If you get pulled over by an officer and you have never become a licensed driver you will be charged with a violation of Florida Statute 322.03 (no valid drivers license), which is a second degree misdemeanor. This is a criminal charge and is punishable by up to 60 days in jail.
If you get pulled over by an officer and you are a licensed driver but you do not have your license on you, you will be charged with drivers license not carried and exhibited on demand. This is a violation of Florida Statute 322.15 and is a non-moving violation. If this occurs the officer must take your thumb print to later be able to prove that it was you that was driving. If he doesn’t the ticket is dismissible.
