What happened:
There is a left/straight lane which is a part of my normal commute. If I'm the first vehicle of the lane at the light I usually position myself toward the right side of lane and little bit further up front so that the car behind me can trigger the turn signal. Yesterday during my lunch ride, I did the same thing. On green light I took off and made a big left turn and I hit a car that was going to straight. I actually did not realize the lane is left/straight until then. I did not have a mirror so did not know the car was passing straight. When I saw the car it was little late to avoid the contact. So my bike handlebar hit the right/rear passenger door of the car and I lost balance ended up falling on my left side. Speed was probably less than 8MPH since I just took off and I landed with my hand/knee/hip. The driver stopped and checked if I'm okay. The driver thought I was going straight. I did not do a hand signal so he tried to pass me. There was an witness and Fire Department crew on the street called the police. I thought I felt fine since it's almost like a simple bike fall not like a crash type of accident. They offered to go to ER but I refused as I did not think it was a serious accident. My wrist soared and my knee was bleeding a bit due to a minor road rash. I actually hit the same spot that I fell last week myself. Police took all information from me and the driver and the witness. Police did not file a crash report though. Left me a card to contact him if anything needed. Bike looks okay except the handlebar tape is ripped.

My condition:
The hip started to soar about an hour after crash. My wrist and knee hurts but I could still ride to home. I checked myself after I got home I think I hit the ground with my left hip bone. I can walk and put weight on my left leg. I'm no expert but I don't think my hip bone is broken or cracked. There is no swelling or noticeable bruise on the left hip. It just feels tight and soar when I raise my knee. It's just bit uncomfortable when I walk. No pain when in rest.

After thought:
I did admit that I did not do hand-signal to the left as I thought it was left turn only lane. But when I think about again the driver was passing me very closely in the intersection. I did not take the whole lane but somewhat close to the middle when I was taking a wide left turn. He should have waited until I cross the intersection. I'm thankful that I did not hit by the front of the car though. I refused to go to ER since I thought it wasn't serious injury. Also I did not cause trouble going ER and hospital bill, legal, etc. I feel bit better today and debating whether I should see a doctor or not.

Lesson learned:
1. Know your route and the types of lanes of your commute. If I knew it was a left/straight lane then I would have avoided this accident by taking a whole lane or making a left turn signal to make myself clear.

2. Take a whole lane on the left turn lane. I positioned myself on the right of the road and letting the first car passed by me was silly of me. They can wait on my left turn and should protect myself rather than yielding to cars behind.

3. Go to ER or get medical help on the scene even if minor injury. You never know what happened during accident so it's better to get checked up. I did not know my hip was hit until an hour later. Getting medical help later is still possible and I'm thinking about it but it would be better to just getting a help on the scene.

4. Talk to the witness to get a full picture of what happened. I thought I know what happened but witnesses can give a second eye of story I did not realize such as the car was too close to me when passing. I did not talk to the witness directly but police did. The witness was blaming the driver and they were almost in fight or something and I did not want to cause more trouble.

5. Protect yourself than motorist. I did not want to make a huge deal out of this minor accident so I went easy and did not report a crash report. But next time I would do that even if it seems minor to protect my right than the motorist.

Conclusion:
Just wanted to share this story to remind other bike commuters or road cyclists to get alerted and be safe on the roads. I started road bike a few months ago and this happened. Probably about 600 miles or so on the road. Thank God that it was a minor accident but my confidence on the road is bit damaged and won't ride until my hip is healed completely. I see it as a warning sign to be safe on the roads. Any advice or comment would be appreciated.
