"No zone" refers specifically to the areas around a large truck where visibility is restricted, also known as blind spots. Large trucks have significant blind spots on all sides, which can make it difficult for the driver to be aware of the vehicles and pedestrians around them. Understanding the concept of "no zones" is vital for all drivers, as it highlights the importance of maintaining a safe distance from large trucks. When other vehicles occupy these areas, they are at a much higher risk of being involved in an accident because the truck driver may not see them.

The other options pertain to different contexts: areas designated for emergency stops serve a specific purpose related to safety and are not linked to visibility issues; zones marked for speed limits are related to traffic control and speed regulations; and “no parking” areas near highways focus on parking restrictions rather than driving visibility. Understanding "no zones" can significantly enhance safety on the road by promoting awareness of truck blind spots.
