Jonathan Olmedo, 32, of Coarsegold, was arrested by the California Highway Patrol for felony DUI following a head-on accident on Road 415 near Coarsegold at about 6:30 p.m. Tuesday.
According to the CHP, Olmedo, a paramedic with American Ambulance of Fresno, was driving his Honda Civic eastbound on Road 415 at about 50 m.p.h. near Trabuco Road when he allowed his vehicle to drift across the center line, striking a westbound vehicle head-on.
The westbound vehicle was driven by Keith Dion, 26, of Hilmar. No passengers were in either vehicle.
Both drivers were pinned in their vehicles and it took first responders an hour to free Dion from his car. Both drivers were air lifted to Community Valley Regional Medical Center in Fresno.
Olmedo was in critical condition with head and internal injuries and Dion suffered a broken right leg.
A CHP officer said Olmedo was under the influence of an "excessive amount of alcohol" at the time of the accident.
Mountain Area fire stations 8, 10, 12 and 13 and Raymond Cal Fire responded to the accident, along with Sierra Ambulance and the highway patrol, including CHP helicopter H-40.
The accident is under investigation.
