# Drive Pass

> AffixIO Drive Pass unifies live MOT status, vehicle tax status and published UK clean air zone / ULEZ policy into one binary drive or do_not_drive outcome, with an exportable evidence block for employer or enforcement review.

- Live demo: https://www.affix-io.com/drive-pass/
- Parent brief: https://www.affix-io.com/llms.txt
- API: https://api.affix-io.com
- Hub (key usage): https://hub.affix-io.com/credentials/

## Inputs

1. Vehicle registration (UK VRM)
2. Travel postcode
3. Travel date (YYYY-MM-DD)

## Decision

`drive` only when MOT is valid for the travel date, vehicle tax is clear for the travel date, and the postcode either sits outside published charging zones in the demo catalogue or the vehicle is not estimated as liable for a charge.

Otherwise `do_not_drive`, with blockers listed in the evidence block.

## Data connections

- MOT and tax: DVLA vehicle records / GOV.UK vehicle enquiry
- Zones: published CAZ / ULEZ authority references matched by outward code
- Place context: OpenStreetMap Nominatim, GraphHopper Maps link, OSRM nearest-road snap
- Proofs: AffixIO circuits on api.affix-io.com (`motor_inspection_valid`, `motor_emissions_compliance`, `audit_proof`)
