Tustin police shared a photo of what appears to be a metal bolt on a long wooden pole sticking through the top of the car's windshield and nearly touching the steering wheel, with shattered glass in the interior. It looks to be about two feet long.
It happened on Tustin Ranch Road north of Walnut.
Police say the object was roadway debris that got kicked up into the car.
The photo from inside shows just how close it came to the person sitting in the driver's seat.
The woman inside the car was not hurt.
