As your car's annual MOT test approaches, many drivers find themselves pondering a simple yet surprisingly common question: what exactly should I leave inside my vehicle when I drop it off at the test centre? The short, unequivocal answer often surprises people: ideally, nothing at all. While this might sound extreme, there's sound reasoning behind it, rooted in the safety, efficiency, and thoroughness of the MOT inspection process. Preparing your car correctly isn't just about ensuring it passes; it’s about facilitating a smooth, safe, and professional examination.

Think of the MOT as a detailed health check for your vehicle, designed to ensure it meets minimum road safety and environmental standards. For the authorised examiner to conduct this comprehensive inspection effectively, they need unhindered accessibility to various parts of your car, both inside and out. Any obstruction, no matter how small, can impede their work and potentially lead to delays or even a refusal to test, costing you time and money. Let's delve deeper into what this 'empty car' principle truly means and how you can best prepare your vehicle for its vital annual assessment.
The Golden Rule: Less is More
The primary reason for advising an empty car is straightforward: the examiner needs clear, unobstructed access to every part of the vehicle that requires inspection. This includes footwells, under seats, the boot, and around the dashboard controls. Loose items can be a safety hazard, falling or shifting during the test, especially when the vehicle is moved or lifted. Furthermore, personal belongings simply get in the way, making the examiner's job more difficult and time-consuming. Imagine trying to check seatbelt anchorage points, the floor pan for corrosion, or the functionality of controls if they are obscured by bags, coats, or even children's toys.
An uncluttered vehicle allows the examiner to perform their duties efficiently and accurately, reducing the chances of anything being missed or, conversely, of unnecessary delays because items need to be moved. It demonstrates that you, as the owner, take the test seriously and respect the examiner's time and the stringent requirements of the MOT.
Understanding 'None': What Should Definitely Go
Personal Belongings and Clutter
This category encompasses almost anything that isn't a permanent fixture of your car. This includes, but is not limited to:
- Bags and Luggage: Handbags, briefcases, shopping bags, gym bags – remove them all from the cabin and boot.
- Coats and Clothing: Jackets, jumpers, hats, and scarves often left on seats or in footwells should be taken out.
- Food and Drink: Empty any food wrappers, drink bottles, and ensure no perishable items are left behind.
- Books, CDs, DVDs, and Paperwork: Clutter in door pockets, glove compartments (unless it's essential vehicle documentation), or on seats should be cleared.
- Sports Equipment: Golf clubs, gym gear, cycling shoes, or any other bulky items in the boot or on the back seats.
These items can obstruct access to seatbelts, their anchorage points, the floor, and under-seat areas which need to be checked for corrosion or damage. They also pose a trip hazard or can fall during vehicle movement within the test centre.
Child Seats and Booster Seats
This is a particularly important point. While child seats are crucial for safety during everyday driving, they should always be removed for an MOT. The examiner needs clear access to all seatbelts and their anchorage points, as well as the seats themselves and the floor beneath them, to check for damage, wear, or corrosion. Trying to inspect a seatbelt buckle or the condition of the seat fabric with a bulky child seat strapped in is impractical and could lead to a 'fail' simply because the component couldn't be properly assessed. Remember, it's your responsibility to correctly refit any child seats after the test.
Excessive Tools and Unsecured Items
While a basic toolkit or a small emergency kit might be acceptable if securely stowed, a boot full of loose tools, spare parts, or other heavy, unsecured items is not ideal. These items can shift during the test, potentially causing damage to the vehicle's interior or, more critically, posing a risk to the examiner. If you have a legitimate need to carry tools, ensure they are neatly organised and secured in a toolbox or dedicated storage compartment.
Rubbish and Debris
Before your MOT, take a few minutes to give your car a good clear-out. Empty rubbish bins, remove any stray food wrappers, and perhaps even give the interior a quick vacuum. A clean, tidy car not only makes a better impression but also allows the examiner to easily spot any potential issues, such as obscured warning lights, damaged interior components, or areas of corrosion that might otherwise be hidden by dirt or debris.
What CAN Stay (and Why It's Different)
While the 'empty car' rule is paramount, there are a few items that are either integral to the vehicle's operation, legally required, or commonly carried and can remain, provided they are securely stowed and don't impede the test.
Essential Vehicle Equipment
- Securely Fitted Spare Wheel and Tyre: If your vehicle has a spare wheel, it should remain in its designated, secured location (e.g., under the boot floor or on an external carrier). The condition of the spare tyre isn't usually part of the MOT test itself, but its secure mounting is.
- Locking Wheel Nut: This is absolutely critical! If your vehicle has alloy wheels secured with locking wheel nuts, you must ensure the key for these nuts is easily accessible to the examiner. Without it, they cannot remove the wheels to check the brakes, wheel bearings, or suspension components, which will result in an immediate refusal to test or a failure. Place it in a visible spot, such as the glove compartment or on the passenger seat.
- Vehicle Handbook/Service Book: While not strictly required for the test, having your vehicle's handbook or service history readily available can be useful for the examiner, particularly if they need to verify mileage or specific vehicle details. Keep it in the glove compartment or a designated holder.
- Warning Triangle/First-Aid Kit: These items are not mandatory for vehicles in the UK, but if you carry them, ensure they are securely stowed in the boot and do not obstruct any areas the examiner needs to access. Their presence doesn't affect the MOT outcome.
Fitted Accessories
- Dash Cams: A securely mounted dash camera that does not obstruct the driver's view of the road (as per windscreen zone regulations) or impede the examiner's access to controls can remain. If it's loose or dangling, remove it.
- Fixed Phone Holders/Sat-Navs: If permanently or securely affixed to the dashboard or windscreen (again, not obstructing the driver's view), these can stay. Any temporary, unsecured devices should be removed.
Beyond Emptying: Preparing for a Smooth MOT
While clearing out your car is a significant step, a comprehensive preparation goes further. A few simple checks before you drop off your vehicle can dramatically increase its chances of passing first time:
- Check All Lights: Headlights (main and dipped beam), sidelights, brake lights, indicators, fog lights, reverse lights, and number plate lights. Ensure they all work and are the correct colour.
- Tyres: Check the tyre pressure, tread depth (minimum 1.6mm across the central three-quarters of the tread, around the entire circumference), and for any damage, bulges, or cuts.
- Wipers and Washer Fluid: Ensure your windscreen wipers clear the screen effectively without smearing and that your washer fluid reservoir is topped up. The jets must work correctly.
- Fluid Levels: Check oil, coolant, brake fluid, and power steering fluid levels. While not directly part of the MOT, low levels can indicate underlying issues.
- Horn: Give it a quick blast to ensure it works.
- Mirrors: Ensure all mirrors (interior and exterior) are intact and securely fitted.
- Number Plates: Make sure they are clean, legible, and correctly fitted.
Cleanliness Matters
A clean car, both inside and out, can make a difference. Not only does it leave a good impression on the examiner, but it also allows them to more easily spot potential issues. A dirty undercarriage can obscure corrosion or damage to brake lines and suspension components. A clean interior means no hiding spots for defects. This proactive approach shows the examiner that you maintain your vehicle well and care about its condition.

