N.Y. Nassau County. I own the last house on a narrow dead end street. over the years everyone sped down to the end of the block to pull in my double driveway to make their u-turn. They have killed the tree in front of my house from banging into it so many times, trying to make a u-turn. I have walked out of my front door into my circular drive and almost been run over by people speeding thru it to make a u-turn. I have been sitting on the floor in my driveway doing gardening and felt the heat of a car exhaust on my legs cause someone was backing into my driveway trying to make a u turn and didnt see me.I almost killed the 2 little girls down the block more than once cause I came home and pulled into my circular drive and they were sitting there on the floor hiding and playing. I've had many fights with my neighbors over this and started pulling in their driveways to get the message across to them and it finally stopped. Now a new young couple moved in next door into a tiny little bungalow and its started again. they have no room to move their cars so they are constantly in my driveway. I hear their car coming down the block actually picking up speed to quickly pull into my drive. Yesterday I walked across my property into my drive just at the exact moment someone was pulling into my drive to make a u turn and I actually touched their car in an instinctive attempt to stop it from hitting me. they apologized but I could've been hit, What do I do about this? Is my driveway private property and are they trespassing ? I dont want to put a fence up across my frontage.How do I handle this before I get run over on my own property.
