Answer 1

Starting in the 2006 model year, all passenger cars and light-duty trucks must be equipped with sensors that identify children and very small adults and deploy the airbag with less force or not at all.

This doesn't mean it's OK for kids to ride up front, but it does mean fewer risks for adults of short stature. Some automakers are taking things a step further by designing airbag systems that not only change the force that the airbag deploys, but also the size and shape of the airbag.

These technology advances are all part of an effort to improve airbag safety and benefits.
