What is the recommended minimum stopping distance for a car travelling at 100 km/h on a dry road?

The recommended minimum stopping distance for a car traveling at 100 km/h on a dry road is generally accepted to be around 70 metres. This distance takes into account both the reaction time of the driver and the braking distance required to come to a complete stop.

At higher speeds, such as 100 km/h, the distance a vehicle travels during the driver's reaction time becomes significant, in addition to the actual braking distance needed to decelerate the vehicle safely. On a dry road, with good tire traction, the braking distance is more manageable, but it still requires careful consideration of speed, road conditions, and vehicle performance.

Thus, the figure of 70 metres incorporates a safe buffer for emergencies, ensuring that drivers can stop in time to avoid collisions and respond effectively to obstacles or sudden changes in traffic. This serves to promote safety on the roads, aligning with best practices in driving and maintaining awareness of the vehicle's surroundings.
