Not Your Lucky Day, Bud

By now, every driver should know that parking near, more so beside or in front, of a fire hydrant is a violation; lest they want to suffer the same fate as the vehicle owner in this image. According to the law in the United States, public parking must be 15 feet away in both directions, whether or not the curb is painted.

Well, firefighters can smash windows in the way of the hose and the fire hydrant. This is especially true if they deem that the pressure would be better this way than if the hose goes under or over a vehicle.
