The Iowa Department of Transportation today unveiled a new online driver's license renewal system. Eligible drivers will be able to renew their license 24 hours a day, seven days a week, from any computer or mobile device. Drivers are eligible, with some exceptions, if they are older than 18 and younger than 70, have a license that has not been expired for more than a year, do not have any medical or vision conditions that could impair their ability to drive and don't need to change the address on their card.
