EXPLANATORY MEMORANDUM
I.General
Theprocedure fortheCommunity type approval ofmotor vehicles and
their trailers ,covered bytheCouncil Directive 70/156/EECof6
February 1970 (1),didnotmention hitherto theheating oftheinte­
rior and thewheel guards ofmotor vehicles .However ,since this
Directive wasadopted ,some Member States considered itnecessary
toadopt ,onanational level ,requirements concerning those parts of
vehinles .
Some ofthese national requirements concern more particularly vehi­
cles ofcategory ,i.e. private motor vehicles andother vehicles
used forthetransport ofpassengers andhaving nomore than 9seats ..
For-ythis reason ,theCommission ,inagreement with theexperts ofthe
Member States ,considered itadvisable toinclude ,from thepresent
moment ,inthemodification tothis Directive which will soon be
proposed totheCouncil ,the5tems "heating oftheinterior "and
"wheel guards "forwhich reference will bemade toparticular direct
tives .
This measure will complete theCommunity type approval procedure and
ensure theimplementation ofthis procedure inthenear future ,at
least for this category ofvehicles .
This document relates totheCommission proposals concerning the
above-mentioned directives® These proposals provide for the compul­
sory fitting ofvehicles covered bytheir field ofapplication with
aheating device andwith parts covering their wheels .The annexes of
theproposed directives set out thenecessary requirements foranap­
propriate design ofthese parts ofthe concerned vehicles ,inorder
toensure ,inthe case oftheheating ofthe interior ,thesafety
and comfort ofpassengers and ,inthe case ofwheel guards ,topro­
tect other persons inthetraffic ,against thepossible throwing up
ofstones ,mud ,water ,etc...
