In a true, code-red taco emergency (aka tacomergency), a first responder needs the proper vehicle. Unfortunately, this ready-to-rock taco truck (tacombulance?) is only a movie prop, so 911 operators will just have to keep routing tacomergency calls to Baja Fresh.
Makes sense that this is only a prop. I doubt law enforcement would allow a vehicle that so closely resembles a EMT bus to drive around, especially if no real EMTs were aboard. The Ecto-1 could probably get away with it, but not this. Still, very cool.
