What is the recommended minimum stopping distance for a car travelling at 50 km/h on a dry road?

The recommended minimum stopping distance for a car traveling at 50 km/h on a dry road is 25 metres. This distance accounts for the time it takes for a driver to perceive a hazard and react to it, as well as the distance covered while the vehicle is coming to a complete stop.

When driving at this speed, a typical reaction time of approximately 1 second is considered, during which the car continues to move forward. In addition, the braking distance, which depends on factors such as vehicle speed and road conditions, is also factored in to achieve safe stopping. At 50 km/h, the combination of reaction time and the braking distance results in a total stopping distance of around 25 metres on a dry road.

In contrast, distances that are shorter would not provide adequate stopping time, while those that are longer would exceed what is necessary for safe stopping under typical conditions.
