What is the proper interval for following another vehicle to avoid accidents?

The proper interval for following another vehicle, which is indicated by the answer of spacing your vehicle at least 2 seconds behind the vehicle ahead, is rooted in ensuring a safe following distance to allow for adequate reaction times in case of sudden stops or emergencies.

The 2-second rule is a widely accepted guideline that helps drivers gauge a safe distance between their vehicle and the vehicle in front. By anticipating the time it takes to stop or react, this method accounts for variations in speed, road conditions, and vehicle performance. It's about creating a buffer zone that enhances safety, especially under adverse driving conditions such as rain or heavy traffic.

This method is effective because it allows a driver to focus not just on the vehicle directly in front of them, but also on their speed and the overall flow of traffic, adapting as necessary for safety. Other options, like a fixed distance in feet, do not account for variations in speed and road conditions that could lead to unsafe situations. Meanwhile, maintaining a close distance just to prevent others from cutting in is risky and does not promote safe driving practices.
