More than 4,600 drivers were breath tested in Norfolk and Suffolk during the Christmas drink drive campaign.
During the month long crackdown 4,647 drivers were tested with 188 motorists providing positive readings.
Roads policing officers carried out extra patrols between December 1 and January 1, stopping vehicles through concern over the manner of driving, vehicles with faults and testing anyone involved in a collision.
In Norfolk 2,457 tests were carried out with 79 people providing positive readings while in Suffolk 2,190 people were breath tested with 109 positive readings.
Chief Inspector Chris Spinks, head of the Norfolk and Suffolk Roads Policing Unit, said: “The number of tests carried out in comparison to the positive readings shows it is still a minority of people who take risks by drinking and driving.
“Drivers thought to be under the influence of drink are stopped and tested all year round but the seasonal campaigns give us the opportunity to highlight the dangers associated with getting behind the wheel while over the limit and the consequences of being caught.
“It is always disappointing to see people ignoring the message; I still find it surprising to find people taking such risks with their own safety as well as the lives of others.
“People caught drink driving will not only have a criminal record but will almost certainly lose their licence and means not only will you lose your licence but you may even lose your job. In the most serious cases the consequences of your actions could cause serious injury or even death. The risk simply isn’t worth it.”
Ch Insp Spinks added his thanks to local media, Crimestoppers and partner agencies for supporting the campaign and helping to spread road safety messages.
Last year 5,547 drivers were breathalysed in Norfolk and Suffolk with 204 positive tests.
