When do you activate the strobe light on a school bus?

Answer 1

Regarding the DANGERS OF STROBES:

Folks, these strobes are far more dangerous than they are good. As a pilot, one must turn off strobes in fog, rain, snow due to vertigo.

This is the same on the ground as it is in the air. Why would you wish to "blind" drivers following a bus, particularly over a long distance. These strobes SHOULD BE OUTLAWED and NOT USED.

Wikipedia:

Flicker vertigo is "an imbalance in brain-cell activity caused by exposure to low-frequency flickering (or flashing) of a relatively bright light"

[1] The strobe light effect causes persons who are vulnerable to flicker vertigo to become disoriented, lose control of the aircraft (Vehicle).

Due to the intensity of the brilliant white light source, the intended use for strobes is during daylight hours of operation.

Strobes should really not be used in inclement weather, in the clouds or on the ground as this can cause flicker vertigo. BUT THIS IS WHEN MOST BUS DRIVERS USE THE STROBES ! THE WORST TIME TO HAVE THEM ON!!!!

Aviation FAR 91.209-You must use position and anti-collision lights between sunset and sunrise, but this regulation says you can turn off the anti-collision lights for safety, such as when flying in precipitation.

Distractions and problems can result from a flickering light in the cockpit, anticollision light, strobe lights, or other aircraft lights and can cause flicker vertigo. If continuous, the possible physical reactions can be nausea, dizziness, grogginess, unconsciousness, headaches, or confusion. The pilot should try to eliminate any light source causing blinking or flickering problems in the cockpit.

Flicker vertigo has been reported as the cause of some aviation accidents. Twenty two percent of helicopter pilots and 30 percent of airplane pilots said flight through fog with a rotating beacon had caused flickering light in the cockpit.

At night, anti-collision lights reflecting off the clouds can produce the effect. Flicker vertigo can develop when viewing rotating beacons, strobe lights, or reflections of these off water or the clouds.

With the above information readilly available, Did the transportation board fail to do their research prior to having these installed?

Have they ever travelled 15 minutes behind a bus with strobes in the dark, and rain? IT IS VERY BLINDING and DISTRACTING

If they don't feel a large yellow vehicle is visible enough, add reflective paint, more lighting (Like some trailer trucks)

But not a Blinding strobe light!

Answer 2

The strobe light on a school bus is typically activated during conditions of low visibility such as fog, heavy rain, or snowstorms. It helps improve the visibility of the bus to other drivers on the road, alerting them to the presence of the school bus and encouraging them to exercise caution. It is important for drivers to follow local regulations and guidelines regarding the use of strobe lights on school buses.
