(AREA) -- Secretary of State Ruth Johnson reminds customers that all branch offices and the Office of the Great Seal will be closed on Monday, September 2, in observance of Labor Day. Secretary of State SUPER!Centers normally offer Saturday hours but will be closed on Saturday, August 31. The Department of State mails notices to motorists 45 days before their driver's license or license plates expire to give them ample time to renew. Licenses and plates that expire on a day when state offices are closed, such as a holiday or weekend, can be renewed the following day without penalty. License plates may also be renewed online or at Self-Service Stations located inside branch offices.
