You are driving outside built-up areas. Visibility is reduced to just about 50 m due to heavy rain. What applies in this situation?

When driving outside built-up areas in conditions of reduced visibility, specific German traffic regulations come into play to ensure safety.

1. Overtaking is prohibited for motor vehicles with a permissible total mass exceeding 7.5 t. This rule is in place to prevent accidents in poor visibility. Heavy vehicles require more time and space to maneuver, making overtaking dangerous in such conditions.

2. The maximum permissible speed is 50 km/h in reduced visibility. This speed limit is designed to give drivers enough time to react to hazards that may not be easily seen due to the weather conditions.

It's important to adhere to both rules because they are intended to increase road safety and reduce the likelihood of accidents in challenging weather conditions. If you had included the third choice regarding the rear fog lamp, it would also have been relevant, as using fog lamps is necessary in low visibility to ensure that other drivers can see you clearly.
