LATCH (Lower Anchors and Tethers for CHildren) usability in school buses and passenger vehicles.

Objective: The present study was designed to assess LATCH (Lower Anchors and Tethers for CHildren) usability in both cars and school buses. Despite being designed to make child restraint system (CRS) installation in vehicles easier and with fewer opportunities for misuse, there have been reports that LATCH is not as easy to use, or as effective, as hoped. To date, there have been few systematic or experimental studies evaluating LATCH usability.
