We get frost heaves that will rip the front end off a vehicle if you don't know they are there. The state goes around and puts up "BUMP" signs all over the place.Frost heave signs are used also. They show up in the same places every year. Last year where it was so cold they were even worse than normal. Maine roads in general are awful to begin with and once febuary comes around they get even worse until sometime in April depending on the locale
