One of the stories on that page is ‘Drunk driver slams into cop car’.
I saw that happen in the late Eighties in I-680 just south of San Ramon. My ex and I were coming home from her parent’s house one night, and saw a burning CHP unit on the side of the road. Another CHP unit was there- I think the officer was trying to keep the injured one going until the EMTs got there. I laid out a flare pattern and lent some blankets at the officer’s request. The assisting officer and I talked it over and agreed that the fire wasn’t going to get any worse, and was providing heat and light, so I didn’t get my extinguisher out.
My ex called the hospital and found that the injured officer was going to be OK, never heard anything else about it. I still wonder how it played out in the end. The cop who was down didn’t look like he was doing so well when we got there.
Anymore it gets pretty hazardous just putting on your 4 ways & slowing down near accident scenes.
