In Nevada, no law makes it a crime just to be drunk in public. But there are all kinds of ways that being drunk in public can get you in trouble with the law. For example, it’s illegal to create a public disturbance. Breach of the peace and creating a public disturbance are laws that are relatively vague, so they fit a wide range of behaviors.
It’s also illegal to disrupt the flow of traffic as a pedestrian. Nevada law 484B.283 makes it unlawful for a person on foot to leave the curb and enter traffic in a way that a driver can’t yield to avoid them. Pedestrians can lawfully use crosswalks and other traffic control devices that are made for pedestrians. But if you’re a pedestrian and you jump in front of moving traffic, you may find yourself the recipient of a traffic ticket at the very least.
