What is the appropriate method to avoid rear-end crashes while driving?

Leaving plenty of space ahead is the most effective way to avoid rear-end crashes while driving. This practice, often referred to as maintaining a safe following distance, allows for adequate reaction time in case the vehicle in front suddenly stops or slows down. By ensuring there is ample room between your vehicle and the one ahead, you can better assess and respond to changing traffic conditions without the risk of colliding with the vehicle in front of you.

Maintaining a constant speed, while important for overall traffic flow, does not inherently prevent rear-end collisions, especially if the distance to the vehicle ahead is insufficient. Using cruise control may not always be advisable in varying traffic conditions since it can lead to reduced responsiveness during changes in speed. Additionally, driving in the left lane is not a guaranteed strategy to avoid rear-end crashes; instead, it can often lead to increased interactions with other vehicles, particularly if you are frequently changing lanes or passing.
