A safe following distance depends on your speed, driving conditions and the type of vehicle you are driving. In good conditions, you should drive at least two seconds behind the vehicle in front of you.
To determine the two seconds – watch the vehicle in front as it passes a landmark, such as a tree, sign, power pole or overpass. As it passes the landmark, start counting ‘one thousand and one, one thousand and two’ (this takes about two seconds). If you pass the same landmark before you finish counting to two seconds, you’re too close.
It is important to increase your following distance if the weather or road conditions are poor, if you’re driving a heavy vehicle or towing a trailer.
Fog lights can be used in foggy conditions, dust storms or heavy rain. But do not drive with both headlights and fog lights on at the same time.
