Think You Know All About Distracted Driving?

Hands-free technologies might make it easier for motorists to text, talk on the phone, or even use Facebook while they drive, but new findings from the AAA Foundation for Traffic Safety show dangerous mental distractions exist even when drivers keep their hands on the wheel and their eyes on the road.

The research found that as mental workload and distractions increase reaction time slows, brain function is compromised, drivers scan the road less and miss visual cues, potentially resulting in drivers not seeing items right in front of them including stop signs and pedestrians. This is the most comprehensive study of its kind to look at the mental distraction of drivers and arms AAA with evidence to appeal to the public to not use these voice-to-text features while their vehicle is in motion.

With a predicted five-fold increase in infotainment systems in new vehicles by 2018, AAA is calling for action as result of this landmark research. “There is a looming public safety crisis ahead with the future proliferation of these in-vehicle technologies,” said AAA President and CEO Robert L. Darbelnet. “It’s time to consider limiting new and potentially dangerous mental  distractions built into cars, particularly with the common public misperception that hands-free means risk-free.”

Cognitive distraction expert Dr. David Strayer and his research team at the University of Utah measured brainwaves, eye movement and other metrics to assess what happens to drivers’ mental workload when they attempt to do multiple things at once, building upon decades of research in the aerospace and automotive industries. The research included:

  • Cameras mounted inside an instrumented car to track eye and head movement of drivers.
  • A Detection-Response-Task device known as the “DRT” was used to record driver reaction time in response to triggers of red and green lights added to their field of vision.
  • A special electroencephalographic (EEG)-configured skull cap was used to chart participants’ brain activity so that researchers could determine mental workload.
