É claro que sua experiência pode variar, mas Tamaulipas está entre os 5 estados mexicanos (de um total de 31) listados como 'Não viaje' no Assessoria de viagem do Departamento de Estado do México em 22 de agosto de 2018:
Tamaulipas state – Level 4: Do Not Travel
Do not travel due to crime. Violent crime, such as murder, armed robbery, carjacking, kidnapping, extortion, and sexual assault, is common. Gang activity, including gun battles, is widespread. Armed criminal groups target public and private passenger buses traveling through Tamaulipas, often taking passengers hostage and demanding ransom payments. Local law enforcement has limited capability to respond to violence in many parts of the state.
