EXPLANATORY MEMORANDUM
Ii»General
1.TheChapter onthe field ofvisxon al§o forms part oftheproce­
dure for the Community type approval ofmotor vehicles and of
1)their .trailers covered bytheCouncil Directive of6February 1970
2)2.On5August 1968 theCommission addressed totheCouncil apro­
posal on,inter alia ,the field ofvision .TheCouncil felt that
itwasinappropriate toexamine these requirements before the adop­
tion oftheDirective ontype approval since this Directive insti­
tuted the administrative procedure for thevarious directives ofa
technical nature .Inthemeantime ,other international organiza­
tions have begun work onharmonization inthis field .The field
ofvision isone ofthe characteristics which influence the overall
..design ,ofavehicle .Itistherefore desirable that theharmoniza­
tion ofthetechnical .requirements shpuld extend in ,scope beyond
the frontiers oftheEuropean Communities ,sothat Community motor
manufacturers are not -obliged tosubstantially modify vehicles in­
tended for sale innon-member countries .'•The Commission therefore
rfelt that itwas justified -that the -Council should notbegin 'to
examine itsproposal until theinternational work onthesubject
hadreached acertain stage offruition .After difficult and
laborious discussions ,tangible results have now been achieved in
the form ofadraft regulation relating tothe field ofvision
which could satisfy theconstruction requirements forboth "Euro­
pean "and "American "types ofvehicle atthesame time .
(1)OJNoL42.,23February 1970
(2)OJNoC,125 *28November 1968 .

These results have been ,submitted -to ,,the ;Commission 'sgroup of
experts on"Motor vehicles "which hasdelivered -apositive opinion .
However ,some experts expressed hesitation with regard ,tothe nuin-
; *
ber ofdegrees laid down forthe angles ofbinocular obstruction
(itèm in'Axinèx' I).
vTheinitial redrafting' ofthepi-oposal foradirective -ofJuly 1968
was soextensive that theCommission felt itworthwhile toput
1 forward anewproposal for adirective . *
