Next time you’re driving on the N3, take a look at the trucks around you. Some will be carrying supermarket stock, vehicle components or building materials. Others, despite looking exactly the same, won’t be carrying anything at all.
Their deliveries have already been completed, and they’re making the journey back with an empty trailer.
For the average motorist, it probably goes unnoticed. For the logistics industry, it’s one of the biggest challenges on South Africa’s roads.
Every kilometre still costs money. The truck still burns fuel, the tyres continue to wear, the driver is still on the clock and the vehicle is unavailable for another job. The only thing that’s missing is the load.
The Delivery Might Be Finished, But the Trip Isn’t
Dropping off the last pallet doesn’t mean the day’s work is over.
As soon as a truck is unloaded, the focus shifts to the next journey. Ideally, there’s another load waiting nearby. If there is, the vehicle keeps moving and continues earning revenue. If not, it heads back empty, ready for its next assignment.
That might not sound like a major issue, but think about it across hundreds of trucks travelling every day. What looks like the occasional empty trailer quickly becomes thousands of kilometres where expensive equipment is moving without transporting a single product.
Empty Space Comes at a Cost
It’s easy to assume empty kilometres are mainly about fuel, but the impact runs much deeper.
Every trip still adds wear to the truck. Drivers still spend hours on the road. Maintenance schedules don’t change simply because the trailer is empty. More importantly, every truck travelling without freight is capacity that could have been used somewhere else.
In an industry where margins are often tight, getting more from the fleet you already have is usually far more valuable than simply adding another vehicle.
There’s No Simple Fix
If reducing empty kilometres were easy, the problem would have disappeared years ago.
A return load isn’t always available where a delivery ends. Customer collection times may not line up. Warehouses have different operating hours. Production schedules change. Sometimes the next load is simply too far away to make commercial sense.
That’s why transport planners spend so much time looking beyond individual deliveries. They’re constantly trying to connect one journey to the next, finding opportunities to keep trucks loaded for as much of the day as possible.
Technology has made that easier, but it hasn’t replaced experience. Knowing where freight is moving, understanding customer operations and building strong relationships across the supply chain still play a huge role in making those decisions.
Every Journey Counts
Whether a truck returns with another load often has very little to do with the transport company alone. Production schedules, warehouse operations, customer delivery windows and even where businesses are located all influence what happens once a delivery has been completed.
Most people driving past a truck will never know whether it’s carrying a full load or an empty trailer, and chances are they’ll never think twice about it. Yet for the businesses behind the scenes, that difference shapes everything from operating costs to fleet capacity and customer service. In logistics, making the delivery is only part of the job. Finding a way to make the journey back count is where the real challenge begins.
