A new study says tougher restrictions on Iowa's teenage drivers could have saved the lives of 32 young drivers in 2009.
The study report issued Tuesday includes suggested standards:
requiring drivers to be 16 before earning a learner's permit and restricting passengers to no more than one non-family passenger
under 21 unless a licensed driver older than 21 is in the vehicle.
Teen driving deaths are falling nationally but have remained flat or grown slightly among 16- to 18-year-old drivers in Iowa.
Iowa has a graduated driver's licensing program, but it's not as strict as programs in some other states.
The study was released by the Allstate Foundation, a nonprofit arm of insurance giant Allstate.
