(a) Every passenger van used for the transportation of children shall bear upon the front and rear thereof a plainly visible sign containing the warning “Caution: Loading and Unloading Passengers” in letters not less than six inches in height. Every such passenger van shall be equipped with either flashing warning signal lights as are contemplated and referred to in West Virginia Code 17C-12-8, or a red caution flag which the driver or some other adult must use by exiting the passenger van and displaying while assisting in the loading or unloading of passengers. Such vehicles may also be equipped with a white flashing strobotron warning light that meets the requirements set forth in West Virginia Code 17C-15-26(e).
(b) The driver of a vehicle upon meeting or overtaking from any direction any passenger van which has stopped for the purpose of loading or unloading passengers shall stop his or her vehicle before reaching the passenger van when there is in operation on the passenger van flashing warning signal lights or when an adult is outside the passenger van with a red caution flag and assisting with the loading or unloading of passengers. The driver of a vehicle may not proceed until he or she is signaled by the passenger van driver to proceed, the passenger van flashing signal lights are no longer actuated, or the passenger resumes motion. This section applies whenever the passenger van is loading or unloading children on any street, highway, parking lot, private road or driveway: provided, that the driver of a vehicle upon a controlled access highway need not stop upon meeting or passing a passenger van which is on a different roadway or adjacent to the highway and where pedestrians are not permitted to cross the roadway.
