Proposal to amend para. 1.4. to clarify that recording requirements depend on availability of the trigger or data element itself, amend para. 5.3.1.2. to permit the EDR to write last stop trigger data in volatile memory only, accommodating at least five most recent stops to be overwritten on a first-in first-out basis until any other trigger occurs or the vehicle master control switch is deactivated, and amend paras. 2.5., 2.48. and 2.49. for clarity and consistency with UN Regulation No. 160.
