When driving on a multi-lane roadway, why is the right-side blind spot (No-Zone) of a large commercial truck significantly larger and more dangerous than its left-side blind spot?
- The driver sits on the left side of the cab, which greatly restricts direct visibility and mirror range along the right side of the vehicle.Answer
- BCommercial trucks are required to use flat mirrors on the right side that eliminate blind spots for passenger cars.
- CThe elevated position of the truck cab allows the driver clear sightlines to the right side, so blind spots only exist directly behind the trailer.
- DThe right-side blind spot only becomes active when the truck is executing a left-hand turn across traffic.
Answer
The driver sits on the left side of the cab, which greatly restricts direct visibility and mirror range along the right side of the vehicle.
Large commercial trucks have four major blind spots (No-Zones): front, rear, left side, and right side. Because the driver sits on the left side of the vehicle, viewing the right side relies entirely on mirrors across a wide cab distance. Consequently, the right-side blind spot is significantly larger than the left-side blind spot, reaching across multiple lanes.
