Operator licence undertakings - what you actually promised the Traffic Commissioner
Undertakings are the promises you sign when a licence is granted - on roadworthiness, drivers' hours, records, weights and operating centres. Breaching them is the most common route to a public inquiry, because the Commissioner need only show a promise was not kept.
When a licence is granted, the applicant signs a set of undertakings - promises to the Traffic Commissioner. They are printed on the licence and repeated on every continuation. Breaching them is the most common route to a public inquiry, because the Commissioner does not need to prove an offence, only that the promise was not kept.
The standard undertakings
- The laws relating to the driving and operation of vehicles used under this licence are observed. Drivers' hours, tachograph use, construction and use, speed limiters, weights, the lot.
- The rules on drivers' hours and tachographs are observed, proper records are kept and that these are made available on request. Driver cards downloaded at least every 28 days, vehicle units every 90, records kept 12 months, analysed and acted on.
- Vehicles and trailers, including hired vehicles and trailers, are not overloaded.
- Vehicles operate within speed limits.
- Vehicles and trailers, including hired vehicles and trailers, are kept fit and serviceable. This is the roadworthiness undertaking: daily walkaround checks, safety inspections at the stated frequency, defect rectification, annual test.
- Drivers report promptly any defects or symptoms of defects that could prevent the safe operation of vehicles and/or trailers, and that any defects are promptly recorded in writing.
- Records are kept (for 15 months) of all driver defect reports, all safety inspections, routine maintenance and repairs to vehicles, and that these are made available on request.
- In respect of each operating centre specified, that the number of vehicles and trailers kept there will not exceed the maximum numbers authorised.
- An unspecified vehicle is not used for more than one month (28 days) without being specified on the licence, and the Traffic Commissioner is told about changes of maintenance arrangements, convictions, and anything else material.
Standard licences add the requirements for professional competence (a transport manager with CPC) and financial standing.
What "continuous and effective management" looks like in practice
The Senior Traffic Commissioner's statutory guidance expects the transport manager to show systems, not good intentions:
- A maintenance planner six months ahead, by ISO week, with inspections actually done in the planned week (see safety inspection intervals).
- Driver defect reports every day, including nil reports, with rectification recorded.
- Annual test first-time pass rate monitored; failures investigated.
- Tachograph analysis with infringements debriefed and signed, repeat offenders escalated.
- Licence checks on a documented cycle with driver consent on file.
- Training records, including Driver CPC and walkaround training.
- Evidence that the TM reviews all of it - sign-offs, notes, actions.
Evidence the examiner will ask for
At a DVSA maintenance investigation or traffic examiner visit, expect to produce: the planner; 15 months of inspection sheets with brake-test results; defect books or app records; annual test history; tachograph download records and analysis; driver licence check records; the maintenance contract (Annex 5 of the DVSA guide) if inspections are contracted out; VOR records.
OperatorCompliance keeps the dated items (tests, inspections, downloads, licence checks, CPC, cards) in one calendar, stores the signed tachograph reports and licence evidence against each driver, and produces a monthly compliance pack you can file.
When something goes wrong
Tell the Traffic Commissioner before they find out: a change of maintenance provider, a prohibition with an "S" marking, a conviction, a fixed penalty for drivers' hours. The Commissioners consistently treat candour and a credible recovery plan as strong mitigation.
Frequently asked questions
What are the undertakings on an operator's licence?
They are the promises you sign when the licence is granted, printed on the licence and repeated at continuation. In outline they cover observing the law on driving and vehicles, keeping drivers' hours and tachograph records, not overloading, keeping to speed limits, keeping vehicles fit and serviceable, prompt defect reporting, keeping records for 15 months, and not exceeding operating centre capacity.
What happens if I break an undertaking?
Breaching an undertaking is the most common route to a public inquiry, because the Traffic Commissioner does not need to prove a separate offence, only that the promise was not kept. Depending on severity the Commissioner can warn, curtail, suspend or revoke the licence, and can act against a director's or transport manager's good repute.
What does continuous and effective management look like in practice?
The Senior Traffic Commissioner's guidance expects the transport manager to show systems, not good intentions: a maintenance planner running months ahead by ISO week, daily driver defect reports including nil reports, annual test pass rates monitored, tachograph infringements debriefed and signed, licence checks on a documented cycle, training records, and evidence the manager reviews it all.
What must I tell the Traffic Commissioner about, and when?
Tell them before they find out. A change of maintenance provider, an S-marked prohibition, a relevant conviction, a fixed penalty for drivers' hours, or a change of transport manager or company structure are all things to report. Commissioners consistently treat candour and a credible recovery plan as strong mitigation, so early honesty protects your repute.
