Recently, automobile laws in several states have changed to require
front seat passengers to be both over 60 pounds and over 12 years of
age. Like many people, you may be skeptical of the necessity of these
laws. What you should realize is that automobile engineering has
improved, and front seat airbags have changed. While they have
become safer and more effective, they have made it necessary for
younger children to remain in the backseat. When drivers like you
understand the reasons for this change, everyone will surely
appreciate that it is for the safety of their children.
