What can be the causes of rear-end collisions?

Your answer was correct as it included all the significant factors that contribute to rear-end collisions.

1. Unexpectedly heavy braking often occurs when drivers need to stop suddenly due to obstacles or traffic conditions, leading to a higher risk of a collision from behind.

2. Inattentiveness can cause drivers to fail to notice slowing traffic or changes in the road situation, making it more likely for them to rear-end another vehicle.

3. Driving too close behind another vehicle reduces reaction time in emergencies; if the front vehicle stops, the driver behind may not have sufficient time to react, resulting in a collision.

In German traffic regulations, maintaining a safe following distance and being attentive are critical aspects of road safety. According to the German Road Traffic Regulations (StVO), drivers must ensure they can stop safely at all times, which includes accounting for the behavior of the vehicle in front. Understanding these contributing factors is essential in preventing rear-end collisions.
