What undertakings are
When a Traffic Commissioner decides whether to grant a goods vehicle operator licence, section 13C of the Goods Vehicles (Licensing of Operators) Act 1995 requires them to be satisfied about three sets of arrangements: for complying with the drivers' hours rules, for making sure vehicles are not overloaded, and for maintaining vehicles "in a fit and serviceable condition". A heavy goods vehicle licence must also specify at least one suitable operating centre.
Section 13C(7) lets the Commissioner take into account any undertakings the applicant gives, and assume they will be fulfilled. That is the bargain at the heart of operator licensing: the licence is granted because of the promises made, and the operator is expected to keep them for as long as it holds the licence. The Guide to Maintaining Roadworthiness notes that these undertakings were "formerly known as 'statements of intent'". The licence document itself lists any conditions and any undertakings relevant to its grant.
The general undertakings
The application for a new licence, form GV79, is now normally made online through the vehicle operator licensing service (VOL). The standard undertakings are recited in published Traffic Commissioner decisions. A decision published on GOV.UK in July 2026 describes them as "formal and binding promises" and lists them as follows:
- the laws relating to the driving and operation of vehicles used under the licence are observed;
- the rules on drivers' hours and tachographs are observed, proper records are kept, and these are made available on request;
- vehicles and trailers are not overloaded;
- vehicles operate within the speed limits;
- vehicles and trailers, including hired vehicles and trailers, are kept in a fit and serviceable condition;
- drivers report promptly any defects or symptoms of defects that could prevent the safe operation of vehicles or trailers, and defects are recorded in writing;
- records are kept for at least 15 months of all driver defect reports and all safety inspection, routine maintenance and repair reports, and are made available on request;
- the number of vehicles and trailers kept at each operating centre does not exceed the number authorised;
- an unauthorised operating centre is not used in any traffic area;
- the licensing authority is told of any relevant convictions or accepted fixed penalties against the licence holder, its employees or agents;
- the licensing authority is told within 28 days of any other changes that might affect the licence, such as changes to maintenance arrangements, financial status or legal status.
Check the exact wording recorded on your own licence. Older licences, and licences granted after a hearing, may carry different or additional undertakings.
Maintenance arrangements and inspection frequency
Alongside the undertakings, the application records your maintenance arrangements: who carries out safety inspections and how often. The Guide to Maintaining Roadworthiness says any change to those arrangements "must be updated" on VOL. Traffic Commissioners have treated missed inspection intervals as an unfulfilled "statement of expectation", which is a separate ground for action under section 26(1)(e).
Conditions a Traffic Commissioner can attach
Conditions are imposed by the Commissioner under specific statutory powers, rather than offered by the operator. The main types are:
| Power | What the condition can cover |
|---|---|
| Section 21 (heavy goods vehicle licences) | Road safety where vehicles join or leave a public road on the way to or from an operating centre |
| Section 22(1) | Requiring the holder to report specified changes in the organisation, management or ownership of the business, or other specified events |
| Section 22(2) (standard licences, mandatory) | Reporting, within 28 days, any event that could affect the licence holder's or transport manager's ability to meet the licence requirements |
| Section 23 (heavy goods vehicle licences) | Environmental conditions on an operating centre, such as the number, type and size of vehicles, parking arrangements and operating hours |
Before attaching or tightening a section 21 or 23 condition, the Commissioner must give the operator an opportunity to make representations about the effect on its business. Under section 26(2), where there are grounds for regulatory action, the Commissioner can also attach a new section 22(1) condition.
Undertakings and conditions compared
Both are recorded on the licence and both bind the operator. The practical differences are these:
- Origin. An undertaking is a promise given by the operator. A condition is imposed by the Commissioner.
- Scope. Statutory Document 10 notes that, following Upper Tribunal case law, there is an implicit power to accept undertakings on matters beyond section 13C, such as training. Conditions are limited to what the Act allows.
- Consequences. Contravening a section 21, 22 or 23 condition is a criminal offence as well as a ground for action against the licence under section 26(1)(b). An unfulfilled undertaking is a ground for action under section 26(1)(f).
Statutory Document 10 adds that once an undertaking is given, there can be no valid appeal on the basis that it should not have been required at all.
What happens if you breach them
If a ground under section 26 is brought to the Commissioner's notice, the Act requires them to consider whether to revoke, suspend or curtail the licence. The GOV.UK operator licensing guide lists breaking a condition or not keeping an undertaking among the reasons a Commissioner may act.
Statutory Document 10 makes clear that an undertaking is about active management, not paperwork. Summarising appeal case law, it says a statutory undertaking requires the operator to set up adequate systems and "not allow them to run themselves", with "constant supervision and monitoring". It also notes that in cases of persistent breaches "it will be difficult for an operator to contend that it has complied with its undertaking".
Outcomes range from no action or a warning to further undertakings, curtailment, suspension, revocation and disqualification. Where a Commissioner accepts new undertakings to resolve a case, Statutory Document 10 gives examples such as an audit carried out in 6, 9 or 12 months with the report sent within a month, a transport manager refresher course, or laden roller brake tests four times a year. It also warns that a Commissioner is under no obligation to accept further undertakings from an operator that has ignored previous advice.
How to show you are meeting each one
A promise is only as good as the evidence behind it. The table below links each general undertaking to the records a DVSA examiner, auditor or Traffic Commissioner is likely to ask for.
| Undertaking | Day-to-day evidence |
|---|---|
| Vehicles and trailers kept fit and serviceable | A forward planner showing inspections at the declared frequency; completed safety inspection sheets with a signed roadworthiness declaration; brake performance assessed at every inspection; MOT and prohibition history reviewed |
| Drivers report defects in writing | Walkaround check records, at least one in every 24-hour period the vehicle is used; defect reports showing who received each one, how it was assessed and when it was repaired |
| Records kept for 15 months | Complete maintenance files, including for vehicles removed from the licence, retrievable on request |
| Drivers' hours and tachograph rules observed | Regular vehicle unit and driver card downloads, infringement reports, and records of how each infringement was followed up with the driver |
| No overloading | Loading procedures, driver training and weight checks appropriate to the work |
| Operating centre and authorisation | Vehicles kept only at authorised centres, within the numbers authorised and in line with any environmental conditions |
| Notifications within 28 days | A log of changes and convictions and the date each was reported on VOL |
The Guide to Maintaining Roadworthiness recommends inspection intervals between 4 and 13 weeks depending on the work, and a minimum of 6 weeks for vehicles and trailers aged 12 years or older. Where electronic braking performance monitoring is not used, it expects a minimum of four laden brake tests spread evenly across the year, which can include the annual test.
Outsourced maintenance
Using a garage does not transfer the undertaking. The Guide states that even with a maintenance contract, the operator "remains legally responsible" for the condition of the vehicle, the authorisation of repairs and the retention of records. The transport manager should review returned inspection sheets rather than simply file them.
Keeping your undertakings under review
- Read the undertakings and conditions printed on your licence, not a generic list.
- Check the maintenance provider and inspection frequency on VOL match what actually happens.
- Diary any time-limited undertaking, such as an audit or training deadline, with the date evidence is due.
- Test your systems regularly, for example with an independent audit, and keep the evidence of what you changed.
Roadworthy supports several of these records: QR-card walkaround checks without an app or login, defect tracking from report to sign-off, an inspection and brake-test calendar with advance notice, and a transport manager's signed weekly record against Statutory Document No. 3.
