What should you anticipate when you see this road sign?

This road sign warns you to be cautious of possible hazards caused by tree branches close to the road. According to German traffic rules, this sign indicates that branches might extend onto the roadway, which can cause unexpected obstacles. Because of this, you should expect:

1. Vehicles ahead that might swerve suddenly to the left to avoid obstacles like branches.
2. Vehicles ahead may need to brake suddenly for the same reason.
3. The presence of tree branches lying on the roadway itself.

All three points are correct because the warning covers not only the obstruction caused by branches but also the reactions of other drivers to these hazards. This means you should reduce your speed, stay alert, and maintain a safe distance to be able to react properly.
