Why this schema exists

GOV-986 ("GovSchema Standard Research") audited the registry's coverage across the 6 focus verticals (DMV, Business Formation, Visa, Passport, Taxes, National ID & Civic Documents) against all 12 scoped jurisdictions (US, GB, IE, CA, NZ, AU, DE, SG, FR, NL, IN, EU). The matrix is close to saturated — every jurisdiction has at least one published schema in every vertical except two already-recorded infeasible gaps (NL Visa — Schengen duplicates the FR schema, the MVV national visa is 200+ fragmented forms per [[gov859-nl-identity-card-and-5of6]]; EU-level anything — ETIAS is not yet operational). Within DMV specifically, the vertical's own naming ("Tag, Title, Registration, Drivers License, IDL, and CDL") flagged a narrower real gap: this registry's only commercial/vocational driving-licence schema was us/ca/dmv/commercial-drivers-license-application (US, one state). No other jurisdiction had a CDL-equivalent schema — every other DMV/Drivers-License entry (GB's own driving-licence-renewal-photocard and driving-licence-first-provisional included) covers only the standard car (category B) licence. The UK's HGV/PCV provisional-entitlement process is a clean, non-gated, well-documented match: same authority (DVLA) as two already-published GB schemas, a by-post-only paper-form process (matching this registry's general preference for non-interactive sources), and explicitly named as the CDL-equivalent leg of the DMV vertical.

Sources examined

• Document (id, version): gb/dvla/lorry-bus-provisional-licence / 1.0.0
• Spec version: GovSchema 0.3.0
• Authority: Driver and Vehicle Licensing Agency (DVLA); tests themselves are administered by the Driver and Vehicle Standards Agency (DVSA), not modelled here (out of scope, see below).
• Primary source: gov.uk guide "Become a qualified heavy goods vehicle (HGV) or bus driver" — fetched via the gov.uk content API (https://www.gov.uk/api/content/become-lorry-bus-driver, HTTP 200, no bot-block), 2026-07-04. This guide is a multi-part document; the parts read in full were "Getting qualified", "Applying for a provisional HGV or bus licence", and "Fees".
• Secondary source: gov.uk guide "Driving licence categories" (/api/content/driving-licence-categories), fetched the same way — used only to confirm the closed set of vocational category codes (C1, C1E, C, CE, D1, D1E, D, DE) referenced by licenceCategoryApplied's description; the category weight/passenger-seat/trailer definitions themselves are not repeated as schema data (out of scope, purely descriptive).
• No downloadable form found. Unlike ie/revenue/vehicle-registration-tax-vrt (a genuine fillable AcroForm PDF), forms D2 and D4 are Post-Office-only — the same access pattern already recorded for form D1 in the sibling gb/dvla/driving-licence-first-provisional's VERIFICATION.md. A search of gov.uk's own site search API (/api/search.json) for "D2 form", "application for a driving licence D2", and "driving licence D2 publication" surfaced no government/publications/* PDF result for D2 or D4 (contrast with car-licence form D1, which likewise has no PDF; this registry has not found any DVLA driving-licence application form published as a directly downloadable PDF, only vehicle-side forms like V5C/V11). The sub-page URL /become-lorry-bus-driver/applying-for-a-bus-or-lorry-provisional-entitlement linked from "Getting qualified" 303-redirects back to the same parent guide (confirmed via the content API), so it carries no additional detail beyond what "Applying for a provisional HGV or bus licence" already states.

What was confirmed against the source

| Source element | Field(s) / document(s) | |---|---| | "Getting qualified": "have a full car licence" | fullCarLicenceHeld | | "Getting qualified": "be over 18 - but there are some exceptions" | dateOfBirth | | "Filling in form D2" category/entitlement table (C1→C1; C or C1+E→C1,C1+E,C,CE; D or D1→D1,D1+E,D,DE) | licenceCategoryApplied | | "How to apply": "fill in these 2 forms: a D2 application form; a D4 medical examination report - this must be filled in by a doctor" | d2ApplicationForm, d4MedicalExaminationReport, d4MedicalReportCompleted | | "Filling in form D4": GP, optician (eyesight section), or private medical firm; may be charged | d4MedicalReportCompleted description | | "Send the forms": "Send both forms and your photocard driving licence to DVLA. There's no application fee." | currentPhotocardLicence | | "Send the forms": "If you have a paper driving licence you must include a passport-style colour photo and original identity documents." | currentLicenceFormat, passportStyleColourPhoto, originalIdentityDocuments | | "Fees" → "Provisional licence": "It's free to apply for a provisional heavy goods vehicle (HGV) or bus licence." | no fee/payment field modelled (confirmed there is none, not an omission) | | "Driving licence categories" — C1/C1E/C/CE/D1/D1E/D/DE codes | licenceCategoryApplied enum values |

