A 16-year-old boy has been cited for using his cellphone while driving after causing a head-on crash in Pepperell last week, according to Pepperell police.

On Thursday, police responded to report of a crash on Main Street just before 11:20 a.m. According to police, the teen driver crossed into the opposite lane, striking an SUV head-on.

The woman driving the SUV sustained serious but non-life-threatening injuries to one of her legs, and was transported by a medical helicopter to UMass Memorial Medical Center in Worcester.

“I cannot stress enough how dangerous it is for drivers to be distracted while at the wheel,” Pepperell Police Chief David Scott said in a statement. “Anything that takes your attention away from the road, even for one second, can have devastating consequences. Please stay off of all electronic devices while driving, even if you are sitting in traffic, programming a GPS or changing the radio.”
