Kaua'i police will join the other three counties in conducting drunken-driving checkpoint stops from the Admissions Day weekend through Labor Day.

The program is part of a nationwide "Drunk Driving, Over The Limit, Under Arrest" campaign.

"We are glad to be a part of this nationwide campaign and in helping to keep a safe and healthy community during the holiday weekends," said Lt. Mark Scribner of the Kaua'i Traffic Safety Unit.

A new state law distinguishes between intoxicated and highly intoxicated drivers. More severe penalties apply for blood alcohol levels higher than 0.15 percent, nearly double the standard 0.08 percent alcohol limit.
