What can cause in aquaplaning (sliding on wet roads) on wet road surfaces?

The combination of high speed, worn tyres, and grooves in the roadway contributes significantly to aquaplaning on wet surfaces.

High speed reduces the time that water has to drain away from the contact area of the tire, increasing the risk of losing traction. Worn tyres have less tread depth, which is essential for channeling water away and maintaining grip on wet surfaces. Grooves in the roadway, while designed to improve drainage, can also create conditions that lead to aquaplaning if water accumulation exceeds the drainage capability.

According to German traffic regulations, drivers must ensure their vehicles are equipped with appropriate tyres that are not worn, and they must adjust their speed to the conditions, especially in wet weather. Understanding these factors helps improve safety and minimizes the risk of accidents due to aquaplaning.
