When should aerial apparatus drivers check their side and rear view mirrors?

Aerial apparatus drivers should check their side and rear view mirrors before changing lanes and at all times when driving to ensure safety and awareness of their surroundings. Regular monitoring of mirrors is crucial, especially given the size and weight of aerial fire apparatus, which can have numerous blind spots. Checking mirrors helps drivers identify other vehicles, pedestrians, or obstacles that may not be visible from their primary viewpoint. This practice not only informs lane changes but also assists in maintaining a safe driving environment at all times, preventing potential accidents. Consistently checking mirrors contributes to overall situational awareness, which is vital for effective operation in varying traffic conditions.
