1. At speeds below 45 mph (70 km/h), maintain a following distance of at least two seconds. This can be estimated by using a visual cue, such as passing a fixed point on the side of the road (like a signpost or tree) and counting how many seconds it takes for the vehicle in front of you to reach the same point.
2. At speeds between 45 and 60 mph (70 to 100 km/h), maintain a following distance of at least three seconds.
3. At speeds above 60 mph (100 km/h), maintain a following distance of at least four seconds.
This distance can provide enough reaction time to respond safely to sudden stops, lane changes, and other unexpected maneuvers by the vehicle ahead. It also helps to reduce tailgating, which is dangerous and can lead to accidents.
Always adjust your following distance based on weather conditions, road conditions, and visibility. In low-light conditions, heavy rain, fog, or slippery surfaces, increase the following distance to provide additional reaction time.
