Here in Winnipeg, it is VERY common to see front end loaders, graders, etc.. traveling down major routes. We don't really have any freeways.
Does anyone know of any major American city that allows this? I can't honestly say I know of any.
I'm not talking about clearing snow either, it happens all the time in the middle of the summer.
Farm equipment, front loaders, graders, hell I've even seen small bulldozers!
