While driving, it suddenly begins to rain heavily. What should you do?

The selected combination of reducing speed and avoiding strong acceleration is essential when it begins to rain heavily. This aligns with the principles of safe driving according to German traffic regulations. Reducing speed is crucial because wet roads can lead to decreased traction, increasing the risk of skidding or losing control. Similarly, avoiding strong acceleration prevents sudden changes in vehicle dynamics that can compromise stability and control.

Maintaining a longer safety distance is also important in these conditions, but your answer did not include it. By ensuring a greater distance from the vehicle ahead, you have more time to react to potential hazards, which is vital during adverse weather conditions. In summary, for safe driving in heavy rain, it is important to reduce speed, avoid rapid acceleration, and maintain an appropriate safety distance. All these measures collectively enhance safety on the road.
