Proposal to allow for the approval of speedometers and odometers that enable drivers to display figures either in km/h or mph (but not both simultaneously). The proposal also clarifies the application of the provisions across the category L vehicle subcategories.

At its fifty-ninth session, GRSP approved a proposal for the 07 series of amendments to UN R16 to mandate safety belt reminders for all vehicle seats. This proposal aligns provisions in UN R121 with the changes to UN R16:
a) the term “seat belt” is replaced by “safety belt”,
b) the symbol for safety belt, defined in item 21 of Table 1 in the Regulation, may be displayed in different colours to convey different meanings. Therefore, the existing footnote ¹⁸ has been added to item 21, and
c) this symbol may be replaced by different symbols for seats other than those of the front row. Therefore, a new footnote ²² is added to item 21. This proposal does not change any of the technical requirements of UN R121.
