O-licence undertakings: the dates you promised to keep
Updated 20 August 2026
When you signed your goods vehicle operator licence (O-licence) application, you signed a set of undertakings — binding promises to the Traffic Commissioner. Almost all of them boil down to dates: safety inspections at the intervals you stated, an annual test per vehicle, tachograph calibration, drivers' hours compliance, and records kept for at least 15 months. Miss the dates and you are not just late — you are in breach of the licence itself.
What you actually promised
The standard undertakings include:
- Vehicles and trailers are kept fit and serviceable, with safety inspections at the intervals stated on your licence (many operators state 6- or 8-weekly — whatever you declared is what you're held to).
- Drivers report defects in writing and defects are repaired promptly.
- Records of inspections, defect reports and repairs are kept for 15 months and produced on request.
- The rules on drivers' hours and tachographs are observed.
- You notify the Traffic Commissioner of relevant changes — maintenance arrangements, operating centre, convictions.
The dated items to track
Treat the undertakings as a compliance calendar. Per vehicle: the safety inspection (your stated interval), the annual test (MOT) every 12 months, and the tachograph calibration — see the tachograph calibration and download intervals for the two-year cycle and the 28/90-day downloads. Per driver: the Driver CPC (35 hours of periodic training every 5 years), regular licence checks, and tacho card expiry. Per company: insurance, the licence's own continuation date, and your transport manager's CPC standing.
OCRS: how DVSA keeps score
DVSA rates every operator with an Operator Compliance Risk Score (OCRS), built from roadside encounters, annual test results and prohibitions. Green means you're largely left alone; red means your vehicles get stopped more often, and a pattern of prohibitions or failed tests can trigger a DVSA investigation and a referral to the Traffic Commissioner. A missed inspection that leads to a roadside prohibition therefore costs you twice: the immediate downtime, and a score that invites the next stop.
What the Traffic Commissioner can do
Undertaking breaches end up at a public inquiry, where the Traffic Commissioner's powers escalate: curtailment (fewer authorised vehicles — a direct cut to revenue), suspension, or revocation of the licence, which stops the business overnight. Transport managers can lose their good repute. Commissioners consistently say the same thing in written decisions: it is rarely one bad day that sinks an operator, but records that show the promised intervals were quietly slipping.
The positive path: Earned Recognition
DVSA Earned Recognition is the other direction: operators who can prove consistently strong systems — via approved software that reports key performance indicators to DVSA — get fewer roadside stops and fleet inspections. The entry requirement is essentially the same discipline: inspections on time, records complete, dates never missed.
Keeping the promises visible
An O-licence is a system of recurring dates, and the 15-month record trail means every slip stays visible long after it happened. A wall planner or spreadsheet works only as long as someone checks it every week. Automatic reminders remove that single point of failure: Certly holds each vehicle's and driver's dates and emails you 90, 60 and 30 days ahead — early enough to book the workshop, not just to notice the breach.

Frequently asked questions
What are O-licence undertakings?
They are the legally binding promises you made when applying for your goods vehicle operator licence: keeping vehicles fit and serviceable, carrying out safety inspections at the intervals you stated, obeying drivers' hours and tachograph rules, keeping maintenance records for 15 months, and notifying the Traffic Commissioner of relevant changes. Breaching them puts the licence itself at risk.
How long must maintenance records be kept for an O-licence?
At least 15 months. That covers safety inspection reports, driver defect reports (including nil-defect reporting where used) and repair records. At a DVSA visit or public inquiry, gaps in this 15-month trail are treated as evidence the system isn't working.
What is OCRS?
The Operator Compliance Risk Score is DVSA's rating of how likely your vehicles are to be non-compliant, based on roadside encounters, annual test results and prohibitions. It runs from green through amber to red; a red score means more roadside stops and can lead to a referral to the Traffic Commissioner.
What can the Traffic Commissioner do if undertakings are breached?
At a public inquiry the Traffic Commissioner can curtail the licence (reduce the number of authorised vehicles), suspend it for a period, or revoke it entirely. Transport managers can lose their repute, which disqualifies them from the role. These powers apply to breaches of undertakings, not just to accidents.
