A Petawawa teen died instantly when her car was struck from behind and burst into flames.

OPP say 17-year-old Emily Watts was stopped to make a turn on Laurentian Drive in the Ottawa Valley town at about 10:15 last night when her vehicle was rear-ended.

Her 2003 Honda caught fire. She died before firefighters could pull her from the wreckage.

A 28-year-old woman was arrested at the scene.

Media reports say Patricia Boyce of Petawawa has been charged with impaired driving causing death, dangerous driving causing death, and criminal negligence causing death. She will appear in Pembroke court Monday for a bail hearing.
