State Sen. Lorraine Inouye, who introduced a bill that in 2017 increased the speed limit on portions of the Daniel K. Inouye Highway from 55 mph to 60 mph, said she thinks it’s time to roll the speed limit back to 55.

Inouye, a Hilo Democrat, told the Tribune-Herald fatalities on the Big Island’s main east-west thoroughfare — also known as Route 200 and Saddle Road — are “very concerning,” and she’s considering introducing a bill in the 2026 legislative session to return the speed limit to 55 mph.

According to Inouye, she was “happy when that highway was completed” in 2013, mostly with federal funding.

“I was the one that told state Highways Division, ‘Let’s consider raising the speed limit in the appropriate areas’ at the time the road was dedicated,” Inouye said. “And I did that by law.

“But, nonetheless, I think I’m going to make an amendment to take away that benefit for our drivers. It’s the drivers who are minding the speed limit who get hurt. That’s why, for me, it’s very bothersome. This is addressing those who are being killed by the drivers who are speeding.”

The most recent fatal crash was on Oct. 23, a head-on collision that claimed the lives of 47-year-old Anina Masaichy and her 3-week-old granddaughter. Four other passengers in the Subaru SUV Masaichy and the infant were in sustained serious injuries — a 4-year-old boy, 17-year-old girl, 18-year-old woman and 51-year-old man.

The driver of the other vehicle, 43-year-old Kimo Medeiros of Kurtistown, allegedly caused the crash and has a long history of traffic offenses. He was cited just three days earlier for driving without a license.

Medeiros was charged with two counts each of manslaughter, first-degree negligent homicide and third-degree promotion of a dangerous drug; three counts of first-degree negligent injury; plus reckless driving, driving under the influence of drugs, marijuana possession, and driving without a license.

Medeiros, who was driving a Toyota Tacoma pickup truck, was indicted Nov. 3 by a Hilo grand jury. His bail is set $2.055 million.

Inouye said state Transportation Director Ed Sniffen supports her idea for the speed limit reduction.

An email from the state Department of Transportation said agency officials believe “setting speed limits on DKI Highway/Saddle Road that are consistent with the characteristics and surrounding land use will improve safety. Especially with the recent fatal crashes involving speed and head-on crashes on DKI Highway/Saddle Road.”

An Oct. 28 press release by the Hawaii Police Department urged motorists “to drive responsibly following a recent increase in reports and incidents involving reckless and dangerous driving.”

As of October, officers had issued over 9,200 speeding citations, compared to 9,088 citations issued in all of 2024, the release said.

Police said “a significant majority” of excessive speed citations and arrests this year have occurred along the DKI, underscoring the ongoing danger associated with speeding and reckless behavior on the highway.

“It’s a known fact that speed kills. It’s just physics,” said Reed Mahuna, interim police chief. “The faster you’re going has an impact on injuries and fatalities. I don’t think the police department would ever be in a position to be opposed to a reduction in the speed limit.

“I would say that people who are driving 60 mph on that stretch of roadway and driving legally and safely are not necessarily the problem,” Mahuna added. “The fatal crashes that we have, people are driving recklessly. They’re driving in excess of 60, or they’re driving 60 when the road conditions aren’t safe — in heavy rain, for example, in fog or in other situations where it creates an unsafe road condition by the manner in which they’re driving.

“I think that we, as a community, have to look at ourselves in the mirror and decide that we’re going to drive safely, that we’re going to care for one another — especially our keiki and our kupuna, the most vulnerable among us — and that getting somewhere two, five or 10 minutes earlier is not worth putting ourselves, our family and our community family at risk. I think that’s the turning point.”

“We, as a police department, we’re going to continue to do our enforcement, we’re going to aggressively look at ways that we can reduce fatal traffic crashes on the island,” Mahuna concluded. “But I think that all of us, working together, is going to be the turning point when we can finally say enough is enough.”
