The best practice for preventing being hit from behind involves being aware of your surroundings, particularly the traffic behind you. Checking your rear-view mirrors allows you to see vehicles coming up behind you, which helps in assessing the distance and speed of those vehicles relative to your own. This knowledge enables you to make more informed decisions about your driving behavior, such as changing lanes or adjusting your speed, to avoid potential collisions.

While checking side mirrors can assist with lane changes and awareness of vehicles alongside you, and monitoring your speedometer is crucial for staying within speed limits, the rear-view mirror is specifically designed to give you a clear view of what is behind you. This is essential for preventing rear-end collisions, making checking your rear-view mirrors particularly critical in this context.
