Fla. Stat. §322.03(1) (1) Except as otherwise authorized in this chapter, a person may not drive any motor vehicle upon a highway in this state unless such person has a valid driver's license under the provisions of this chapter.

(a) A person who drives a commercial motor vehicle shall not receive a driver's license unless and until he or she surrenders to the department all driver's licenses in his or her possession issued to him or her by any other jurisdiction or makes an affidavit that he or she does not possess a driver's license. Any such person who fails to surrender such licenses or who makes a false affidavit concerning such licenses is guilty of a misdemeanor of the first degree, punishable as provided in s. 775.082 or s. 775.083.

(b) A person who does not drive a commercial motor vehicle is not required to surrender a license issued by another jurisdiction, upon a showing to the department that such license is necessary because of employment or part-time residence. Any person who retains a driver's license because of employment or part-time residence shall, upon qualifying for a license in this state, be issued a driver's license which shall be valid within this state only. All surrendered licenses may be returned by the department to the issuing jurisdiction together with information that the licensee is now licensed in a new jurisdiction or may be destroyed by the department, which shall notify the issuing jurisdiction of such destruction. A person may not have more than one valid Florida driver's license at any time.
