Every year, millions of vehicles across the UK undergo their annual MOT test, a vital inspection designed to ensure cars are roadworthy and environmentally sound. While a clean pass is always the desired outcome, it's not uncommon for the MOT certificate to come with a list of 'advisories'. These aren't immediate failures, nor do they prevent your car from being legally driven, but they are crucial warnings that shouldn't be overlooked. Understanding what these advisories mean and, more importantly, how to check them, is fundamental to proactive car maintenance and ensuring your vehicle remains safe and reliable on British roads.

How does motorway Mot check work?

Ignoring an advisory can lead to more significant, and often more expensive, problems down the line, potentially even resulting in a failed MOT in subsequent years. This article will guide you through the process of checking your car's MOT advisories, explain common warnings you might encounter, differentiate them from actual failures, and even discuss options for financing any necessary repairs, helping you maintain your vehicle without a sudden financial burden.

What Exactly Are MOT Advisories?

An MOT advisory is a note made by the MOT tester about a component of your vehicle that is not yet dangerous or a reason for failure, but which could become a problem in the near future. Think of it as a 'heads-up' or a 'watch item'. It's an expert's opinion that something needs monitoring or attention soon. Unlike a 'fail', an advisory doesn't require immediate rectification for your vehicle to pass its MOT and be legally driven. However, it serves as a crucial warning, highlighting potential issues before they escalate into serious safety hazards or costly repairs.

For example, an advisory might state that your tyres are 'close to the legal limit' or that your brake pads are 'wearing thin'. While these components are still within legal operating parameters at the time of the test, the advisory warns you that they will likely need replacing before your next MOT. Ignoring these warnings can lead to dangerous driving conditions and, ultimately, a costly failure during a future MOT test.

Why Are MOT Advisories So Important?

While an advisory doesn't mean your car has failed its MOT, it carries significant weight for several reasons. Firstly, and most importantly, it's about safety. Advisories highlight components that are degrading and could compromise your vehicle's performance or safety features if left unaddressed. A tyre nearing its legal tread depth, for instance, will offer less grip in wet conditions, increasing the risk of aquaplaning. Worn suspension components can affect handling and braking stability. Addressing these issues promptly helps ensure your car remains safe for you, your passengers, and other road users.

Secondly, advisories are a form of preventative maintenance. By acting on them early, you can often prevent minor issues from becoming major, expensive repairs. Replacing brake pads when they are advised as 'wearing thin' is far cheaper and simpler than waiting for them to wear completely through, potentially damaging the brake discs and calipers. Similarly, addressing minor corrosion before it becomes structural can save thousands in welding and repair costs.

Finally, keeping on top of advisories contributes to your car's overall longevity and resale value. A well-maintained vehicle with a clean MOT history (meaning advisories have been addressed) is far more attractive to potential buyers. It demonstrates responsibility and care, offering peace of mind to the next owner and often commanding a better price.

How to Check Your Car's MOT Advisories

Checking your car's MOT history, including any advisories, is straightforward and highly recommended, especially if you're buying a used car or simply want to stay on top of your current vehicle's health. The primary and most convenient method, as highlighted, is using services like Regit's free MOT history check.

To use services like Regit's free MOT history check, all you typically need is your vehicle's registration number (number plate). Simply enter the registration into their online tool, and it will pull up the full MOT history for that vehicle, including pass/fail results, mileage at the time of test, and crucially, any advisories issued. This service provides a quick and easy way to access this vital information.

Alternatively, the official UK government website also offers a free service to check a vehicle's MOT history. You can find this by searching for "check MOT history" on GOV.UK. Again, you'll need the vehicle's registration number. This official source provides identical information to third-party checkers like Regit, ensuring you have access to accurate and comprehensive data directly from the Driver and Vehicle Standards Agency (DVSA).

Reviewing this history allows you to see not just the most recent advisories, but also a pattern over time. Have the same advisories been noted repeatedly? This could indicate a persistent issue that hasn't been properly addressed, or one that is slowly worsening. Understanding this history empowers you to make informed decisions about your car's maintenance.

