First and most importantly, make sure that you and everyone else is okay and then get help for the injured. The next crucial step is to make sure to notify the police so that they can file a report. The police report is the most accurate and court relevant information available. Keep a notebook in your vehicle for taking down important information. Make sure to get names, addresses, phone numbers, driver’s license number, license plate number, car make and model numbers, witness phone numbers, etc. The more information that you can gather, the better. Also, if you or passengers are injured, make sure to save all medical bills and receipts.
