This is based on the thread Property Owners & Injury Liability w/ Signage (US, WV) on this site and the comments on my answer there.
This is specifically about the law in West Virginia, but nswerd for other jurisdictions would be welcome.
§61-3B-3. (Trespass on property other than structure or conveyance.) of the West Virginia Code provides that:
(a) It is an unlawful trespass for any person to knowingly, and without being authorized, licensed or invited, to enter or remain on any property, other than a structure or conveyance, as to which notice against entering or remaining is either given by actual communication to such person or by posting, fencing or cultivation.
Suppose that a landowner in West Virginia has a fence around a property consisting of land and a house, with a latched but not locked gate. Suppose further that there are signs at regualr intervals along the fence saying "No Trespassing. No Entry. No Exceptions."
Now suppose that a private person lifts the latch, enters the property, and knocks at the front door of the house. The person may be a door-to-door seller or political agent, or a neighbor. The person intends no unlawful act, such as theft. The person has no official purpose.
Is such a person legally a trespasser under §61-3B-3., whether or not prosecution is likely? If the person is not, what law or case law grants the right to enter the property in spite of fence and signs? I am looking for a specific citation or authoritative source.
Edit after an answer was posted
(a) A possessor of real property, including an owner, lessee or other lawful occupant, owes no duty of care to a trespasser except in those circumstances where a common-law right-of-action existed as of the effective date of this section, including the duty to refrain from willfully or wantonly causing the trespasser injury.
I am particularly interested in whether the hypothetical non-official person is a trespasser the the degree that the "no duty of care" language from §55-7-27 applies,
