While driving on a multi-lane highway, you prepare to pass a large commercial tractor-trailer. Compared to the blind spot on the left side of the truck, why is the blind spot on the right side (the right No-Zone) significantly more dangerous and expansive?
- The truck driver sits on the left side of the cab, causing the right-side blind spot to extend further back and cover more lanes than the left-side blind spot.Answer
- BThe right side of a commercial truck lacks convex side mirrors, preventing the driver from viewing vehicles alongside the trailer.
- CThe right-side blind spot only exists when the truck is executing a turn, whereas the left-side blind spot is constant.
- DTruck drivers use their interior center rearview mirror to monitor the right lane, which creates a larger blind spot zone.
Answer
The right-side No-Zone is larger and more dangerous because the truck driver sits on the left side of the cab, creating a longer and wider diagonal blind area along the right side of the vehicle.
The correct response accurately identifies that because truck drivers sit on the left side of the vehicle cab, their visual angle to the right mirror and window is obstructed by the cab and trailer length. Consequently, the right-side No-Zone begins at the cab and stretches backward diagonally across up to two lanes of traffic, making passing on the right particularly hazardous.
