On August 22, 2026, the Republic of Türkiye Ministry of Industry and Technology published an amendment to the Regulation on Type Approval and Market Surveillance of Motor Vehicles and Their Trailers (AB/2018/858), effective the same day.

The amendment replaces Article 86(3) and clarifies end-of-series treatment for vehicles that were covered by a valid EU or national type approval when manufactured but were not registered or put into service before that approval lost validity because of mandatory new legislation.

The Certificate of Conformity (CoC) date is the reference point. Complete vehicles with a CoC dated before the relevant mandatory application date may be sold and registered within 12 months from that date. Incomplete vehicles may be sold within 18 months, completed under the provisions valid on the base vehicle type-approval date, and registered within that period.

For Category O trailers, the amendment adds 12 months for complete vehicles and 18 months for incomplete vehicles to dates specified in the relevant legislation. Separate M/N registration conditions in sector legislation remain controlling where stated.

Impact assessment:

Medium. The amendment is final and immediately effective, but it mainly clarifies and extends end-of-series sale/registration windows rather than introducing a new testing burden.

Key reasons:

• The revised Article 86(3) changes the timing rules linked to loss of type-approval validity
• Makes the CoC date central
• Establishes specific extensions for Category O trailers.

Who is affected?

Vehicle manufacturers, importers, distributors, type-approval holders, dealers, registration stakeholders, manufacturers of complete or incomplete Category O trailers.

Conclusion:

Companies managing end-of-series stock should update registration and inventory planning to apply the 12- and 18-month windows from the relevant mandatory application date.
