Thames Valley Police arrested 10 people in both Bracknell and Wokingham during its ‘is it worth the risk?’ campaign last month.
The number rose from eight in Bracknell and seven in Wokingham in 2012.
Henry Parsons, Chief Inspector for Thames Valley Police and Hampshire Constabulary’s joint roads policing unit, said: “It’s worrying that some people are still making the wrong choices, deciding to drink and drive when there are alternatives available. Drink-driving is dangerous and it kills or seriously injures many people each year, devastating families.
“I’m grateful for the public support for this campaign that has helped us to be in the right places, at the right times to make these arrests.
“We’ll continue to target drink drivers every single day of the year, not just during campaign periods. It isn’t worth the risk.”
Across the Thames Valley, police arrested 281 people on suspicion of drink-driving between December 1 and January 1 inclusive. A total of 231 men and 50 women were arrested – a 1% increase on the 278 arrests made during the same period in 2012.
There was a 6% increase of men (up from 218 this time last year) and a 17% fall in arrests of women (down from 60 last year).
In total, 161 of the arrested people have been charged, with 82 individuals bailed and 38 people released with no further action.
The campaign saw police targeting individuals they suspected of driving under the influence of drink or drugs, both on the way home from nights out and the morning after a heavy night.
