Explanation
The two-second rule means you should keep at least a two-second gap between your vehicle and the one ahead as a 'space cushion.' Having enough room in front of your vehicle allows you to stop safely if the vehicle in front brakes suddenly. In bad weather, poor road conditions, or when following large trucks, it’s best to increase your following distance.
