Why are rear-end crashes common on highways?

1. Because drivers follow too closely

2. Because drivers stop abruptly

3. Because road conditions are poor

4. Because of distracted driving

The correct answer is: Because drivers follow too closely

Rear-end crashes are common on highways primarily because drivers tend to follow too closely behind the vehicle in front of them, a behavior known as tailgating. When drivers maintain an insufficient following distance, they have less time to react to the actions of the vehicle ahead. If that vehicle slows down or stops suddenly and the following driver is too close, there is a higher likelihood of a collision, as the trailing driver may not have adequate time or space to brake safely. Maintaining a proper following distance not only gives drivers more time to react to abrupt changes in traffic flow but also helps to prevent the chain reaction crashes that often occur during sudden stops. Being aware of safe following distances based on speed limits, type of vehicle, and traffic conditions is crucial for reducing the risk of rear-end collisions.
