The Honolulu Police Department, along with transportation officials and others, are urging the public not to drive under the influence of alcohol or drugs this Fourth of July.

Police will continue impaired-driver checkpoints at undisclosed times and locations across Oahu, including today.

“As we approach Independence Day, the HPD encourages everyone to drive safely and with kindness,” said HPD on Instagram and Twitter posts last week. “Let’s make good decisions and spread aloha on the road this weekend and beyond.”

State Department of Transportation Director Ed Sniffen urged people to make plans ahead of time if their celebrations will include alcohol.

“We’d love everybody to get back home to their families after all the celebrations are done. So I ask everybody who’s going to drink, set a plan to ensure that you don’t drive,” he said.

Sniffen said more than 50% of traffic-related fatalities in the state involve motorists who were driving while intoxicated or impaired.

He also urged drivers to follow the speed limit and be aware that many people will be out and about during the holiday, including pedestrians and bicyclists. He also urged those on foot and on bicycles to follow the laws as well and keep safety in mind.

Mothers Against Drunk Driving Hawaii said the message not to drink and drive also applies to those operating boats on the water. “You wouldn’t drink and drive,” MADD Hawaii said in a Facebook post, “so you shouldn’t drink and boat.”
