Q3Who is affected

Vehicle manufacturer

For a vehicle without “driver/manual driving controls”, list the provisions related to them. Then find which of them this amendment already covers (para. 0.2.1.).
For vehicles with an ADS other than categories X and Y, do not plan for special provisions or exemptions. This applies in manual or automated driving mode (para. 0.2.2.).

Component supplier

Ask the vehicle manufacturer if the vehicle has “driver/manual driving controls”, because paragraph 0.2.1. depends on this.

Technical service / Approval authority

For a vehicle without “driver/manual driving controls”, leave out the related provisions that this amendment does not already cover (para. 0.2.1.).
For vehicles with an ADS other than categories X and Y, do not apply special provisions or exemptions. This applies in manual or automated driving mode (para. 0.2.2.).
Use Annex 3 to R.E.3, document ECE/TRANS/WP.29/78/Rev. 8, for the distinguishing numbers of the Contracting Parties.
