Outside a built-up area, a motorhome is going to overtake a heavy vehicle. Can a risk situation arise when they travel in parallel if a strong lateral wind is blowing from the left?
A)No, if both vehicles have the same volume and weight.
B)Yes, because a sudden push of both vehicles toward the left would occur.
C)Yes, the screen effect may occur and it may suddenly move closer to the heavy vehicle.Correct
# Explanation: Screen Effect in Overtaking
When a motorhome overtakes a heavy vehicle with a strong lateral wind from the left, the **screen effect** occurs. The heavy vehicle acts as a barrier that blocks the wind, creating a protected zone alongside it. When passing through this zone, the motorhome experiences a sudden change in air pressure that involuntarily brings it closer to the heavy vehicle, generating a risk of collision.
