Traffic enforcement in São Paulo has focused on vehicle circulation restrictions and driver behavior. Authorities have implemented the Zona de Máxima Restrição à Circulação (ZMRC) to manage truck access in the Expanded Center, limiting large vehicles to specific hours to reduce congestion.

Regarding driver conduct, state data from early 2026 showed a high volume of fines for mobile phone use. This enforcement has been augmented by the deployment of artificial intelligence-powered cameras on the Raposo Tavares highway. The AI system has transitioned from testing to active enforcement, issuing 2,316 fines in its first month for infractions including failure to wear seatbelts and mobile phone use.

Beyond highway enforcement, the city has implemented adaptive algorithms in 1,677 traffic lights, a move that has reduced congestion by over 12%.
