Unit 2 sec 2.1

A common cause of road accidents is drivers failing to leave an adequate gap between their vehicle and the one in front. The Highway code includes recommendations for these gaps. Different speeds and in a variety of weather conditions. These are divided from two different mathematical models.
Stopping distances
Drive at a speed that will allow you to stop well within the distance you can see to be clear. You should
v Leave enough space between you and the car in front of you so that you can pull up safely if suddenly slows down or stops - this save rule is never to get closer than the overall stopping distance.
v Allow at least a two second gap between you and the vehicle in front on roads carrying faster moving traffic and in tunnels where visibility is reduced - the gap should be latest doubled on wet roads and increased still further on icy roads.

The highway code stresses that the driver should ensure that they can stop the car safely, whatever the road conditions. The guidance on the distances and times that the driver should allow between the vehicle and the one in front.
v The distance model suggests that his safe distance between your vehicle and the one in front is the distance given by the typical stopping distance chart. This stopping distances are presented both as a chart and as numerical measurements.

v The time model suggests that a safe distance between your vehicle and the one in front is the distance given by the two second rule.
