Vehicle maintenance is a core duty linked to an operator licence. Operators need a clear system that keeps every vehicle and trailer safe, roadworthy and properly recorded.
When that system fails, the Driver and Vehicle Standards Agency, known as DVSA, may investigate. Serious or repeated concerns may be reported to the Traffic Commissioner. This can lead to a public inquiry, where the future of the operator licence is examined.
A public inquiry is a formal tribunal hearing. Possible outcomes include warnings, extra conditions, curtailment, suspension, revocation or disqualification.
Why Maintenance Problems Lead to Public Inquiries
Every operator gives undertakings when completing an operator licence application. These promises include keeping vehicles fit and serviceable, reporting defects, following inspection intervals and keeping proper records.
The same duties apply to standard national, standard international and restricted operators licence holders. A restricted licence holder may not need a qualified transport manager, but the operator still carries full responsibility for roadworthiness.
DVSA investigations review vehicle condition, inspection records, driver defect reporting, maintenance facilities, tyres, wheels, brakes and roadside prohibition history. Serious gaps may be reported to the Traffic Commissioner.
Missed or Late Safety Inspections
One of the clearest warning signs is a missed safety inspection.
Operators must follow the inspection frequency recorded on the Vehicle Operator Licensing service. Inspections should be planned and completed on time. A busy week, staff shortage or workshop delay does not remove this duty.
Common failures include:
- Booking inspections after the due date
- Failing to inspect trailers
- Changing intervals without updating the licence record
- Returning a vehicle before the inspection is complete
A single late inspection may have an explanation. A pattern suggests weak control. Use a forward planner, reminders and backup workshop capacity.
Weak Driver Walkaround Checks
Drivers must complete a walkaround check before using a vehicle for the first time each day. The check should cover tyres, lights, wheel fixings, bodywork, trailer coupling and load security.
Problems arise when checks become a tick-box task. Drivers may sign forms too quickly, copy old entries or ignore visible faults.
Warning signs include:
- No written instructions
- Little driver training
- Checks completed after departure
- Defects reported by text with no formal record
- Nil-defect reports that do not match vehicle condition
Give drivers enough time to inspect the vehicle. Train them to spot faults. Managers should compare defect reports with workshop findings and roadside results.
Missing or Incomplete Maintenance Records
Good maintenance without good records is hard to prove.
Safety inspection and repair records must normally be kept for at least 15 months. Records should identify the vehicle, date, inspector, items checked, defects found, repairs completed and the final roadworthy declaration. Driver defect reports and repair details also form part of the maintenance history.
Common failures include missing sheets, blank sections, no repair details, unclear vehicle identity and no signed declaration. Electronic records also need an audit trail, secure storage and backups.
The transport manager or responsible person should review each inspection before the vehicle returns to service.
Defects Reported but Not Repaired
A sound defect system must lead to action.
Some operators record faults but continue using the vehicle. Others accept a casual comment that a defect is “fine for now”. This is dangerous when the fault affects brakes, tyres, steering, lights, coupling equipment or load security.
Every defect should be assessed by a competent person, repaired where needed and signed off before release. Staff must know who has authority to take an unsafe vehicle out of service.
Poor Brake Testing and Maintenance
Every safety inspection must include a proper assessment of braking performance. A simple road test is not enough on its own.
Official guidance lists methods such as:
- Laden roller brake testing
- A suitable decelerometer process for rigid vehicles
- Electronic braking performance monitoring
The testing method and result should be recorded.
Warning signs include:
- No brake performance evidence
- Repeated low readings
- Defects carried forward without action
- Trailer brakes receiving less attention
- No review of brake trends
Review the full report, not only the pass or fail result. Trends often reveal wear before a serious fault develops.
Poor Tyre and Wheel Management
Operators should manage tyre condition, tread depth, pressure, damage, age and replacement. Wheel removal and refitting also require clear procedures, including checks and retorque arrangements where needed.
