A 19-year-old man was arrested on suspicion of felony DUI Friday morning when Salinas police found him passed out after crashing his car into a pole with his six-month-old son in the backseat. Shortly before 10:30 a.m. Friday, Rufino Valerio was driving north on North Sanborn Road in Salinas when he left the roadway and hit a pole, causing his right front tire to go flat, police said. Valerio continued driving and struck another pole before passing out due to his intoxication level, according to police. Officers arrived and found Valerio’s six-month-old son properly restrained in his car seat with a contusion to his forehead. Valerio was booked into county jail for felony driving under the influence. His son was taken to Natividad Medical Center to be treated for the injury to his forehead. He has been placed into protective custody, police said.
