WHAT HAPPENS IF YOU'RE OVERLOADED

Overloading a truck is an absolute offence. In other words, the offfence is committed even where the driver or operator had no knowledge that the vehicle was overloaded. Unfortunately, even the most conscientious operator and driver can get it wrong. Moreover, consignors can (and often do) incorrectly state the weight of a load. Wherever possible get the consignor to confirm the cargo weight IN WRITING and make sure that the weight is on the weighbill/consignment note. It could be used in mitigation if you're then found to be overloaded.

ENFORCEMENT WEIGHING

AVOID DYNAMIC AXLE PITFALLS

The DOT operates a number of dynamic axle weighers in the UK for enforcement purposes. They have not been without their problems in operation. Any driver weighed on a dynamic axle weigher as part of a weigh check should apply the following "rules".

  1. Ensure your vehicle travels in a straight line for at least twice its length when proceeding on to the concrete apron BEFORE weighing to eliminate lateral forces which would affect the suspension.
  2. Stop the vehicle as directed six metres from the weighbeam with the footbrake and keep it applied WITHOUT applying the park brake.
  3. If you do apply the park brake, wait AT LEAST 10 seconds before setting off over the weighbeam after it is released, to ensure the spring brakes have sufficient time to release fully.
  4. Do NOT surge the vehicle with the accelerator, even by a slight amount as you pass over the weigh beam. If you do, abort the weighing by stopping the vehicle.
  5. Do NOT brake to check the speed of the vehicle. If you do, abort the weighing by stopping completely.
  6. Remember, you are NOT under any legal obligation to have only one weighing. So if either points 4 or 5 occur, stop the vehicle mid-weigh and apologise to the enforcement officer who will arrange further attempts.
  7. If you DO register a prosecutable overload which you genuinely consider incorrect, ask for a re-weigh and/or
  8. Proceed without delay to the nearest certificated plate weighbridge and obtain a weighbridge ticket in evidence, ensuring your tachograph records show that you have not stopped for a sufficiently long period to have discharged your load.
  9. Obtain any written information from the consignors and so on to verify the weight of the payload.
  10. Weigh the vehicle (and trailer) immediately in the unladen condition. These last three points will be invaluable in convincing a court should your vehicle have been inaccurately weighed.

CODES OF PRACTICE

THE RIGHT WEIGH

The use of either plate or dynamic axle weighbridges for enforcement purposes, as well as portable weighpads is stricly controlled under codes of practice published by the Department of Transport. These state the conditions under which check weighing can take place. For example, with all types the weighing MUST be carried out, or supervised by, an Authorised Officer fully conversant with the operation of the weighing equipment.

On dynamic axle weighers there is also a set proceedure to establish their initial acceptability and continuing accuracy, together with strict rules governing the construction of the dynamic axle test site including the level of the approach and exit to the concrete apron: eg for eight metres either side of the weighbeam the levels should be within a tolerance of +/- 3mm.

Not all weighings take place in accordance with the code of practice! And this could prove to be a vital defence should you be prosecuted for overloading. Copies of the lastest consolidated code of practice for enforement weighing can be obtained from the Vehicle Inspectorate office.
