Step-by-step explanation:
If a license is issued before your 21st birthday, it will typically expire a few years after it is issued. The specific expiration date will vary depending on the state or country that issued the license. For example, in some states in the United States, a driver's license may expire on the license holder's 21st birthday, while in other states, it may expire a certain number of years after it is issued, such as five or six years.
In general, the expiration date is determined by the authorities that issue the license and is usually indicated on the license itself. It's important to check the expiration date regularly to ensure that you renew your license on time and avoid driving with an expired license, which can result in fines or penalties.
