More than 6,600 motorists were arrested in the month-long Christmas and new year campaign targeting drink and drug-drivers, according to new figures released by the Association of Chief Police Officers (Acpo).
Officers across England and Wales stopped and tested 169,838 people during what was said to be the coldest December since records began.
Of these 6,613, or 4% of those stopped, were found to be driving under the influence of drink and drugs, putting the lives of other road users at risk.
The campaign, which ran from December 1, 2010, to January 1, 2011, saw an average of 207 drivers being arrested every day for breaking the law.
Chief Constable Mick Giannasi, theAcpo lead for roads policing, said: "That is not only socially irresponsible, it will also have consequences for those who were caught.
"All of them now face a lengthy driving ban, some will face imprisonment and many will already have lost their jobs and their livelihoods.
"Driving under the influence of any substance, whether it is alcohol or drugs, is not acceptable."
The figures also reveal that a higher number of accidents are caused by people who drive under the influence of alcohol.
