Emergency Medical Services transported a 35-year-old man to a hospital after he sustained critical injuries in a single-vehicle crash in Wahiawa early today.

The crash occurred at about 3:15 a.m. near Green World Coffee Farm at 71-101 N. Kamehameha Highway.

Police said a 2015 Nissan four-door sedan was traveling northbound on the highway when it crossed into the opposite lane and veered off the road.

The vehicle then traveled up an embankment and landed in the coffee farm.

EMS treated and transported the Schofield Barracks man to an area hospital in critical condition.

Police said speed and alcohol may be involved.

Police temporarily closed the highway between Kamananui Road and Kaukonahua Road to investigate. Officers reopened lanes at about 5:45 a.m.

The investigation is ongoing.
