Why is it essential to adjust your mirrors before driving a commercial vehicle?

Adjusting your mirrors before driving a commercial vehicle is essential because it ensures maximum visibility around the vehicle. Properly positioned mirrors provide the driver with a clear view of the areas surrounding the vehicle, including blind spots. This visibility is crucial for safe operation, as commercial vehicles are often larger and have more significant blind spots than regular vehicles.

By having optimal mirror adjustments, drivers can effectively monitor traffic, pedestrians, and any obstacles that may not be directly in their line of sight. This is particularly important when making lane changes, turns, or reversing. Mirror adjustment is a fundamental safety measure that significantly reduces the risk of accidents caused by lack of awareness of the surrounding environment.
