The chase began around 11 p.m. when the driver of a Volkswagen sedan committed minor traffic violations and refused to stop for police, authorities said Tuesday.
The crash at Barranca Avenue and East Puente Street, about a half-mile north of Interstate 10 in Covina, occurred at about 11:45 p.m. Monday.
The Volkswagen collided broadside into a Mazda, according to the Los Angeles County Fire Department.
The driver of the Mazda suffered a fractured neck and a broken pelvis, Pasadena police Lt. Thomas Delgado said.
The driver who instigated the chase struggled with police before he was arrested on suspicion of felony failure to yield, Delgado said.
He was under police guard at a hospital, Pasadena police Sgt. Roger Roldan said just after 3:30 a.m.
It was not known if the man was under the influence of alcohol or drugs.
