A 75-year-old bicyclist is in the hospital after being struck by a car in Mililani early this morning, according to the Honolulu Police Department.

As a result of the collision, he was ejected onto the roadway. The driver, a 43-year-old man, was not injured and remained at the scene.

Honolulu Emergency Medical Services responded to the scene and administered advanced life support.
