Northamptonshire & Cambridgeshire Police have launched their annual Christmas crackdown on drink driving.
Officers are stepping up patrols in both counties to make sure motorists don`t take to the wheel after having alcohol.
The forces are warning people caught will be fined, lose their licence, their job and could even go to prison if they kill or seriously injure someone.
Also Cambridgeshire Police has launched a scheme where designated drivers are being offered free non alcoholic drinks across the city.
The campaign also applies to people getting behind the wheel under the influence of drugs.
