Impact of child restraint policies on child occupant fatalities and injuries in Chile and its regions: An interrupted time-series study

In the short term, the CRL and the National Decree were associated with fewer child occupant fatalities, at the national level and in the southern regions, and severely injured child occupants in traffic collisions in Chile's northern regions. These results demonstrate a limited temporal and territorial impact. This suggests that to effectively protect vulnerable populations across all territories, efforts should be expanded more consistently and sustained over time.
