A truck can be below its advertised payload and still fail a legal or operational control. Too much mass may sit on one axle group. The cargo may move under braking. A route may impose a lower limit than the vehicle plate. The dispatch file may show a sales quantity but not the pallets, dunnage, packaging or securing equipment that also travel on the vehicle.
This guide creates one evidence-based load plan before dispatch. It does not publish one Africa-wide weight limit because national rules, vehicle configurations, roads and special-load processes differ. Primary sources were reviewed on September 25, 2026. Confirm the current road authority, vehicle plate, registration record, permit conditions and route restrictions for every trip.
Separate the five limits before loading
A dispatcher needs more than one number. The East African Community Vehicle Load Control framework distinguishes axle load, axle-group load and gross vehicle weight. Its regulations also address vehicle dimensions and special loads. Ghana Highway Authority's current weighbridge protocol separately checks gross weight and truck dimensions. These controls should not be collapsed into a single payload percentage.
| Control | Question to answer | Evidence to keep |
|---|---|---|
| Vehicle payload | How much cargo can the specific vehicle carry under its verified specification? | Vehicle plate, body or trailer record, registration and operator file |
| Gross vehicle mass | Does the loaded vehicle or combination stay within the applicable total? | Verified tare, cargo schedule and weighbridge result |
| Axle and axle-group load | Is mass distributed within each applicable axle limit? | Axle-by-axle weighing or an approved measurement record |
| Dimensions | Does the loaded vehicle comply with height, width, length and projection rules? | Measured dimensions and any required permit |
| Cargo security | Can the load remain stable through braking, turning, vibration and normal road movement? | Loading plan, securing method, equipment checks and photographs |
Use the lowest applicable constraint. A vehicle manufacturer's capacity cannot override a statutory axle limit, bridge restriction, road notice or permit condition. A legal total weight also does not prove good distribution. Heavy cargo concentrated too far forward, too far back or on one side can create an axle or stability problem while the overall total appears acceptable.
Verify the exact vehicle and route
Write the registration, tractor, trailer and body identifiers at the top of the load sheet. Record the verified tare for the actual combination, not a similar truck. Fuel, spare equipment, driver and crew, tools, pallets, bins, refrigeration equipment and securing material may affect the operational mass. If the tare evidence is old or the body configuration changed, obtain a current measurement.
Map every road authority and border on the intended route. The EAC framework applies vehicle-load controls on its regional trunk road network, while national authorities operate weighing and enforcement arrangements. ECOWAS also has a regional heavy-vehicle weight and axle-load framework, but a cross-border operator must still check how the relevant member states implement and enforce it. Record each authority page or notice with the date checked.
Identify bridges, urban restrictions, seasonal road notices, ferry limits, mine or port access rules and any abnormal-load requirement before accepting the job. A permit for one route, date or vehicle is not a general permission. If a segment cannot be verified, mark the route blocked and obtain written direction from the responsible authority or contracted carrier.
Build the cargo schedule from physical units
Start with the purchase order, packing list or warehouse release, then verify the physical cargo. Give every package group a description, quantity, unit mass, total mass, dimensions and handling note. State whether a weight is measured, taken from controlled product data or still awaiting confirmation. Do not quietly convert an estimate into a measured figure.
- Include pallets, crates, bins, stillages, wrapping, dunnage and securing equipment.
- Separate dense items that need a specific deck position from light volume cargo.
- Identify liquids, hanging loads, machinery, coils or other cargo with a special centre-of-gravity concern.
- Keep dangerous goods, temperature-controlled cargo and food controls in their own regulated workflows.
- Freeze the package count and weight schedule when the load is released to the vehicle.
The IMO/ILO/UNECE CTU Code is a non-mandatory global code for safe packing of cargo transport units used on land and sea. It emphasizes the whole packing and securing chain and warns that poor packing or securing can injure people and damage cargo or equipment. Use it as a practical reference, then apply the binding rules and competent-person requirements for the jurisdiction and cargo.
Plan distribution before the forklift starts
Create a deck plan with the cargo groups, intended positions and unloading sequence. Place the plan beside the verified vehicle geometry and axle information. The warehouse should not improvise the final arrangement from floor space alone. A visually full deck says nothing reliable about axle distribution or stability.
Keep the centre of gravity as low and controlled as the cargo permits. Avoid side-to-side imbalance. Check that concentrated loads sit on deck areas designed to support them and that the intended position does not exceed a floor, body, pallet or container limit. Confirm the effect of a trailer, lift axle or multi-drop unloading sequence on the remaining distribution.
Plan the final delivery first when the route has several stops. Removing one heavy block can change the balance of everything left on the truck. Record the permitted unloading order and require a new assessment if a customer changes quantities or stops. If the load plan depends on a specific sequence, make that constraint visible to the driver and warehouse team.
