Background
MPWT operates specialized roadside inspection teams to verify compliance with vehicle weight limits and to protect the structural integrity of national roads. MPWT deploys special inspection teams to verify compliance with statutory vehicle weight limits on national roads.
Axle load and gross vehicle weight standards are used to manage pavement loading and bridge safety and to extend service life of road infrastructure. A provincial MPWT-led task force carried out a roadside inspection on National Road 64 at km76 in Kulean district, Preah Vihear on 30 May 2026.
Key Developments
On 30 May 2026, a special inspection team under MPWT conducted enforcement checks on heavy transport vehicles along National Road 64 in Preah Vihear province. The operation targeted vehicles suspected of carrying loads above permitted limits at km76 in Kulean district.
Enforcement Actions
The task force inspected a total of three heavy transport vehicles during the operation. Two vehicles were recorded carrying excess loads of 15 tonnes each, and one vehicle was recorded carrying an excess load of 20 tonnes.
Operational Implications
Recorded overloads of 15–20 tonnes represent substantial excess gross weight that increases pavement stress and can accelerate road surface and bridge deterioration. Systematic roadside weight checks supply objective data on compliance levels that are relevant for infrastructure maintenance planning and transport safety assessments.
