Where are you particularly at risk during an overtaking manoeuvre here?

You are correct in choosing both options 1 and 2 because they highlight important risks related to the truck's wind-sheltered area during overtaking.

When driving into the truck’s wind-sheltered area (option 1), you face the risk of sudden air turbulence caused by the large truck, which can affect your vehicle's stability and handling unexpectedly.

When driving out of the truck’s wind-sheltered area (option 2), the air pressure normalizes again quickly, which can cause a sudden change in vehicle behavior, like a strong gust pushing your car, requiring extra attention to maintain control.

The key rule is that overtaking near large trucks requires caution because the air turbulence created by their size can affect your vehicle’s stability both when entering and leaving the wind-sheltered zone beside the truck. This is why both points 1 and 2 represent critical risk moments during overtaking maneuvers.
