Mexico has officially updated its federal traffic regulations to allow for the use of electronic devices, such as speed cameras and radars, to issue speeding fines. The change follows a decree published in the Official Gazette of the Federation (DOF) on August 13, which officially took effect on August 14.

The new measure specifically applies to federal highways and bridges. It is important to note that these regulations do not alter traffic laws for city streets or local avenues, which remain under municipal jurisdiction.

Under the revised regulations, infractions regarding exceeded speed limits "may be imposed through the detection of electronic devices." While this provides the legal framework for automated enforcement on federal roads, the decree does not mandate the immediate installation of these devices across the entire national highway network. Instead, it authorizes the National Guard to utilize "suitable technical instruments" to monitor and penalize violations.

The regulations establish six categories of fines based on vehicle type and the magnitude of the speed violation. Starting in May 2026, the daily quota for calculating these fines will be based on one Unit of Measure and Update (UMA). For instance, drivers of automobiles, vans, or motorcycles without a trailer who exceed the speed limit by up to 20 km/h may face fines ranging from 2,932.75 to 3,519.30 pesos. If the excess exceeds 20 km/h, the fine can reach up to 4,105.85 pesos.

Furthermore, the reform introduces a transparency measure through Article 205 Bis. This requires National Guard personnel to upload information regarding issued infractions to the agency’s official website within 72 hours of the violation.
