Question

Difficulty: EasySharing the Road with Large Vehicles

When driving directly behind a large commercial truck, if you cannot see the truck's side mirrors, the truck driver cannot see your vehicle.

Answer: Answer

Answer

True
The statement is true because commercial trucks have substantial blind spots directly behind their trailers. When you cannot see the truck's side mirrors, you are hidden within the driver's rear blind spot.

Step-by-Step Solution

1
Identify the visibility constraints of large commercial trucks.
Large trucks do not have center interior rear-view mirrors and rely strictly on large side mirrors to observe traffic behind them.
The body of the trailer completely blocks any direct rear view from the cab.
2
Apply the rule of thumb for sharing the road with large vehicles.
If a trailing driver cannot see the truck's side mirrors, the passenger vehicle is located inside the truck's deep rear blind spot (No-Zone).
If the mirror is not visible to you, light cannot travel from your vehicle to the driver's eyes via that mirror.

Key Concept

Large commercial trucks have large blind spots (No-Zones) directly behind them, and driver visibility depends entirely on clear line-of-sight through side mirrors.
