FMVSS 213 Outline by Safe Ride News Publications

This color-coded outline was created to help understand FMVSS 213, the regulation that sets standards for car seats.  It also can function like a table of contents for users who are wanting to track down specific details within the official NHTSA document.  (NOTE:  SRN will update this outline to reflect FMVSS 213a when that standard becomes mandatory in 2025.)
