On a Swiss listing, one word shows up everywhere: "expertisé". On its own, it says very little. What matters is the date next to it, and what the inspection actually examined that day. It is one of the first reflexes covered in the 8 things to check before buying, and it is also the biggest source of misunderstanding between a seller and a buyer. For the registered keeper, the expertise often feels like an opaque formality: a summons arrives, you are not sure what to prepare, and you find out the result on the spot. This article walks through how the inspection runs, what gets examined, the failure reasons we keep seeing, and how to present a vehicle that stands a chance of passing first time.
What an expertise actually is
The expertise is the official conformity and safety inspection of a vehicle. It is carried out by the road traffic office of your canton of residence, or by an authorised body depending on how the canton is organised. It is not a garage service, and it is not the same thing as a private inspection commissioned by a buyer or an insurer: those exist, but they carry no authority.
It comes up in several situations: the periodic inspection ordered by the canton, a first registration, a vehicle arriving from another canton, an imported vehicle, or a vehicle modified from its original state. For the periodic inspection, it is the canton that summons you, at its own pace and under its own rules. The keeper does not freely pick a date: you receive a slot. We give no figures on frequency here, since that depends on the canton and the vehicle category. Check with your cantonal road traffic office.
The summons, the appointment and what to bring
The summons arrives by post, with a date and a place. If the slot does not suit you, rescheduling is usually possible, but under rules and deadlines specific to each canton. Do not let the date pass without reacting.
On the day, bring the vehicle registration document, valid proof of insurance and, if you have it, the last inspection report. Two practical points save time on site:
- A vehicle that is clean on top and underneath. An underbody caked in mud or salt makes corrosion and fixings harder to read, and nobody benefits from an inspector having to guess.
- An empty boot. The spare wheel, the jack and the tool kit need to be reachable without moving your belongings around.
Forms, deadlines and procedures vary from one canton to the next. For any administrative question, the contact is the cantonal road traffic office, not a garage.
What gets checked, item by item
The inspection follows families of checkpoints. Here is what gets looked at, without going into limit values, which are not ours to set:
- Braking: efficiency, balance between wheels, visible condition of discs, pads, hoses and the parking brake.
- Steering and running gear: play in the column, ball joints, track rods, bushings, driveshaft boots.
- Suspension: dampers, springs, general behaviour of the axle.
- Lighting: operation of every lamp, beam alignment, light sources matching the headlight type.
- Tyres and wheels: wear, consistency across the car, sidewall condition, sizes and rims matching the registration document.
- Exhaust and emissions: sealing, mountings, measured values according to the engine type.
- Structure and corrosion: chassis rails, anchor points, floors, load-bearing elements.
- Interior: seat mountings, belts and retractors, controls.
- Glazing and visibility: windscreen condition, wipers, washers, mirrors, any window film.
- Conformity: the vehicle presented matching what appears on the registration document.
What gets a vehicle turned down
We have no official statistics to put forward. What follows is a workshop observation, based on the vehicles we prepare or take in:
- Tyres at the limit, mismatched, or fitted in a size that does not match the registration document.
- Misaligned lighting, a non-compliant bulb, a lamp that no longer works.
- Play in the steering or in the ball joints.
- Discs and pads at the end of their life, or a leak of oil, brake fluid or steering fluid.
- Perforating corrosion on a load-bearing element, always the most expensive subject.
- An engine warning light on, even if the car drives normally.
- Wheels, suspension or exhaust modified without type approval.
- A windscreen cracked in the driver's field of vision.
Minor defect, blocking defect, re-inspection
Not everything carries the same weight. A report may note a simple remark, with no immediate consequence. It may flag a defect to correct, with an obligation to provide proof of repair or to bring the vehicle back. And it may record a serious defect, which prevents the vehicle from going back on the road.
The re-inspection means returning once the work is done. Its deadlines, organisation and fees are a cantonal matter: we quote neither a duration nor an amount here, and you will avoid unpleasant surprises by asking for that information directly on the report or from the office. Same thing for the question "can I keep driving in the meantime": that depends on the severity recorded and on the authority's decision, not on a general rule.
Preparing your vehicle before the appointment
The day before, a fifteen minute inspection removes a good share of the avoidable failure reasons. Walk around the lights, headlamps, indicators, brake lights and illuminated plate, with someone standing outside. Look at the tyres, including the sidewalls and the spare. Check the fluid levels, the wipers and the washers. Make sure no warning light stays on in the instrument cluster. Confirm that the registration document data still matches the vehicle as it is today.
The rest justifies a workshop visit before the appointment. A pre-inspection measures what cannot be seen from the pavement: brake balance, play, geometry, condition of the bushings. It costs less than a re-inspection combined with a vehicle off the road. That is also why the maintenance habits that avoid unpleasant surprises matter as much as they do, and why sticking to the manufacturer intervals works out cheaper over time than catching up in the week of the inspection.
Imported or modified vehicles
Two situations call for more preparation.
A vehicle brought in from abroad has to have its conformity established before it can run on Swiss plates. That is a full file, with documents to gather and sometimes technical adaptations. The subject is covered in detail in type approval for an imported vehicle, which also deals with customs clearance. If importing is your way into the market, read the guide to buying a used car in Switzerland as well before committing.
Then the modified vehicle. Wheels, suspension, exhaust, tinted windows: every modification has to be justifiable. And a change of appearance is not limited to mechanical parts. If a wrap changes the colour of the vehicle, that colour no longer matches the registration document, and the change has to be declared to the canton. The procedure is described in our article on declaring a colour change after a wrap.
Why a recent expertise changes the sale price
A vehicle inspected days ago removes the buyer's main reason to hold money back. Facing a car whose last report is old, the buyer reasons for the worst: they mentally deduct the cost of repairs they cannot put a figure on. Facing a fresh report, that argument is gone, and the negotiation is about the vehicle rather than about an imagined risk. In practice, the price gap often exceeds the cost of the operation, and the car sells faster.
This is exactly the Swiss factor that foreign valuation calculators ignore, as we explain in what really sets the price of a used car. Presentation adds to it: an expertise certifies conformity at a given moment, it does not guarantee the absence of future breakdowns, and it does not replace the care given to the vehicle. Bringing the cosmetics back up to standard before showing the car works on the same mechanism, by removing pretexts for negotiation.
One useful point: we prepare and present vehicles, we do not issue the official report. Our role is preparation and support, the authority's role is the inspection. If you are thinking of selling once it has passed, placing your vehicle on consignment is the option that leaves the sales work to the garage. In any case, the simplest move is to talk to us about your vehicle before the appointment rather than after.
