No Trespassing Sign Laws in Arkansas: Posting, Paint, and Penalties

Under Arkansas’s no trespassing sign laws, you can legally post your land with signs, light-purple paint marks, or a sufficient fence, but the spacing depends on the land type: markings must appear every 100 feet on forest land and can stretch to every 1,000 feet on other property, with a marking at every point of entry either way.¹²

Forest Land Versus Other Property

Arkansas keeps two separate posting statutes, and picking the wrong one is the mistake that most often undoes a landowner’s efforts. Forest tracts fall under a stricter spacing rule; cultivated land, pastures, orchards, and other non-forest property fall under a more relaxed one.¹

Every other specification, from the words on the sign to the size of the paint mark, is identical between the two statutes. The difference is spacing alone. A forest tract posted at 1,000-foot intervals does not meet the legal standard, and if your land contains both forest and non-forest sections, each section has to be posted to its own rule.

Posting With Signs

Signs must display the word “posted” or “no trespassing” (or both) in letters at least four inches high, and they must be placed so anyone approaching the property can readily see them.²

On non-forest property, signs go around the boundary at intervals of no more than 1,000 feet and at every point of entry. On forest land, that interval tightens to 100 feet.¹ A point of entry is any road, trail, gate, or gap where a person could reasonably walk onto your land, and missing even one gives a trespasser an argument that they had no notice.

The statute doesn’t dictate sign material, color, or size beyond the four-inch letter height. Durable metal or heavy plastic outlasts cardboard or paper in Arkansas weather, and a sign that has faded past legibility or fallen off its post counts as no sign at all when enforcement time comes.

Purple Paint Markings

Arkansas lets you post land with paint instead of signs. The paint must be light purple and exterior grade.³ Purple was chosen because the timber industry does not use it for boundary or land-line marks, so a purple slash cannot be mistaken for a logger’s work.²

Each mark must be a vertical line at least eight inches long, placed between three and five feet above the ground, and readily visible to anyone approaching. On non-forest property, marks go on posts spaced no more than 1,000 feet apart and at every entry point. On forest land, they go on trees or posts no more than 100 feet apart and at every entry point.¹

Paint has real advantages in wooded and rural areas. Signs get stolen, shot up, or blown down, and replacing them on a large tract is expensive. A painted tree stays put. The tradeoff is that not everyone recognizes purple paint as a legal warning, especially out-of-state visitors, so some owners use both paint along the boundary and signs at major access points.

Fencing as a Posting Method

Both statutes recognize fencing as a third option. The fence must be “sufficient” under Arkansas’s general fencing laws, which were originally written for livestock containment.² There is no prescribed height, material, or style specific to trespass posting.

In practice, a fence that clearly marks the boundary and would deter a reasonable person from crossing works. Barbed wire, woven wire, and board fencing all qualify. A decorative two-rail fence with wide gaps is harder to defend. Fencing also produces strong evidence in court, because cutting or removing a posted fence is itself a criminal offense.

Penalties for Trespassing on Posted Property

Criminal trespass in Arkansas means purposely entering or remaining on someone else’s property without authorization. The base offense is a Class C misdemeanor, and the classification climbs with the circumstances.⁴

Class C misdemeanor — 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, and any trespass by someone with a prior conviction.
Class D felony — trespassing on critical infrastructure, or a third or subsequent conviction after two Class A misdemeanor trespass convictions.

The sign-removal rule is worth noting for landowners. If someone tears down your no-trespassing sign or cuts through your posted fence, that single act pushes the offense from a Class C to a Class B misdemeanor.⁴

Who Can Still Enter Posted Land

Posting does not keep everyone off your land. Arkansas exempts several categories of people from criminal trespass when they are acting within the scope of their duties, and it recognizes defenses that can defeat a charge even against ordinary visitors.⁴

The following people can enter posted property without your permission when performing their official work:

Law enforcement officers on official duty.
Firefighters and emergency first responders, including EMTs and paramedics, responding to an emergency.
State, federal, and local government employees whose visit directly relates to their job, such as code inspectors and child welfare workers.

Several other situations serve as defenses if a trespass charge is filed:

The person was a guest or invitee, even informally.
The person entered for a legitimate business purpose or to address a health or safety concern.
The property was generally open to the public.
The person is an adjoining landowner or their employee crossing in good faith for a legitimate reason.
The person entered solely to recover livestock, a dog, or another domesticated animal.

None of this authorizes damage or activity beyond the reason for entry. An inspector can walk your land for an inspection, not for a personal ramble.

Misuse of the Posting System

Using the designated purple paint on trees or posts for anything other than posting your own land is a Class B misdemeanor. Posting property you do not own or lease, without written permission from the owner, is also a Class B misdemeanor.⁵

Making Your Posting Hold Up

The statutory minimums are the floor. On non-forest land, 1,000-foot spacing means someone can walk nearly a fifth of a mile between signs, and in thick brush or rolling terrain that gap leaves long stretches effectively unmarked. Posting closer together costs more upfront and is much harder to challenge later.

Document what you put up. Photograph each sign, paint mark, and fence run with GPS-tagged images or alongside a GPS reading. If a dispute reaches court, you need to show the property was properly posted on the day of the incident, not just that you remember putting signs out at some point. Refresh paint and replace damaged signs at least once a year, because faded or missing markings are a common reason trespass complaints go nowhere.

For a large tract that mixes forest and non-forest ground, and especially where you aren’t sure exactly where one type ends and the other begins, post the whole perimeter at the stricter 100-foot forest-land interval. Over-posting is never a legal problem. Under-posting is.
