UK LGV driver accident claims (licence and Group 2 medical perspective)

UK LGV driver accident claims - FAQs

What is the difference between LGV and HGV in UK 2026 terminology?

+

LGV stands for Large Goods Vehicle and is the official DVLA / DVSA terminology used on the driving licence and in test administration. The term replaced HGV (Heavy Goods Vehicle) for licence-administration purposes in the 1990s when the UK aligned with the European licence categories under Directive 91/439/EEC, although industry speech in 2026 still routinely uses HGV. In current usage the two terms are interchangeable in conversation, but anything to do with the licence itself - the DVSA Module 1-4 LGV test, the DVLA-issued photocard showing Cat C or Cat C+E entitlement, the DVLA Form D4 medical for Group 2 vocational drivers - uses LGV. CityGrip uses LGV when the claim file is concerned with the licence pathway, the D4 medical, the Group 2 vision-standard or any DVLA fitness-to-drive review, and uses HGV when the file is concerned with the vehicle, the tachograph, the Driver CPC or the operator's O-licence. The two perspectives sit together on the same driver.

What is the DVSA route to a Cat C / Cat C+E LGV licence?

+

The DVSA LGV licence pathway runs through five formal stages. First, the applicant must hold a full Cat B (car) licence and apply to DVLA for the Cat C provisional entitlement using DVLA Forms D2 and D4 (the D4 is the Group 2 medical, signed off by a doctor, optician and medical examiner). Second, the LGV Theory Test in two parts - a 100-question Multiple Choice paper and the Hazard Perception clip test. Third, the Driver CPC Case Studies (Part 2) test sat at a DVSA theory test centre. Fourth, the Practical Test in two sessions - Module 3a Off-Road Exercises (reversing, coupling for C+E) and Module 3b On-Road Driving, each lasting approximately 30 and 60 minutes respectively. Fifth, the Driver CPC Practical Demonstration (Module 4) - a 30-minute load-security and vehicle-walk-round demonstration with a JAUPT-approved examiner. On a successful run the candidate holds the Cat C entitlement on the photocard and a Driver Qualification Card (DQC). Cat C+E is added by a separate practical test on an articulated combination.

How often does a UK LGV driver have to renew the D4 Group 2 medical?

+

The first DVLA Form D4 medical is required at the point of first application for the Cat C or Cat C+E provisional entitlement. After that the revalidation cycle is set by regulation 74 of the Motor Vehicles (Driving Licences) Regulations 1999 (SI 1999/2864). From licence issue to age 45 no scheduled revalidation is required, but the driver remains under a continuing duty to notify DVLA of any notifiable medical condition. From age 45 to age 65 the D4 is renewed every 5 years. From age 65 onwards the D4 is renewed every 12 months. The cost of the D4 sits with the driver and is typically around £85-£120 depending on the practitioner - the medical can be performed by the driver's own GP, by a DVLA-listed Group 2 medical practitioner or at one of the high-street occupational-health clinics that specialise in vocational medicals. A lapsed D4 is a stand-alone bar to the use of the Cat C / Cat C+E entitlement and engages section 87 of the Road Traffic Act 1988.

What is the Group 2 vision standard and how does it differ from a normal car-licence vision check?

+

Group 2 vision is materially stricter than Group 1 (car) vision. The Group 2 standard under regulation 73 of the Motor Vehicles (Driving Licences) Regulations 1999 (SI 1999/2864) requires Snellen visual acuity of at least 6/7.5 (corrected if necessary) in each eye separately, and at least 6/60 (corrected) in the worse eye. The horizontal visual field must be at least 160° with no significant defect within the central 70°, and the vertical field at least 30° (15° above and 15° below the horizontal meridian). Diplopia (double vision) is disqualifying unless fully corrected by a prism worn at all times when driving. Monocular vision is generally disqualifying for Group 2, although individual exceptions can be made on application. By contrast the Group 1 standard is the 20-metre number-plate test plus a visual acuity of 6/12 in each eye corrected. The D4 medical includes a sign-off by an optician or optometrist confirming the Group 2 standard is met, and DVLA may require a formal field test where there is any doubt.

What medical conditions must I notify DVLA of as a UK LGV driver?

