On Monday, August 10, 2026, the Argentine government officially published Decree 689/2026, a landmark update to the country's heavy transport regulations. The decree, signed by President Javier Milei, Economy Minister Luis Caputo, and Cabinet Chief Diego Santilli, modernizes Annex R of Decree 779/95, which regulates the Traffic Law and defines the weights and dimensions of heavy vehicles in Argentina.
The announcement was made by Federico Sturzenegger, Minister of Deregulation and State Transformation, who explained on his X account that the main goal is to "streamline and reduce costs of land transport", a vital sector for the country's economy. The update addresses three key areas:
1. Alignment with Brazil
Argentine truck dimensions will now be aligned with those of Brazil, Argentina's main Mercosur trading partner. While a full integration of the vehicle fleets of both countries still requires adjusting Mercosur regulations, the government sees this as a necessary step to facilitate bilateral trade and reduce cross-border logistics friction.
2. Increased Allowed Weights
The maximum permitted weight per truck has been increased, while always respecting the weight per axle, which is the critical factor for road maintenance. Sturzenegger called it an "absurdity" that trucks capable of carrying more cargo were prevented from doing so by an outdated rule. This change is expected to improve efficiency and lower the cost per ton transported.
3. Adaptation to New Technologies
The regulation now accommodates vehicles powered by alternative fuels (gas and electricity), whose technology has changed dramatically over the past three decades. This allows for modern configurations that were previously not contemplated, supporting the transition to cleaner and more efficient transport.
Key Officials Behind the Measure
Sturzenegger specifically thanked Secretary of Transport Mariano Plencovich and Director of National Highways Marcelo Campoy. He also acknowledged the team at the Ministry of Deregulation: Secretary of Transformation Maximiliano Fariña, Undersecretary of Deregulation Héctor Huici, Cecilia Domínguez, and Santiago Franco. Additionally, he highlighted the work of the Legal and Technical Secretariat, led by María Ibarzabal.
Reactions and Context
The measure has sparked mixed reactions on social media. Some users expressed concern about road conditions, with one user, Hermanos Macanas, writing: "They authorize more weight on trucks and don't fix the roads. What could go wrong, right?" Others, like Luis Mario ll and J.U., offered critical comments about the government's management.
Decree 689/2026 is part of the economic deregulation plan promoted by President Milei's administration, which aims to reduce logistics costs and improve the competitiveness of Argentina's productive sector. The update of Annex R was a long-standing demand from the transport industry, which had been constrained by regulations written in 1995, when vehicle fleets and technologies were vastly different.
With this reform, the executive branch expects a positive impact on transport costs, which could eventually translate into lower final prices for consumers, in a context where fighting inflation remains a top priority.
