What should you maintain while driving?

Maintaining a safe following distance is essential for safe driving. This distance allows for adequate reaction time in case the vehicle in front of you suddenly stops or slows down. A safe following distance helps prevent rear-end collisions and gives you the opportunity to react to unexpected changes in traffic conditions, such as sudden stops or emergencies. It is typically recommended to follow the "three-second rule," which suggests that you should be at least three seconds behind the vehicle in front of you to ensure you have enough time to stop safely.

While a steady speed, proper lane position, and full attention are also critical aspects of driving, they do not directly address the immediate risks associated with proximity to other vehicles. Steady speed is important for maintaining traffic flow, and correct lane positioning helps ensure safe navigation within lanes, but these factors do not compensate for a lack of distance between vehicles. Distraction from using a phone significantly increases risk and is contrary to the focus required for safe driving. Hence, maintaining a safe following distance is the most crucial action among the options listed.
