When following a large vehicle with limited visibility, what should you do?

Answer: B — Stay back to increase view and reaction time

When you’re behind a large vehicle with limited visibility, the priority is to increase your following distance. Large trucks and buses have big blind spots and can’t see well to the sides or directly behind them. If you’re too close, you may not be seen and you won’t have enough time to react if they brake suddenly, stall, or encounter a hazard. By staying back, you gain a clearer view of the road ahead, you can see brake lights and signals sooner, and you have more time to react, which reduces the chance of a rear-end collision. In practice, give yourself extra space—often a four-second or greater separation is wise, especially in rain, fog, or at higher speeds. If you can’t see the truck driver’s face in their side mirrors, you’re likely in a blind spot and should wait to pass or adjust your position. Other choices would put you closer to the vehicle, keeping you in its blind spots or reducing your time to react, and stopping in intersections can block traffic and create danger for everyone.
