Eight Hawai‘i Island police officers and two deputy prosecuting attorneys were honored on May 2 by Mothers Against Drunk Driving Hawai‘i (MADD Hawai‘i) and Toyota Hawai‘i for their efforts to reduce accidents and fatalities on roadways in Hawai‘i by impaired drivers.

“These law enforcement recognition events underscore the close relationship between MADD and law enforcement—police and prosecutors,” said MADD Hawai‘i’s Chairperson of Victim Services, Theresa Paulette. “They are MADD’s most critical allies in the fight against drunk driving. We are deeply grateful to Toyota Hawai‘i for its enthusiastic sponsorship.”

Toyota Hawai‘i has sponsored and partnered with MADD Hawai‘i since 2012 to host statewide annual law enforcement recognition events.

“There is never an excuse to get behind the wheel intoxicated or impaired,” said Glenn Inouye, senior vice president of Servco, representing all Toyota Hawai‘i dealers. “We’re honored to partner with MADD Hawaii to raise awareness about the critical need to stop impaired driving and salute our police officers who have saved lives in this effort.”
