While driving on a roadway with multiple lanes traveling in the same direction, you find yourself traveling in the lane directly to the left of a large commercial tractor-trailer. Why is it unsafe to remain in this position for an extended period of time?
- The tractor-trailer still has a significant left-side blind spot that can hide your vehicle from the driver's view.Answer
- BCommercial truck drivers have full side-mirror visibility on their left side, so cruising there forces the truck to reduce speed.
- CLarge commercial trucks are legally required to change lanes to the left whenever another vehicle approaches from behind.
- DTraveling beside the cab of a commercial vehicle automatically disables your vehicle's side-collision warning systems.
Answer
The tractor-trailer still has a significant left-side blind spot that can hide your vehicle from the driver's view.
Large commercial trucks have blind spots (No-Zones) on the front, rear, and both sides. Although the left-side No-Zone is smaller than the right-side No-Zone, it still extends along the side of the truck. Lingering beside a truck makes it difficult or impossible for the truck driver to see your vehicle in their side mirror.
