Transporting an excavator, transformer, crane, wind turbine component, bridge beam, or other oversized cargo on Kenyan roads requires more than just a capable truck. If your cargo exceeds the legal weight or dimensions allowed on public roads, you must first obtain an Abnormal Load Permit from the Kenya National Highways Authority (KeNHA).
Failing to secure the required permit can lead to delays, prosecution, fines, and possible damage claims if road infrastructure is affected. This guide explains who needs an abnormal load permit, the application process, permit fees, and the expected approval timeline.
What Is an Abnormal Load Permit?
An abnormal load permit is an official authorization issued by KeNHA allowing a transporter to move cargo that exceeds Kenya's normal legal limits for vehicle weight or dimensions.
These permits help ensure that oversized cargo can travel safely without endangering road users or damaging bridges, highways, culverts, and other public infrastructure.
When Do You Need One?
You should apply for an abnormal load permit if you are transporting cargo such as:
- Excavators
- Bulldozers
- Cranes
- Transformers
- Large generators
- Wind turbine components
- Steel bridge beams
- Industrial machinery
- Oversized construction equipment
Generally, any load exceeding the legal limits for weight, width, height, or overall length requires approval before travelling on public roads.
Requirements for an Abnormal Load Permit
KeNHA requires applicants to provide sufficient information to demonstrate that the proposed journey can be completed safely.
Depending on the nature of the load, the application may require:
- A completed permit application.
- Details of the vehicle and cargo.
- A route survey identifying bridges, overhead structures, and other obstacles.
- A proposed travel schedule.
- Police or owner escorts where required.
- Warning lights and safety markings on the vehicle.
- Public notice in a national newspaper for certain exceptionally large movements.
- Any additional information requested by KeNHA to protect road infrastructure and public safety.
How Long Does Approval Take?
According to KeNHA's Service Delivery Charter, applications for an axle load exemption or abnormal load permit are processed within two working days, provided all the required documentation has been submitted correctly.
Incomplete applications may take longer while additional information is requested.
Abnormal Load Permit Fees
Permit charges vary depending on the size and weight of the cargo.
| Description | Permit Fee (KSh) |
| Oversize load up to 25,000 kg | 5,000 |
| Oversize load above 25,000 kg up to 50,000 kg | 10,000 |
| Oversize load above 50,000 kg | 250,000 |
| Width exceeding 2.65 metres | 5,000 |
| Height exceeding 4.20 metres | 10,000 |
| Rigid vehicle length exceeding 12.5 metres | 15,000 |
| Articulated vehicle exceeding 17.4 metres | 20,000 |
| Vehicle combination exceeding 22 metres | 25,000 |
These are permit charges for authorized abnormal load movements and should not be confused with penalties for illegally overloading a vehicle.
Important Conditions After Approval
Receiving an abnormal load permit does not exempt a vehicle from compliance with other road regulations.
Transporters must:
- Carry the permit throughout the journey.
- Follow the approved route.
- Observe the specified travel schedule.
- Use escorts where required.
- Display warning lights and safety signs.
- Present the vehicle for weighing when directed at a weighbridge.
Failure to comply with the permit conditions may result in enforcement action.
Tips Before Applying
To improve your chances of quick approval:
- Measure your cargo accurately before applying.
- Confirm the total vehicle weight and axle configuration.
- Plan the safest route in advance.
- Check for low bridges, overhead power lines, and narrow sections of road.
- Submit all required documents at the same time to avoid delays.
Good planning helps reduce transport interruptions and protects valuable cargo.
