Capping a dangerous week for motorcycle riders on Oahu, three motorcyclists were injured — one critically — in three separate crashes Saturday night.

The first occurred at about 5:20 p.m., when a man believed to be in his 20s apparently lost control of his motorcycle and crashed on the H-3 freeway near Mokapu Road. He suffered a broken foot and other minor injures.

At 9:27, a man riding an undersize "pocket" motorcycle was apparently clipped by an approaching car on Kamehameha Highway in Haleiwa. According to police scanner reports, the man swerved to avoid the car, which was described as traveling at a high rate of speed, but the impact sent the rider flying some 15 feet across the pavement.

The rider, identified in scanner reports as a 28-year-old man, suffered a broken ankle and other minor injuries. He was taken to a hospital in serious but stable condition.

A few minutes later, another man in his 20s was injured when he apparently lost control of his motorcycle while traveling up Kulia Street near Uluwale Street in Wahiawa and struck a parked car. He was transported to a hospital in critical condition.

The accidents followed two motorcycle-related fatalities last week.

On Tuesday, 43-year-old Warren White of Aiea was critically injured when his motorcycle collided with an oncoming car on Kaonohi Street. White died three days later.

On Friday, a 36-year-old David Keaweehu III of Waimanalo was killed when his motorcycle rear-ended a car on Kapiolani Boulevard near Ward Avenue.

To date, there have been six motorcycle fatalities on Oahu this year, compared with one at the same time last year.
