What does the term 'blind spot' refer to in driving?

The term 'blind spot' specifically refers to areas around the vehicle that cannot be seen in the mirrors. When drivers look in their side or rearview mirrors, there are certain zones that remain out of their line of sight. These blind spots are often located directly beside and behind the vehicle, where other vehicles or objects may be positioned without the driver being aware of them. This lack of visibility can create dangerous situations, especially during lane changes or merges, which is why it’s important for drivers to physically turn their heads and check these areas before maneuvering. By understanding where blind spots exist, drivers can take proactive measures to ensure safer driving practices, such as using turn signals, checking over their shoulders, and maintaining awareness of their surroundings.
