It is more like car length than seconds when following another car. You should be at least 2 car lengths from the other car.
A minimum of 2 seconds in good weather.
To determine your following distance in seconds, choose a fixed point on the road ahead, such as a sign or a tree. When the vehicle in front of you passes that point, start counting the seconds until you reach the same point. Divide the distance in feet between your vehicle and the one in front by 15 to convert to seconds. Ideally, you should aim for a following distance of at least 3 to 4 seconds for safety.
