Two people were killed Saturday after their truck was hit by a car running a red light in Makawao, Maui police said.

Police identified the passenger of the Toyota truck as 57-year-old Traci Winegarner of Pukalani. The identity of the driver, a 63-year-old woman, was being withheld, pending notification of next of kin, police said.

Winegarner was not wearing a seat belt, but the driver was, and both died at the scene, police said.

The crash happened about 10:25 a.m. on Haleakala Highway bypass at Makani Road.

Police said the driver of a silver Nissan sedan was on Haleakala and disregarded the red light at the Makani Road intersection and broad-sided the Toyota truck as the truck was making a left turn onto Haleakala Highway.

The Nissan crossed the centerline and struck a vehicle stopped in the on-coming lane of traffic, which pushed the vehicle into another vehicle stopped behind it.

The driver of the Nissan sustained non-life threatening injuries and was taken to Maui Memorial Medical Center for treatment.

Occupants of the other two vehicles also sustained non-life threatening injuries, police said. In total, five people were taken to Maui Memorial Medical Center for treatment.

Police said speed is suspected to be a factor in the crash.

The incident marked Maui’s 14th and 15th traffic fatalities in 2016 compared to 18 at this time last year.
