What spacing should you maintain when passing or being passed by a large vehicle with multiple trailers?

Answer: A — Maintain ample space to avoid gust effects.

When you’re passing or being passed by a large vehicle with multiple trailers, the air around it can create gusts and wind effects that push or yank your vehicle. Keeping ample space gives you room to react to those gusts and to safely complete the pass without the wind suddenly interfering. It also helps you stay out of the vehicle’s slipstream and away from its blind spots, reducing the risk of a loss of control or a collision. Moving closer, staying in the blind spot, or tailgating would increase your chances of being affected by the wind or by the other driver’s maneuvers, so they’re not safe options.
