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

Aquaplaning occurs when a vehicle's tires lose contact with the road surface due to a layer of water, which can lead to a loss of steering control. The combination of factors that can contribute to aquaplaning includes:

1. **High speed**: Driving too fast for wet conditions reduces the time tires have to channel water away, increasing the risk of skidding.
2. **Worn tyres**: Tires with insufficient tread depth cannot effectively displace water, making them more susceptible to losing grip on wet surfaces.
3. **Grooves in the roadway**: While grooves can help with drainage, they can also trap water under the tire, which can cause aquaplaning if the vehicle's speed is too high or tires are worn.

Understanding these factors aligns with the German traffic regulations that emphasize safe driving practices under various road conditions. It is crucial for drivers to be aware of how their speed, tire condition, and road characteristics interact to maintain safety on wet roads.
