Mexico City — President Claudia Sheinbaum has issued a decree reforming the Federal Highway and Bridge Traffic Regulations, published in the Official Gazette of the Federation on May 25, 2026. The new rules strengthen public safety and grant full enforcement authority to the Mexican Army through the National Guard.
Drivers on federal highways must now meet strict mechanical and safety standards. Non-compliance can result in fines calculated in UMA (Measurement and Update Units) and even vehicle impoundment.
Key Requirements for Drivers
- Brakes in optimal condition: The National Guard will actively inspect braking systems. According to Article 42, traffic accidents caused by brake failure will result in severe fines.
- Tires and spare: Vehicles must have tires that ensure grip even on wet pavement. Article 50 requires a properly inflated spare tire in good condition, except for motorcycles and bicycles.
- Valid documentation: Drivers must present the original vehicle registration card when requested. Vehicles must display current license plates and registration stickers. In case of theft or loss, a police report must be shown to avoid federal fines.
- Full obedience to authorities: Drivers must follow all orders and signals from National Guard officers, even if they contradict traffic lights or other devices. Violations carry fines of 40 to 50 times the daily UMA rate.
- Warning devices: Article 45 requires a horn audible from 60 meters, with no modifications from the factory setting. In case of mechanical failure, drivers must use parking lights and fluorescent triangles on the shoulder. Ignoring this carries a fine of 10 to 20 daily UMA fees.
- Emissions control: Engines must meet official emissions standards. The National Guard will help verify that vehicles do not exceed permitted limits.
- Mandatory sobriety tests: Drivers must submit to alcohol or drug detection tests when requested by authorities. Refusal results in immediate sanctions and possible arrest.
The regulations apply to all federal highways and bridges under federal jurisdiction. Authorities urge drivers to perform regular maintenance and carry all required documents to avoid penalties.
