THE percentage of drivers that tested positive for drink driving in the West Midlands fell by 0.1 per cent during the Christmas campaign.
More than 20,000 drivers were stopped in the Birmingham and Solihull area, over 4000 being breath-tested.
Over the same spell, the number of collisions reported increased by 10.3 per cent but the percentage of positive breath-tests from collisions fell significantly from 8.3 per cent in 2007 to 5.4 per cent.
Insp Clive Isherwood, from West Midlands Police Road Policing Unit, said: “The campaign saw a significant increase in the number of vehicles stopped and breath tests carried out.
“Although the drink drive message appears to be getting through to a lot of motorists, many more continue to ignore the warning.”
