This has been covered before, but I feel it's an important reminder. . .
After an accident always get ALL of the information from the Driver that hit you even if you don't think your hurt, or if you can't find damage to your bike/equipment.
This past Friday a car merged into me sending me flying across their hood and the street. I was able to get up after the accident, and therefore I thought I was alright. I felt that my wrists were sore, but I thought it was just minor bruising. The driver did stop and paid me $50 for my ripped up bar tap and untrued wheel. Half an hour after the accident my wrist still felt soar, but I had a feeling that the pain was only temporary. About an hour after the accident the there was minimal pain in my right wrist, but my left wrist became incredibly sensitive and painful. Within 2 hours after the accident my left wrist wasn't able to support the weight of my hand. I began realizing that the adrenalin from the accident had masked the injury that occurred during my fall. And now that the adrenalin was gone . . . the pain took over.
***It turns out after X-rays . . . that a part of a bone in my wrist chipped off. The doctors are saying that it's a unique break, and that they may need to insert a pin to piece the bone together.
Being "shaken-up" by the accident, I only took note of the cars license plate, since I didn't think I was that hurt at the time . . . and therefore I though it was unnecessary to take down all of the driver’s information. But now I wish I had taken down all of their information, instead of just the plate number

I'm sure I'll still find the driver using the plate number, but it would be easier with more information.
Like I said, it's hard to think after your life has been put in jeopardy . . . therefore I think we should prepare ourselves with an "after an accident protocol." That way instead of having to improvise on the spot, we already have a game plan to follow.
Just something to think about. I've learned from many of your mistakes/mishaps, and now you can learn from mine
With one arm in a cast and off the bike for gawd knows how long,
