Most drivers breathe a sigh of relief when their car passes its MOT, but the moment they read the “Advisory Notices” section, that relief fades. Advisories sit in a strange middle ground. They’re not failures, yet they’re not clean passes either. They don’t stop your car from being road-legal, but they absolutely matter. What this really means is that MOT advisories are warnings, early indicators of repair needs that are coming your way. And when you take them seriously, future MOT tests become easier, cheaper, and far less stressful.
This guide walks through everything you need to know in clear, simple language: what advisories are, how MOT testers decide them, what they mean for your car, whether you should repair them, how they affect resale value, and how garages like GForce Tyres can help you manage them before they turn into failures.
What MOT Advisory Notices Actually Are?
During an MOT, the tester checks your vehicle against DVSA safety and emissions standards. The outcome can be a pass, a pass with advisories, or a fail. If your car gets advisories, it means the tester spotted parts that are worn, aging, or deteriorating, but not to the point of failing the test.
Advisories often involve brakes beginning to thin, tyres approaching their legal limit, suspension components showing age, minor exhaust leaks, light corrosion, or small windscreen chips. These issues don’t break DVSA rules yet, but they’re moving in that direction. So the advisory acts as a hint: “Fix this soon or expect trouble.”
Many drivers ignore advisories because the car technically passed. But advisories are one of the strongest predictors of what will fail next year, which is why understanding them is crucial.
Why MOT Testers Add Advisory Notes?
Advisories are part of the DVSA’s transparency system. Testers add them when something isn’t perfect but hasn’t crossed the line into a fail. A brake pad may still have legal thickness but be visibly worn. A tyre might still be legal but close to the 1.6mm limit. A suspension bush might be starting to split but hasn’t developed excessive play.
The tester’s job is not only to assess whether the car is legal today but also to warn you of components that are on a downward trend. Advisories are clues, and they help you avoid sudden breakdowns, unexpected repair bills, and next-year MOT shock.

Common Types of MOT Advisories
While every car is different, advisories tend to appear in the same areas. Tyres are one of the most frequent advisory items because they wear gradually and often reach borderline levels before the MOT date. When a tester writes something like “tyre worn close to the legal limit” or “sidewall cracking starting to appear”, it means the tyre is still usable but not far from becoming a safety issue.
Brakes
Brakes are another common advisory category. Pads wear down slowly, discs corrode over winter, and brake balance can begin to drift. A tester may write “brake pads wearing thin” or “brake discs pitted but not seriously weakened.” These notes tell you the braking system is still functional but won’t stay that way for long. if you want car brake repair in aldershot than visit gforce tyres.
Suspension
Suspension also generates a lot of advisories. A shock absorber might be misting, a ball joint may have slight play, or a bush may be starting to degrade. None of these issues stop the car from passing the MOT, but they often turn into next year’s failures if left untouched.
Exhaust
Exhaust systems are another area where advisories pop up. An exhaust may have a light blow or rust that isn’t yet severe enough to fail. Over time, these small issues tend to worsen quickly.
Body Work
Bodywork, corrosion and small leaks — like minor oil misting — also appear frequently as advisory notes. These are not serious yet, but they don’t improve with time.
How Serious Are Advisory Notices?
The seriousness varies depending on the component. Some advisories are mild, like slightly split wipers or a minor windscreen chip. Others are far more important, like brake and tyre wear or early suspension deterioration. The safest approach is to judge advisories based on risk. Anything involving tyres, braking, steering, or suspension deserves attention much sooner than a minor oil weep or surface rust.
An advisory is essentially a timer. Some timers run slowly, others run fast. Your job is to know which ones can wait and which ones shouldn’t.
Do Advisories Affect Your MOT Result?
No. If your car has advisories, it still passes the MOT. You can legally drive it for the next twelve months, and your insurance remains valid. But advisories do stay on your MOT history, permanently for that test cycle. That means anyone who checks your car’s MOT records online will see them, including buyers, garages, traders, and sometimes insurers.
Advisories don’t block a pass, but they leave a trail. A long list of repeat advisories signals poor maintenance, which affects future MOT performance and your car’s resale value.
Should You Fix MOT Advisories Immediately?
