STAR Transit primarily connects non-DART member cities to the light rail system in Dallas with fixed bus routes and on-demand service.

[1][6] However, KART would soon need to expand its focus as cities in Dallas County who had originally rejected to join DART in the 1980s realized the system's benefits; Mesquite agreed to pay over $300,000 a year for DART to establish a new bus route that connected the city's Hanby Stadium to the Green Line through Lawnview station.

[8] The MTX 101 Route starts at Walmart and ends at Peachtree Senior Living Apartments, providing access to Floyd Elementary School, Balch Springs Recreation Center, and other destinations with a total of ten stops.

[9][10] The COMPASS Shuttle travels directly from DART Green Line Lawnview station to Hanby Stadium near downtown Mesquite on weekdays only.

[11] The 401 Shuttle operates in a loop, providing service to DART Blue Line UNT Dallas station, Cedar Valley College, and various apartments and stores via 11 stops.

[10][12] STAR Transit has suspended various fixed routes, mostly due to low ridership or high cost reasonings: STAR Transit provides on-demand service in Mesquite, Balch Springs, Kaufman, Terrell, Forney, Seagoville, and DeSoto via the associated STARNow app or phone number.
