When following a large truck, you should be able to see the truck's mirrors in your rear-view mirror. If you cannot see them, you are likely:

• A. Too far behind
• B. Too close
• C. At a good following distance
• D. In the truck's blind spot

Answer: (B)

The important idea is keeping a safe following distance so you can see the lead truck in your own mirrors. If you can’t see the truck’s mirrors in your rear-view mirror, you’re too close. That small gap means less time to react if the truck brakes or stops, and you’re closer to the truck’s blind spots. Being too far behind or at a good following distance would still let you see the mirrors, so those options aren’t indicated by the situation. The risk of being in the truck’s blind spots is real, but the direct cue described here points to needing more space.
