Police, DVSA examiners and trading standards officers can require a vehicle to be checkweighed.
Weighing may be by conventional weighbridge, dynamic weighing device (WIMS) or electronic weigh pads recording axle readings.
Drivers must cooperate, including driving to a nominated weighbridge if required.
A certificate confirming the weighing result is provided whether or not the vehicle is overloaded.
If overloaded on gross weight or an individual axle, a TE 160 prohibition notice may be issued.
TE 160 can prohibit movement until excess weight is removed or allow controlled movement to a specified place where the excess can be removed safely.
Once the excess weight is removed, the prohibition can be removed.
A vehicle found within limits is exempt from another weight check on the same journey with the same load.
For international container and swap-body movements, the cargo owner must provide the haulage operator with the weight of the goods; the source also refers to proof that the load and transport unit will not cause overloading.
Responsibility for overloading lies with both driver and operator.
The source states a maximum fine of £5,000 for using or permitting the use of an overloaded vehicle.
An overloading offence is reported to the relevant Traffic Area Office and recorded against the operator's O licence and driver's LGV entitlement.
The Traffic Commissioner may take disciplinary action against the operator, driver or both following conviction.
Graduated fixed penalties for overloading can range from £100 to £300 according to severity, as stated in the training material.
Enforcement officers may immobilise vehicles until excess weight is removed.
The driver pays the fixed penalty; the operator is notified and, under the O-licence terms stated in the material, must report it to the Traffic Commissioner.
