When visibility is reduced to how many feet or less due to atmospheric conditions can a strobe light be used?

The use of a strobe light becomes important for safety when visibility conditions are poor. The correct answer indicates that when visibility is reduced to 500 feet or less due to atmospheric conditions, utilizing a strobe light is appropriate. This regulation enhances the visibility of the vehicle in low-light or foggy conditions, helping to ensure that other drivers can see the bus from a distance, which is crucial when transporting students.

Visibility below 500 feet significantly increases the risk of accidents as other vehicles may not recognize the presence of a bus. By activating the strobe light in these conditions, the bus operator takes an important safety measure, alerting other road users to their presence and ensuring that student passengers are transported safely. This rule reflects best practices in promoting safety for both passengers and drivers in adverse weather conditions.
