asked the Minister of Transport what percentage of drivers he estimates use dipped headlights in cities during hours of darkness; and what percentage drives on parking lights alone.
The last survey carried out by the Department, which was in 1978, suggested that on average about 76 per cent. of drivers used dipped headlamps in large towns at night while 24 per cent. used sidelights only. A more recent survey by the night safety advisory bureau suggests that there may have been a slight increase since then in the percentage using headlamps.