+

Notifiable medical conditions for Group 2 vocational drivers are set out in regulation 73 of the Motor Vehicles (Driving Licences) Regulations 1999 (SI 1999/2864) and the DVLA medical staff guide 'Assessing fitness to drive'. The list runs to several dozen conditions and includes - most commonly - any myocardial infarction (MI), cardiac arrhythmia, implanted cardioverter-defibrillator (ICD) or coronary bypass; any insulin-treated diabetes (Group 2 rules are materially stricter than Group 1 and historically barred Type 1 / IDDM holders, with the current position requiring evidence of awareness of hypoglycaemia, no severe hypoglycaemic episode in the preceding 12 months and continuing self-monitoring); any epilepsy, blackout or unexplained loss of consciousness; obstructive sleep apnoea (OSA) with excessive daytime sleepiness, which is one of the most common single causes of Group 2 licence revocation in 2026; any significant visual-field defect; and any neurological condition (stroke, TIA, multiple sclerosis, Parkinson's disease, cognitive impairment). The driver's continuing duty to notify under section 92 of the Road Traffic Act 1988 is independent of the 5-yearly / annual D4 revalidation cycle.

What is the difference between Form D4 and Form D46P?

+

Form D4 is the DVLA Group 2 vocational driver medical examination report - the form used to apply for, or revalidate, a Cat C, Cat C+E, Cat D or Cat D+E entitlement. It is signed off by a doctor (physical-examination section), an optician or optometrist (vision section) and a medical examiner (overall fitness-to-drive opinion). Form D46P is the entirely separate over-70 self-declaration form sent by DVLA to every Group 1 (car) licence holder approaching their 70th birthday and every 3 years thereafter. The two forms are routinely confused but address different cohorts and different licence groups. A 70-year-old LGV driver renewing the D4 annually (the post-65 annual cycle for Group 2) does not use D46P; a 70-year-old car driver renewing the Cat B entitlement does not use D4. CityGrip records which form applies to the file at intake and confirms the date of the last submission.

Is obstructive sleep apnoea (OSA) really a common cause of LGV licence revocation?

+

Yes - and the position has tightened materially since 2020. Obstructive sleep apnoea with excessive daytime sleepiness is a notifiable condition under regulation 73 of the Motor Vehicles (Driving Licences) Regulations 1999 and is one of the single most common drivers of Group 2 licence revocation in 2026. DVLA's position is that an LGV driver with an Epworth Sleepiness Scale score above 10, with reported episodes of falling asleep at the wheel or with a sleep-study Apnoea-Hypopnoea Index above 15, must stop driving and notify DVLA. The licence is restored once continuous positive airway pressure (CPAP) compliance is evidenced (typically a download from the CPAP machine showing average usage above 4 hours per night across a 30-day period, plus a clinician's letter). A fatigue-related collision file routinely opens a sleep-medicine referral on the driver alongside the civil claim - partly to establish causation, partly to evidence the regulatory side of the file.

What happens to my LGV licence if I have a serious collision?

+

A serious collision involving an LGV driver can trigger several parallel processes. The civil personal-injury and property-damage claim runs through the at-fault driver's commercial-vehicle insurer under sections 143 and 151 of the Road Traffic Act 1988. Where the collision raises any fitness-to-drive concern - concussion or head injury, suspected cardiac event at the wheel, blackout, suspected stroke, or any other notifiable condition under MV(DL)R 1999 reg 73 - the driver's clinician has a duty under General Medical Council Confidentiality 2017 (paragraphs 67-74) to advise the driver to notify DVLA, and to notify DVLA themselves if the driver continues to drive against medical advice. DVLA may impose a temporary suspension under section 93 RTA 1988 pending a medical review, request a medical report under section 94 and ultimately revoke or shorten the licence. The driver's appeal route is to the Magistrates' Court under section 94A RTA 1988 within six months of the DVLA decision.

Can I appeal a DVLA decision to revoke my LGV licence?

+

Yes. Section 94A of the Road Traffic Act 1988 sets the right of appeal to the Magistrates' Court in England and Wales (or the Sheriff Court in Scotland) within six months of the DVLA decision. The appeal route is open against a refusal to issue, a refusal to renew, a revocation, a shortening of the licence period, or the imposition of a restriction. The Magistrates' Court rehears the medical evidence and can make its own order. A successful appeal is most commonly run on the basis that the DVLA decision rested on out-of-date clinical evidence, that the clinical position has materially improved since the decision (typical examples: CPAP compliance for OSA, twelve months free of severe hypoglycaemia for insulin-treated diabetes, post-revascularisation cardiac stability) or that the DVLA medical adviser's interpretation of the notifiable-conditions criteria was wrong. CityGrip records the DVLA decision letter on the file at intake and routes the appeal to a regulatory-specialist solicitor on separate written consent where the file warrants it.

