The number of people arrested as part of the Police anti-drink drive campaign rose during 2018.
23 were made during the campaign in December, up from 14 for the same period in 2017.
Officers add 349 vehicles were stopped across the Island as a direct result of the operation last month.
Sergeant Jamie Tomlinson of the Roads Policing Unit says the constabulary 'remains committed to tackling drink driving all year round'.
