Which of the following is a key benefit of using mirrors effectively?

Using mirrors effectively helps in preventing blind spots, which is a critical safety measure for any commercial driver. Blind spots are areas around a vehicle that are not visible through standard mirrors. By properly adjusting and utilizing mirrors, a driver can gain a better awareness of their surroundings, including other vehicles, pedestrians, and obstacles. This increased visibility is vital for safe lane changes, turns, and overall navigation on the road.

When blind spots are minimized, the chances of accidents are significantly reduced, thereby enhancing overall road safety. This skill is particularly important for large vehicles like trucks and buses, which have larger blind spots compared to standard passenger vehicles. Being able to detect and monitor these areas makes it easier to operate a commercial vehicle safely amidst traffic conditions.

The other options do not relate directly to the key safety benefit provided by effective mirror use. While faster driving, lower fuel consumption, and increased cargo space could be important for overall vehicle operation and efficiency, they do not specifically address the critical aspect of visibility and safety that mirrors provide.
