UK Road Accident Data — National Highways

UK Traffic Updates archives every collision, overturned vehicle incident, and vehicle fire recorded by National Highways across England's motorway and strategic road network. Records include timestamps, road closures, duration, severity, and location data.

If you were involved in an accident on a UK motorway or A-road, this archive can help you find the incident record. Our instant evidence reports come in five tiers: 99p Micro Certificate (instant timestamp proof), £5.99 Delay Certificate (HR or insurance proof of delay), £14.99 Standard Report (full incident details with weather and road context), £49.99 Premium Court-Ready Report (complete evidence pack with full timeline, traffic impact analysis, emergency services detection, blackspot history, and meteorological conditions), and the £59.99 Crash Day Pack (Premium Report + Delay Certificate + Risk Report bundled — saves £3.98 vs buying separately). Reports generate within seconds, not months.

For serious collisions and court cases, our £199 Premium Plus Expedited Service includes a full Premium Report, human verification of every data point within 4 working hours, and priority handling. Premium Plus is an evidence service, not legal advice — UK Traffic Updates is not a law firm, and we do not refer you to one.

The Premium Report is built for legal proceedings and insurance disputes — section references, citations under the Road Traffic Act 1988, and evidence-grade formatting, with the National Highways reference number and the exact time we received the data. Take it to any SRA-regulated solicitor you choose; we don't send you to anyone and we don't pass on your details.

Important Information

UK Traffic Updates is a traffic information and incident monitoring service. We are not a law firm, solicitors, or a claims management company. We do not provide legal advice, assess claims, or manage any part of the legal process.

Our role is limited to connecting individuals who may have been involved in a road traffic incident with independent, regulated solicitors who specialise in personal injury claims. Any solicitor you are connected with operates independently of UK Traffic Updates and is authorised and regulated by the Solicitors Regulation Authority (SRA).

UK Traffic Updates may receive a referral fee from the solicitor in connection with any introduction made through this service. This does not affect the amount of compensation you receive or the service provided to you by the solicitor.

Submitting your details through this form does not constitute a legal claim and does not create a solicitor-client relationship with UK Traffic Updates. You are under no obligation to proceed with any claim after being contacted. You are also free to seek independent legal advice from a solicitor of your own choosing at any time.

The compensation figures shown on this page are general guidelines based on the Judicial College Guidelines and are not guarantees of any specific outcome. Every claim is assessed on its own facts and circumstances.
