Almost 100 people were arrested for drink-driving as part of a Christmas crackdown by police.
Officers arrested 91 people in Northamptonshire and charged 68 people during the operation, which lasted throughout December.
The vast majority of arrests were men, with male drink-drivers accounting for 79 of the total arrests and 60 of the charges. Sixteen drivers aged between 17 and 24 were arrested and 12 of those were charged.
Inspector Jen Helm said: “In the not-too-distant past, drink-driving was almost tolerated in society, but now it is increasingly recognised as the reckless and unacceptable behaviour that it is.
“Policing drink-driving through enforcement and raising awareness through education is only half the battle. Every friend, relative or colleague who stopped a drunk or drugged driver getting into a car this Christmas potentially saved a life, or spared an innocent bystander serious injury.
“We will continue our fight against those who drink and drug drive and would like to thank the members of the public who in their own way are saving lives too.”
Last year, officers breathalysed 5,732 people across the county, arresting 115 people. In 2011, 117 people were arrested and 2,532 roadside tests carried out.
