Drivers may experience a so-called "hangover effect," where their brain remains distracted for up to 27 seconds after talking or texting, according to a study prepared by the AAA Foundation for Traffic & Safety. Accordingly, distracted driving is joining other reckless conduct like drunk driving and speeding as the cause of many traffic accident deaths and injuries.
This hangover effect has previously unforeseen consequences. Text messaging, making phone calls or updating social media while parked or at a stop light still impedes the driver's concentration after the car begins moving again. This often causes inattention blindness, where a distracted driver is looking at the road but is still not seeing pedestrians, other vehicles, cyclists, traffic lights, stop signs or anything else in front of them.
