Teen crash rates affected by sleep

If it's a struggle for your child to get to school by 7:30 a.m. or 8 a.m. in the morning, a new study shows getting a later start could get them more rest and save lives.Schools in one Kansas County gave kids the extra hour.

University of Kentucky researchers followed up and found more kids reported getting eight hours of sleep on school nights instead of the usual seven.

And teen car crash rates declined 16.5 percent in the two years after the change. Elsewhere, teen crash rates increased nearly 8 percent.
