Lincolnshire Police stopped 104 motorists in Lincoln this morning in just one hour during the offical launch of its Christmas crackdown on drink and drug driving.
Drivers were ordered to pull off Skelllingthorpe Road between 7.30am and 8.30am and were handed campaign leaflets.
Twenty people were breathylsed but no-one tested positive.
The countywide campaign runs from December 1 to January 1 and roadside tests are being carried out across the county during the mornings, evenings and night time.
As well as breathaylser checks, field impairment checks will be carried out on drivers suspected of driving under the influence of drugs.
Chief Inspector Stewart Brinn said: “Families torn apart by the spectre of drink and drug driving are left behind to suffer for all time the loss of a loved one.
“Our enforcement strategy will include leaflets in 3 languages, Latvian, Lithuanian and Polish as well as an English leaflet.
“We will conduct checks at all times of the day to ensure drink and drug drivers are stopped and put before the courts.
“Information from Crimestoppers will be acted upon swiftly to ensure the safety of road users in Lincolnshire.
“We ask members of the public to help us to help them. Call 101 if they suspect a drink driver but call 999 in an emergency."
Lincolnshire Road Safety Partnership says that everyone has a responsibility when behind the wheel to ensure they are fit to do so.
Impairment through drink or drugs carries severe penalties for those convicted and those who refuse testing will suffer the same penalties through the courts.
People enjoying the festive period are urged to make provision to travel by nominating a designated driver or pre-arranging a taxi home.
Drink drivers can be imprisoned, they will automatically be banned from driving for 12 month and the offence will remain on their license for 11 years.
The criminal record for the offence will be declarable for all times.
So far this year in Lincolnshire, two people have died in drink-related collisions and 69 people have been injured, 13 suffering serious, which are often life changing, injuries.
Lincolnshire Police roadside test more than 12,000 people every year and more than 800 have been prosecuted so far in 2013.
