The sign indicates that a slow-moving vehicle is ahead; drivers should:

• A. Slow down and use caution
• B. Maintain speed and pass quickly
• C. Stop immediately
• D. Do not change speed

Answer: (B)

When you see a sign indicating a slow-moving vehicle ahead, the key idea is to adjust your speed and behavior to match the situation. Slow-moving vehicles—like tractors or road work equipment—travel well below normal highway speeds, so you need to reduce your speed and proceed with extra caution. Leave more space behind the vehicle and be prepared for sudden changes, such as the vehicle turning or stopping. You should only pass when you can do so safely and legally, with a clear oncoming lane and plenty of distance. Maintaining your current speed or trying to pass quickly creates a higher risk of a crash, while stopping immediately isn’t usually required unless there's a direct hazard. In short, ease off the throttle, slow down, and drive with heightened awareness until you can safely proceed.
