KENNEWICK, Wash.- A new study shows that Washington's graduated driver's license law is saving lives.
The study shows that teen driving deaths are down by about 45% since the law took effect in 2001.
1,700 teen accidents were reported last year, and less than 1,000 have been reported so far this year.
Police are attributing the recent drop to parents helping them enforce the rules.
"Especially during the first year of so when we'd stop kids who had a restricted license, and they had other teens in the car with them. When we'd contact their parents, parents had no idea that they were in violation of the law," said Kennewick Police Sergeant Ken Lattin.
The law doesn't allow new drivers to have non-family member teens in their car for the first six month, or drive between one and six in the morning.
