El Paso County, under Texas Transportation Code Chapter 458, services as a rural transit district (RTD) for rural El Paso County and therefore receives state funding for rural transit services. The RTD duties are performed through the El Paso Area Transportation Services, Local Government Corporation (EPATS, LGC) via an interlocal agreement. EPATS has branded the transit system as El Paso Transportation Authority (ETA). EPATS is a partnership between El Paso County, Horizon City, the City of San Elizario, the Village of Vinton, and the Towns of Anthony and Clint. The City of El Paso Mass Transit Department (known as Sun Metro) serves only the El Paso City limits as part of the El Paso Urbanized Area (UZA). The governing body of the RTD is the El Paso County Commissioners Court. The governing body of EPATS is the EPATS Board of Directors.

EPATS provides fixed-route, complementary ADA paratransit, and microtransit services that serve Anhtony, Canutillo, Vinton, and Westway in the northwest; Montana Vista in the east; Agua Dulce, Clint, Fabens, Horizon City, San Elizario, Socorro, Sparks, and Tornillo in the southeast; and other unincorporated areas of the county. These communities lie outside the city limits of El Paso; all except Fabens and Tornillo are part of the El Paso UZA. EPATS operates six fixed-routes, a complementary ADA paratransit service, a vanpool program and a pilot microtransit service via a contracted service provider.

Riders can access Amtrak rail service, Greyhound, El Paso−Los Angeles Limousine, Tornado Bus Company, and Autobuses Los Paisanos in downtown El Paso. In addition, El Paso County contracts with Enterprise to operate a vanpool program and partners with the New Mexico Department of Transportation to provide a park-and-ride service as a regional intercity bus route. All Aboard America is contracted to operate the park-and-ride route. The route connects Las Cruces, New Mexico, to downtown El Paso.
