The Institute of Mobility and Transport (IMT) identifies tyres, lighting, rear-view mirrors, seatbelts and windscreen wipers as elements checked during mandatory periodic inspections. Before going to an inspection centre, the driver can check at home whether tyres have at least 1.6 millimetres of tread depth and show no cuts or deformities. They should also confirm that all lights are working, including dipped beams, full beams, brake lights, reverse lights and number plate lighting, as well as ensuring that mirrors are properly attached and seatbelts function correctly.
Legislation classifies deficiencies into three types: type 1 does not seriously affect safety, type 2 seriously affects operation or safety, and type 3 corresponds to very serious situations. However, a vehicle fails if it has not corrected previously noted deficiencies, if it presents more than five type 1 deficiencies, or at least one type 2 or 3 deficiency. Therefore, it is advisable to consult the previous inspection report and confirm that problems have been resolved.
Since March 2026, there is a new check that can cause failure: pending recalls. When a vehicle presents itself for inspection with an active recall action that has not yet been corrected, this information appears on the report and the vehicle fails. The check can be done free of charge through the RECALL platform; simply enter the registration number or VIN. If there is a pending recall, the owner should contact a brand representative for the free repair.
It is also important to look for signs of brake problems, such as abnormal vibrations, noises or pulling to one side during braking, as well as checking the windscreen for cracks that interfere with visibility. The driver should also look at the ground where the vehicle was parked to detect possible oil or coolant leaks. For the inspection, the Vehicle Registration Document and the previous inspection report are required, except for the first time.
