A 19-year-old moped rider and her passenger were seriously injured in a hit-and-run in McCully Monday.

Honolulu police said a 2001 Ford pickup truck operated by an unknown male was traveling east on Kapiolani Boulevard and attempted to make a left turn onto Pumehana Street when the vehicle collided with a 2020 moped operated by a 19-year-old woman traveling west on Kapiolani Boulevard at about 7 p.m.

The moped rider and her passenger, a 19-year-old woman, were taken in serious condition to a hospital. Both were wearing helmets at the time of the collision.

Police said the pickup truck driver fled the scene.

Speed does not appear to be a factor in the crash. It’s unknown at this time whether alcohol or drugs were factors.
