The list of advice for parents of teen drivers is long.
Have a firm stance against alcohol, always know the other kids they're out with, don't let them drive with a car full of teens, have firm rules and expectations with consequences if they're broken, be a good role model.
But experts say it comes down to hands-on, tough parenting and fighting off a desire to want to be your teen's friend.
"Too often, parents want to give away their responsibility as parents to the schools," said Bruce Novak, superintendent of the Cambridge-Isanti School District, where three high school students died and one was injured in a fiery weekend crash that killed three others. "We're supposed to take care of all those issues and concerns that they're maybe uncomfortable with because they want to be the friend of their child. But our children need parents to guide them directly."
The community is reeling in wake of the crash, whose sole survivor, the 16-year-old driver of the students' car, had received her license three weeks earlier.
Authorities have said she could face criminal charges; she was driving after curfew and was carrying more passengers than allowed by law.
The accident has left parents and experts grappling with how to prevent another tragedy.
Parents, not pals
