Smart weighbridge cuts corruption, boosts compliance

Kenya's efforts to protect its highways from overloaded trucks are increasingly being driven by technology, with a digital enforcement system at the Mariakani Weighbridge delivering a 98.5 per cent compliance rate while significantly reducing opportunities for corruption through automated monitoring and electronic penalty processing.

The transformation has seen weighbridge operators embrace an integrated digital platform that screens vehicles before they reach inspection points, automatically generates penalties through the government's eCitizen platform and transmits enforcement data to a central management system at the Kenya National Highways Authority (KeNHA) headquarters in Nairobi.

At the same time, operators have broadened collaboration beyond enforcement agencies by bringing together the Judiciary, the Kenya Transporters Association, the Kenya Association of Manufacturers (KAM) and other stakeholders to promote voluntary compliance with axle load regulations.

George Ngugi, Operations Manager in charge of the Mariakani Cluster in Mombasa County, said KeNHA had directed Ebenezer Commercial Works, the firm contracted to operate weighbridges in Mombasa and Kilifi counties, to work closely with industry players to improve compliance while ensuring smooth operations.

"KeNHA has firmly instructed us to ensure smooth operations by working closely with industry players. We have been doing that religiously," Ngugi said.

The Mariakani cluster, one of Kenya's busiest freight inspection points, handles more than 8,000 heavy commercial trucks every day.

Managed by Ebenezer Commercial Works on behalf of KeNHA, it oversees both the static weighbridge and mobile enforcement units across approximately 1,466 kilometres of roads in the Coast region.

Ngugi said sustained engagement with transporters, manufacturers and other players had contributed to the station recording a compliance rate of about 98.5 per cent, with authorities targeting even higher levels through continued stakeholder engagement.

Central to the reforms is a High-Speed Weigh-in-Motion (WiM) system that weighs every truck while it is still moving, replacing the heavily manual processes that previously characterized axle load enforcement.

"The first point of weighing is the high-speed motion before you get to the static. Before you get to the static, you have already been weighed," Ngugi explained.

Vehicles flagged for possible overloading are automatically directed to the static weighbridge for verification, minimizing opportunities for drivers to bypass inspections or influence the enforcement process.

Officials say one of the most significant reforms has been integrating weighbridge operations with the government's eCitizen platform, where penalties are processed automatically whenever an overloaded truck is detected.

"The moment we detect an overload, we create an invoice through eCitizen. All the information remains in the system," he said.

He noted that the digital trail has significantly strengthened accountability by ensuring every enforcement action is electronically recorded.

"Even if somebody tries to interfere with the physical process, the system still retains all the information for auditing," he added.

The anti-corruption safeguards extend beyond Mariakani. Every weighbridge in the country is linked to a centralized management system at KeNHA headquarters, allowing officials to monitor enforcement activities and vehicle data in real time.

"All weighbridges are integrated with management systems. The system sits at KeNHA headquarters, so there is no way to bypass all that," Ngugi said.

The centralized oversight has made it considerably more difficult for local officers to manipulate records or alter enforcement decisions without detection, reinforcing transparency across Kenya's axle load management system.

Authorities say the digital transformation is not only improving compliance but also safeguarding billions of shillings invested in the country's road infrastructure.

Excess axle loads remain among the leading causes of premature road deterioration, increasing maintenance costs and shortening the lifespan of highways.

With freight volumes continuing to rise along the Northern Corridor, officials believe technology-driven enforcement, backed by collaboration between regulators, transporters, manufacturers and the Judiciary, will play a critical role in protecting Kenya's roads while ensuring fair, transparent and corruption-free enforcement of axle load regulations.
