Driving on a suspended license can be a criminal or civil case in Florida. Too many charges of driving while suspended can result in a 5-year revocation of a driver's license as a habitual offender.
Almost every week I hear from people who have just been informed that they have been habitualized in the worst way. Apparently, ordinary people (not defense lawyers) trust the government and just pay a fine on a traffic ticket, especially when that fine is overdue. A common complaint will go something like this: "I just paid a ticket to get my license back and now I am being told that I am a Habitual Traffic Offender and my license is gone for five (5) years." Almost always the ticket that was paid recently is for driving on a suspended license.
