One of the most significant changes under consideration would allow drivers to carry out mandatory periodic tests in another EU member state, which is currently not permitted.
If approved, a vehicle registered in Portugal could be inspected in countries such as Spain, France or Germany, with a temporary European inspection certificate issued and recognised for several months.
The proposal is aimed at improving mobility across the bloc, particularly for citizens who live, work or spend extended periods abroad.
Annual inspections
The European Commission had initially proposed compulsory annual inspections for passenger cars more than 10 years old across all EU countries.
However, MEPs rejected the measure, arguing that it was disproportionate and unsupported by clear evidence that it would significantly reduce road accidents.
For Portugal, the decision makes little practical difference, as passenger vehicles are already subject to annual inspections once they reach eight years of age.
The proposed reforms would also expand the technical scope of inspections to reflect advances in vehicle technology.
These additions include checks on advanced safety systems, such as automatic emergency breaking, assessment of airbags and other electronic systems, possible testing for fine particle emissions and nitrogen oxides, and stricter mileage verification to combat odometer fraud.
The measures underline the EU’s growing focus on both road safety and environmental standards.
What would change in Portugal?
Alongside potential European reforms, Portugal has already introduced new inspection rules in 2026, including tighter controls on unresolved vehicle recalls, and cars with outstanding notices could now fail inspection.
The proposals are not yet final and must still go through negotiations between the European Parliament, the European Commission and member states.
