Why isn't it illegal for big trucks to completely block traffic?

I feel like there is always a UPS truck or beer delivery truck that is parked all janky, and in order to get around them, I have to drive in the opposing lane of traffic.  Why isn't it illegal for them to do this?  Or is it, but no one ever calls them on it?  I've even seen a beer truck park completely across my street when delivering to the corner store....

EDIT:  Thanks for all the responses.  This wasn't as much a complaint about trucks blocking me, as I was just curious about whether or not they were legally allowed to park wherever, like some DOT classification.  I'll take a minor inconvenience of waiting anytime, so long as it means a fresh supply of delicious beer and groceries (in that order) :)

It is illegal. But the risk of getting caught is so small that its worth them to just do it anyway, in places like new york they hve no choice... Finding a parking spot for every delivery would slow them down so far as to drive them out of business.  

They do get caught and they do get tickets, its just worth the risk for them.
