TIP: Take photographs of your injuries and the damage caused to your vehicle. While its probably the last thing on your mind at the moment, preserving the evidence at the scene of the accident is important. If you have a camera equipped cell phone, you can quickly and easily take pictures of the scene to be referenced at a later time when emotions have cooled.
BONUS TIP: Draw a Diagram Make a diagram of various landmarks (like stores, benches, lampposts, signs, etc.) and indicate the direction and flow of vehicular and pedestrian traffic.