Common MOT Advisories and What They Mean

While the specific wording can vary, certain advisories appear frequently on MOT certificates. Understanding what these mean can help you prioritise and plan for necessary repairs:

  • Tyres Close to Legal Limit: This is one of the most common advisories. In the UK, the legal minimum tread depth for car tyres is 1.6mm across the central three-quarters of the tread around the entire circumference. An advisory means your tyres are approaching this limit, usually around 2-3mm. Action: Plan to replace these tyres very soon. Worn tyres significantly reduce grip, especially in wet conditions, increasing braking distances and the risk of aquaplaning.

  • Brake Pads Wearing Thin: Your brake pads are essential for stopping your car. An advisory here indicates that the friction material on the pads is significantly worn, though still functional. Action: Have your brakes inspected by a professional. Worn pads can lead to reduced braking efficiency and, if left too long, can damage the brake discs, leading to much more expensive repairs.

  • Minor Oil/Fluid Leak: A small drip of oil, coolant, or other fluid. An advisory means it's not severe enough to be an environmental hazard or a safety risk yet, but it's noted. Action: Monitor the leak. Check fluid levels regularly. A minor leak can worsen over time, leading to significant fluid loss and potential component damage, or an MOT failure if it becomes excessive.

  • Suspension Component (e.g., Bushing) Has Slight Play: Suspension components, such as bushes or ball joints, can develop slight movement or 'play' as they wear. This isn't critical yet but can affect handling and ride comfort. Action: Keep an eye on it. If you notice clunking noises over bumps or a looser feel to the steering, have it checked. Excessive play will lead to a failure.

  • Corrosion to Underbody/Chassis (Non-Structural): Rust is a common enemy of older cars. An advisory for non-structural corrosion means there's surface rust that doesn't affect the vehicle's structural integrity or safety. Action: Consider rust treatment or underbody protection. If left untreated, surface rust can spread and eventually weaken structural components, leading to a major failure.

  • Exhaust System Minor Leak/Corrosion: Small holes or significant rust on the exhaust system. An advisory means it's not causing excessive noise or dangerous emissions yet. Action: Monitor for increased noise or fumes. A worsening leak can lead to a failed emissions test or allow dangerous exhaust gases into the cabin.

  • Headlamp Aim Slightly High/Low: Your headlights might not be perfectly aligned, causing them to illuminate the road incorrectly. Action: Have the headlamps re-aimed. Incorrectly aimed headlights can dazzle oncoming drivers or reduce your visibility, particularly at night.

  • Wiper Blades Streaky/Ineffective: Wiper blades can harden or tear over time, leaving streaks on the windscreen. An advisory means they're not clearing the screen perfectly but are still functional. Action: Replace the wiper blades. Clear visibility is crucial for safe driving, especially in rain or snow.

Advisory vs. Fail: Understanding the Difference

It's crucial to distinguish between an advisory and an MOT failure. While both are noted on your MOT certificate, their implications are very different.

An advisory is a warning. Your car has passed the MOT, and you can legally drive it away. The issue noted is not severe enough to warrant a failure at the time of the test, but it requires monitoring or attention in the near future. There's no legal deadline to fix an advisory, but it's highly recommended to address them promptly for safety and to prevent escalation.

An MOT failure means your car has a defect that makes it unsafe or unroadworthy, or that it doesn't meet environmental standards. There are now three categories of failure:

  • Minor Defect: A defect that has no significant effect on the safety of the vehicle or impact on the environment. These are similar to advisories but are more serious and will result in a pass with minor defects, meaning you don't need to fix them immediately but should do so very soon.
  • Major Defect: A defect that could affect the vehicle’s safety, put other road users at risk or have an impact on the environment. Your vehicle will fail its MOT and must be repaired immediately.
  • Dangerous Defect: A defect that constitutes a direct and immediate risk to road safety or has a serious impact on the environment. Your vehicle will fail its MOT, and you should not drive it until the defect has been rectified. Driving with a dangerous defect is illegal and extremely risky.

