The aim of our group is not to find way to assess or to regulate combinations (as in the PBS approach), but to stick to the UNECE type approval approach addressing individual vehicles.

Which regulations should be modified?

• UN R13: yes
• UN R55: yes
• UN R79: to be further discussed for decision
• No other regulation identified at the moment.

Link between R55 and MVC informal groups

• UN R55 informal group is already dealing with MVC; coordination needed between the two groups.
• Chair proposes MVC group to be an umbrella and could address new points to the R55 IG; the issue is then that the TOR of the R55 group are frozen.
• Is R55 IG covering the complete MVC item in R55? VBG believes some items like the approval of towing trailers are not addressed in the R55 group. VBG agrees to take the task of identifying what is missing in UN R55 IG to fully address MVC in R55.
• Based on this analysis, we could then define how to address the point (in R55 or in MVC group).

Technical issues:

• We need a definition of a dolly to be able to type approve it to UN R13 and R55:
  • What should be the requirements?
  • Where should the definition be? UN R13, RE3 etc.?
  • Should a dolly be type approved to UN R79 (e.g. in case of dolly with front steered axle)?
• Electric control line
• ESC and Stability
• Park brake functionality
• Warning to driver
• Communication between vehicles (ISO11992 and pin 5)
• Requirements for dollies (performance, compatibility etc.)
• CLEPA document GRRF-66-08 is a good base for discussion.

More technical background to be shared at next meeting

• Proposal to get inspiration from other regulations in the field of MVC: ADR in Australia, national regulations in EU, FMVSS etc.
• SWE and FIN agrees to present similar requirements in their own country at next meeting, focussing on technical requirements, rather than on in-use requirements.
li>NW and NL are also invited to check if they can present some information at next meeting.
• BPW proposes to present results at next meeting from a project with Krone on “mega-trailers”

ISO 18868 is proposed as a base for our technical discussions (paragraph 4. ISO vehicle combinations definition”).
