Final answer:
The large blind spots on each side of a truck or bus are called no-zones. These blind spots pose a significant safety hazard, and it is important for drivers to avoid these areas to ensure road safety.
Step-by-step explanation:
The large blind spots on each side of a truck or bus, where a car cannot be seen, are called no-zones. These blind spots are significant safety hazards because the driver of the larger vehicle cannot see smaller vehicles such as cars, which might be overtaking or passing by. It is crucial for all drivers, especially those operating smaller vehicles, to be aware of these no-zones to prevent accidents and ensure road safety. Typically, these no-zones are located directly behind the vehicle, on both the immediate left and right sides near the rear of the truck or bus, and right in front of the vehicle.
For safety, it is advisable for drivers of smaller vehicles to avoid lingering in these areas and to be cautious when passing trucks or buses, making sure to signal early and to move out of the no-zone as quickly and safely as possible. Drivers of large vehicles are trained to regularly check mirrors and take precautions, but it's a shared responsibility on the road to minimize the risk associated with blind spots.