I'm an agency LGV driver paid through PAYE - how does my loss-of-earnings claim work?

+

An agency-paid LGV driver is normally employed by the recruitment agency under a contract of employment, with the agency operating PAYE deductions at source and supplying the driver to a third-party operator who provides the vehicle and load. The loss-of-earnings claim is built on net agency earnings for any period of incapacity caused by a non-fault collision. The evidence pack runs to 13 weeks of agency payslips covering the basic shift rate, any night-rate, weekend uplift and accommodation allowance; the most recent P60 (and P11D where applicable); a confirmation letter from the agency's payroll function stating the contracted shift pattern, the daily rate and the period the driver was unable to work; a fit-note (Med 3) or hospital discharge summary; and any Statutory Sick Pay record. The claim runs against the at-fault driver's commercial-vehicle insurer under section 151 RTA 1988 and CityGrip builds the loss-of-earnings pack at intake. The agency is not a defendant - the claim is against the at-fault driver's insurer.

I'm a self-employed LGV driver through my own limited company - how does IR35 affect my claim?

+

A self-employed LGV driver trading through a personal service company (PSC) - invoicing the agency or end-client and drawing a mix of salary and dividend - sits inside the Off-payroll Working Rules under Chapter 10 of Part 2 of ITEPA 2003, as inserted by Schedule 1 to Finance Act 2020 (commonly called IR35). The end-client or fee-paying agency must produce a Status Determination Statement (SDS) classifying the engagement as either inside or outside IR35. An inside-IR35 engagement is taxed at the worker level as if it were employment income and the loss-of-earnings analysis on a claim file looks more like an employee's - net deemed-employment pay over the period of incapacity, evidenced by invoices, dispatch records and the SDS. An outside-IR35 engagement is taxed on the PSC's trading profit, and the loss-of-earnings analysis is built on net trading profit attributable to the driver's working time, evidenced by 8-13 weeks of invoices and dispatch records, the company's bank statements, expense ledgers, the most recent statutory accounts and the driver's HMRC SA302. CityGrip records the SDS on the file at intake.

How does the limitation period work on an LGV-driver claim?

+

Three years from the date of the accident or the date of knowledge for any personal-injury claim under section 11 of the Limitation Act 1980. Six years from the date of the accident for property damage, loss of earnings and other consequential losses under section 2 of the same Act. Where the at-fault driver was uninsured or untraced the Motor Insurers' Bureau Uninsured Drivers' Agreement 2015 and Untraced Drivers' Agreement 2017 carry their own short notification windows that must also be met. Where a DVLA licence-revocation appeal is in play the section 94A RTA 1988 deadline is six months from the DVLA decision letter and runs independently of the civil-claim limitation period. Where the injured party is a child the personal-injury clock does not start until the 18th birthday; where the injured party is a protected party under the Mental Capacity Act 2005 the clock does not run while protection continues. CityGrip records every limitation date on the file at intake and diaries each one independently.

Will my fit-note (Med 3) by itself be enough evidence of incapacity?

+

On a low-severity soft-tissue file the Med 3 fit-note is usually sufficient. On any LGV-driver file with potential fitness-to-drive consequences the Med 3 is typically supplemented by an occupational-health assessment and, where appropriate, a clinician's letter dealing specifically with Group 2 fitness to drive. The reason is that an LGV driver who is medically fit to perform other work may still be unfit to drive a Cat C or Cat C+E vehicle under the Group 2 standard - concussion symptoms, post-traumatic stress, sleep disturbance, vestibular dysfunction and analgesia side-effects can all bar Group 2 driving while permitting most other work. The clinician's letter addresses the specific Group 2 criteria, references the DVLA 'Assessing fitness to drive' guide and either supports the period of incapacity or sets a return-to-LGV-driving date. CityGrip builds the medical evidence pack at intake and confirms the Group 2 angle is addressed in writing.
