You want to overtake on a tree-lined avenue. What special aspect should you bear in mind?

The selected combination is correct because each choice highlights critical safety considerations when overtaking on a tree-lined avenue.

1. Misjudged side clearances: Drivers may struggle to gauge distances accurately due to the presence of trees. This can lead to dangerous situations during overtaking when space is tight.

2. Evasive maneuvers by high vehicles: Vehicles such as trucks or buses with tall superstructures may need to swerve to avoid branches, which can pose a risk to nearby vehicles during an overtaking maneuver.

3. Increased accident risk: Tree-lined avenues are associated with a higher frequency of accidents, especially when drivers do not account for the unique hazards that trees present.

According to German traffic regulations, drivers are required to ensure their safety and the safety of others before executing maneuvers like overtaking. A consideration of all these factors helps in minimizing risks and adhering to the principle of defensive driving.
