Latest figures show an increase in the number of people drink driving during the recent festive period.
Data from Devon and Cornwall Police’s latest Christmas drink driving campaign show a 0.7 per cent increase in the number of drivers caught over the legal alcohol limit compared to Christmas 2012.
12.5 per cent of the 1,326 drivers who were breathalyzed in Devon and Cornwall last Christmas tested positive for alcohol.
This compares to 11.8 per cent of people in 2012.
During the campaign a 36 year-old woman in Cornwall was found to be more than four times over the legal limit of alcohol per millimetre of blood while driving at 6:30pm in the evening.
In another instance, a 31 year-old man provided a reading three and a half times over the legal limit at 2pm in the afternoon.
Inspector Richard Pryce, a roads policing inspector, said: "Some of the detection results we had are staggering.
"I find it utterly incredible that some individuals will drive after drinking so much as to be three or four times the drink drive limit.They show scant regard for the lives of other people on the road.
"For some, clearly the messages are not getting through. It may be that for these, only the sanction of the law in a court will make them realise.”
However, the total number of positive breath tests following a collision fell by 6.5 per cent during the 2013 Christmas drink driving campaign compared to 2012.
Inspector Pryce added: “The number of breath tests undertaken is down on last year together with the number of positive tests following collisions.
"The overall percentage of positive tests is slightly higher which is disappointing. The positive drink driving figure is still too high.
"Nationally and locally a lot of work is being done to educate people about the risks and dangers regarding drink driving and the messages are out there for all to see.
"As always, catching drink drivers is a year-round priority for us and we will continue to crack down on drink and drug driving to actively contribute to making our roads safer."
