Honolulu police were called to Waipio Saturday morning after a car crashed into a pole at the intersection of Kamehameha Highway and Ka Uka Boulevard.
That was around 8:30 a.m.
Police say a 45-year old Waipahu man was driving the car.
He was taken to Pali Momi Medical Center in critical condition.
Speed and alcohol are not factors but police think he may have suffered a medical condition just before the crash.
