Why is it important to check blind spots prior to changing lanes?

Checking blind spots before changing lanes is critical for safety on the road. It helps to increase visibility and ensures that there are no vehicles or obstacles hidden from the driver's view. Blind spots are areas around your vehicle that cannot be directly seen through mirrors. These areas can conceal pedestrians, bicycles, or other vehicles, which could lead to collisions if not checked.

By performing a visual check of blind spots, a driver can verify that it's safe to change lanes, significantly reducing the risk of accidents. This practice is especially crucial in larger vehicles, such as trucks and buses, which have larger blind spots compared to standard passenger cars. Thus, continuously monitoring these areas engages the driver in safer driving practices and fosters a more aware driving environment.
