What is the three-second rule?

The three-second rule is a guideline used to measure following distance between your vehicle and the one in front of you. By ensuring that you maintain a distance that allows you to count three seconds of time from when the vehicle ahead passes a fixed point until your vehicle reaches the same point, it helps create a safe buffer zone. This time-based approach allows drivers to react to sudden stops or emergencies by providing adequate space to stop without rear-ending the vehicle ahead.

In congested traffic conditions or at higher speeds, maintaining this three-second following distance is particularly critical for ensuring safety on the road. It takes into account not just the speed of your vehicle, but also gives a margin of error for driver reaction time and stopping distance. This reinforces the importance of being aware and prepared for unexpected situations while driving.
