Unfortunately, you will likely be involved in a car accident at some point. Preparing is one of the most important things that you can do to deal with the aftermath. The well-being of everyone involved is of the utmost importance. Check to see if anyone has any injuries. If someone is injured, then you should call emergency personnel. Move your vehicle if it is safe for you to do so. Another accident is likely to occur if your vehicle is in the middle of the road.
Keep in mind that in some places it is required to report the accident to the police even if it is a fender bender. You are required to stay the accident scene until the police arrive. You may want to take pictures of the scene if you plan on filing a claim with the insurance company.
