Safety Rules

General Law on Mobility and Road Safety Implementation

Effective January 1, 2026

  • High Impact
  • On Theory Test

Before

Fragmented state-level rules

Road safety laws varied significantly between states with no national framework for child restraints, helmet use, or speed management

National safety framework

Continued implementation of 2022 national law mandating child restraint systems, drink-driving enforcement, universal helmet use, seat belt compliance, and speed management aligned with WHO best practices

Official Source: Ley General de Movilidad y Seguridad Vial

Instructor's Tip
Mexico's 2022 General Law on Mobility and Road Safety is being enforced more broadly across states. Key requirements include proper child restraint systems, zero-tolerance for drink-driving, mandatory helmet use for motorcyclists, and universal seat belt compliance. States are updating local laws to align with the national framework.

Environmental Zones

Stricter Vehicle Emission Verification

Effective January 1, 2026

  • Medium Impact
  • On Theory Test

Before

Biannual verification for some

Emission verification schedules varied by state and vehicle age

After (2026)

Hologram-based restriction system

Vehicles classified by emission hologram (00, 0, 1, 2, Exempt); only vehicles up to 8 years old with passing emissions can get Exempt hologram; remote sensors detect violators on the road

Official Source: SEDEMA Verificación Vehicular

Instructor's Tip
Your vehicle's hologram sticker determines when you can drive. Double Zero (00) and Zero (0) holograms are exempt from Hoy No Circula restrictions. To get an Exempt hologram, your vehicle must be no more than 8 years old and pass emission testing. Remote sensors on roads now detect vehicles exceeding emission limits.

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.
