What can be done about people constantly using your driveway to turn around in?

To address the issue of people using your driveway to turn around, you could consider placing clear signage that indicates "No Turnaround" or "Private Driveway." Another option is to install physical barriers, such as decorative landscaping or a fence, to discourage this behavior. Additionally, speaking directly to frequent offenders, if you feel comfortable, can help raise awareness and encourage them to find alternative routes.
