When preparing your motorcycle for its annual Ministry of Transport (MOT) test, every detail counts. While shiny paintwork and a roaring engine might catch the eye, some of the most crucial components are often overlooked or misunderstood. Among these, motorcycle mirrors hold a surprisingly significant position, not just for passing the test but for your fundamental safety on the road. So, what exactly happens if you decide to remove your mirrors before an MOT? The short answer is unequivocally clear: your motorcycle will fail.

The MOT test isn't just a bureaucratic hurdle; it's a vital safety check designed to ensure your vehicle meets minimum roadworthiness standards. Mirrors are a non-negotiable part of these standards, playing a critical role in a rider's ability to safely navigate traffic and be aware of their surroundings. Removing them, or presenting them in a condition that doesn't meet the regulations, is a direct contravention of the rules and will prevent your bike from receiving a pass certificate.

The Legal Imperative: Mirrors and the MOT
In the United Kingdom, the legal requirements for motorcycle mirrors are quite specific, and the MOT test is designed to verify compliance with these regulations. The primary legislation governing vehicle construction and use dictates that motorcycles must be fitted with mirrors that provide an adequate view to the rear. For most motorcycles manufactured after 1986, this typically means two mirrors are required – one on each side. Older bikes might only require one, but it must still be present and functional.
The MOT examiner isn't just checking for presence; they're scrutinising several key aspects:
- Presence: Are the required number of mirrors fitted?
- Security: Are the mirrors securely attached and do not vibrate excessively or move out of position during normal riding?
- Condition of Reflective Surface: Is the mirror glass clean, clear, and free from significant cracks, discolouration, or damage that would impair the rider's view? Small chips might be acceptable, but anything that obstructs the view will lead to a fail.
- Mounting and Position: Are they mounted in a position that gives the rider an adequate view to the rear and side? They shouldn't be excessively high or low, or obstructed by other parts of the bike or rider.
- No Sharp Edges: Are there any sharp edges or projections that could cause injury in the event of an accident?
Failing on any of these points, let alone the complete absence of mirrors, will result in an immediate fail. It's a fundamental safety item, and its absence or impairment is considered a major defect.
Why Riders Might Consider Removing Mirrors (and Why They Shouldn't)
It might seem counterintuitive to remove such a vital component, but some riders consider it for various reasons, none of which justify the action for an MOT:
- Aesthetics: Some customisation trends favour a 'cleaner' look, leading riders to remove mirrors or replace them with smaller, less conspicuous alternatives that might not meet legal requirements.
- Track Use: For track days, mirrors are often removed to reduce weight, improve aerodynamics, and prevent damage in a fall. However, a bike used on the track must be refitted with legal mirrors for road use and MOT.
- Damage: If a mirror is broken, a rider might remove it rather than replacing it immediately, perhaps underestimating its importance for the MOT.
Regardless of the reason, intentionally removing or neglecting mirrors for an MOT is a guaranteed path to failure and, more importantly, compromises your safety and the safety of others on the road.
The Ramifications of an MOT Failure Due to Mirrors
An MOT failure isn't just an inconvenience; it carries several significant consequences:
Financial Implications
Firstly, there's the cost. You'll have to pay for a re-test, and if you can't fix the issue on the spot (which you can't if mirrors are missing), you'll need to rebook. This means additional time and money spent at the garage. Furthermore, you'll incur the cost of purchasing and fitting new, compliant mirrors.
Legal Ramifications
Riding a motorcycle without a valid MOT certificate is illegal. If caught, you could face:
- A fine of up to £1,000.
- Your insurance becoming invalid, which is a serious offence in itself, potentially leading to points on your licence and further fines.
- Your vehicle being seized by the police.
Even if your MOT is still valid but your mirrors are missing or defective, you could still be stopped by the police and issued with a 'Vehicle Defect Rectification Notice' or a fixed penalty notice for using a vehicle in a dangerous condition.
Safety Risks
This is arguably the most critical consequence. Mirrors provide crucial rearward visibility, allowing you to:
- Check blind spots before changing lanes or overtaking.
- Monitor traffic behind you, especially when slowing down or stopping.
- Identify potential hazards, such as vehicles approaching at speed.
- Make informed decisions about your position on the road.
Riding without mirrors significantly increases your risk of an accident. You become a hazard not only to yourself but to other road users who might assume you have full situational awareness.
Preparing Your Mirrors for the MOT: A Quick Checklist
Before your MOT appointment, a quick check of your mirrors can save you time and hassle. Here's what to look for:
| Aspect | Check Description | MOT Pass/Fail Outcome |
|---|---|---|
| Presence | Are all legally required mirrors (typically two for post-1986 bikes) fitted? | Missing mirrors = FAIL |
| Security | Are mirrors firmly attached? Do they wobble or move easily? | Loose/insecure mirrors = FAIL |
| Reflective Surface | Is the glass clear, clean, and free from cracks or significant damage? | Cracked/obscured view = FAIL |
| Mounting/Position | Do they offer a clear, adequate view to the rear? Are they obstructed? | Poor view/obstruction = FAIL |
| Sharp Edges | Are there any broken parts creating sharp edges? | Sharp edges present = FAIL |
Beyond the MOT: The Indispensable Role of Mirrors in Rider Safety
While the MOT provides a baseline for roadworthiness, the true value of well-maintained mirrors extends far beyond passing a test. They are an essential tool for proactive riding and hazard perception. Many accidents could be avoided if riders had better situational awareness, and mirrors are a primary means to achieve this.
Consider scenarios like filtering through traffic, preparing for an emergency stop, or simply navigating a busy roundabout. Without reliable mirrors, you're essentially riding with half the information you need, relying solely on your peripheral vision and neck checks, which are not always sufficient or safe at speed.

