draft commission directive amending for the purposes of adapting to technical progress directive 97 24 ec of the european parliament and of the council on certain components and characteristics of two or three-wheel motor vehicles directive 2002 24 ec of the european parliament and of the council relating to the type-approval of two or three-wheel motor vehicles and directive 2009 67 ec of the european parliament and of the council on the installation of lighting and light-signalling devices on two- or three-wheel motor vehicles 37 pages in english . the above-mentioned proposal aims at adapting to technical progress directive 97 24 ec of the european parliament and of the council on certain components and characteristics of two or three-wheel motor vehicles directive 2002 24 ec relating to the type-approval of two or three-wheel motor vehicles and directive 2009 67 ec of the european parliament and of the council on the installation of lighting and light-signalling devices on two- or three-wheel motor vehicles. this adaptation to technical progress includes a revised tailpipe emission test method for categories l1e l2e and l6e mopeds euro 3 level . it also incorporates un regulation no 41 in type-approval legislation with regard to sound level provisions for category l3e motorcycles as well as mandatory fitting of the automatic headlamp-on feature for all l-category vehicles. l-category vehicle is the family name of light vehicles such as powered cycles mopeds motorcycles tricycles and quadricycles. the proposed euro 3 ste carries over the euro 2 emission limits set out in chapter 5 of directive 97 24 ec currently in force but modifies the emission laboratory test cycle in order to take into account emissions after cold-start. in addition the proposal foresees the measurement and reporting of co2 emissions as well as a mandatory statement from the manufacturer to ensure that zero emissions will be expelled from the crankcase ventilation system over the useful vehicle life. in order to improve the visibility of vulnerable road users in traffic and thus improve the functional safety of l-category vehicles it is proposed to require that the headlam is automatically turned-on aho when the ignition is switched on or alternatively installing day time running lights therefore significantly improving vehicle and rider conspicuity in comparison to other traffic participants. this measure also levels the playing field among the l-category vehicle manufacturers active on the eu market. in addition the proposal contains a reference to unece regulation no 41 with regard to sound requirements for l3e motorcycles. recognising the equivalence of these unece requirements as an alternative to the provisions on the sound level set out in chapter 9 of directive 97 24 ec enables manufacturers to benefit from mutual recognition under the umbrella of the unece thus reducing burden by avoiding repeated testing and issuing redundant paperwork.
