The Virginia Department or Motor Vehicles says crashes like Patnaude's only occurred six times last year in Virginia. Specifically meaning a crash in which a teenage passenger was killed while a teenage driver was behind the wheel.
John Saunders, a DMV director, said the crash raises awareness about the need for safety for teenage drivers.
New laws passed in 2013, make it so 17-year-old drivers can generally only have one teenage passenger in their car if they have had their license less than a year.
Teens that age can have no more than three teenage passengers in their car, if they have had their license for over a year.
"We want them to focus on the task of driving," Saunders said while speaking about the law.
While its unclear how long the driver in this crash had his license, it is clear that what happened remains on friends minds.
"I am amazed at how people come together," Payge Patnaude said, emphasizing that the family's faith in God is getting them through this difficult time.
