Maintaining a safe following distance is an essential defensive driving practice that gives drivers sufficient time to react when the vehicle ahead slows down or stops suddenly. Following another vehicle too closely, commonly known as tailgating, increases the risk of rear-end collisions, particularly in heavy traffic, at high speeds, and during sudden braking. Drivers should maintain an adequate gap based on their speed, road conditions, visibility, and vehicle braking performance. A practical guideline is to use at least a three-second gap in favourable conditions and increase it when roads are wet, visibility is poor, or traffic conditions are unpredictable.

To maintain a safe distance, drivers should choose a fixed roadside reference point and count the time between the vehicle ahead passing it and their own vehicle reaching the same point. If the gap is too short, they should gradually increase the distance without sudden braking. Heavy vehicles may require longer stopping distances, and drivers should allow extra space when travelling behind trucks, buses, or vehicles carrying heavy loads. Keeping a safe following distance improves reaction time, reduces collision risks, and makes driving safer for everyone on the road.
