Notes

  • The Law states the duty for all passengers of motorised vehicles under the applicable Mexican Official Standard (NOM). It does not name front and rear seats separately.
  • Two state laws apply. The Ley de Tránsito (Art. 19 Bis) also requires a child seat in cars for children under 3 and places children under 12 in the rear seat; the Ley de Movilidad (Art. 51) sets the rule shown here.
