"Pennsylvania is a very difficult state for highway safety," said Jonathan Adkins, a spokesman for the national Governors Highway Safety Association.
He said the state "has fallen behind other states" in lifesaving areas such as banning cell phones, making failure to use seat belts a primary offense, and imposing restrictions on teen drivers.
Police said Montgomery "Monte" A. Wood, an aspiring Eagle Scout, had sneaked out with some Twin Valley High School classmates about 3 a.m. July 16 in a high-powered Mitsubishi Lancer Evolution.
A joyride up and down Beaver Dam Road in Honey Brook Township followed what police termed a "campout" at Wood's nearby home and ended with the deaths of Wood and his front-seat passenger, Britany Pearl Leger, 15, of Honey Brook Borough.
Two other passengers, Damien Paterno and Cameron Merlino, both 15, are recovering from injuries. Police said none of the teens had a driver's permit or license.
Flaura Winston, a pediatrician who founded and directs the Center for Injury Research and Prevention at Children's Hospital of Philadelphia, said the crash - like many others - highlighted the need to impose passenger limits on teen drivers.
"There's a different brain pathway that starts working when teens are together," she said. "You mix an Eagle Scout with a bunch of friends and something else emerges."
Winston said that even though it was unlikely a law would have prevented the Honey Brook tragedy, she was frustrated by the state's "epidemic of teen crashes."
Since 2005, more than 500 teen drivers and 300 of their passengers have died in Pennsylvania, Winston said, adding that teen drivers had killed 300 other people as well.
"If there was some other epidemic killing kids this fast, we would demand that the killer be stopped, yet we tolerate this," she said.
As passed by the House in April 2009, H.B. 67 would have limited teenage drivers to one nonfamily passenger younger than 18 and added 15 hours of required driver training.
