School Bus Moving With Flashing Red Lights - But Not Stopped
What is the requirement for stopping when a school bus is traveling down the roadway, initiates the flashing red lights while still moving but has not yet stopped? If a motorist is traveling through an intersection (through the free-flow approach, minor-street stop controlled) and an oncoming school bus initiates the lights while approaching the intersection, but is still moving and has not come to a stop nor has the stop sign been activated), is the motorist expected to slam on the breaks within the intersection and come to a stop even though the bus is moving and approaching the intersection? What's the protocol here? My interpretation is that the bus driver activates the flashing overhead red lights while approaching it's destined stop as a warning to other motorists that a stop is imminent (similar to that of an amber signal indication - stop if you can safely do so but the expectation is not that you slam on the breaks in the middle of the intersection the instant the indication changes from green to amber). Is this grounds to be charged with an offense even though the school bus was still moving?
Is there any onus on the school bus driver to use judgement when approaching a bus stop and to activate the lights when "safe" to do so - not when an oncoming car is a cars length from your bumper then lay on the horn at the driver as the bus passes them?
What about the instance where you see an oncoming bus, lights are activated (bus is approaching and is still moving). You stop, yet the bus continues past you to pick up kids at a stop further down the way - seems confusing.
Long question short - if the oncoming bus is still moving, then initiates the overhead flashing red lights, if you pass the bus while it's still moving are you at risk of being charged? Or is the offense in passing a STOPPED school bus with flashing red lights activated (regardless if the stop sign is out or not).
Thanks.
