Approval and application context

The notes below help you assess the scope and conditions. The regulatory text and its exceptions govern your application.

I am applying for approval for the first time. Which level can I use, and what is the deadline?

You can apply for an M1 passenger car to 00 series · Supplement 2. The text sets no transition date closing applications under preceding levels.

  • R42 covers the behaviour of front and rear protective structures in low-speed collisions.
  • Provide the vehicle structure, protective devices, dimensions and unladen weight in the application.

Prepare a representative vehicle for testing and confirm that R42 approval can be used in your destination country.

What is the latest level, and until when can I use it?

The latest level is 00 series · Supplement 2, effective from 3 January 2021. The text gives it no expiry date.

  • Braking, steering and other basic vehicle systems must work normally after low-speed impacts.
  • A driver assistance sensor or camera may be damaged, provided basic braking and steering performance remain intact.

Apply the distinction in paragraph 6.1.5 when checking front and rear impacts.

Must I update my existing approval or test report? To which level, and by when?

Supplement 2 sets no common deadline to renew all existing approvals. Notify the granting authority of changes to the vehicle type.

  • The authority may accept that the change has no adverse effect or require another test report.
  • Basic braking and steering performance must still remain intact after impact.

Report structural or protective-device changes with the approval number; agree any extension and testing needed.
