AAA says the "100 Deadliest Days" of teen driving in 2017 have begun.

According to AAA, teen drivers are 300 percent more likely to be killed in a crash between Memorial Day and Labor Day.

"It makes sense," says AAA spokesman Robert Sinclair. "The kids are out of school, they're out on the roads in greater numbers and they lack the skills and experience that most drivers have."

A wrecked car sits on the lawn outside West Babylon High School to warn students of the 100 days.

AAA's traffic safety foundation released videos of actual teen crashes and statistics showing that teen crashes killed more than 1,800 people in 2015 -- an alarming increase of 10 percent over the previous year. AAA blames teens' inexperience, texting, alcohol consumption and not using seat belts.

Dr. Dawn Nappi, who lost her teen in a crash nine years ago, stresses family communication.

"A contract with your child is great, and it shows the parent and the child that there are consequences involved," she says.

Some teen drivers tell News 12 that they are following safety suggestions, such as locking their phone in the glovebox.

AAA says those rules will save lives, especially if adults set a good example.

"Parents really need to be modeling good behavior," Sinclair says.
