Derbyshire Police have revealed that almost 20% of the 391 motorists tested gave a positive test, refused to take it or failed to provide a sample during its Christmas drink drive campaign.
The force also worked with Crimestoppers who offered a reward of up to £1,000 to anyone who called the charity to report a drink-driver, if the information lead to an arrest and charge.
27 people reported a drink-driver during the campaign.
The campaign this year was intelligence led and we carried out targeted breath testing where we had information to suspect drink-driving. This led to a higher percentage of motorists giving a positive test, refusing or failing to provide despite us carrying out fewer tests.
