The Motor Insurance Database (MID) is the UK’s central electronic record of every motor insurance policy in force, operated by the Motor Insurers’ Bureau and used for police enforcement of the compulsory motor insurance regime, for the Continuous Insurance Enforcement keeper-checking process and for public verification of cover.
Category: Motor Also known as: MID, MID database, askMID First codified: Established 1999 to satisfy the EU Fourth Motor Insurance Directive (2000/26/EC); placed on a statutory enforcement footing by the Road Safety Act 2006 Related legislation: Road Traffic Act 1988 section 144A; Motor Vehicles (Insurance Requirements) Regulations 2011 Apex Wiki link: /wiki/motor-insurance-database/
The Motor Insurance Database (MID) is the central electronic record of all motor insurance policies in force for vehicles kept or used in the United Kingdom. It is operated and maintained by the Motor Insurers’ Bureau (MIB), the trade body to which all UK motor insurers are obliged to belong, and is funded by a per-policy levy on motor insurers [1].
Every UK motor insurance policy must be uploaded to the MID by the issuing insurer within seven days of inception, renewal or material change, recording vehicle registration mark, policy details, policyholder name, named drivers and dates of cover. The MID is queried in real time by police automatic number plate recognition (ANPR) systems to identify uninsured vehicles, by the Driver and Vehicle Licensing Agency (DVLA) for the Continuous Insurance Enforcement compliance check, by claimants establishing the identity of an insurer of a third-party vehicle, and by members of the public via the askMID public lookup service.
The MID was established in 1999 to implement the EU Fourth Motor Insurance Directive (2000/26/EC), which required member states to maintain a central information centre to facilitate cross-border claims [2]. Its enforcement role was significantly expanded by the Continuous Insurance Enforcement regime introduced by sections 22 and 23 of the Road Safety Act 2006 [3].
The MID’s UK enforcement basis is set by the Road Traffic Act 1988 as amended. Section 144A RTA 1988 (inserted by section 22 of the Road Safety Act 2006) creates the offence of being the registered keeper of an uninsured vehicle; the MID is the dataset by reference to which compliance is verified [3]. The Motor Vehicles (Insurance Requirements) Regulations 2011 (SI 2011/1120) set the procedural framework, including the time limits within which insurers must update the MID [4].
The MID is operated by the Motor Insurers’ Bureau under arrangements with the Secretary of State for Transport, with the Department for Transport as the policy sponsor. The MIB is a private company limited by guarantee whose members are all UK-authorised motor insurers; membership is a condition of motor insurance authorisation under Part 4A of the Financial Services and Markets Act 2000 by virtue of the MIB membership requirement imposed by the Secretary of State [1].
The MID also serves as the UK’s information centre for the purposes of the Sixth Motor Insurance Directive 2009/103/EC (consolidating the Fourth Directive and others), allowing victims of cross-border accidents to identify the insurer of a foreign vehicle and to pursue claims through the Green Card system [5].
Data protection compliance is governed by the UK General Data Protection Regulation and the Data Protection Act 2018. The Information Commissioner’s Office is the supervisory authority for personal data processing on the MID; the MIB publishes a privacy notice describing the purposes of processing [1].
For an insurer issuing a policy, the workflow is:
The DVLA cross-matches the vehicle keeper register against the MID; vehicles registered as having a keeper but appearing not to be insured (with no SORN) trigger an Insurance Advisory Letter (IAL) sent to the registered keeper, followed by enforcement action under the Continuous Insurance Enforcement regime if not resolved [3].
Police use the MID via ANPR cameras mounted at roadsides and on patrol vehicles. An uninsured vehicle is flagged in real time; the police can stop the vehicle, charge the driver under section 143 RTA 1988 and seize the vehicle under section 165A RTA 1988.
Members of the public can use the askMID lookup at askmid.com to check whether a vehicle is insured, free of charge for up to five searches per day on the holder’s own vehicle. A separate AskMID for the Roadside service allows drivers involved in an accident to identify the insurer of a third-party vehicle for a small fee.
For brokers, prompt and accurate MID upload is a regulatory expectation: failure to upload can leave a policyholder exposed to enforcement action, even though cover is in force. The MIB publishes MID compliance scores by insurer and applies fines for late or inaccurate data [1].
The MID has evolved through several technical iterations since 1999. Originally a batch-uploaded record, it became near-real-time in the mid-2000s. The ‘MIDAS’ policing interface and the askMID public service were added in stages. The Continuous Insurance Enforcement regime in 2011 transformed the MID from a record-keeping resource into an active enforcement dataset [3].

In Northern Ireland the MID covers vehicles registered there as well, applying the equivalent Road Traffic (NI) Order 1981 regime.
An illustrative example: a private individual buys a vehicle from a dealer on a Friday afternoon. The dealer issues seven days’ free motor insurance cover, valid from the time of purchase. The buyer drives away.
On Saturday morning the police ANPR system queries the vehicle’s registration against the MID. The cover has not yet been uploaded (the insurer has up to seven days under SI 2011/1120 [4], and weekends often delay batch uploads). The ANPR returns a ‘no insurance’ response.
The police stop the vehicle. The buyer presents the dealer’s certificate of insurance issued at the point of sale. The police accept the certificate as evidence of cover under section 165 RTA 1988 [6] and do not pursue an offence; the MID is updated within the seven-day window and the matter is closed.
In a contrasting example, a registered keeper has cancelled their policy and not declared SORN. The DVLA’s MID cross-check identifies the gap and sends an IAL. No action is taken. After 14 days the keeper is sent a fixed penalty notice of £100; if unpaid, the matter proceeds to prosecution under section 144A RTA 1988 [3]. Figures are illustrative only.
