Which of these statements about using mirrors is true?

Using mirrors is essential for safe driving, particularly for commercial drivers who need to be aware of their surroundings. The correct statement highlights that there are indeed blind spots that mirrors cannot fully cover. No matter how well you position your mirrors, certain areas around your vehicle remain outside the range of what they can show. These blind spots can be especially pronounced on larger vehicles like trucks and buses, where the size and shape create areas that are not visible in mirrors.

This understanding emphasizes the importance of physically checking these blind spots by turning your head before changing lanes or making turns. Relying solely on mirrors can lead to accidents, as they do not provide a complete view of all surrounding vehicles or obstacles. Effective driving requires both mirror use and awareness of these blind spots to ensure comprehensive visibility.
