How frequently should a bus operator check blind spots?

A bus operator should check blind spots constantly, particularly before making lane changes and turns, to ensure the safety of all road users. This practice is essential because blind spots can hide other vehicles, pedestrians, or cyclists who may not be visible in the mirrors. By consistently monitoring these areas, operators can make informed decisions about their maneuvers, mitigating the risk of collisions.

The importance of this vigilant checking aligns with safety protocols and guidelines that emphasize the necessity of being aware of the surrounding environment at all times. Continuous awareness helps maintain not just the safety of the bus operator but also of passengers, pedestrians, and other vehicles on the road.

While checking blind spots every few minutes might seem reasonable, it does not account for the dynamic nature of driving where conditions can change rapidly. Limiting checks to only when approaching intersections may lead to dangerous situations, as dangers can arise at any point along a route. Similarly, only checking blind spots upon hearing a noise can lead to delayed responses to imminent hazards. Hence, the emphasis is placed on the need for constant vigilance in checking blind spots during all driving situations.
