What is the primary function of the Motor Insurance Database (MID)?

The primary function of the Motor Insurance Database (MID) is to provide details on all registered UK vehicles. This database is essential for insurers, as it helps them check whether a vehicle is insured and aids in the enforcement of motor insurance laws. The MID contains information about insurance policies that are currently active, including details about the vehicle, the policyholder, and the insurance provider. This access to up-to-date information ensures that both law enforcement and insurers can efficiently address issues related to uninsured vehicles, enhancing overall road safety.

The other choices, while important in their own contexts, do not accurately represent the main purpose of the MID. The database is not primarily designed for storing information about known fraudsters, assisting in business continuity plans, or facilitating mediation in disputes; these functions are typically handled by other systems or organizations within the insurance and legal sectors.
