Status report on two workshops on Door Opening Warning Systems held virtually on 1 April 2026 and 2 September 2026. The first workshop presented accident data from Germany and China and conducted exploratory discussions on system parameters. The second workshop presented accident data from Germany, China, Belgium, the United Kingdom and France, and introduced draft regulatory text covering scope, definitions, signalling strategy, operational parameters, activation and deactivation, failure detection and test procedure. Comments were received from industry, cyclists’ organisations and Contracting Parties. The experts from China and Germany propose establishment of an informal working group on DOWS to develop proposals concerning justification and problem definition, scope and definitions, performance requirements, test and assessment procedures, and regulatory form.

Proposal to establish uniform provisions for type approval of vehicles of categories M₁ and N₁ equipped with a Door Opening Warning System (DOWS) intended to reduce the risk of collisions involving opening vehicle doors and approaching vulnerable road users. The system shall provide information signals indicating the presence of a dooring-related vulnerable road user in the detection area and door opening warning signals to alert occupants when a door opening attempt is initiated and collision risk is imminent. The Regulation specifies technical requirements including system availability, signalling requirements, failure indication, and test procedures for verification at type approval.

Proposal to amend para. 5.3.3.2. to correct a referencing error by replacing the reference to para. 5.1.4. with a reference to para. 5.3.1.1., which directly relates to mechanical parts of the steering transmission, thereby removing possible uncertainty or the need to liaise with the designated technical service or approval authority to confirm interpretation of the current text.

Proposal to:

• insert new paragraphs 2.71. to 2.78. defining
  • Position Code,
  • Turn Signal Switch Status,
  • Hazard Warning Signal Switch Status,
  • Hazard Warning Signal Lamp Status,
  • Turn Signal Lamp Status,
  • Gear Positions,
  • Seat-Track Position-1, and
  • Seat-Track Position-2,
• Delete existing data elements for Safety belt status by driver position, Frontal air bag deployment by driver and front passenger, Side air bag deployment by driver and front passenger, and Pretensioner deployment by driver and front passenger,
• Amend Table 1 to replace position-specific safety belt, frontal air bag, side air bag, knee airbag, far-side airbag, pretensioner, and occupant size classification entries with X-Y Position Code entries,
• Add Turn Signal Lamp status, Hazard Warning Signal Lamp Status, Turn Signal Switch Status, Hazard Warning Signal Switch Status, Gear Positions, and Seat-Track Position entries with recording intervals from -5.0 to 0 seconds or -1.0 seconds and sample rates of 2 samples per second.
