What can be caused if the road surface suddenly becomes worse?

The correct combination of dangers that can arise when the road surface becomes worse includes both sliding and skidding risks, as well as changes in tyre noise.

When the road conditions deteriorate, such as when it becomes wet, icy, or covered in debris, the friction between the tyres and the road surface decreases, increasing the risk of sliding or skidding. This is a significant safety hazard and is emphasized in German traffic laws to ensure drivers remain vigilant under changing conditions.

Additionally, changes in tyre noise can indicate that the grip on the road is compromised, alerting drivers to the need for caution. This aspect is also important in understanding vehicle dynamics and maintaining control.

Understanding both points helps drivers to assess and react appropriately to changing road conditions, enhancing overall safety on the road.
