What does a safe distance you should keep while driving behind another car depend on?

A safe following distance from the vehicle ahead depends primarily on the speed at which you are travelling. The higher the speed, the longer the braking distance, so you need more space to stop safely. According to Art. 19 para. 2 pt. 3 of the Road Traffic Act, you must maintain the distance necessary to avoid a collision. You should also consider other factors such as weather conditions, the road surface, and your reaction time.
