A report from California Highway Patrol Officer Adam Garcia said the collision took place at 6:30 p.m. Tuesday.
Michael Green, 51, of Kelseyville was riding his Honda ATV four-wheeler southbound on Live Oak Drive north of Cole Creek Road when he drove straight as the road curves right, according to Garcia's report.
Green traveled down a dirt and brush embankment before coming to rest approximately 100 feet down the hill, Garcia reported.
Garcia said Green was not wearing a helmet.
REACH air ambulance transported Green to Santa Rosa Memorial Hospital by REACH, Garcia reported.
Alcohol is believed to be a factor in this collision, according to Garcia, and consequently Green was
arrested for suspicion of driving under the influence.
Due to the extent of his injuries, Green was released to the care of the hospital, according to Garcia.
Officer Dallas Richey is investigating the incident, Garcia said.
