Many people expect, or hope, that the family doctor will intervene to help take away the car keys from an unsafe older driver, but doctors and clinic staff say these are hard conversations to have and they need more resources. "Doctors are often called on to help make decisions about driving, because they understand a person's medical conditions and medications and how these affect driving," but many older adults prefer to hear advice from family, friends or driving specialists, said lead author Dr. Marian E. Betz of the Department of Emergency Medicine at the University of Colorado School of Medicine in Aurora.