Here's a simplified comparison:

CategoryImplicationAction RequiredLegal to Drive?
AdvisoryPotential future issueMonitor; recommended to fix soonYes
Minor DefectMinor impact on safety/environmentRecommended to fix very soonYes (passes with minor defects)
Major DefectSignificant safety/environmental riskMust be repaired immediately for retestNo (fails MOT)
Dangerous DefectImmediate and direct risk to safetyMust be repaired immediately; do not driveNo (fails MOT)

The key takeaway is that an advisory gives you time to plan and act, while a major or dangerous defect demands immediate attention and prohibits driving the vehicle until fixed.

What to Do After Receiving Advisories

Once you've checked your MOT history and identified any advisories, the next step is crucial. Don't simply ignore them. Instead, take a proactive approach:

  1. Understand the Advisory: If you're unsure about the technical jargon, ask a trusted mechanic to explain it in simple terms. Knowledge is power when it comes to car maintenance.

  2. Prioritise Repairs: Not all advisories are equal. A tyre close to the legal limit is more urgent than a minor exhaust leak, for example. Prioritise issues that directly impact safety or could quickly escalate into a major failure. If in doubt, consult a professional mechanic for their expert opinion on urgency.

  3. Get Quotes: Shop around for quotes for the necessary repairs. Don't just go with the first garage you find. Compare prices and read reviews to ensure you're getting a fair deal from a reputable workshop.

  4. Plan for Repairs: Schedule the repairs at your earliest convenience. Delaying them can lead to worsening conditions, higher costs, or even an unexpected breakdown.

Using a service like Bumper means you don't have to compromise on safety or put off essential repairs due to budget constraints. It helps you keep your car roadworthy and reliable, protecting your investment and ensuring your safety on the road, all while managing your finances effectively.

Preventative Maintenance to Avoid Future Advisories

While some wear and tear is inevitable, many advisories can be avoided or delayed with regular preventative maintenance. Being proactive can save you money and stress in the long run:

  • Regular Servicing: Stick to your car's service schedule. A good service will identify potential issues before they become advisories, allowing for early intervention.

  • Tyre Checks: Regularly check your tyre pressure and tread depth. You can buy a cheap tread depth gauge and check them yourself. Ensure they are correctly inflated to your car manufacturer's specifications.

  • Fluid Levels: Periodically check engine oil, coolant, brake fluid, and power steering fluid levels. Top up as necessary and look for any signs of leaks under the car.

  • Lights and Wipers: Routinely check all your lights (headlights, tail lights, indicators, brake lights) are working. Test your wipers to ensure they clear the windscreen effectively. Replace bulbs or blades as soon as they show signs of wear.

  • Listen to Your Car: Pay attention to any unusual noises, vibrations, or changes in how your car drives. Early detection of issues can prevent them from escalating.

  • Cleanliness: Regularly washing your car, especially the underbody during winter months to remove salt, can help prevent corrosion.

Frequently Asked Questions (FAQs)

Can I ignore an MOT advisory?

While you can legally drive your car after receiving an advisory, ignoring it is not recommended. Advisories highlight issues that will likely worsen over time, potentially leading to a more expensive repair or an MOT failure in the future. More importantly, they can compromise your vehicle's safety.

Do advisories affect my car's value?

Yes, advisories can indirectly affect your car's value. A car with a history of unaddressed advisories, or advisories that consistently reappear, suggests a lack of proper maintenance to potential buyers. Addressing advisories shows responsibility and can help maintain your car's resale value.

How long do I have to fix an advisory?

There is no specific legal deadline to fix an advisory, unlike a major or dangerous defect. However, it's prudent to address them as soon as possible, especially if they relate to safety-critical components like tyres, brakes, or suspension.

Will my car pass its next MOT if I don't fix advisories?

Not necessarily. An advisory from one year could easily become a major or dangerous defect in the following year's MOT if left unaddressed, leading to a failure. For example, a tyre advisory for 'close to legal limit' will become a failure if the tread depth falls below 1.6mm by the next test.

Is an advisory recorded on the MOT certificate?

Yes, all advisories are officially recorded on your MOT certificate and are part of your vehicle's MOT history, which can be checked online by anyone with your car's registration number.

Do I need to get an advisory fixed at the same garage that did the MOT?

No, you are free to have any repairs related to an advisory carried out at any garage of your choice. You are not tied to the MOT test centre.
