What are "no-zones" related to heavy vehicles?

No-zones refer specifically to the areas around heavy vehicles, particularly large trucks and buses, where the driver has limited visibility or blind spots. These zones are crucial for other drivers to understand, as they represent spaces where a vehicle may not be able to see smaller cars or motorcycles. Familiarity with no-zones helps drivers maintain a safe distance and avoid potentially dangerous situations, such as merging into a lane where a truck driver cannot see them. Recognizing and respecting these areas is vital for ensuring road safety when navigating around large vehicles. The other options, while related to truck operations, do not capture the concept of no-zones, which centers on visibility limitations and the positioning of vehicles in relation to one another.
