Blind spots are areas around a truck or other heavy vehicle where other vehicles cannot be seen by the driver. These areas can lead to accidents if not properly checked. Drivers should be aware of blind spots and take precautions to ensure safety.
Step-by-step explanation:
Blind spots are areas around a truck or other heavy vehicle where other vehicles cannot be seen by the driver. These areas exist because the driver's field of vision is limited to the front and sides of the vehicle. Blind spots are especially dangerous because they can lead to accidents if a driver attempts to change lanes or make a turn without properly checking their surroundings. It is important for drivers to be aware of blind spots and take precautions, such as using side mirrors and blind spot detectors, to ensure the safety of themselves and others on the road.
