Irony defined: who enforces the enforcers?
I could be wrong, because I'm no attorney, but... There doesn't appear to be an exception in the city's parking ordinance for non-emergency vehicles. And I've never heard an emergency overtime parking call go out over the police radio. To top this off, the parking enforcement vehicle is parked under the 8th Street viaduct at the police parking office, where there were empty spaces available for parking enforcement vehicles a few feet away at the time this photo was taken. The reason for no-parking zones is always for public safety. Where they're placed nearly always improves sight lines, making motoring safer in general. But restricting parking isn't just for cars. As the Federal Highway Administration points out, parking creates a visual barrier between motor vehicle traffic and crossing pedestrians, especially children and people using wheelchairs.
