Auto Accident During U-Turn

If you are making a safe legal u-turn and car reverses into you through street parking spaces who is at fault?

If it was a legal u-turn, and you had established yourself in the other lane, the other driver had a duty to not enter your lane until it was safe to do so. So, you have a legal right to pursue the other driver for your damages. Of course you should expect that their insurance will contest the matter given the nature of the accident. However, that doesn’t mean you can get paid for your loss. Good luck.
