93% of Operators Face Penalties at Traffic Commissioner Inquiry

If you hold an operator's licence, a call to a Traffic Commissioner public inquiry is the single most stressful letter you can receive. For most operators it's also avoidable, provided you know what the Commissioners are actually looking for before they come looking for you.

What the numbers show

In 2023–24, the UK's Traffic Commissioners held 1,283 public inquiries. Of those, only around 7% resulted in no action at all. That means the overwhelming majority of operators called to inquiry left with some form of regulatory consequence: a formal warning, a curtailment of their licence, suspension, or in the more serious cases, full revocation and disqualification of the transport manager.

That statistic tends to surprise people. Many operators assume a public inquiry is something that happens to genuinely bad actors: companies ignoring the rules outright, cutting corners on maintenance, falsifying records. In reality, a large share of inquiries are triggered by operators who thought they were compliant, and who are caught out by gaps they didn't know existed until the DVSA or a Traffic Commissioner's office pointed them out.

The most common triggers

Across the inquiries held each year, three categories account for the bulk of the findings against operators:

Maintenance failures. These aren't necessarily catastrophic mechanical faults. More often it's inconsistent inspection intervals, missing driver defect reports, or a maintenance contract that looks fine on paper but isn't being followed in practice. DVSA roadside checks and annual test failure rates are two of the clearest early warning signs an operator has drifted out of compliance without realising it.

Drivers' hours and working time violations. Digital tachograph data makes these violations far easier to detect than they once were, but many operators still aren't actively monitoring the data they're already collecting. A tachograph analysis system that flags infringements after the fact isn't the same as a system that prevents them.

Loss of financial standing. This one catches people off guard because it isn't about driving behaviour or vehicle condition at all. It's a requirement that operators demonstrate they have the financial resources to run a compliant operation. Cash flow problems, however temporary, can trigger a review of financial standing that then exposes other compliance gaps.

Why "we've always done it this way" isn't a defence

One pattern that comes up repeatedly at inquiry is an operator's genuine belief that their existing processes were adequate, simply because they'd never been challenged before. Compliance isn't static. Regulations get updated, DVSA's enforcement priorities shift year to year, and a system that was sufficient five years ago may quietly have fallen behind current expectations without anyone at the company noticing.

This is exactly the gap that continuing professional development, and periodic independent review, are designed to close. A transport manager who last had their systems checked when the operator's licence was first granted is working from an increasingly outdated picture of what "compliant" actually looks like.

What a defensible position looks like

Operators who come through DVSA scrutiny well, whether that's a routine desk-based assessment or a full public inquiry, tend to share a few things in common:

• Evidence, not assertions. It's not enough to say drivers are briefed on their hours; there needs to be a record showing when, how, and what was covered.
• A defect reporting process that's actually used by drivers day to day, not one that exists only in a policy document.
• Regular, honest internal review, ideally from someone independent of daily operations who isn't invested in believing everything is fine.
• A transport manager who can demonstrate genuine and continuing engagement with the operation, not just a name on the licence.

The takeaway

The 93% figure isn't meant to be alarming for its own sake. It's a reminder that "we haven't had a problem yet" and "we're compliant" are not the same statement. Most operators who end up at inquiry didn't think they'd get there either.

A periodic, independent compliance health check exists precisely to surface the kind of gap that's invisible from the inside, before a DVSA request or Traffic Commissioner letter finds it for you.
