Most people think about the roadworthiness test only once the deadline has already passed. If you drive a Slovak-registered car or plan to buy a used one in Slovakia or Czechia, it pays to know the local rules: the deadlines, the cost, and the reasons why almost one in eight Slovak vehicles failed at the first attempt in 2024.
The deadlines in Slovakia
For M1 passenger cars, Slovakia applies a simple 4 – 2 – 2 rule: the first technical inspection (STK) no later than four years after first registration, then every two years. The emissions test (EK) follows the same schedule for diesel engines and for petrol engines with a catalytic converter and lambda sensor.
Older petrol cars without a regulated catalytic converter are the exception: emissions testing after one year, then annually. Shorter intervals also apply to taxis and driving-school vehicles. Neighbouring Czechia works almost identically – first inspection after four years, then every two years.
Watch the sticker on the licence plate: it shows only the month and year. The exact last day of validity is in the inspection report. You can also check validity free of charge online with the authorised technical service (testek.sk).
What it costs
Prices in Slovakia are not regulated – every station sets its own. As a guide, expect around 40 € for the technical inspection and roughly 35 € for the emissions test, so usually 65 to 95 € in total depending on the region and the station. For LPG cars the emissions test is a little more expensive, around 45 €.
If the car fails, a re-test at the same station within 60 days is considerably cheaper, because only the recorded defects are checked. That is exactly why it makes sense to go early rather than in the final week before the deadline.
Why cars fail
In 2024 roughly 1.58 million technical inspections were carried out in Slovakia and 88.33 % of vehicles were found roadworthy. The list of the most common reasons for failure barely changes from year to year:
- Brakes – uneven service-brake action, fluctuating braking force, a weak parking brake, worn discs. The number one cause for years.
- Lighting – a dead brake light or indicator, badly aimed headlights, a burnt-out number plate light.
- Corrosion of load-bearing parts – sills, wheel arches and axle mountings on cars with many winters behind them.
- Tyres – insufficient tread depth, different types on one axle, or a size that does not match the documents.
- Fluid leaks – brake fluid and engine oil above all.
What to check the day before
Most of the small stuff shows up in a car park. Ask someone to help and check every light, including reverse, fog lights and the plate light. Top up the washer fluid, replace wiper blades that smear, inflate the tyres to the specified pressure and measure the tread.
Bring the registration certificate, proof of third-party liability insurance and the mandatory equipment. An illuminated airbag, ABS or engine warning light usually counts as a serious defect, so deal with it beforehand. And if you mostly drive short urban trips, take a longer run before the emissions test so the engine and catalytic converter reach working temperature.
What happens if you miss the deadline
A driver caught in Slovakia without a valid inspection faces an on-the-spot fine of up to 50 €, or up to 100 € in administrative proceedings. The penalty aimed at the vehicle keeper is considerably harsher: the district authority imposes 165 € for failing to present the vehicle for technical inspection and the same again for the emissions test – up to 330 € in total, per vehicle.
Add to that the risk in the event of a claim. An expired inspection alone does not void your cover, but if the insurer shows that poor technical condition contributed to the damage, it can reduce the payout or demand it back.
Why it matters when buying and selling
A vehicle needs a valid technical inspection and emissions test to be transferred to a new owner, so the inspection date directly affects how quickly a deal can close. If you are selling, a fresh inspection is one of the cheapest ways to make a listing credible: put the expiry date in the text and add a photo of the report.
If you are buying, always ask for the report. Besides the list of defects it records the odometer reading at the time of the inspection, so older reports are a simple way to sanity-check mileage. A car whose inspection expires in a few weeks is not a bad buy, but it should be reflected in the price.
When it is your turn to sell, listing on AutoCasa is free, with no sales commission and no limit on the number of ads – from cars and motorcycles through vans, trucks and buses to trailers, spare parts, wheels and tyres or bicycles. Promoting a listing is optional and starts at 1.50 €.
This article describes the rules in force in Slovakia – Act No. 106/2018 Coll. on the operation of vehicles and Act No. 8/2009 Coll. on road traffic, as in force in September 2026. Other countries have their own rules. Inspection prices are not regulated and differ between stations.
