katsastus

Katsastus is the Finnish term for the periodic motor vehicle inspection carried out to verify roadworthiness, safety, and environmental compliance. In Finland, katsastus is mandatory for most motor vehicles and is administered by Traficom, the Finnish Transport and Communications Agency, and conducted by authorized inspection companies.

During the inspection, the vehicle’s essential safety systems and emissions are checked. Inspectors assess brakes, steering, suspension, tires, lights, windscreen and wipers, seat belts, airbags where fitted, exhaust emissions, and the overall condition of safety equipment. The goal is to identify defects that could affect safe operation on public roads. If defects are found, the vehicle fails the inspection and must be repaired before a new inspection can be scheduled; a reinspection is then arranged, usually with a reduced fee.

Information about the vehicle’s inspection status is recorded in Traficom’s digital system, and the owner receives a katsastustodistus (inspection certificate). A valid katsastus is required to drive a vehicle on public roads; driving without a valid inspection can lead to fines, penalties, or the vehicle being taken out of service until it passes.

The interval between inspections depends on vehicle type and age and is defined in Traficom’s regulations. Prices for inspections vary by company and vehicle type. In general, the process aims to minimize safety risks and ensure compliance with emissions standards.
