If you encounter a purple fence post, it’s wise to steer clear.
A purple fence post is a clear signal to anyone nearby: No trespassing!
While property owners can put up signs to mark private property, signs can fade or wear out, whereas paint endures much longer and still delivers the same warning.
In 1987, Arkansas became the first state to enact a purple paint law. Today, 22 states allow landowners to mark the boundaries of their property with purple paint.
While some states, like Idaho and Montana, use orange paint instead, the purpose remains the same.
Initially, many states required landowners to use both purple paint and signs, but over time, the need for signage was phased out. However, if you live in one of the 28 states without a purple paint law, you might be unaware of its significance.
A painted post or tree simply means no trespassing.
To comply with the law, the purple stripe must be positioned 3 to 5 feet off the ground and measure at least 8 inches in length and 1 inch in width. The markings should be spaced no more than 100 feet apart.
