The Traffic Commissioner’s “Seven Deadly Sins” – Are You at Risk in 2025?
Starting out in the road transport and logistics industry can be both exciting and overwhelming. From the moment an operator’s licence is granted, there is a legal duty to maintain full compliance with a wide range of regulations covering vehicles, drivers, operating centres, record-keeping, and more.
The Driver and Vehicle Standards Agency (DVSA) and the Office of the Traffic Commissioner (OTC) are responsible for monitoring and enforcing these obligations. The consequences for non-compliance can range from a warning letter to the suspension or revocation of your operator’s licence, and even personal disqualification of company directors or transport managers.
Among all possible infringements, there is a group known informally (but seriously) as the “Seven Deadly Sins”, a list of the most serious offences that frequently lead to disciplinary action before a Traffic Commissioner.
So, what are the Seven Deadly Sins in 2025, and why must every operator avoid them at all costs?
The Seven Deadly Sins of Operator Compliance:
- Exceeding drivers’ hours limits by 25% or more
This includes breaching daily, weekly, or fortnightly driving time rules as defined by EU Regulation 561/2006 or the GB domestic drivers’ hours rules. Fatigue remains one of the top risks on UK roads. - Failure to install, use, or download data from a tachograph
Or worse, falsifying tachograph records. The DVSA sees this as intentional deception, often prompting Public Inquiries. - Using a false digital tachograph card or another driver’s card
This is both a regulatory breach and a criminal offence, often resulting in prosecution and licence revocation. - Operating a vehicle with serious mechanical defects or no MOT
Ensuring vehicle roadworthiness is one of your core operator licence undertakings and is non-negotiable. - Carrying dangerous goods without proper documentation or identification
Mismanaging hazardous loads breaches ADR regulations and endangers lives. Operators must ensure vehicles and drivers are fully trained and certified. - Driving without a valid or relevant driving licence
Operators are expected to check and record licence details. Ignorance is no defence in law. - Significant vehicle overloading
Overloaded vehicles are unsafe and illegal. This breach is viewed as a risk to road safety and a threat to fair competition in the industry.
What Happens If You’re Suspected?
If a DVSA examiner believes one of these sins has been committed, the operator may be called in for a PACE interview under caution, followed by a Public Inquiry led by a Traffic Commissioner. This is a formal legal process where operators must explain how the breach occurred and what corrective actions have been taken.
You’ll be expected to provide evidence of improved systems, training, and oversight and to prove that the same mistake won’t happen again. The Traffic Commissioner’s decision will depend on your conduct, preparation, and attitude toward compliance.
