In a recent study by the Insurance
Institute for Highway Safety (IIHS), the number of drivers, age 70 and older, involved in fatal accidents on U.S. roads declined about 20 percent from 1997 to 2006. However, during that same time period, the number of fatal accidents among drivers ages 35 to 54 dropped only slightly. The most notable aspect of the study is that the amount of drivers over the age of 70 increased by about two million and the total miles driven by this age group went up by 30 percent. The IIHS did not have a clear reason for their findings, but they did conclude that elderly drivers are likely limiting the amount of driving they do and when they do it, which contributes to the decline.
