Recently the 5th District Court of Appeal held that a passenger of a vehicle is lawfully seized and not free to leave a traffic stop. Therefore, if evidence of a crime is found, it can be used against the passenger. A large amount of drug possession cases and other criminal cases start with a traffic stop and subsequent search of passengers.
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.
