What do the "no zones" refer to in regard to commercial vehicles?

The term "no zones" specifically pertains to the blind spots around large commercial vehicles where smaller vehicles may be hidden from the driver's view. These areas are particularly critical for safety, as they pose a significant risk for accidents if other drivers are not aware of them. By understanding the location of these no zones, drivers can make safer decisions, such as avoiding lingering in those areas while driving close to large trucks and buses. Recognizing that commercial vehicles have larger blind spots can help in preventing collisions during lane changes or merging.

The other options describe different aspects of road safety and regulations but do not pertain to the specific concept of no zones associated with blind spots in commercial vehicle operation. Understanding these no zones is essential for both commercial drivers and those sharing the road with them to enhance overall safety.
