In which of the following situations does fast driving often lead to accidents?

Fast driving can significantly increase the risk of accidents in several critical situations. When approaching pedestrian crossings, driving at high speeds limits a driver's ability to react to pedestrians who may suddenly step into the road. It also reduces the time available for the driver to assess the situation and stop safely.

At intersections and junctions, fast driving impairs a driver's ability to scan for other vehicles and pedestrians. This can lead to collisions if a driver fails to notice a vehicle that has entered the intersection or a pedestrian crossing the road.

Restricted vision points, such as curves or hills, present a unique challenge; fast driving in these areas can prevent a driver from seeing hazards in time to respond appropriately. The lack of visibility increases the likelihood of accidents as the driver may encounter unexpected obstacles or other vehicles.

Given that fast driving can lead to accidents in all these conditions, the most comprehensive answer is that all situations mentioned contribute to the increased risk of accidents when driving at high speeds. This highlights the importance of adjusting speed according to road conditions and environmental factors to ensure safety.
