What Is The Motor Insurance Database (MID)?
The Motor Insurance Database (MID) is a central register of every insured vehicle in the UK, managed by the Motor Insurers’ Bureau (MIB) on behalf of the insurance industry.
Police use the MID alongside automatic number plate recognition (ANPR) cameras to identify uninsured vehicles in real time. If your motor trade insurance policy covers multiple vehicles, keeping every one of them on the database is your responsibility.
This guide covers how the MID works, which vehicles you need to add, how to update your records, and what happens if you get it wrong.
Valid insurance isn’t enough if your vehicle doesn’t appear on the MID. Police check the database via ANPR, not your policy documents, so a missing record can get a fully insured vehicle seized. Add every vehicle the day it arrives and remove it the day it leaves.
Check your vehicles show on askMID and make sure your provider offers portal access when you compare motor trade insurance quotes.
What is the motor insurance database?
The MID holds details of every vehicle insured to drive on UK roads. Insurers, brokers, and fleet managers upload policy data to the database, and it is available to the police, DVLA, and local authorities 24 hours a day.
Who runs the MID?
The Motor Insurers’ Bureau (MIB) manages the database under a legal framework set out in the Road Traffic Act 1988. Insurers must add private car policies within seven days and commercial or motor trade policies within 14 days.
Records stay on the database for seven years after a policy ends. The MIB also handles claims from victims of uninsured and untraced drivers.
Why was the MID created?
Before the MID, police had no quick way to verify whether a vehicle was insured. The database was introduced alongside the Continuous Insurance Enforcement (CIE) scheme, which makes it an offence to keep a registered vehicle without insurance unless it has a Statutory Off Road Notification (SORN).
Why does the MID matter for motor traders?
Motor traders handle dozens of vehicles at any given time. If even one vehicle is missing from the MID, it can be flagged by ANPR cameras and seized by police during a routine check.
What are the real-world risks?
A trader driving an unregistered vehicle on a test drive or delivery run risks a fixed penalty of £300 and six points on their licence. In more serious cases, courts can impose an unlimited fine and driving disqualification.
Even if you hold valid road risk insurance, a vehicle that is not on the MID can still be stopped. The police check the database, not your policy documents.

Which vehicles do you need to add to the MID?
You must add every vehicle covered by your motor trade policy that is taxed or driven on public roads. This includes stock vehicles, customer cars in your care, and any courtesy or hire vehicles.
| Vehicle type | Must add to MID? | Notes |
| Taxed stock vehicles | Yes | Add when acquired, remove when sold |
| Customer vehicles in your care | Yes | Courtesy cars, hire vehicles, repairs |
| Trade plates | Yes | Register alongside your policy |
| Leased or owned business vehicles | Yes | Any vehicle used under your policy |
| Untaxed stock (SORN) | No (recommended) | Best practice to add them anyway |
| Vehicles on private land only | No | Never driven on public roads |
What about trade plates and untaxed stock?
Trade plates themselves should be registered on the MID. Untaxed stock vehicles that you only move on trade plates do not legally need adding, but it is best practice to include them.
If you run a car dealership with a forecourt, the simplest approach is to add every vehicle as soon as it arrives and remove it the day it leaves. This avoids gaps that ANPR cameras could catch.
Which vehicles are exempt?
Vehicles with a valid SORN do not need to be on the MID because they cannot legally be on public roads. Vehicles stored on private land that are never driven also fall outside the requirement.
How do you update the MID?
Most motor trade insurers give you direct portal access so you can add and remove vehicles yourself. Your insurer will set this up when your policy starts, and you can usually log in within 24 hours of buying cover.
What information do you need to submit?
For each vehicle you add, you will need your motor trade policy number, the vehicle registration mark (VRM), the date the vehicle was added to your policy, and the date it was removed.
If you are a part-time trader with a smaller policy, your insurer may handle MID updates on your behalf. Check your policy documents to confirm who is responsible.
How quickly do updates appear?
Insurers are legally required to submit data within 14 days, but most updates appear on the database within 48 hours. If you add a vehicle through your portal on a weekday morning, it will typically show on the MID by the next working day.
What happens if you don’t update the MID?
Failing to keep the MID up to date can result in an Insurance Advisory Letter (IAL), a fixed penalty notice, or vehicle seizure by police. The consequences apply even if your insurance policy is valid.
What penalties can you face?
The first warning is usually an IAL posted to the registered keeper. If the vehicle is still showing as uninsured after 28 days, the DVLA can issue a £100 fixed penalty.
On the road, police can issue a £300 fixed penalty and six licence points for driving without insurance. They can also seize the vehicle under section 165A of the Road Traffic Act 1988.
For motor traders, losing a stock vehicle this way is an avoidable cost.

How do you check if a vehicle is on the MID?
Anyone can check whether their own vehicle appears on the MID for free using the askMID service run by the MIB. You just need the vehicle registration number.
Can you check someone else’s vehicle?
You can check a third party’s insurance status through the askMID website after an accident. A small fee may apply for third-party checks.
If you need a copy of the personal data held about you on the MID, you can submit a Subject Access Request (SAR) to the MIB. Under UK GDPR, there is no fee for this.
What should you do if your vehicle is missing?
Contact your insurer immediately and ask them to update the MID as a priority. Until the record appears, avoid driving the vehicle on public roads.
This applies to every type of trader. A mobile mechanic, recovery operator, or motorcycle dealer driving an unregistered vehicle risks the same penalties as a car dealer.