Choose and inspect the securing system
Securing must match the cargo, vehicle body and expected transport forces. Blocking, bracing, lashing, locking and containment serve different purposes. A heavy item can still slide or tip, and friction alone should not be assumed to hold it. Use rated equipment, compatible anchor points and a competent loading method.
- Inspect the deck, headboard, side structures, doors and anchor points.
- Reject damaged lashings, chains, hooks, locks, nets, bars or dunnage.
- Protect securing equipment from sharp edges and heat.
- Prevent packages from crushing, shifting or releasing during normal transport.
- Photograph the completed arrangement before curtains or doors hide it.
- Record who loaded, who checked and when the vehicle was sealed or released.
Do not turn the photographs into a substitute for calculation, inspection or trained judgment. They are traceability evidence. Loads needing engineering, dangerous-goods, lifting or abnormal-load controls should be handled under the applicable specialist procedure.
Use the weighbridge as a dispatch gate
Weighing should answer the exact compliance questions in the route plan. Where available, obtain axle or axle-group results as well as the gross result. Match the ticket to the registration, trailer and dispatch reference. Check units, date, time, station and whether the reading represents a complete vehicle combination.
The Ghana Highway Authority publishes a clear current protocol: an authorised officer directs the truck to the station, the driver submits the waybill, the truck is weighed and its dimensions are checked, and a weighing certificate is issued. If the vehicle is overloaded, the published process calls for excess cargo to be shed, the fine paid and a receipt issued. A compliant vehicle proceeds. The same protocol warns against unauthorised payments.
That Ghana process is useful as a factual workflow, not a universal rule for every country. Keep the local ticket, official receipt and correction evidence required on the actual route. If cargo is removed or rearranged, update the cargo schedule and obtain the required reweighing proof before dispatch. Never edit the original record to hide the first result.
Calculate efficiency only after compliance
The Truck Load Optimizer reports load efficiency as entered cargo weight divided by entered truck capacity. It also calculates cost per tonne-kilometre from the total trip cost, cargo tonnes and distance entered by the user. These are planning ratios, not legal conclusions or market rates.
| Planning measure | Formula | What it does not prove |
|---|---|---|
| Load efficiency | Entered cargo weight divided by entered capacity | Legal axle distribution, stability or route permission |
| Cost per tonne-kilometre | Entered total trip cost divided by cargo tonnes and distance | A quoted freight tariff, profit or full contract cost |
| Unused entered capacity | Entered capacity minus entered cargo weight | That more cargo can be safely or legally added |
Build total trip cost from evidence that fits the job: fuel, driver and crew, tolls, border and handling charges, loading time, insurance, permits, maintenance allocation, return positioning and expected waiting. Do not use a lower cost per tonne-kilometre as permission to fill remaining space. Compliance and safe distribution remain the first gate.
For related planning, reconcile fuel with the Fleet Fuel Variance Checklist, check physical package records with the Export Packing List Checklist, and prepare border documentation with the Customs Clearance Documents Guide. For packed export containers, keep the separate Container VGM workflow where it applies.
Create one dispatch packet
The driver, dispatcher and receiving team should be able to connect the load to the same trip without guessing. Keep a controlled packet in the format required by the operator and authorities.
- Vehicle, tractor, trailer and driver identifiers.
- Route, border, permit and restriction checks with verification dates.
- Verified tare, vehicle plate and registration evidence.
- Cargo schedule, package count, weights, dimensions and loading plan.
- Securing method, equipment inspection and completion photographs.
- Waybill, invoice, packing list and regulated-cargo documents where applicable.
- Weighbridge certificate, correction record, reweighing result and official receipts.
- Emergency, defect, delay and escalation contacts.
Protect commercial and personal data. Give each party only the information needed for the trip, and store the master file under the operator's retention and access rules. A dispatch record should support safety and accountability without becoming an uncontrolled copy of driver identity or customer information.

Frequently asked questions
Does truck payload capacity prove that every axle is legal?
No. Total payload, gross vehicle mass and the load carried by each axle or axle group are different controls. Verify all applicable limits for the exact vehicle, route and country.
Can AfroTools calculate a legal truck load limit?
No. The Truck Load Optimizer uses the capacity and cargo weights entered by the user. It does not read a vehicle plate, inspect axle distribution or certify compliance.
What should a driver keep after a weighbridge check?
Keep the issued weighing certificate or receipt, any correction or reweighing evidence, the waybill and the dispatch record, subject to the authority's current process.
Is the cheapest load always the fullest truck?
No. A fuller load can still be unsafe, unlawful, poorly secured, operationally delayed or uneconomic after handling, route, time, fuel and return-load costs are included.
