A woman in her 30s was critically injured and taken to a trauma center Thursday afternoon after the moped she was riding struck a parked car.

The woman, along with an adult male passenger, were riding southbound on Fort Street toward South Beretania at about 5:30 p.m. when she lost control, drifted right and struck an unoccupied parked car, according to Honolulu police.

The woman, who was not wearing a helmet, was ejected onto the roadway upon impact, police said. The man fled the scene on foot.

Paramedics administered advanced life support to the woman before she was taken to the trauma center in critical condition.

Speed, drugs, or alcohol do not appear to be involved in the collision, police said.
