Frequently asked questions
Does Hoy No Circula now apply in the Toluca valley?
Yes. From January 1, 2026, Hoy No Circula sanctions apply in the Toluca and Santiago Tianguistenco valleys. Driving on your restricted day results in a fine of 20 UMA (approximately MXN 2,200). Late vehicle verification costs 30 UMA, and exceeding emission limits detected by remote sensors incurs a 24 UMA fine plus possible license plate confiscation.
How do I know if my vehicle is exempt from Hoy No Circula?
Your vehicle receives a hologram sticker after emission testing: Double Zero (00) and Zero (0) holograms are exempt from all restrictions. To qualify for an Exempt hologram, your vehicle must be no more than 8 years old and pass emission testing. Emergency vehicles, school transport, disability vehicles, and public service vehicles are also exempt.
What safety features are mandatory in new cars sold in Mexico?
All new light vehicles must comply with international safety standards including three-point seat belts, headrests, mirror systems, ABS braking, and front airbags. Mexico has been updating its NOM standards to close the safety gap with the US and EU.
Do all Mexican states follow the same traffic laws now?
Mexico's 2022 General Law on Mobility and Road Safety establishes a national framework, but implementation varies by state. The law mandates child restraint systems, drink-driving enforcement, helmet use, seat belt compliance, and speed management across the country. States are gradually updating local regulations to align with the national law.
