How can a driver avoid blind spots?

Answer: B — Use mirrors and check over the shoulder

Using mirrors and checking over the shoulder is the most effective way for a driver to avoid blind spots. Mirrors provide a view of the surrounding area, but they cannot cover every angle; there are areas that may not be visible in the mirrors, known as blind spots. By looking over the shoulder, a driver can gain better awareness of vehicles or obstacles that may not be reflected in the mirrors. This combined approach ensures that the driver has a more comprehensive view of their surroundings, particularly before changing lanes or merging. While driving with the windows down may enhance sensory awareness in terms of sound, it does not contribute significantly to visual awareness, which is crucial for spotting vehicles in blind spots. Relying solely on side mirrors ignores the potential for vehicles to be located in those blind areas that mirrors do not capture. Signaling before changing lanes is certainly important for communication with other road users but does not directly help in identifying blind spots. Therefore, consistently using mirrors in conjunction with shoulder checks is essential for safe driving and minimizing the risks associated with blind spots.
