What effect does air turbulence have on smaller vehicles?

  1. Increases fuel efficiency

  2. Forces the vehicle off the road or draws it into the side of a large vehicle

  3. Improves the vehicle's aerodynamics

  4. Decreases the vehicle's speed

The correct answer is: Forces the vehicle off the road or draws it into the side of a large vehicle

Air turbulence has a negative effect on smaller vehicles by forcing them off the road or drawing them into the side of a large vehicle. This is due to the fact that smaller vehicles have less mass and are more susceptible to being pushed around by air turbulence. The other options are incorrect because air turbulence does not increase fuel efficiency, improve aerodynamics, or decrease speed for smaller vehicles.
