Mexico to require Speed Limiters on double trailer combinations

Mexico and the SCT, Mexico’s equivalent of the FMCSA has for the past couple of years, been working to pass rules and legislation prohibiting the movement of double trailers on Mexico’s federal highway system. As in the US, Mexican business interests have been pushing back hard to prevent this from happening.

Double combination vehicles are generally two 48 foot trailers with an allowed gross weight exceeding 160,000 pounds.

Due to the lack of success and to reduce the number of accidents involving double trailers, it will be mandatory to install a mechanical system, a governor that prevents vehicles from traveling at more than 80 kilometers per hour (50 mph), according to the undersecretary of Transport of the Ministry of Communications and Transport (SCT), Yuriria Mascott.

In an interview Mascott said that we have the conclusions of the committee on weights and dimensions organized by the Senate of the Republic and agreed to the immediate implementation of some measures.

One of them is the speed limiter requirement, and the other agreed was the building of more weigh and inspection stations, including the placement of electronic measurement arches on federal highways to assure compliance with the weights and dimensions for the motor carriers.
The undersecretary said that public-private partnership financing schemes are being analyzed for the installation of weighing arches.

On the other hand, he commented that because drivers are involved in 80 percent of the causes of accidents, they analyze measures such as creating a fatigue rule that prevents motorway operators from being in front of the wheel more time than recommended to be In concentration.

The driver’s psycho-physical state will also be reviewed and driver certification, loading processes and dispatch processes will be implemented.

Before people start saying “I told you so”, the 80% is a relative number. Accidents involving these double trailers are usually found to be the fault of the automobile involved as was the case in 2013 with the propane tanker accident outside of Mexico City.
