Ride with a cell phone, personal identification, emergency contact, and something to write with.
Dial 911: call the police or an ambulance immediately. If you are unable to do so, ask someone to help.
Always wait for the police to arrive and file an official accident report. A police report provides documentation detailing the incident, including the identity of witnesses.
Get the business card of the officer.
Leave your bike in the same state it was after the accident, if possible. It is best if the police see the accident scene undisturbed.
Obtain the contact information of any witnesses.
Immediately seek medical attention, either at the scene, the emergency room, hospital or doctor's office. When in doubt go to the ER! Give all complaints to the doctor. Medical records are proof that you were injured and document the extent of your injuries.
Take photos of injuries and keep a diary of how you feel after the accident.
Never negotiate with the driver of the vehicle, regardless of who may be at fault. Get the driver's name and his or her insurance information, along with the names of any passengers.
Give no written or recorded statements to anyone.
