You’re driving in a stream of traffic. What should you do if the vehicle behind is too close?

Explanation: It's dangerous for vehicles to travel too close together. Visibility is reduced and there's a higher risk of collision if a vehicle brakes suddenly to avoid a hazard. By increasing the separation distance between you and the vehicle in front, you have a greater safety margin. If necessary, this will allow you to reduce speed gradually and so avoid the vehicle behind being unable to stop within the space it has allowed.
