Knowing about purple paint laws can help you stay on the right path when driving or hiking in an unfamiliar place.

During the summer, a lot of people enjoy traveling, vacationing and outdoor adventures while the weather is warm and comfortable. If you’re somewhere new or unfamiliar, it’s always good to get a proper idea of your surroundings. Better safe than sorry, right?

The next time you’re out exploring with your friends and family, keep an eye out for purple fence posts.

What Does a Purple Fence Mean?
The laws vary from state to state, but generally, a purple fence means no trespassing. While property owners may still choose to use “No Trespassing” signs, the signs are likely to be stolen, damaged or worn out over time. A quick coat of purple paint has staying power, though.

It can be easily applied to different land markers, too. In addition to purple fence posts, you might even see purple trees! The color purple can also be distinguished by those who are color-blind.
