What I'm looking for:
- How many restrained children between the ages of 4-8 were injured in car accidents (both seat belts and car seats)
- How many restrained children between the ages of 4-8 were injured in car accidents in ways directly attributed to seat belts.
- How many restrained children between the ages of 4-8 were in car accidents and not injured (restrained by seatbelts and also car seats)
- Injury rates at different car speeds
- As a control, the injury rates of adults sitting in the back seats of cars that were properly restrained.
If you believe the surveys done by CHOP, state laws are how most parents decide how to restrain their children. That is, many parents believe that it is safe and preferred to use just a seat belt on a child over the age of 4 if the state does not mandate otherwise. I guess in that case the law is a good idea, I just wish they made more provisions for emergencies.