Honesty flags (deliberate, recorded rather than glossed over)

• No official D2/D4 field-by-field specification exists to check against. Both forms are Post-Office-only, exactly like form D1 in the sibling gb/dvla/driving-licence-first-provisional. lastName and firstNames are modelled by analogy with that sibling's applicant-detail fields (every DVLA licence application collects a name at minimum) rather than from an independently confirmed D2 field list — flagged in each field's own sourceRef, not presented as equivalent rigor to the source-confirmed fields.
• The "some exceptions" to the age-18 rule are not modelled. The source links to a separate vehicles-you-can-drive page for the detail (e.g. narrower age rules for certain armed-forces/exempt-vehicle cases); this schema models only the general rule via dateOfBirth's description, with no automated eligibility transition attached to it (the same discipline the sibling schema used for its own dateOfBirth field — only the boolean eligibility gates, not the raw date, drive a steps[] transition).
• d4MedicalReportCompleted is a single gating boolean, not the underlying medical questionnaire. The D4 form's actual medical questions (the notifiable-conditions list DVLA's separate condition-specific questionnaires would ask) were not sourced and are out of scope — the same modelling choice the sibling schema made for its own medicalConditionDeclared field.
• Driver CPC tests, the post-CPC full licence, renewal, and requalification are explicitly out of scope. The source guide covers all of these under one URL, but only the "Applying for a provisional HGV or bus licence" section was modelled — a distinct process ("Renew or change a lorry or bus licence", /renew-lorry-bus-coach-licence) already exists as a separate gov.uk service and would be a natural v2/sibling schema, not folded in here.
• No live DVLA transaction was tested. D2/D4 are paper forms posted to DVLA Swansea; there is no online application channel for this specific service (unlike the sibling first-provisional schema, which has both an online and a by-post channel). A worked walkthrough with representative mock values is given below and in conformance/gb/dvla/lorry-bus-provisional-licence/1.0.0/ in place of a live test run.

Worked example (mock data, not a live submission)

Scenario: a 24-year-old full car-licence holder applying for a provisional Category C (large lorry) entitlement, holding a current photocard licence.

| Field | Mock value | |---|---| | fullCarLicenceHeld | true | | dateOfBirth | 2002-03-14 | | lastName | KOWALSKI | | firstNames | TOMASZ | | licenceCategoryApplied | c | | currentLicenceFormat | photocard | | d4MedicalReportCompleted | true |

Walking this data through the modelled steps[]: fullCarLicenceHeld is true, so eligibility falls through to applicant_and_category (no exit triggered) → medical_and_licence_format, the final step. Because currentLicenceFormat is photocard, documents[].currentPhotocardLicence is correctly required and passportStyleColourPhoto / originalIdentityDocuments are correctly not required — a self-consistency check of the schema's own conditional-requirement logic (also run mechanically — see conformance/gb/dvla/lorry-bus-provisional-licence/1.0.0/), not a substitute for a live DVLA transaction — see the honesty flag above.

Path to verified

1. Obtain an official, independently-published D2 and D4 field list (a DVLA FOI request or a genuine scanned copy, rather than the current guidance-page-only sourcing) to confirm lastName/firstNames and add any additional applicant-detail fields the paper forms actually collect.
2. Confirm the age-18 "some exceptions" carve-out against the vehicles-you-can-drive page and decide whether it warrants a modelled field.
3. Consider a sibling gb/dvla/lorry-bus-licence-renewal schema for the separate 5-yearly (or annual, over 65) renewal process (/renew-lorry-bus-coach-licence), explicitly out of scope here.
