Can you have your neighbor's car towed away if she parks in your driveway?
In practice this is very difficult to do anything about. I know because it happened to me. The police weren't interested unless any damage was done to the property, and the council weren't interested unless the pavement was being blocked. Similarly, I am a lawyer and my litigation colleagues said there was pretty much nothing I could do about it except stick a sticker in the window asking them not to park there.
It must depend on your jurisdiction. If a car blocks your driveway, preventing you from accessing it, the car can and will be towed by the local police and a citation will be issued. Most municipalities in the United States have town and city ordinances regarding how close a driver can park to a driveway. For example, there is a five foot limit locally. The police are happy to oblige when a property owner complains. If the car is parked on private property it certainly can be towed. If you are the owner of property no one else has the right to park their car in your driveway unless you have given them permission.
