Visibility is considerably reduced. When are you allowed to switch on fog headlamps?

In Germany, using fog headlamps is specifically regulated to enhance safety in low visibility conditions. The selected combination of visibility factors—rain, falling snow, and fog—are all situations where standard headlights may not provide sufficient illumination. Each condition can severely reduce visibility, making fog headlamps appropriate.

1. In rain: Heavy rain can create a reflection that blurs visibility. Fog headlamps, which are designed to cast light lower to the ground, can help illuminate the road surface better in such conditions.

2. In falling snow: Similar to rain, falling snow can obstruct visibility. Fog headlamps help by illuminating the area directly in front of the vehicle without reflecting off the snowflakes.

3. In fog: This is the primary condition for using fog headlamps, as they are specifically designed to cut through fog and increase visibility without causing glare.

Selecting all three conditions is crucial as they each present unique challenges that can be mitigated by using fog headlamps, according to German traffic regulations. Using them appropriately increases safety for yourself and others on the road.
