What must you anticipate with this road sign?

This road sign indicates a potential hazard related to trees and roadside vegetation. It alerts drivers to anticipate that:

1. **Trees could protrude into the roadway**: This means that branches or entire trees might intrude into the area designated for vehicles, requiring cautious navigation.

2. **There could be branches lying on the roadway**: Fallen branches can pose a risk, particularly in windy or stormy weather, which can affect driving conditions.

3. **Vehicles could swerve suddenly**: Another aspect to consider is that drivers may need to maneuver away from obstacles or hazards, which could lead to erratic driving behavior in their vicinity.

Understanding these points is crucial for maintaining safety on the road and is a key aspect of German traffic regulations, which emphasize being prepared for unexpected conditions that could impact road use. Always remain vigilant in these areas to ensure safe driving practices.
