The French controle technique keeps evolving, and 2026 brings several notable changes. Stricter emission standards, new ADAS checks, and expanded OBD diagnostics mean you’ll want to know what to expect before booking your appointment. Here’s the full breakdown.
The Basics
How Often
The first controle technique is due within 6 months before the vehicle’s fourth birthday (from first registration). After that, it’s every 2 years.
For a sale, the CT must be less than 6 months old. If a re-inspection (contre-visite) was required, it must be completed within 2 months of the initial check.
Which Vehicles
All passenger cars and light commercial vehicles (up to 3.5 tonnes GVWR) need a controle technique. Motorcycles and powered two-wheelers have had their own schedule since 2024.
What Gets Checked
The CT covers 133 checkpoints across 9 categories:
- Vehicle identification: VIN, registration plate, fuel type
- Braking: discs, pads, lines, parking brake
- Steering: play in the steering, ball joints, rack
- Visibility: windscreen, mirrors, wipers
- Lighting: headlights, tail lights, indicators
- Road contact: tyres, suspension, bearings
- Structure and bodywork: corrosion, deformation, fixings
- Equipment: seatbelts, airbags, horn
- Emissions and noise: exhaust emissions, catalytic converter, silencer
Each point gets one of three ratings: minor deficiency (noted but no re-inspection), major deficiency (re-inspection within 2 months), or critical deficiency (immediate driving ban except to return home).
What’s New in 2026
Stricter Emission Controls
Emission thresholds have been tightened for both petrol and diesel vehicles. For diesels, the smoke opacity test now uses a stricter limit of 0.7 m-1 instead of the previous 1.5 m-1 for newer vehicles fitted with a DPF. Petrol cars are tested on CO, CO2, and hydrocarbon values at idle and elevated RPM.
In practice, a failing catalytic converter or a damaged diesel particulate filter will almost certainly trigger a re-inspection. If your engine warning light is on, the car will fail.
ADAS Checks (Driver Assistance Systems)
Driver assistance systems are now subject to a visual inspection. The inspector checks that cameras and visible sensors appear functional, that warning stickers are present, and that no ADAS-related warning lights are illuminated on the dashboard. This remains a visual check only: there’s no electronic diagnostic of ADAS systems for now.
Enhanced OBD Verification
OBD port diagnostics are becoming standard practice. The inspector plugs in a diagnostic tool to check for active engine fault codes and verify that pollution readings match ECU data. This targets vehicles where the emission control system has been removed or modified (DPF deletes, non-homologated ECU remaps).
How Much Does It Cost in 2026
Controle technique prices aren’t regulated. Each centre sets its own rates. Here are the ranges seen in 2026:
| Service | Average price | Range |
|---|---|---|
| Periodic controle technique | 82 euros | 60 to 120 euros |
| Re-inspection (contre-visite) | 18 euros | 10 to 35 euros |
| Additional pollution check | 35 euros | 25 to 50 euros |
| Voluntary check (not mandatory) | 82 euros | 60 to 120 euros |
Prices vary significantly by region. Ile-de-France and major cities are generally more expensive. Rural areas tend to be cheaper. Comparing nearby centres can save you 20 to 40 euros.
How to Prepare Your Vehicle
Two Weeks Before
Walk around the car and check the obvious points:
- Lighting: verify every bulb works (headlights, tail lights, indicators, reverse light, number plate light). A single blown bulb almost guarantees a re-inspection.
- Tyres: tread depth must exceed 1.6mm (the wear indicator shouldn’t be level with the tread). All 4 tyres must match in size and load rating. No bulges or visible cuts.
- Windscreen: a chip in the driver’s line of sight triggers a re-inspection. Cracks over 30cm do too.
- Wipers: worn blades that leave streaks will cause a fail.
The Day Before
- Check fluid levels: engine oil, coolant, brake fluid, washer fluid.
- Clear the engine warning light if it’s on. If it comes back after clearing codes, get the issue diagnosed before the CT.
- Make sure the parking brake works properly.
- Clean the mirrors and windscreen.
The Most Common Reasons for Re-inspection
According to UTAC OTC statistics, the most frequent deficiencies are:
- Lighting faults (headlight alignment, blown bulbs): 25% of re-inspections
- Braking (worn discs, end-of-life pads): 18%
- Excessive emissions: 15%
- Tyres (wear, non-conforming sizes): 12%
- Road contact (shock absorbers, ball joints): 10%
Most of these are fixable at moderate cost. Replacing a headlight bulb costs 5 to 30 euros. A set of front brake pads runs 50 to 150 euros including labour.
What to Do After a Re-inspection
You’ve got 2 months to make the repairs and present the vehicle for re-inspection. The contre-visite only covers the items that caused the fail, not the entire vehicle.
You don’t have to return to the same centre. Any approved centre can do the re-inspection. Shop around: some centres offer free re-inspections if the initial check was done with them.
If you miss the 2-month deadline, you’ll need a full new controle technique.
The CT When Selling
If you’re selling your vehicle, the CT must be less than 6 months old when the certificat de cession is signed. The CT report is one of the mandatory documents given to the buyer, along with the crossed-out carte grise and the certificat de cession.
The buyer has every right to refuse a vehicle whose CT shows uncorrected major deficiencies. In practice, it’s better to fix issues before selling: a clean CT reassures the buyer and makes negotiation easier.
A full diagnostic of your vehicle before the controle technique lets you anticipate problems. Automano can help you visually identify bodywork defects and assess the car’s general condition before heading to the inspection centre.
