The Short Answer
You can check a car's tax and insurance status for free online using only its registration number. The GOV.UK vehicle tax checker shows whether the car is taxed or SORN along with its MOT expiry, while the Motor Insurers' Bureau check (askMID) confirms whether a live insurance policy is on the Motor Insurance Database.
You need both tax and insurance to drive or keep a car on a public road, and checking either one takes less than a minute online for free. We run both checks whenever we buy a car, before a long trip in something that's been laid up, and any time a renewal has gone through and we want to see it's registered properly.
Below we show you how each check works, what the results look like and what to do if something doesn't add up.
How To Check If A Car Is Insured
Use the free vehicle check from the Motor Insurers' Bureau, which reads the Motor Insurance Database (MID). Most drivers still know it as askMID, and the MIB's guide to checking your vehicle's insurance links to the current service.
- Open the MIB vehicle check and enter the car's registration number.
- Accept the terms and run the check.
- Read the result, which shows the car as either insured or not insured.
The check doesn't show any personal details or what type of cover is in place. It only confirms that a live policy exists for that registration, which is the same database the police and other professionals can access.
Why A Car Shows As Not Insured
Seeing "not insured" for a car you know is covered is alarming, but there's normally a simple reason behind it:
- A typo: One wrong character in the registration brings up a different car or no car at all.
- A mistake on the policy: The insurer may have keyed the wrong registration when setting up the cover.
- A delay in updating: A new or renewed policy can take several days to appear on the database.
The MIB says that if you've just bought or renewed a policy, you should wait seven days and search again, keeping your policy documents with you in the car until it shows up. If the result is still wrong after that, call your insurer and ask them to correct it.
How To Check If A Car Is Taxed
The GOV.UK vehicle tax checker is free and only needs the registration number. Enter it, confirm the vehicle details it brings up, and the result tells you whether the car is taxed or registered as off the road, along with its MOT status.
You get a little more from this check than from the insurance one, as it shows the date the tax is due and when the MOT expires. That makes it handy for spotting a lapsed MOT on a car you're thinking of buying, and our guide on how long an MOT takes helps if you need to get one booked.
If you've just taxed the car, GOV.UK says the records can take up to 2 working days to update, so don't panic if an old status shows the same afternoon.
What SORN Means On A Tax Check
SORN means the car has been declared off the road with DVLA. It can stay that way if you're keeping it in a garage or on private land, but it can't be used on a public road until it's taxed again, apart from driving it to a pre-booked MOT.
To put it back on the road, tax it through GOV.UK using a recent tax reminder letter, the V5C log book in your name, or the green new keeper slip if you've just bought it. If you've lost the log book, our guides to taxing a car without a V5 and getting a replacement log book explain the options, and there's more background in our guide to what a SORN is and how it works.
What Happens If You Drive Without Tax Or Insurance
No insurance is the more serious of the two. GOV.UK's page on driving without insurance says police can give you a £300 fixed penalty and 6 penalty points, and if it goes to court you face an unlimited fine and a possible driving ban. The police can also seize the car.
An untaxed car can be clamped or impounded, and DVLA can follow up with financial penalties and court action. Insurance and tax are separate, so being insured doesn't cover you for a lapsed tax payment or the other way round.
Cars That Don't Pay Vehicle Tax
Some cars pay nothing, but GOV.UK's list of vehicles exempt from vehicle tax makes it clear they still have to be taxed, even at a zero rate. The main exemptions are:
- Historic vehicles: Classics built before the cut-off date GOV.UK sets can be taxed in the historic class.
- Disabled drivers: One vehicle at a time can be exempt for eligible disabled people, claimed when you tax it.
Electric cars no longer qualify. They've had to pay vehicle tax since 1 April 2025, so an EV that was taxed at a zero rate in the past now needs paying for like any other car.
When It's Worth Running Both Checks
Check both before you buy a used car, so you know whether you can drive it home or need to sort tax and cover first. Our guides to the best places to buy a used car and changing the ownership of a car online cover the rest of that process. Tax doesn't follow the car to a new keeper, so plan to tax it yourself the day you collect it.
It's also worth a quick check after any renewal, after changing cars on the same policy and before taking a car out of storage. It takes a minute and saves a roadside conversation with the police.
Car Tax And Insurance Check Questions
Is It Free To Check If A Car Is Insured?
Yes. The Motor Insurers' Bureau check, which most people know as askMID, is free for checking a vehicle and only needs the registration number. It tells you whether a live policy is recorded on the Motor Insurance Database, but it won't show who the policy belongs to or what level of cover it gives.
How Long Does It Take For New Insurance To Show On askMID?
A new or renewed policy can take several days to appear on the Motor Insurance Database. The MIB advises waiting seven days and checking again, and keeping your policy documents in the car in the meantime. If the car still shows as not insured after that, ask your insurer to check the registration on the policy.
Can I Check If Someone Else's Car Is Taxed?
Yes. The GOV.UK vehicle tax checker works for any registration, so you can check a car you're thinking of buying or one that's been parked on your street for months. It shows whether the car is taxed or SORN and when its MOT expires, without revealing who owns it.
Does Vehicle Tax Transfer When You Buy A Car?
No. Vehicle tax doesn't pass to the new keeper, so you need to tax the car before you drive it away. You can do this online straight away using the green new keeper slip from the V5C, and the seller gets a refund for any full months left once they tell DVLA about the sale.
Do Electric Cars Need To Be Taxed?
Yes. Electric cars have had to pay vehicle tax since 1 April 2025, so they're no longer exempt. Even vehicles that do still qualify for an exemption, such as historic cars, have to be taxed at a zero rate rather than left untaxed, so the record shows the car is legal to use.
Can You Drive A SORN Car To An MOT?
Yes, you can drive a SORN car on the road to a pre-booked MOT test, but nowhere else. It still has to be insured for that trip. Once it passes, you can tax it online and use it normally, and the tax record can take up to 2 working days to update.
What Happens If You're Caught Driving Without Insurance?
The police can give you a £300 fixed penalty and 6 penalty points, or the case can go to court, where the fine is unlimited and you can be disqualified from driving. The car can also be seized. Checking the database after every renewal is the simplest way to make sure your cover has gone through.
