Crash On The Freeway

So there I am coming home from work on I-15 and I see a bunch of car's brake lights coming on so I slow down. Then I notice whilst the cars are almost at a stop on the left the right two lanes are still unclogged. So I change lanes and go by the congestion when on my left I see a car has smashed into the first county freeway truck that has the big arrow flashing to go right.
Out of the corner of my eye I see the silhouette of a man on all fours on the shoulder. I pulled over and got out of the car- it looked like he was injured.

I jog about 60 yards to the scene of the accident and find him sitting on the ground with his back resting on the freeway divider with the freeway truck driver and a girl who is crying. I ask him where it hurts and as I wait for his answer I hear the squeal of brakes and turn to see a speeding car that is trying to get out of the far right lane where his smashed car was. The girl starts to run then stops when the car avoids causing another accident. I turn my attention back to the man who has now stood up but hear another squeal of brakes and turn to see a pickup truck narrowly miss his wrecked car by veering onto the shoulder we were standing on.
I shout to the two car occupants to move further down the freeway and I turn to the driver and ask him if he has any flares. He says they are behind the seat of his truck and for me to get them because he is calling 911.
I run to the truck and can't get behind the seat. Two other drivers from two other trucks come walking up slowly and I wave at them to come over and direct them to get the flares. The lead driver looks at me stupidly and I turn and go back to the first driver and tell him to get the flares and I'll call 911.
So, in a couple minutes the flares go up as I try to get the 911 operator not to put me on fucking hold. WTF is that all about? Jesus Christ, this was an accident waiting to happen and you're gonna fucking put me on hold??? FUCK!
So he tells me they are already responding to the first call from the driver so I hang up and take some pics and see the ambulances and fire trucks coming into view. Don't know why five Highway Patrol cars weren't there like they were when they tried to arrest me three days ago.
I turned to the young man and tell him to get a lawyer, that this is bullshit, it's very unsafe. I told him to make sure he and his girl go to the hospital to get checked out.
Then I make my exit. The situation was under control.
Like most ADDers I may not be able to balance a checkbook or keep my room tidy but I am damn good in an emergency.
