What type of driver's license is issued to individuals over the age of 21 in Florida?

In Florida, individuals over the age of 21 are issued a horizontal driver's license. This design choice distinguishes adult licenses from those issued to younger drivers, specifically those under 21, who receive a vertical driver's license. The horizontal format for those over 21 is not just a matter of aesthetics; it also serves an important identification function. It helps law enforcement and other entities quickly recognize the age of the driver, which can be crucial for verifying eligibility for various activities that may have age restrictions, such as purchasing alcohol. This distinction promotes public safety and helps to deter underage individuals from misusing identification. The other options, vertical, diagonal, and round, do not correspond with the licenses designated for individuals over 21 in Florida's licensing system.
