No Trespassing Sign Laws in Arkansas: Signs, Paint, and Fencing

Arkansas no trespassing sign laws let property owners post their land using signs, light purple paint marks, or a sufficient fence, but the required spacing depends on whether your land is forest or not. Forest land must be marked every 100 feet. Everything else can go up to 1,000 feet between markers. Get the spacing wrong and your posting may not hold up when it matters.¹²

Forest Land Versus Everything Else

Arkansas has two separate posting statutes, and the one that applies to your land dictates how far apart your markers can sit. Forest land falls under Arkansas Code 18-11-404 and requires signs or paint marks every 100 feet along the boundary, plus one at every point of entry.¹ Cultivated land, pastures, orchards, and other non-forest property fall under Arkansas Code 18-11-405, which stretches that interval to 1,000 feet.² The Arkansas Department of Agriculture publishes a summary of both.³

Every other specification in the two statutes is identical. Only the spacing differs. If your tract has both forest and non-forest sections, post each portion according to its own standard, or just post the whole perimeter at the tighter 100-foot interval and be done with it.

Posting With Signs

Each sign must say “posted” or “no trespassing” (or both), with letters at least four inches tall, and must be positioned so anyone approaching can readily see it.² Place them around the boundary at the interval your land type requires and at every road, trail, gate, or gap where someone could walk in. Missing a single access point can give a trespasser room to argue they had no notice.

The statute says nothing about sign material, color, or overall dimensions beyond the four-inch letter rule. Durable metal or heavy plastic survives Arkansas weather better than paper or thin cardboard. A faded or fallen sign is no sign at all for enforcement purposes.

Posting With Purple Paint

Arkansas allows paint marks as an alternative to signs. The paint must be light purple and exterior grade.⁴¹²

Paint has real advantages over signs on large rural tracts. Signs get stolen, shot up, or blown down. A painted tree stays painted. The tradeoff is recognition: not every visitor, especially from out of state, knows that purple paint means no trespassing. Some owners use paint for the long runs and reserve signs for roads and gates.

Fencing as a Posting Method

Both posting statutes also recognize a sufficient fence as valid posting.² “Sufficient” is defined by cross-reference to Arkansas’s general fencing laws rather than by a specific height or material in the posting statutes themselves. In practice, a fence that clearly marks the boundary and would deter a reasonable person from crossing it meets the standard. Barbed wire, woven wire, and board fences all qualify. A decorative two-rail fence with wide gaps is harder to defend.

Fencing carries one extra benefit worth knowing: cutting or removing a posted fence is itself a criminal offense, and it bumps the trespasser’s charge up a level.

What Trespassers Face

Criminal trespass in Arkansas means purposely entering or remaining on someone else’s property without authorization. The baseline charge is a Class C misdemeanor, and the classification escalates based on what the trespasser did or carried.⁵

Class C misdemeanor: the default for trespassing on posted property with no aggravating factors.
Class B misdemeanor: trespassing in an occupiable structure such as a building or shed, or removing a posted sign or fence.
Class A misdemeanor: trespassing while carrying hunting or harvesting equipment, bolt cutters, or tools for digging up artifacts; also applies if the trespasser has a prior conviction.
Class D felony: trespassing on critical infrastructure, or a third or subsequent conviction after two Class A misdemeanor trespass convictions.

Pay attention to the second tier. If someone tears down your sign or cuts your fence to get in, that act alone pushes them from the lowest misdemeanor to a Class B.⁵

Arkansas also has a civil provision aimed at recreational use. Entering posted land to hunt, fish, hike, camp, or similar activities without written permission from the owner or lessee can give rise to a civil claim in addition to any criminal charge.

Who Is Not a Trespasser

Before you confront someone on your posted land, know who the law treats as lawfully present. Several categories of people are exempt from criminal trespass when acting within the scope of their duties:⁵

Law enforcement officers performing official duties.
Firefighters and emergency first responders responding to an emergency.
State, federal, and local government employees whose visit relates directly to their job, including code inspectors and child welfare workers.

Several other situations work as defenses if someone is charged:

Guests and invitees, including people invited informally.
Entry for a legitimate business purpose or a health or safety reason.
Property that is generally open to the public.
An adjoining landowner or their employee crossing in good faith for a legitimate reason.
Someone entering solely to retrieve livestock, a dog, or another domesticated animal.

None of these allows the person to damage property or go beyond the reason that brought them onto the land. An inspector can walk the ground for an inspection, not for a hike.

Misusing the Purple Paint

Using the designated purple paint on trees or posts for any purpose other than posting your own land is a Class B misdemeanor. So is posting land you do not own or lease without written permission from the owner.⁶ Casual or decorative use of light purple exterior paint on boundary trees is worth avoiding for the same reason.

Practical Tips for Posting That Holds Up

Meeting the minimum spacing is the floor, not the ceiling. A thousand feet is almost a fifth of a mile; in thick brush or rolling terrain, that gap can leave long stretches of boundary that feel unposted to anyone walking the line. Tighter spacing costs more at the start and is much harder to challenge later.

Document the posting. Photograph each sign, paint mark, or fence section with GPS data or alongside a GPS reading. If a case ends up in court, you need to show the property was properly posted on the date of the incident, not just that you remember putting signs up at some point. Walk the boundary at least once a year to refresh faded paint and replace damaged signs. Faded or missing markings are a common reason trespass complaints go nowhere.

For large mixed tracts, post the whole perimeter at the 100-foot forest-land standard when you are not certain where the forest line ends. Over-posting creates no legal problem. Under-posting does.
