You don't (shouldn't) put people in prison for stuff like this, you keep fining them increasing amounts of money until they stop doing the thing they are not supposed to be doing. The world would be a much better place if the traffic (and waste) laws were more, maybe even automatically, enforced.

I think a point system is better than fines. Fines are effective deterrents for most people, but they are unfair on the poor.

You could also have fines proportional to income. Both fines and point systems have their caveats though.
