What is the two-second rule used for?

The two-second rule is a guideline used to ensure safe following distances when driving. This rule suggests that a driver should allow at least two seconds of time between their vehicle and the vehicle in front of them. This time buffer provides adequate space to react to sudden stops or emergencies, which is crucial for avoiding rear-end collisions.

When following another vehicle, maintaining this two-second gap gives you enough time to assess your surroundings and react appropriately. If the vehicle ahead suddenly brakes or encounters an obstacle, having that two-second buffer allows for better stopping distance, enhancing overall road safety.

While other options mention various safety and operational aspects relevant to driving, they do not focus on the specific practice of maintaining sufficient distance between vehicles as the two-second rule explicitly does.