The Examiner's Perspective: Making Their Job Easier
From the examiner's point of view, a well-prepared, empty car allows them to focus solely on the technical aspects of the test. They don't have to waste time moving your belongings, nor do they run the risk of damaging them. This efficiency contributes to a quicker turnaround time for your vehicle and ensures that the inspection is as comprehensive and accurate as possible. Remember, the MOT is a strict, standardised test, and anything that helps the examiner adhere to these standards without distraction is beneficial for all parties involved.

Frequently Asked Questions (FAQs)
Do I really need to take *everything* out?
Ideally, yes. While a single pen in the glove box won't cause an issue, the principle is to remove anything that could obstruct the examiner's access to components, pose a safety risk, or simply get in the way. The less there is, the smoother the process.
What if I forget something in the car?
For minor items, the examiner might simply move them aside. However, if there's significant clutter, child seats, or heavy loose items, the test centre may ask you to remove them before the test can proceed. In extreme cases, they might even refuse to test the vehicle until it's cleared, leading to delays and potential re-booking fees.
Should the car be clean?
Absolutely. While not a direct 'fail' item, a clean car (inside and out, especially the undercarriage) significantly aids the examiner. Dirt and debris can obscure defects or make it difficult to properly inspect components like brake lines, suspension, and the vehicle's structure for corrosion.
What about the spare tyre and jack?
If your car is fitted with a spare wheel, it should remain in its designated, secured location. The spare tyre itself isn't directly tested, but its secure mounting is. Ensure your jack and wheel brace are also securely stowed. Most importantly, ensure the locking wheel nut key is readily available if your wheels require one.
Do I need to remove my dash cam?
Only if it's unsecured, dangling, or obstructs your view of the road from the driver's seat as per the MOT visibility guidelines. If it's neatly and securely mounted and doesn't interfere with the examiner's access to controls or their view, it can usually stay.
What about my service book?
While not a mandatory item for the MOT, it's a good idea to leave your service book or any documentation relating to your car's mileage in a visible spot, such as the glove compartment. The examiner will record the mileage, and having the service history can be useful for verification.
Ultimately, the goal of the MOT is to ensure your vehicle is safe and roadworthy. By taking the time to clear out your car and perform a few basic checks beforehand, you're not only making the examiner's job easier but also giving your vehicle the best possible chance of passing its MOT first time. A little preparation goes a long way in ensuring a smooth and successful test, keeping you legally on the road until your next annual inspection.
