Defensive driving

The two-second rule tells a defensive driver the minimum distance to avoid collision in ideal driving conditions. The red car's driver picks a tree to judge a two-second safety buffer.

Defensive driving describes the practice of anticipating dangerous situations, despite adverse conditions or the mistakes of others when operating a motor vehicle. It can be achieved by adhering to general guidelines, such as keeping a two- or three-second gap between the driver's vehicle and the vehicle in front to ensure adequate space to stop. It is a form of training for drivers that goes beyond road rules and the basic mechanics of driving techniques. Defensive driving reduces the risk of collisions and improves road safety.
