How Higher Height Loads Can consume higher fuel When trucks carry cargo with higher height without wind deflector, it uses a lot more fuel.

This extra wind resistance makes the truck's engine work much harder to keep moving, which burns a lot more fuel. Truck companies have to pay more for fuel, and they often pass that cost onto their customers. So, if you buy something that's shipped on a high truck, you might end up paying more for it. Burning more fuel means more pollution goes into the air. This is bad for the environment. In simple terms: High height loads on trucks without wind deflectors consume lot of fuel, which costs more money and effect the environment.
