How can the use of mirrors benefit a driver?

The correct choice highlights that mirrors allow drivers to see areas around and behind their vehicle. This visibility is essential for overall safety while driving, as it enables drivers to be aware of their surroundings and detect potential hazards that may not be visible from the driver's seat alone. By effectively using mirrors—such as side mirrors and the rearview mirror—drivers can make more informed decisions about lane changes, merging, and maintaining safe distances from other vehicles.

The other options, while they may touch on aspects associated with driving, do not accurately reflect the primary safety benefit of mirrors. Mirrors are not designed to enhance fuel efficiency or improve driving speed. Instead, their main purpose is to provide a wider field of view to reduce the potential for accidents. Additionally, while mirrors can help reduce blind spots, the main benefit is ensuring that drivers have a better view of the immediate areas around their vehicle. Mirrors play a crucial role in promoting safe driving practices by reducing the likelihood of collisions through increased awareness.
