I'm not sure how the law is actually interpreted but the NPSPAC 800 MHz frequencies are ostensibly for "public safety" usage only, It's very much a question for interpretation as to whether or not specific activities qualify as 'public safety' concerns. Something tells me that while you might argue for a legitimate need for road and bridge crews, and maybe even for school bus traffic, when it comes down to public transportation, you're now in a very dark grey area. I don't think the SCAT buses should be on the system, in fact I question whether even Coastal non emergency transport qualifies. Certainly Harris corporate security doesn't.
