An ingress-egress easement entitles a person the right to enter and leave his or her property. This right is in place even if the person has to pass through another person's property during the entering or leaving.
An easement is defined as a right to use another person's property. Easements are granted for several reasons, including to provide access to public streets or for utility work. For example, if a man's house sits behind a lot owned by a company and his only way to reach the public street is to drive through the company's property, he has an ingress-egress easement. The company cannot prevent him from using the property to access the street.
