Vehicle registration, plates & vignette

Beyond the technical side, a vehicle must be in order administratively. These points come up regularly in the test because they are easy to check at the roadside.

The vehicle registration document

The vehicle registration document must be carried on every journey and produced to the police on request.

It records the vehicle data: keeper, permitted weights, number of seats, towable load and approved equipment. Significant changes – a move, a change of keeper, technical modifications – must be reported to the road traffic office.

Number plates

  • White: ordinary cars and motorcycles.
  • Yellow: mopeds.
  • Green: agricultural and forestry vehicles.
  • Blue: works vehicles.
  • Brown: special vehicles with a permit.

Plates are allocated to the keeper, remain state property and must be returned when the vehicle is taken off the road. They must be legible and clean – a plate covered in snow or mud is an offence.

Exhaust emissions check

Motor vehicles must be in order as regards emissions. Modern ones are monitored by on-board diagnostics; older ones require a periodic check.

An emissions warning light is not just an environmental problem: it usually points to a fault that increases consumption and wear.

The motorway vignette

On motorways and semi-motorways (signed in green) the vignette is compulsory – for motorcycles and trailers too.

  • It costs 40 francs.
  • It is valid from the preceding 1 December to the following 31 January.
  • A trailer needs its own vignette.
  • The adhesive vignette must be stuck directly to the windscreen; tucked behind the glass it is not valid. An electronic vignette linked to the plate also exists.
