The West Bridgewater Police Department will give parents tips about keeping their teens drug-free and safe behind the wheel during a safety night for families, set for 7 p.m., March 21, in the West Bridgewater High School auditorium. “We’ll talk about drug recognition, so parents will have an idea if their kids are falling into drugs,” Police Lieutenant Victor Flaherty said. “Then we’ll talk about distracted driving, to get parents to realize how dangerous it is.” Flaherty said the department has obtained 10 cell control monitoring devices that block young drivers from texting, web surfing, or e-mailing while at the wheel. Those will be given out as door prizes during the safety session. “The devices can also be used to restrict them from making calls while driving,” he said. “After a couple of months, we’ll ask for some feedback from parents on how they worked.” Police plan to also discuss safety measures in place at the local schools.