Types of Motorcycle Mirrors and Considerations
There are various types of mirrors available, and while most standard handlebar-mounted mirrors will suffice for the MOT, it's worth understanding the options:
- Standard Handlebar-Mounted Mirrors: These are the most common and typically provide a good field of view, especially when properly adjusted. They are usually the easiest to ensure compliance for the MOT.
- Bar-End Mirrors: Popular for their minimalist aesthetic, these mirrors fit at the ends of the handlebars. They can provide an excellent view, but ensure they are large enough to be compliant and don't protrude excessively, creating a hazard. They must also be securely fitted.
- Fairing-Mounted Mirrors: Found on some sports bikes and touring models, these are integrated into the fairing. Their position can sometimes limit the view, depending on the rider's posture, but they are generally designed to be compliant.
Regardless of the type, the key is proper adjustment. Your mirrors should be set up to minimise blind spots and provide a clear, unobstructed view of the lanes beside and behind you. Take the time to adjust them before every ride, especially if someone else has used your bike or if you've made adjustments to your seating position.
Frequently Asked Questions About Motorcycle Mirrors and MOT
Here are some common questions riders have regarding mirrors and the MOT test:
Q: My bike was manufactured before 1986. Do I still need two mirrors?
A: For motorcycles first used before 1st August 1986, only one mirror is required, and it must be fitted to the offside (right-hand side in the UK). However, having two mirrors is always recommended for safety.
Q: Can I use aftermarket mirrors for my MOT?
A: Yes, as long as they meet the legal requirements for size, security, and provide an adequate view to the rear. They must not have sharp edges or be damaged. The examiner will assess their functionality and compliance, not their origin.
Q: What if my mirror has a small crack? Will it fail?
A: A small chip or crack that does not significantly impair the rider's view might pass, but any damage that obstructs the view or compromises the reflective surface will result in a fail. It's always best to replace a damaged mirror to ensure clarity and safety.
Q: My mirrors vibrate a lot at speed. Is this an MOT failure?
A: Yes, if the vibration is excessive to the point where it significantly impairs the view to the rear, it will be an MOT fail. Mirrors must be securely fitted and provide a reasonably steady image.
Q: Do bar-end mirrors count for the MOT?
A: Yes, bar-end mirrors are acceptable for the MOT, provided they are securely fitted, offer an adequate view to the rear, are of a sufficient size, and do not have any sharp edges. The crucial aspect is the functionality and compliance with visibility requirements, not the mounting location.
Q: Can I tape up a broken mirror for the MOT?
A: No. Taping up a broken mirror is not a repair and will not make it compliant. The reflective surface must be intact and clear. It will still be considered a fail.
Q: What's considered an 'adequate view' for the MOT?
A: An adequate view means that the mirror allows the rider to see clearly behind and to the sides of the motorcycle, covering typical blind spots and providing awareness of following traffic. The examiner will make a subjective judgment based on what a reasonable rider would need for safe operation.
Conclusion
In summary, removing mirrors before your motorcycle MOT is a sure-fire way to guarantee a fail. The MOT test rigorously checks for the presence, security, condition, and functionality of your motorcycle's mirrors because they are paramount for road safety and legal compliance. Don't gamble with your MOT certificate or, more importantly, your safety. Ensure your mirrors are present, properly fitted, and in excellent condition before your test. It’s a simple check that can save you time, money, and potentially, your life on the road.
