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

The recommended minimum stopping distance for a car traveling at 50 km/h on a wet road is correctly noted as 36 metres. This distance takes into account the reduced friction between the tires and the road surface due to wet conditions, which significantly impacts braking performance.

At this speed, when the road is wet, the car requires a longer distance to stop compared to dry conditions because of hydroplaning and reduced traction. The stopping distance is calculated based on both the driver's reaction time and the braking distance. In wet conditions, the average driver requires about one second more for perception and reaction, which when factored in leads to the 36-metre guideline for stopping effectively.

Understanding this distance is crucial for safe driving practices, particularly in maintaining appropriate following distances to ensure enough time to react to potential hazards while driving in less-than-ideal weather circumstances.
