ROAD safety campaigners claim lives are being put at risk by cuts in the number of traffic police, with figures showing Scotland's largest force has lost more than 50 officers in four years.

Road safety charity Brake said more resources were needed to combat drink and drug driving, speeding and other offences as enforcement of traffic laws was the most powerful deterrent to illegal motoring.

Figures show Strathclyde Police lost 54 (15%) dedicated traffic officers between 2007 and 2011 – the highest drop across Scotland. However, the force claimed the Brake statistics did not reflect the full resources channelled into the "very high priority" area of policing.

Strathclyde had 290 dedicated officers over its central and eight divisional road policing units in 2011, down from 343 in 2007.

However, a spokeswoman for the force said every officer was involved in meeting "challenging targets" for all motoring offences.

By contrast, Lothian and Borders Police increased its quota of traffic officers by 11 and Grampian boosted its team by 17 over the same period.

Julie Townsend, Brake's deputy chief executive, said: "Road crashes constitute a huge social and economic burden, because of the awful implications for those bereaved and injured, and the strain on health and emergency services. Investing in roads policing, and stepping up critical checks like breath-testing, helps stop crashes before they happen, meaning fewer families suffering and reduced costs to the taxpayer."

Overall, Scotland lost the smallest number of traffic officers in the UK over the period, with a reduction of just 18 officers (-3.6%) across the country. This compares to losses of more than 9% in England, 37% in Wales and 7% in Northern Ireland.

Scotland also recorded the only increase in the number of regular police officers in the UK.

Brake's figures come as significantly fewer motoring offences are recorded north of the Border.

There were 27,530 fewer motoring offences logged in Scotland in 2011 compared to 2007, with 3134 fewer drink-drivers facing prosecution and 23,077 fewer crimes of speeding recorded, according to figures held by the Scottish Government.
