The number of people caught drink driving over Christmas has fallen by almost a fifth.
Police carried out more breath tests last month but fewer drivers tested positive for alcohol.
Motorists took 155,000 tests in December, which was 6% more than the year before, and 7,800 proved positive.
This compares with 9,700 drink drivers caught in the 2006 drink drive campaign.
Drug drivers were also down, with 153 arrests compared to 251 the previous year, according to the Association of Chief Police Officers.
Steve Green, ACPO head of roads policing and Chief Constable of Nottinghamshire said: ‘While just one person drinking and driving is too many, the fact that we have tested 10,000 more drivers than during the last campaign, yet arrested some 20% fewer, is encouraging and indicates that increased enforcement and a hard-hitting campaign may be starting to have an impact.
‘Those arrested will now be brought to justice and face potentially life-changing consequences, with disqualification, a fine or imprisonment all possible results for their actions.’
