Study: Elderly Drivers Need More Traffic Signs

Hemera Technologies/Thinkstock(JERUSALEM) -- A new Israeli study says elderly drivers may need more traffic signs alerting them to the presence of pedestrian crossings and other potential hazards.

When drivers over 65 get behind the wheel, they're only half as likely to see pedestrians on the sidewalk as younger drivers, according to  researchers in Israel. They've concluded that the limited field of vision often found in the elderly significantly impairs their ability to detect pedestrian and other hazards while driving. Tested on a traffic simulator, they responded slower and hit the brakes 50% less than younger drivers.

To compensate, the study found the elderly drive slower -- up to 20% slower, in fact -- to give them more time to detect problems.
