The Kanyonyoo weighbridge in Kitui County is playing a key role in protecting roads from premature damage by enforcing vehicle load limits and ensuring compliance with transport regulations.
Located in Yatta/Kwa Vonza Ward, Kitui Rural Constituency, along the Garissa–Kitui–Nairobi Highway, the facility was constructed by the Kenya National Highways Authority (KeNHA) to regulate the weight and dimensions of heavy vehicles, helping to prevent overloading and safeguard road infrastructure.
The weighbridge became operational in February 2025 following the completion of construction and installation of the necessary equipment.
Speaking during an investigative interview, the station manager, Faith Njani, said the facility had recorded improved compliance among motorists and transporters since operations began, with the majority of vehicles meeting the prescribed axle-load and dimensional requirements.
Njani said the station weighs approximately 1,500 vehicles daily, with only between two and four trucks typically found exceeding the stipulated weight or dimensional limits and subjected to enforcement measures. “Since we started operations at Kanyonyoo weighbridge, we have witnessed improved compliance among members of the community and transporters who understand the procedures carried out at the station. We weigh approximately 1,500 vehicles a day, and only about two to four trucks are found overloaded or exceeding the required dimensions,” she said.
She added that the high compliance rate demonstrated growing awareness among transporters of the importance of protecting roads through adherence to the law.
Beyond preserving road infrastructure, the facility has also contributed to improved security in the surrounding area and created employment opportunities for local residents.
According to Njani, the station’s daily operations have enhanced surveillance of cargo in transit, making it easier to identify suspicious movements and support efforts to curb the transportation of illegal goods.“We have also witnessed improved security since the weighbridge began operating. In addition, the facility has helped many local residents secure jobs to support their livelihoods,” she said.
The station has also helped promote fairness among businesspeople involved in transporting heavy goods by ensuring that vehicles operate within the legally prescribed load limits.
Njani said enforcing uniform standards was essential in creating a level playing field for businesses, preventing some transporters from gaining an unfair advantage by carrying excessive loads.“There is equality among those engaged in businesses involving heavy goods because they are required to transport loads within the limits set by the law. This promotes fairness in the market,” she said.
The facility uses digital weighing equipment to determine vehicle and axle loads, assess weight distribution and identify violations of the prescribed limits.
Njani said the equipment undergoes quarterly calibration to maintain accuracy and ensure that vehicles are weighed transparently.“We weigh trucks and other vehicles transparently, allowing drivers to understand the weight they are carrying. The machines are calibrated quarterly to ensure accuracy and prevent under-weighing or over-weighing,” she said.
Vehicles found to be compliant with the applicable axle-load limits are cleared to continue with their journeys, while those found in violation of the prescribed limits are directed to a holding area for further action in accordance with the law.“Any vehicle found exceeding the prescribed load limits is detained, and the violation is recorded pending the necessary enforcement action,” Njani said.
In addition to monitoring axle loads, the station is mandated to inspect vehicles transporting abnormal loads to ensure they comply with the legally prescribed dimensions.
The inspections are intended to protect roads and other infrastructure along transport corridors from damage caused by oversized or improperly secured cargo.
However, Njani identified non-compliance by some transporters as a major challenge facing the station, saying certain drivers deliberately avoid weighing their vehicles despite knowing they may be overloaded.
She further claimed that some transporters mobilise groups of people to intimidate or attack weighbridge staff while they are carrying out their duties, posing a threat to personnel and disrupting operations.“We have a challenge with transporters who are unwilling to have their vehicles weighed. Some fail to stop when they know they are overloaded. In other cases, they mobilise goons to attack the station and our teams during operations,” she said.
Njani appealed to members of the public to support enforcement efforts by reporting individuals involved in intimidation and deliberate evasion of the law.
She maintained that cooperation among transporters, motorists, local residents and enforcement agencies remained critical to ensuring that the weighbridge achieves its objective of protecting roads, promoting road safety and supporting the sustainable use of public infrastructure.
