Correct answer

  • CSí, puede producirse el efecto pantalla y aproximarse de forma brusca al vehículo pesado.Yes, the screen effect can occur and the motorhome can suddenly move closer to the heavy vehicle.
Explanation

When you are side by side with a heavy vehicle in a strong crosswind, the screen effect occurs: the air pressure between the two changes suddenly, and the motorhome, which is tall and very sensitive to wind, can be pushed suddenly towards the lorry. You should hold the steering wheel firmly and increase the gap.
