What must you anticipate with this road sign?

This road sign indicates potential hazards related to overhanging trees and tree branches near the roadway. It's essential to anticipate the following:

1. Trees could protrude into the road area: This is crucial because drivers need to be cautious of their vehicle's height and width, especially in relation to larger vehicles like trucks.

2. There could be branches lying on the roadway: Fallen branches can pose obstacles, leading to dangerous situations for drivers who may not expect them.

3. Vehicles could swerve suddenly: Other drivers might react unpredictably to obstacles such as low branches, which can lead to unsafe maneuvers.

Understanding these points helps ensure safety while navigating areas where such environmental features exist, in line with German traffic regulations.
