DVSA theory test explanation

'Tailgating' is the term used when a driver or rider follows the vehicle in front too closely. It's dangerous because it restricts your view of the road ahead and leaves no safety margin if the vehicle in front needs to slow down or stop suddenly. Tailgating is often the underlying cause of rear-end collisions or multiple pile-ups.
