Sussex Police have tested 948 drivers on suspicion of drink-driving during the first week of a summer campaign.
A total of 38 arrests were made and among those was a 45-year-old man who was charged with being nearly three times over the drink-drive limit.
The man, who had a child in his car, was stopped at 0830 BST on 9 June on the A27 near Eastbourne.
Ch Insp Di Roskilly said: "Drunk drivers take lives and ruin lives."
She added: "We are removing a growing number of drunk drivers from the roads of Sussex before they have come to any harm or caused injury or worse to other road users.
"We are doing all that we can to discourage drinking and driving, but it is disheartening to find that there are still those who blatantly disregard the law and are prepared to gamble with their lives and the lives of others."
