Approval and application context
The notes below help you assess the scope and conditions. The regulatory text and its exceptions govern your application.
Which level can I use for a new approval?
Use 00 series · Supplement 3 for a new R33 application. The text specifies no different minimum series or staged transition date for new approvals.
- Covers the passenger-compartment structure of M1 vehicles.
- For a vehicle complying with the 01 series of R94, requirements 5.1–5.9 are deemed met; include evidence with the application.
Prepare the evidence for the vehicle’s head-on collision requirements and the approval documents to this level.
What is the latest level, and how long can I use it?
The latest level is 00 series · Supplement 3, effective from 12 June 2025. It imposes no new expiry date on approvals.
- The latest amendment updates vehicle-class and country-code references and the reference for determining the seating position.
- It does not reset the technical limits of the collision test.
Use the current references in a new application.
Must I update my existing approval?
This amendment does not require renewal of every existing approval. Notify changes to the vehicle type to the approving authority.
- The authority assesses the effect on compliance and may require a further test report.
- A test report alone is not vehicle type approval.
Compare the vehicle changes with the approved type and arrange any necessary extension with the approval authority.
