The foregoing requirements shall apply when:

(B) A crossing gate is lowered or a human flagman gives or continues to give a signal of the approach or passage of a railroad train;
(C) A railroad train approaching a highway crossing emits a warning signal and such railroad train, by reason of its speed or nearness to such crossing, is an immediate hazard;
(D) An approaching railroad train is plainly visible and is in hazardous proximity to such crossing;
(E) A railroad train is approaching so closely that an immediate hazard is created. (1972 Code)
