What does the term "no zone" refer to?

The term "no zone" specifically refers to the areas around large trucks where a vehicle may be in their blind spots. These blind spots are areas where a truck driver cannot see other vehicles unlike a passenger vehicle that has a much wider field of view. Understanding the concept of "no zones" is crucial for maintaining safe distances when driving near large trucks, as being in one of these blind spots can put a driver in a vulnerable position, increasing the risk of accidents.

Being aware of these zones helps drivers anticipate how to position their vehicles safely and avoid potential collisions, particularly when it comes to actions like changing lanes or merging. The other choices do not accurately capture the meaning of "no zone" in the context of driving safety and awareness around larger vehicles.
