Where are the truck's blind spots most significant?

• A. In front of the cab
• B. Directly behind
• C. To the side and rear of the vehicle
• D. Under the trailer

Answer: (C)

Blind spots around a truck come from the size and shape of the vehicle and how mirrors cover (or don’t cover) the view. The areas that are most hidden from the driver are to the side and behind the truck. The trailer and cab block the driver’s line of sight laterally and rearward, so cars or pedestrians passing alongside or behind can be missed, especially during lane changes, turns, or sudden movements. That’s why you’re taught to avoid lingering in those zones and to pass with plenty of clearance and signal early. The area directly in front of the cab is generally more visible to the driver, and the space under the trailer isn’t the primary blind-spot concern in typical driving, so it’s not the best choice.
