There are a few things you can do to find out if someone has been in a car accident. First, call the police. If you know the person’s name and address, they may be able to provide information about the accident or their injuries. Second, check social media sites such as Facebook and Twitter to see if anyone has posted about the accident. Third, look for news articles or blogs that may have coverage of the accident. Finally, contact your insurance company to see if they have any information about the accident or who is responsible for it.
