Can ATV's be street legal in Alabama?

I was told today by an AL state trooper that I can "street legal" a arctic cat 500 TBX I have. I have started researching it and I am in the process of getting it regsitered and licensed in AL. I was told by the trooper that the bike had to have a license plate, turn signals, and had to be insured. I called my insurance company to get the quote today. It will change my policy by $21 a month. I plan on going to the probate on Monday to get the registration started and i will keep you posted.
