Legally, there's no time limit to fix MOT advisories as they are warnings, not failures. However, it's wise to get them fixed promptly as they can become dangerous, illegal, or cause an MOT fail the following year.
That's a cracking question, and one I hear in the workshop almost every day. When I hand a customer their MOT pass certificate (the VT20 form) and it has a few 'advisories' listed, I often see a flicker of worry. They're relieved the car has passed, but they immediately wonder, "What does this mean? Am I on the clock? Do I have 30 days to sort this?" Let's clear the air right away: legally, there is no deadline or time limit to fix an MOT advisory. An advisory is not a defect; it's a formal heads-up from the MOT tester (me!) that a component is showing signs of wear or is getting close to the legal limit. Your MOT certificate is valid for the full year, and you haven't broken any rules by driving away with advisories listed. It's a pass certificate, after all. However, and this is the crucial part, that doesn't mean you should ignore them. An advisory is a prediction. It's my professional judgement, based on the DVSA's strict criteria, that something will likely need attention before your next MOT. Ignoring it could not only lead to a failure next year but, more importantly, could compromise your car's safety. Your responsibility to keep your vehicle in a roadworthy condition is a continuous one, day in, day out, and advisories are a big clue about where to focus your attention.
The official UK MOT rule
As an MOT tester, my bible is the DVSA's 'MOT Inspection Manual'. It's what we use to decide if a component passes, fails, or warrants an advisory. The manual makes it very clear what an advisory is for. It states that testers can add advisories for items that are close to, but have not yet reached, the failure criteria. The purpose is to inform you, the vehicle's owner, of these items so you can monitor them and arrange for repairs. Let's be specific. Under Section R of the Manual, 'Recording test results', it outlines three main outcomes: 1. **Pass:** The vehicle meets the minimum legal stan
How testers actually assess this
When I'm under a car on the ramp, the process isn't about looking for reasons to fail it; it's about systematically checking each component against the standards in the manual. Many of these checks result in a clear pass or fail, but some live in a 'grey area'. This is where experience and professional judgement come in, and where advisories are born. Take corrosion, for example. The rules are very specific about corrosion within 30cm of a 'prescribed area' like a seatbelt mount, suspension fixing, or steering rack mount. If I can press my thumb on the metal and it flexes, or if I tap it with
Common scenarios — pass, advisory or fail?
To make this really clear, let's walk through some of the most common items I see every week and break down when they pass, get an advisory, or fail outright. **Tyres** * **Pass:** Good tread depth across the central three-quarters of the tyre (e.g., 4mm), no cuts, bulges, or perishing on the sidewalls. * **Advisory:** Tread depth is getting close to the legal limit. For example, a tyre at 2.0mm. I'd record it as 'Nearside front tyre worn close to legal limit'. Or, slight age-related cracking (perishing) on the sidewall, but no cords are exposed. * **Fail (Major Defect):** Tread depth is 1.6mm
What to do if you're worried before your test
A bit of pre-MOT anxiety is normal, but you can turn that worry into action. Spending 15 minutes doing some simple checks yourself can save you the hassle and cost of a fail. In my experience, most failures are for simple things that are easy to spot and fix. Here’s my examiner's pre-test checklist: 1. **Lights:** This is the number one cause of failures. Ask a friend to help you or park facing a garage door or shop window at night. Check all your indicators, sidelights, dipped beams, main beams, brake lights (including the high-level one), and your number plate lights. A blown bulb is often a
What happens if you do fail
Okay, so the worst has happened, and I've had to give you a VT30 'Refusal of an MOT Certificate'. Don't panic, it feels worse than it is, and there's a clear process to follow. The fail certificate will list any 'Major' or 'Dangerous' defects. The key difference is how it affects your ability to drive the car. * **Major Defect:** If your previous MOT is still valid (i.e., you're not testing on the expiry date), you are legally permitted to drive your car away to a place of repair or to a pre-booked MOT appointment. However, you must get the defect fixed. * **Dangerous Defect:** This is serious
Will my insurance be invalid if I don't fix MOT advisories? — Not directly. An advisory isn't a declaration of unroadworthiness, so your insurance isn't automatically void. However, all policies require you to keep your car in a roadworthy condition. If you have an accident caused by a part that was listed as an advisory (like a worn tyre) and you hadn't fixed it, your insurer could argue you were negligent. They might then dispute or refuse your claim. It's
Can I sell a car with outstanding MOT advisories? — Yes, you absolutely can. There is no law against selling a car with advisories. However, you must be transparent with the buyer. All MOT history, including advisories and failures, is publicly available online for free using the vehicle's registration number. A smart buyer will check this. Not disclosing advisories is bad practice and could lead to legal disputes later. A car's price should always
Do police check MOT advisories at the roadside? — Police ANPR (Automatic Number Plate Recognition) systems will tell them if your car has a valid MOT, tax, and insurance, but they won't see the specific advisories. However, if they pull you over for an observable fault – like a cracked brake light or a noisy exhaust – and that exact item was on your last MOT as an advisory, it serves as strong evidence that you were aware of a developing fault an
