LA 10 serves as the principal east–west route for many of the small towns and cities it traverses. Roughly half of the route is classified by the Louisiana Department of Transportation and Development (La DOTD) as a rural minor arterial. Portions of the route running through sparsely populated areas or areas otherwise served by the interstate highway system are often classified as major collectors. The very lightly populated and travelled section immediately east of the Atchafalaya River is a minor collector. However, several brief stretches of LA 10 serve as principal arterials, such as the portion running through Bogalusa and the concurrencies with US 61 and US 167 through St. Francisville and Ville Platte, respectively.
