This test demonstrates the distance required to stop a car travelling at 40 kph and at 70kph when the brakes are applied suddenly, simulating an emergency stop.
The students are asked to predict the stopping point by placing a cone alongside the test run and once they are safely behind the barrier the test begins. Students are genuinely astonished at the distance required to bring the car to a halt and invariably it is at least 20 metres further than their estimate.
The students discuss the results with the tutor who explains the various factors that influence stopping distances of a car and asks them to consider the results from three different perspectives;
a) As pedestrians crossing the road.
b) As cyclists who share the road with motorists.
c) As motorists when they begin driving.
