In New Mexico, which occupants of a car are required to wear seat belts or suitable child restraints?

New Mexico law requires every occupant of a vehicle to wear a seat belt or suitable child restraint. Seat belts have been proven to save lives and reduce injuries – even in the rear seat. A study conducted in 2015 by the Insurance Institute for Highway Safety and the Children's Hospital of Philadephia found that unrestrained rear-seat occupants were nearly eight times as likely to sustain a serious injury in a crash as restrained rear-seat occupants.
