What is the significance of checking blind spots?

Answer: B — They help to see vehicles not in mirrors

Checking blind spots is crucial for safe driving because they are areas around your vehicle that cannot be seen in your mirrors. Often, vehicles, especially smaller ones, can slip into these spaces, making them invisible to the driver. By checking blind spots before changing lanes or merging, a driver can ensure that there are no vehicles or obstacles that may lead to a collision. The significance of this practice becomes especially pronounced when considering situations such as lane changes, turns, or merging onto highways. Even well-positioned mirrors will not cover every angle around your vehicle. Thus, actively turning your head to check these spots can prevent accidents and enhance overall road safety. Keeping aware of blind spots is a fundamental aspect of defensive driving, where the objective is to anticipate potential hazards from all directions.
