ANNEX A
LOCATION AND INSTALLATION OF LIGHT SIGNALS A.1 Location and installation of light signals will take into consideration the plans of tr affic organization drawn up during specific research activities, with the observance of all distances prescribed in STAS 1848/1-71 and the approval of those police units which are responsible for the safety of the traffic.
A.2 The support system will be made of concrete steel or metallic piles, which have been produced for common use or especially for this purpose.
A.3 In case of roads with multiple lanes, when each of them shall be provided with specific signaling, light signals will be supported by means of a girder system or lugs. NOTE: The support of light signals on metallic lugs fixed on the walls of existing (and permanent) constructions is permitted in extraordinary cases with the approval of the technical authorities which are responsible with all systematization processes.
A.4 Light signals will be replicated and fixed on lugs at a proper height so that it would be perceived in those areas where the road circuit displays difficulties i n traffic signaling due to its configuration or due to the traffic.
A.5 Display of other types of signals such as commercials, which may diminish the meaning of the traffic light signal or distract the drivers, is prohibited in difficult areas.
