Can you look up how much you owe from fines and flags online?

Yes, the DMV has a website. You put in your drivers license number and it will tell you everything you need to do. All the flags or unpaid tickets. https://www.dmv.org

Make sure you are sitting down and NOT in a public place if you have more than 2-3 flags. Be prepared to dip into your savings, do yourself and your MONEY a HUGE FAVOR, have your insurance on Auto Pay each month to avoid being even ONE day late. Even 1 day past due and you will have a flag.
