Overview of NOM-012 weights and measures regulations for Mexico what they mean and how telematics can help fleets comply
Published on October 1, 2018
What do I need to know?
Against a backdrop of opposition, Mexico moves forward with new trucking regulations in an effort to decrease truck-involved accidents and relieve traffic congestion.
NOM-012 governs the weights and dimensions of Heavy-Duty trucks travelling on roads and highways, and sets specific requirements for double-articulated trailers, called “fulles” in Mexico [1,2]. The changes require double-trailers to undergo certification, or “express authorization,” to operate and must be equipped with safety features like GPS and speed governors. The law went into effect in early
July 2018 and is now being enforced.
At the same time, new Hours of Service (HOS) regulations have been published which set the standards for driving time and breaks . For the first time in Mexico, drivers of commercial motor vehicles will be required to carry HOS logs, either in printed or electronic format. The regulations are set out in NOM-087.
Key requirements for double-trailers
With the latest additions, here is an overview of some of the regulations in NOM-012 and how they affect double- trailer tractors:
GPS: Trucks must now be equipped with GPS tracking. These devices must be able to report position and speed, at a minimum. The data must have a backup system, and the data must be made available to the Secretariat and the Federal Police, as requested. Speed data may be used to confirm compliance with laws.
Truck Dimensions: Not including mirrors and accessories, the maximum width is 2.60 meters, and the maximum height is 4.25 meters (length specifications are also specified depending on the road type).
Driving Parameters: Drivers must stay in the far right lane, except in cases of overflow, and they must keep at least 100 meters behind other Heavy-Duty vehicles.
Holidays: The Secretariat may define and publish additional security measures around holiday periods that sustain large amounts of vehicle traffic.
Curvy Roads: Drivers must pull over/stopon winding roads to allow for the circulation of traffic.
ABS: Trucks must have anti-lock brakes and an automatic brake adjustment system.
Safety Equipment: Trucks must be equipped with speed governors to keep them under 80 kilometers per hour, as well as have daytime running lights and auxiliary mirrors.
Certification and enforcement
To lawfully operate on federal roads, all double-trailers must complete a registration process with the Ministry of Communications and Transportation (SCT, Spanish acronym) and obtain an “express authorization” for each trailer. The law applies to domestic and imported trucks. The certification is free; however, it now requires the physical verification of all compliance checks, including length of truck, mirrors, driving logs, and GPS . It’s important to note that the express authorization does not replace the motor carrier permit.
To request authorization for double-articulated trailer tractors, fleets can start the three-step process via the SCT website . As of July 2018, the SCT has released more than 106,000 requests for express authorization of double- articulated vehicles .
According to the regulatory text, the SCT — via the Federal Police — is coordinating verifications at fixed centers. The SCT may grant self-regulation to carriers with onsite electronic weighing and scaling capabilities. An application for self-regulation must outline every stage of the loading process, as well as how internal monitoring is enforced to ensure that all shipments comply. The SCT may also do on-site inspections before granting self-regulation.
Once operators receive express authorization, they can travel with double-trailers on Type “ET” and “A” roads, though exceptions are available for roads of lower classifications but required a separate “connectivity authorization” from the SCT.
Few exemptions are outlined for express authorization and seem mostly limited to tow vehicles. Other specialty equipment may also be exempt, but it still must be indicated in the record of weight and dimensions and designated as a special vehicle with a specific design. Other vehicles that do not meet the standards will not be allowed for import or transit on government roads.
Enforcement and penalty for non-compliance
Ongoing enforcement will continue via the Federal Police, especially when it comes to enforcing regulations such as maximum speed, daytime running lights and distance between trucks. Federal Police may also do random verifications on the road, including for fleets that are self-regulating. If a fleet has been granted self-regulation, but is then found three times within a single year to violate the standards, then the self-regulation license will be suspended and a fine issued.
Trucks that do not comply may be fined, and if the fine goes unpaid, the truck will be taken off the road and cargo must be switched to a single tractor/trailer, or to a compliant double-trailer tractor.
Due to a backlog, the SCT stated that full enforcement and issuance of all express authorizations could take until the end of 2018 .
Note: The enforcement period for trucks operating with lights on at all times (it must be an electronic function that automatically turns the lights on) begin later on January 1, 2019.
Objectives of NOM-012
Safety. The primary purpose of the changes to NOM-012 is to support road safety and decrease vehicle accidents, and ultimately, to remove unsafe trucks from the road. The changes also setup and help spark fleet connectivity in Mexico with the requirement of GPS installed. While items like GPS were encouraged in previous versions of the law, this latest version explicitly requires it.
When industry stakeholders and the SCT began reviewing NOM-012 and its 2014 version, it cited two main purposes for seeking changes :
- [translated] “to encourage motor carriers to operate at all times with greater safety conditions, and second, to obtain a real sampling of the conditions in which they operate in the federal highways.”
- The second purpose also included examining levels of security on federal roads, such as being able to monitor and check driver speed via GPS, in an attempt to reduce the number of collisions that involve heavy-duty trucks.
Double-trailer safety concerns
Double-trailer trucks have long received criticism in Mexico. A safety activist who lost his son in a collision with a double-trailer truck claims that there are an average of 1,600 fatal accidents involving double-trailers every year . His goal is to ban the trucks altogether. However, industry advocates and government officials say that this number is far less, with double-trailer trucks accounting for less than 3 percent of fatal accidents in Mexico .
Others in the industry have also pointed to insufficient regulations or poor implementation and enforcement of trucking regulations as the cause of safety issues, particularly related to speeding or driver licensing .
Double-trailer trucks have also undergone the same scrutiny and concern for safety in the U.S . The debate is sure to continue.
Examining the impact of NOM-012 regulations
NOM-012 will have a significant impact on the trucking industry in Mexico. The following is a summary of some of the reported potential effects.
Demonstrations have been held in protest to the law. One demonstration, which occurred within days of the start of enforcement, involved 612 cargo units stopped at the Port of Altamira to peacefully protest fines. Some trucking industry stakeholders have asked the government to extend the deadline [3,15].

Its primary purpose is to verify that any telecom device has the authorization to connect to the Mexican Telecom Network.
Now in effect, NOM-012 exemplifies Mexico’s desire to lower the rate of truck-involved accidents and reduce traffic congestion. With the primary goal of increasing road safety, NOM-012 explicitly sets weight and dimension requirements for Heavy-Duty trucks as well as GPS, safety equipment, and ABS enforcement, amongst other requirements for double-articulated trailers. Those responsible for their fleet operations must obtain “express authorization” to legally drive their trucks. Though NOM-012 poses some challenges for operators, compliance is necessary to maintain productivity, avoid fines, and support road safety.
