Although he does not have a California motorcycle license, the actor and politician has spent weekends for the past 20 years riding his Harley-Davidson bikes, The Los Angeles Times reports. Sunday, he had his 12-year-old son Patrick in a sidecar when the SUV pulled out of a driveway in front of him.
Schwarzenegger required 15 stitches to close a gash on his upper lip, but his son escaped injury.
"I knew if I would turn left, that the Republicans would get mad. And if I turned right, my wife would get mad, so I just crashed right into the car," Schwarzenegger joked with reporters.
The crash occurred about four years after another motorcycle accident in which he broke six ribs.
Los Angeles Police Lt. Paul Vernon said no citations have been issued because the investigation is continuing.
