Taking Multiple Medications Can Increase Crash Risk for Older Drivers

WASHINGTON, D.C. (Nov. 28, 2018) – Nearly 50 percent of older adults report using seven or more medications while remaining active drivers, according to new research from the AAA Foundation for Traffic Safety. An evaluation of the medications people are taking found that nearly 20 percent of older drivers are using medications that generally should be avoided because they have very limited therapeutic benefit, pose excess harm, or both. Drugs like these are called potentially inappropriate medications, or PIMs1. Most of these potentially inappropriate medications, such as benzodiazepines and first-generation antihistamines, are known to cause impairing effects such as blurred vision, confusion, fatigue or incoordination, and can increase a driver’s risk for a crash by up to 300 percent2.
In 2016, more than 200,000 drivers ages 65 and older were injured in traffic crashes and more than 3,500 died. Currently, a record 42 million adults ages 65 and older are driving on America’s roads and this number is expected to increase substantially over the next decade, which would make them the largest driving population.
“There is a growing population of older drivers who use multiple medications and likely do not realize the impact these prescriptions may have on their driving,” said Dr. David Yang, executive director of the AAA Foundation for Traffic Safety. “This new research shows that the more medications an older driver takes, the more likely they are to use an inappropriate medication that can potentially cause driving impairment.”
