Two women were in critical condition after a one-car crash on Maui, police said.

The accident happened about 1 a.m. Saturday, when the 19-year-old driver of a 2008 Chrysler Sebring convertible apparently lost control on Honoapi'ilani Highway in Waikapu, ran into a ditch and rolled over.

The three occupants in the vehicle were not wearing seatbelts and were ejected.

The driver of the car, a woman from Kīhei, was taken to Maui Memorial Medical Center in critical condition along with an 18-year-old passenger, also of Kīhei.

A 19-year-old man in the car was treated and released.

Police are investigating whether speed, drugs or alcohol were factors in the crash.