You’re not required by law to fix advisories immediately, but it’s almost always a smart idea. Advisories tend to move in one direction, towards becoming failures. When you repair them early, you make next year’s MOT easier, avoid last-minute panic, and reduce the risk of breaking down on the road.
For example, a tyre that is “close to the legal limit” might be legal today but unsafe in heavy rain. Brake pads that are “wearing thin” might work now but could become dangerously weak in a few months. Suspension bushes that are starting to split might pass today but fail the next MOT without warning.
Fixing advisories early gives you control. Waiting until the next MOT usually forces you to repair everything at once, often right when you’re not expecting it.
How MOT Advisories Impact Resale Value
Buyers today check the MOT history before viewing a car. If they see persistent advisories, especially ones related to tyres, corrosion, or braking, they assume the car hasn’t been looked after properly. This reduces trust, and negotiation becomes harder.
However, when you can show invoices for advisory repairs or a clean MOT history the following year, it sends the opposite message: the vehicle has been maintained responsibly. Cars with a responsible maintenance record always sell better and faster.
How Testers Decide What Counts as an Advisory?
MOT testers use the DVSA inspection manual, which gives precise guidelines for every component. A brake pad must be above a minimum thickness to pass. Tyres must have at least 1.6mm of tread across the central three-quarters. Suspension components must not have excessive play.
If something is still technically legal but close to the threshold, the tester marks it as an advisory. It’s not a guess. It’s an assessment based on training, measurement, and experience.
This system ensures consistency. Whether you test your car in Scotland or Surrey, the advisory system works the same way.
Are Advisories Legally Binding?
No. Advisories aren’t legally enforceable the way failures are. If you receive advisory notes, you’re still legally able to drive the car for the full MOT period. But while they’re not binding, they do carry weight. They highlight emerging safety issues, and if an advisory is ignored and an accident results, the situation becomes far more complicated.
So while advisories don’t require immediate repair by law, practically speaking, they still matter.
How to Manage Advisories the Smart Way?
If you want to avoid big repair bills and messy MOT outcomes, treat advisories as a maintenance roadmap. Start by grouping related repairs so you can handle them at a convenient time, rather than facing them all at once later. If a tyre and a brake advisory appear together, handle both during a service. If corrosion has been mentioned, check it again mid-year rather than waiting 12 months.
You can also ask the tester for a priority ranking. Some advisories may need attention in a month or two, while others might be fine for most of the year. Once you know the order of importance, it becomes easier to plan and budget.
A trusted garage makes this process smooth. If you’re in or near Aldershot, GForce Tyres is a strong option for dealing with tyre wear, brake deterioration, exhaust issues, and suspension advisories. Having a reliable workshop that understands MOT-related repairs makes managing advisories simple rather than stressful.
Can an Advisory Become an MOT Failure?
Absolutely, and it happens all the time. A tyre that is close to the legal limit becomes illegal in a few thousand miles. A brake disc showing corrosion might become significantly weakened in twelve months. Early corrosion that isn’t addressed can spread into structural areas.
Advisories are not guesses. They are early versions of next year’s failures.
MOT Advisories and Insurance
Insurance companies usually do not penalise you simply for having advisories. But they expect your car to be in roadworthy condition. If an ignored advisory, such as heavily worn tyres, contributes to a crash, an insurer may question whether the vehicle was properly maintained. Advisories won’t void a policy automatically, but they do play a role in understanding the condition of your car.
Why MOT Advisories Are More Helpful Than You Think?
Advisories save you money, not cost you money. They give you time to plan repairs rather than face sudden expenses. They highlight issues that affect handling, braking, stability, comfort, and safety. They help you avoid breakdowns, and they reduce the chances of failing next year’s test.
Instead of worrying about advisories, use them as early warnings, a guide to what your car will need over the next 12 months.
Final Thoughts
MOT advisory notices are easy to overlook because they don’t stop you from passing, but they’re far more critical than most people realise. They warn you of early-stage problems that will grow, affect safety, impact resale value, and eventually turn into failures. When you treat advisories seriously, checking them, planning repairs, and monitoring your car, the entire ownership experience becomes easier.
And with a local garage like GForce Tyres available to handle MOT-related work, tyre wear, braking issues, suspension deterioration and more, staying ahead of advisories becomes simple.
By understanding what the advisory system really means, you protect your car, your budget and your peace of mind.
