The 100 deadliest days for teen drivers have begun.

Triple -A says more than 30 percent of deaths involving teen drivers happen between Memorial Day and Labor Day.

Spokesperson Adrienne Woodland say teens spend more time on the roads during odd hours when school wraps up. That leads to dangerous driving like speeding, not wearing a seatbelt, and distracted driving.

Crashes are the leading cause of death for teens ages 16 to 19.
