What does the "no-zone" concept refer to in commercial driving?

The "no-zone" concept in commercial driving specifically refers to the blind spots around a vehicle where visibility is limited. These areas, which include the front, back, and sides of the vehicle, can make it difficult for drivers to see other vehicles, particularly smaller ones, pedestrians, or cyclists. Understanding the no-zones is crucial for both commercial drivers and motorists sharing the road, as it emphasizes the importance of avoiding these areas to prevent collisions. By being aware of the no-zone regions, drivers can make safer maneuvers and enhance overall road safety. This concept is especially significant in larger vehicles, such as trucks and buses, due to their size and the significant blind spots they possess.
