To know if your driver's license is suspended, the most common and convenient way is to check online through your state’s Department of Motor Vehicles (DMV) or equivalent agency website. Typically, you need to:

• Visit the DMV website of the state that issued your license.
• Create an account or log in if you already have one.
• Provide some personal information such as your driver's license number, date of birth, and sometimes your Social Security number.
• Check your driver license status, which may show if your license is valid, suspended, revoked, or expired.
• You may also be able to view any violations or points on your record.

If you do not have online access, you can usually contact the DMV by phone, visit in person, or mail a request to get your license status. Specific services exist in states like Florida, Georgia, New York, Texas, Washington, and Wisconsin to verify license status online securely and check for suspensions.

Driving with a suspended license is illegal and may result in fines or other penalties, so it’s important to check your status regularly or if you suspect any issues.
