Rock Springs, Wyoming is an excellent place to launch a trucking business. With a population of 23K and ~2K businesses, Rock Springs offers a robust market. Trucking is a high-liability business where a single accident can result in millions of dollars in damages. An LLC separates your personal assets from your trucking business, so an accident claim does not put your home and personal savings at risk. An LLC is also often required to obtain your own DOT number and motor carrier authority.
