More than 1.6 million vehicles were inspected for legal weight limits in the first half of 2025, with over 400,000 found to be overloaded.
A Ministry of Public Works and Transport report on enforcement activities during the first half of 2025 revealed that a total of 1,626,333 trucks were inspected. Of these, 404,206 were found to be carrying loads beyond the legal limit — equivalent to 24.85% of all inspected vehicles.Among the overloaded trucks 403,425 were carrying less than 5% over the limit, 290 were overloaded by between 5% and 10%, 336 were between 10% and 20% over the limit, and 155 exceeded the limit by more than 20%.
Violators were fined based on both overall load and axle weight, under Articles 26 and 60 of the Road Law.
The findings were presented during a July 7 meeting to summarise the work of the Inter-Ministerial Oversight Committee on overloaded freight vehicles.
The meeting was chaired by Seng Chhuon, transport ministry secretary of state, with undersecretaries of state, working group members, mobile inspection teams and the heads of weigh stations across the country in attendance.
Chhuon praised officials for their efforts and encouraged continued tightening of enforcement to combat weight limit violations more effectively.
The meeting also discussed strategies for the second half of the year, include the establishment of weigh stations along key national roads where none currently exist, and modernising the existing stations with newer technology.
He instructed station officials to remain diligent, follow the guidance of transport minister Peng Ponea, and uphold ethical standards, discipline, unity and strict legal compliance.
To further strengthen the inspection regime, the ministry is also currently reviewing personnel assignments at weigh stations across the country.
In 2024, the ministry registered a total of 373,069 vehicles, including 317,712 motorcycles and 55,357 vehicles. It also registered 30,371 vehicles with special or personalised license plates, generating about $18.5 million in revenue.
