It depends on many factors. However, the biggest two factors are often how badly you are hurt, and the amount of available insurance. In most rear end accidents, the person who is rear ended is not badly injured. And in many cases where he or she is seriously hurt, there is limited insurance available. The average rear end car accident settlement is likely under $15,000. That said, some rear end accidents can lead to bigger payouts. For example, in 2019, I settled a rear end accident case for $170,000. My client was a passenger in a car that rear ended another car. You can see a photo of my client's broken arm (humerus) in a sling.
