What is the main cause of most rear-end crashes?

The main cause of most rear-end crashes is following too closely, which is often referred to as tailgating. When a driver does not maintain an adequate following distance, they have less time to react if the vehicle in front of them suddenly slows down or stops. This reduced reaction time increases the likelihood of a collision, as the driver may not be able to brake in time to avoid hitting the vehicle ahead.

Maintaining a safe following distance is crucial for safe driving, especially in varying traffic conditions and at different speeds. This practice not only allows for better visibility but also gives drivers sufficient time to respond appropriately to changes on the road, such as traffic lights, stop signs, or unexpected stops. By establishing and maintaining an appropriate distance between vehicles, drivers can significantly mitigate the risk of rear-end collisions.
