This document discusses safely transporting children in older vehicles that lack modern safety systems. It recommends using a child seat with a built-in harness secured by both a seat belt and top tether anchorage. This configuration provides exceptional crash protection. For older vehicles without rear seat belts, it recommends retrofitting floor-mounted 2-point belts and top tether anchorages. The document also encourages retrofitting 3-point belts and publishes guidelines for doing so. Overall, it aims to improve child safety in older cars through appropriate child restraints and retrofitting vehicles with seat belts and anchorage points.
