How to get a formal collision extract from Milton Keynes
The council's road safety or traffic team holds the full police records for its area. A formal extract can add what the published data leaves out: contributory factors, the officer's description of each collision and the current year's provisional records. Developers, consultants and solicitors usually pay for it.
Check Milton Keynes's website for current fees, or contact its road safety team. Councils usually charge for extracts and send a quote before they start.
