A police summer drink drive campaign ‘Is it worth the risk?’ saw 239 people arrested for driving over the limit or refusing to provide a specimen.
The campaign, which ran from June 1 to June 30, resulted in five more arrests than in the same period last year, with 106 of the arrests in Berkshire and 69 in Buckinghamshire.
Officers carried out almost 3,000 tests in June, with men making up 84 per cent of those arrested.
The campaign targeted 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.
In total, 99 of the arrested people have been charged, with 95 bailed, one cautioned and 44 released with no further action.
Superintendent Henry Parsons, head of roads policing for Thames Valley, said: "Although our drink drive campaign finished on July 1, we focus on arresting drink drivers 365 days a year.
"Our message is that if you drink and drive, we will be looking to arrest you and put you before the courts. If you’ve been drinking, don’t drive. It’s too dangerous and not worth the risk."