A recent Traffic Commissioner decision involved late inspections, missing defect records, poor tyre and wheel management and weak action on known faults. The operator’s licence was revoked, and the operator was disqualified.
Repeated small failures can show that the wider system is not working.
Over-Reliance on a Maintenance Contractor
Using an outside garage does not transfer legal responsibility.
The operator remains responsible for every vehicle and trailer. A written agreement should set out the work, inspection frequency, vehicle types and reporting process. Operators should review inspection quality and challenge incomplete records.
Check whether the provider:
- Has suitable equipment
- Completes inspections on time
- Includes proper brake testing
- Records all repairs clearly
- Sends records without delay
- Investigates repeat faults
Transport consulting support can help operators audit contractors before DVSA finds the gaps.
Repeated MOT Failures and Roadside Prohibitions
One MOT failure does not always lead to a public inquiry. Repeated failures involving safety items can show weak maintenance control.
Roadside prohibitions raise similar concerns. The Traffic Commissioner may ask whether the defect should have been found during the daily check, whether it appeared earlier and whether management ignored a pattern.
Review every failure and prohibition. Record the cause, corrective action, training and follow-up check.
Do not treat an MOT pass as a complete maintenance system. The annual test only confirms the vehicle’s condition at the time of the test. Operators must keep vehicles safe throughout the year.
A Practical Example
A small haulage firm misses a six-week inspection because the workshop is full. A driver reports a worn tyre, but the message stays on a manager’s phone. DVSA then finds the tyre defect and a brake issue.
The operator cannot produce a complete planner or signed repair records. The maintenance contract is out of date. Several driver reports appear rushed.
The public inquiry is no longer about one tyre. It is about whether the system works and whether the operator can be trusted.
This is why operators must look beyond individual defects. One fault can expose wider failures in planning, training, supervision and record keeping.
How to Reduce the Risk
Plan Every Inspection
- Set inspection dates well in advance
- Include every vehicle and trailer
- Add reminders and backup workshop dates
- Update changes through the licensing service
- Allow time for repairs before vehicles return to work
Strengthen Driver Checks
- Train drivers on walkaround checks
- Give them enough time to complete each check
- Review all defect reports
- Challenge repeated nil-defect reports
- Confirm that reported faults were repaired
Keep Complete Records
- Retain records for at least 15 months
- Store brake evidence with inspection sheets
- Record every repair and roadworthy declaration
- Back up electronic files
- Make records available when DVSA requests them
Review Performance
- Track MOT results and prohibitions
- Look for repeat defects
- Audit the garage or internal workshop
- Review brake and tyre trends
- Act before the same fault returns
What Happens at the Public Inquiry?
The call-up letter explains the concerns and evidence to be considered. For an existing goods vehicle operator licence, the notice period is normally at least 21 days. Prepare the requested records and evidence of corrective action.
Do not wait for the hearing to fix the system. Show what failed, why it failed and what has changed.
Useful evidence may include:
- Updated maintenance contracts
- Completed inspection planners
- Driver training records
- Internal audit results
- Brake test reports
- Revised defect procedures
- Proof that repeat problems have stopped
The Traffic Commissioner will focus on whether future compliance is reliable. Honest evidence, complete records and lasting improvements carry more weight than promises.
Do not assume that licence renewal, restoration, reinstatement or reactivation will follow once repairs are complete. The final decision rests with the Traffic Commissioner.
Maintenance Duties and Licence Applications
Maintenance planning starts before the licence is granted. A new operator licence application should include suitable inspection arrangements and a reliable provider where work is outsourced.
Businesses searching for operators Licence UK guidance should follow the rules for goods vehicles. A pco operator licence application concerns private-hire operations and is separate from a goods vehicle operators licence.
The true operators licence cost is not limited to application fees. Poor systems lead to repair bills, lost work, vehicle downtime, professional fees and regulatory risk.
Whether you hold a standard vehicle operators Licence or a restricted operators licence, safe vehicles and reliable records remain essential.
