Should you find yourself in this type of collision, you must first wait for the police to arrive at the scene. Any injuries should be documented, in case they develop into serious medical conditions. Like any accident, never admit blame until you consult with an experienced bike accident attorney. Then, write your side of the story in the accident report. Make sure you get the contact information for all witnesses and the other driver. If there is any evidence, you should also preserve it in case you have to present it in court. It is strongly encouraged that you seek the help of a personal injury attorney to guide you through the process.
