Distracted driving is a problem for all drivers, but teens are at higher risk.
Yes, it's true that drivers under 25 are up to three times more likely to send text messages or emails while behind the wheel than older drivers, according to the National Highway Traffic Safety Administration.
But there's a deeper problem: Teenagers are also at a developmental stage where getting distracted is more problematic than it is for older drivers.
After five years of crisscrossing the country as a traveling medical technician, David Kwiatkowski landed at New Hampshire's Exeter Hospital in the spring of 2011. A full-time job in the hospital's cardiac unit soon followed.
It was at Exeter that federal prosecutors say the 33-year-old began to divert syringes of the drug Fentanyl. They say Kwiatkowski, who was arrested July 19, would inject himself with the painkiller, and then refill syringes with a saline solution. He is hepatitis C-positive, meaning those tainted needles might have spread the liver-damaging virus.
