Lithuania Deploys Automatic ‘Weight Cameras’ to Protect Highway Network

One in four heavy goods vehicles (HGVs) travelling on Lithuanian roads is currently operating over the legal weight limit. This statistic, revealed by the national road infrastructure company ‘Via Lietuva’, has prompted a significant shift in how the country enforces transport regulations. Moving away from traditional static weighing stations, the Baltic nation is investing in a network of high-precision dynamic weighing systems that function similarly to speed cameras.

Recent data from 2024 indicates that approximately 25% of freight vehicles violate either total mass or axle load limits. In extreme cases, vehicles have been recorded carrying double the permitted weight. This level of non-compliance causes exponential damage to road surfaces, leading to increased maintenance costs that ultimately fall on taxpayers and legitimate businesses. To combat this, the Lithuanian Ministry of Transport has launched a major procurement for six ‘Weigh-In-Motion’ (WIM) systems, with a total of 18 units planned for installation over the next three years.

Automated Enforcement Without Stopping

The new systems represent a technological leap in road policing. Unlike traditional methods that require a vehicle to be diverted to a static scale, these dynamic scales are embedded directly into the road surface. They are designed to weigh vehicles as they pass at normal highway speeds, identifying violators in real-time without disrupting the flow of traffic.

According to Transport Minister Juras Taminskas, these systems will operate with the same automation as speed cameras. Once a violation is detected, the system will automatically record the offence, allowing for immediate accountability. The goal is to eliminate the ‘culture of impunity’ that has surrounded overloaded transport, which not only damages infrastructure but also creates unfair competition for hauliers who adhere to the rules.

Strategic Rollout and Technical Standards

To ensure the data is legally robust for automatic fining, ‘Via Lietuva’ is requiring the systems to meet the highest accuracy standards. Specifically, the hardware must comply with the A(5) accuracy class under the international COST 323 recommendations. This level of precision is necessary for the automated issuance of penalties for weight violations.

The initial phase of the rollout focuses on the country’s most critical transit corridors, including the A1, which connects the capital, Vilnius, with the port city of Klaipėda.

Currently, only two such systems are operational in the country. The expansion plan aims to have the first six new units active by the end of the third quarter of 2025, following a contract signing scheduled for later this year.

The Economic and Structural Cost of Overloading

In Lithuania, standard freight vehicles are limited to a total weight of 40 tonnes. Axle loads are strictly capped at 11.5 tonnes for the driving axle and 10 tonnes for others. When these limits are exceeded, the structural integrity of the asphalt is compromised, leading to rutting and cracking far sooner than the road’s intended design life.

Martynas Gedaminskas, head of ‘Via Lietuva’, emphasizes that this is a long-term investment in economic sustainability. By identifying overloaded vehicles in real-time, the state can significantly reduce road wear and tear. This move is part of a broader national initiative titled “STOP Road Damage,” which has seen over 20 institutions, including municipalities and business associations, sign a memorandum to protect the transport network.

For international logistics companies and UK-based hauliers operating in the region, the message is clear: the transition to digital, automated enforcement means that weight compliance is no longer a matter of occasional spot checks, but a constant requirement monitored by the road itself.
