Secretary of State Ruth Johnson is reminding residents that all branch offices and the Office of the Great Seal will be closed in observance of Martin Luther King Jr. Day on Monday, Jan. 21. 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. Most people renewing license plates, driver’s licenses and ID cards can do business online atwww.ExpressSOS.com or by mail. Easy to follow instructions can be found with the renewal notice. Additional services can be done online as well. License plate tabs can also be renewed at Self-Service Stations, many of which are available around the clock. Visit the Branch Office Locator at www.michigan.gov/SOS to find a Self-Service Station near you.With the exception of holidays, offices are open Monday, Tuesday, Thursday and Friday from 9 a.m. to 5 p.m. Smaller offices may close for the lunch hour. On Wednesdays most offices are open from 11 a.m. to 7 p.m., with those in city centers open 9 a.m. to 5 p.m. PLUS offices and SUPER!Centers are open from 9 a.m. to 7 p.m. on Wednesdays.
