When is passing not safe?

Answer: B — When approaching an intersection

Passing is not safe when approaching an intersection because at intersections, traffic patterns can change quickly and it can be difficult to predict the actions of other drivers who may be turning or merging. Passing at an intersection increases the risk of a collision or a near-miss. While passing on a straight road may seem safe, it is important to constantly assess traffic conditions and use caution before attempting to pass. Passing on a straight road can also become unsafe if there are other vehicles entering or exiting that road. Similarly, passing when other vehicles are going slower can be unsafe if there are other factors present, such as heavy traffic, poor weather conditions, or limited visibility.
