Nearly half of all drivers who say they feel less safe on roads today, compared to five years ago, cite distracted driving as the main reason, the AAA Foundation for Traffic Safety reported.

In 2014, distracted driving accounted for 10% of all crash fatalities, killing 3,179 people, according to the National Highway Traffic Safety Administration. At any given daylight moment, approximately 660,000 drivers are using cell phones or other electronic devices while driving.

Far too many people continue to overestimate their own ability to multitask while driving. AAA Foundation research has found that texting while stopped at a traffic light, for example, can negatively affect full driving engagement once the light turns green for an average of 27 seconds after the texting is stopped.

Of course, not all driving distractions involve electronics. Eating a snack, sipping coffee, changing the radio channel, fiddling with the navigation system — these are all distractions too.

You may want to pass this along to fleet drivers as a friendly reminder that driving always requires their full attention.
