Suggestions Several countries and regions have issued and implemented EDR /standards. UN R160 has already made tremendous progress. Proposals for Supplement 1 to 00 series and 01 series of UN R160 had been adopted. The STEP 1 of the process of EDR Guidance for 1958 and 1998 is finished and IWG has moved on to the STEP 2. Several countries and regions have accumulated rich experiences in implementing its own EDR regulations/standards. These experiences are very informative to the STEP 2 work of EDR IWG. In order to accelerate the process of EDR IWG (STEP 2), we suggest listing the existing national EDR regulations/standards into the compendium of candidates. 4
