It is a common misconception that if a vehicle is found to be overweight, then both the owner/operator and the driver will automatically be guilty of an offence.
In fact, if the driver is a sub-contractor, then the owner/ operator should not be charged with the strict liability offence of “using” the vehicle, which confines the prosecution to alternatives of “causing” or “permitting” the offence.
Understanding the distinction between these terms is critical for operators in order to understand whether they have a defence available.
What Does “Permitting” Mean?
In transport prosecutions, “permitting” generally requires proof that the operator had either:
- actual knowledge of the offending conduct; or
- constructive knowledge arising from inadequate systems, supervision, or management.
Actual knowledge is relatively straightforward.
Constructive knowledge is more nuanced and may arise where:
- There are no meaningful compliance systems in place.
- Drivers receive little or no training;
- Management fail to supervise loading practices;
- Known risks are ignored; or
- The business effectively “turns a blind eye” to non-compliance.
The court will look closely at whether the operator took reasonable steps to prevent overloading.
Financial And Regulatory Consequences
Businesses sometimes underestimate the seriousness of overweight prosecutions.
In addition to court fines, overweight offences can trigger:
- DVSA investigations;
- Public Inquiry proceedings.
Where a company has a significant turnover, fines for corporate defendants can be substantial (as the fine is unlimited).
Practical Steps Operators Should Take
Operators using employees, agency drivers, or subcontractors should regularly review their compliance systems.
Practical steps include:
- Ensuring all drivers receive documented training on loading limits and weight distribution.
- Providing written policies and driver handbooks dealing specifically with overloading.
- Carrying out regular toolbox talks and refresher training.
- Implementing systems for drivers to raise concerns regarding unsafe or excessive loads.
- Auditing loading practices and retaining records.
- Reviewing subcontractor arrangements to ensure compliance responsibilities are clearly defined.
- Taking immediate action where breaches or concerns are identified.
Early Legal Advice Is Important
Many operators only seek legal advice after a guilty plea has already been entered or after enforcement action has escalated.
However, allegations involving “causing” or “permitting” overweight offences will usually benefit from a detailed consideration of the evidence as the bald fact that a vehicle was overweight is often not sufficient to establish liability for an offence.
Obtaining early specialist advice can make a significant difference to both the court outcome and the protection of your operator licence.
