RADNOR, Pa. (CBS) — Radnor Township police were outside Radnor High School at dismissal time this afternoon, stopping every car as it drove out of the parking lot.

“All to save lives,” says sergeant Chris Flanagan of the “teen mobilization event.”

“We’re here to make teen drivers aware about the new laws that changed at the end of December 2011,” Flanagan (at right in photo) explained.  “We have a new violation which is a primary offense, which means officers can stop any driver who has an occupant under the age of 18 seated in any part of the vehicle without a seatbelt on.  And (we can) issue a citation for that.  And that is a big change from how it used to be.”

Diana and Maura, who attend the school, didn’t mind being stopped.

(Diana:)  “Not at all!  I don’t mind — I always wear my seatbelt.”

(Maura:)  “Me too!”
