A public inquiry (PI) is the most serious regulatory action in the goods vehicle operator licensing system. It is a formal hearing before a Traffic Commissioner to decide whether you are fit to hold an operator licence. The stakes are high: outcomes range from compliance undertakings through to full licence revocation and personal disqualification.
If you have been called to a public inquiry, this guide explains what to expect, how to prepare, and what you can do to give yourself the best chance of a favourable outcome. Even if you have not yet been called, understanding the process helps you recognise warning signs early and take corrective action before matters escalate.
You need this guide if:
Public inquiries are quasi-judicial proceedings. Traffic Commissioners expect a professional standard of evidence and argument. A solicitor experienced in operator licensing knows what Traffic Commissioners look for and can present your case in the most effective way. General solicitors without transport licensing experience may not understand the specific regulatory framework.
The typical cost of legal representation ranges from around 2,000 to over 10,000 pounds depending on the complexity of your case, but losing your licence will cost far more in lost revenue, redundancies, and reputational damage.
DVSA must disclose its evidence before the hearing. Review every document with your solicitor. Identify any factual errors, missing context, or mitigating circumstances. The evidence typically includes:
Collect and organise the following:
Traffic Commissioners distinguish between operators who have addressed root causes and those who have merely fixed individual problems. Show that you have:
Both the licence holder (or a director authorised to bind the company) and the nominated Transport Manager must attend. Non-attendance without an exceptional reason is treated very seriously and can result in immediate revocation. If you are a sole trader, you must attend personally.
The Traffic Commissioner has a range of options. The Senior Traffic Commissioner's statutory guidance provides a framework, but each case is decided on its own facts. Outcomes typically escalate with the severity and frequency of non-compliance:
The Traffic Commissioner usually gives a decision at the end of the hearing, though complex cases may receive a written decision later. If the outcome includes undertakings or conditions, ensure you understand exactly what is required and by when.
If you believe the Traffic Commissioner made an error of law or reached a decision that no reasonable Commissioner could have reached, you can appeal to the Upper Tribunal (Administrative Appeals Chamber) within one month of the decision. Appeals are on points of law, not a rehearing of facts. Your solicitor can advise whether you have grounds.
