Rules aim to define an unsafe driver

Would remove age, illness as factors

More than two years after a string of high-profile accidents by older drivers, Massachusetts health regulators are slated to vote Wednesday on rules that will, for the first time, define what it means to be too physically or cognitively impaired to drive safely. The rules make clear that age and illness are not by themselves disqualifying.

Instead, the decision will be based on ‘‘observations or evidence of the actual effect’’ that an impairment may have on a person’s ability to safely drive, according to the proposed rules, developed after months of public hearings and advice from medical specialists.
