The road signs used in Mexico are regulated by Secretaría de Infraestructura, Comunicaciones y Transportes's Directorate-General for Roads (Dirección General de Carreteras), and uniformized under a NOM standard[1] and the Manual de Señalización y Dispositivos para el Control del Tránsito en Calles y Carreteras (Manual of Signage and Traffic Control Devices for Streets and Highways),[2] which serves as a similar role to the MUTCD developed by the Federal Highway Administration. The signs share many similarities with those used in the United States and Canada. Like Canada but unlike the United States, Mexico has a heavier reliance on symbols than text legends.[3]
Before the eventual promulgation of an updated federal NOM standard in 2023,[1] with a comprehensive catalog of signs for use in urban contexts—absent in previous norms[note 1]—, signage varied greatly across states;[4][note 2] for instance, the state of Jalisco applied its own sign standard to state highways that is based on the 2011 NOM standard, whose signs were largely identical to those designed for the 1986 Manual de Dispositivos. Among other things, mandatory signs are circular, as in the European and some South American countries but unlike in the federal NOM standard.[5]
