There has been a 20% drop in drink-drive arrests, according to Hampshire police.
The results come from two months of their summer campaign to prevent motorists taking risks.
Since June, 34 motorists have been arrested on the Island.
Chief Inspector Andy Bottomley of Hampshire Constabulary Roads Policing Unit, said: “In June we made the same number of arrests as the previous year but with fewer drink-drive operations carried out, demonstrating that drink-driving is still an issue which many people do not take seriously.
“While we have seen a drop in July arrests on last year – with 183 arrests made this year and 278 in 2011, 183 drink-drivers is still 183 too many.
“Any amount of alcohol can affect the way you drive, creating a slower reaction time and a feeling of invincibility which can cause drivers to take risks.
“There is no excuse for drink driving. If you want to drink don’t drive and if you have to drive, just don’t drink.
“No one’s life is of so little value that it should be risked for a drink. Show some regard for other people – and yourself and just don’t drink and drive.”
