A recent change to how Arizona motorists can choose to be an organ and tissue donor has coincided with a nearly 20 percent increase in the number of people signing up for this important cause. Since October of 2017, ADOT MVD customers have been able to register as donors when renewing a vehicle registration at ServiceArizona.com. Previously, that decision could only be made when a driver was getting a new or updated driver license or ID card. Officials say because Arizona licenses are valid until the customer turns 65, and photo updates occur every 12 years, the chances for customers to make this selection were limited. By contrast, vehicle registration renewals for most occur every one to two years. For more information on being an organ tissue donor go to azdot.gov or DonateLifeAZ.org
