder of the road to pass another vehicle?

Using the shoulder of the road to pass another vehicle is not permitted under any circumstances, as it can create a dangerous situation for both the driver and other road users. Shoulders are designed for emergency parking, breakdowns, or situations where a vehicle needs to pull off the road, not for regular driving maneuvers such as passing.

If a driver uses the shoulder to pass another vehicle, they may not anticipate oncoming traffic, pedestrians, or obstacles that could pose a risk. Additionally, it can lead to confusion for other drivers who may not expect a vehicle to be on the shoulder, thus increasing the risk of collisions. Safety on the road is a priority, and adhering to traffic laws prevents dangerous situations that can arise from improper use of roadways.

The other choices may imply scenarios where one might consider using the shoulder, but none of those provide a valid or safe justification for such action.
