In bad weather, when following a large vehicle, you should

• A. Increase your following distance
• B. Decrease following distance
• C. Wait to overtake
• D. Stop behind them

Answer: (A)

In bad weather, you should increase your following distance when behind a large vehicle. Wet or slick roads make stopping take longer, and heavy trucks need even more space to stop, start, or steer safely. Giving yourself extra room gives you time to react if the truck ahead suddenly brakes, helps you avoid spray or glare that can reduce visibility, and provides a cushion for unexpected hazards like debris or a lane change. In adverse conditions, aim for a longer gap than you’d normally keep—several seconds—to maintain a safe margin. Decreasing the distance, trying to overtake in poor weather, or stopping behind them all reduce your safety margin and can create dangerous situations for you and other drivers.
