The Medical Examiner Office identified a 16-year-old girl killed in a scooter accident.

Nicolette Vares, of Kapolei, died Thursday at Queen’s Medical Center, where she was taken after she lost control of the green Vespa scooter she was driving and crashed into a guardrail on the Likelike Highway onramp to the H-3 Freeway.

Speed and inexperience may have been factors, said Traffic Division Lt. Robert Towne.

The onramp has a 25 mph speed limit and a sharp bend that “catches you off guard,” he said.

Towne said the girl’s father was following her on his motorcycle and witnessed the crash.

It is the third motorcycle fatality in the last 18 months.

An autopsy will be conducted Friday to determine the exact cause of death.
