Five arrests by day four mark the launch of the annual Christmas drink-drug drive campaign across Lincolnshire.
Drivers are being warned police will be conducting roadside checks and prosecuting those who drive while under the influence of drink and drugs.
So far this year two people have died in drink-related collisions in the county, 13 have suffered serious, life-changing injuries and 69 have been injured.
Annually there are in excess of 12,000 roadside breath tests and more than 800 drivers have been prosecuted this year.
Spalding police will be targeting ‘morning after’ drivers, as well as those out at night,
Ins Jim Tyner said: “The consequences of drink - drug driving have a devastating effect on our communities. Local officers, together with roads policing teams, will be active throughout the festive period, making sure those who get behind the wheel are fit to do so and not putting the lives of others at risk.
“We will be targeting the ‘morning after’ drivers, as well as those out at night, and will be carrying out field impairment tests on those suspected of driving under the influence of drugs. It’s very easy to make alternative arrangements, such as ordering a taxi or nominating a designated driver.
“Enjoy Christmas and start 2014 alive and well, and without the death of another person on your conscience”.
Members of the public are being urged to assist police by calling 101 if they suspect a driver has been drinking.
