Forgive the rookie question. I regularly drive an 18t box truck. What does 18t mean? Is that its weight empty? Or its maximum weight? If that then what is it likely to weigh empty?
Somebody loaded me this week and said I might be overweight there but they didn’t have a weigh bridge and I’m not sure what ‘overweight’ would have been anyway.
If you take a look under your passenger seat you will have a plate that tells you what your maximum weights are. However an 18t vehicles maximum permissable weight is 18t, that’s unladen weight plus payload.
For the purpose off weight restrictions you cannot go anywhere that is showing lower than 18t as the signage is aimed at your maximum permissable weight, even if you are running empty and weighing in at 9t.
If you think the lorry is overloaded then, providing it is not unsafe, you can legally drive to the nearest public weighbridge and then back to the place of loading to remove goods if overloaded
You get the money for the weighbridge back from your boss because they have to pay not the driver
Your boss can then get the money back from the company that overloaded you
18 tonne in your case is the vehicle GVW or max Gross Vehicle Weight which is the most it can legally weigh with you, the load, fuel, sandwiches, wet wipes etc
