What are "no zones" in relation to large trucks?

"No zones" refer specifically to areas around large trucks where smaller vehicles are not visible to the truck driver. Because of the size and design of large trucks, there are significant blind spots that can extend several feet behind the vehicle and alongside it. This means that if a car is in one of these "no zones," the driver of the truck may not be able to see it, which poses a serious safety risk for both the truck and the smaller vehicle. Understanding and recognizing these blind spots is crucial for drivers of passenger vehicles to ensure safe maneuvers around large trucks.

To ensure safety, it's important for drivers to be conscious of these "no zones" and to avoid lingering in these areas, especially when changing lanes or merging, thereby minimizing the risk of accidents. The other options do not accurately define "no zones," as they refer to concepts not directly related to visibility issues concerning large trucks.
