|There's a fire station near the intersection, and fire trucks are another type of vehicle that sometimes has the ability to preempt the normal flow of traffic so that they can get through the area quickly. It should have read something like "No Emergency Vehicle Preemption" but maybe their supplier was out of those signs.|
