It was formerly known as Dixie Area Rapid Transit or DART, which was launched and funded by Five County Association of Governments in 2003.

The City of St. George in conjunction with federal transportation funding bought the bus system, today known as SunTran.

SunTran may eventually expand into a metro/county-wide mass transit system as local municipalities secure efficient funding.

In accordance with the Utah Clean Air Act, SunTran and the City of St. George, smoking is prohibited on all buses and within 25 feet (7.6 m) of a bus stop.

SunTran currently operates seven fixed routes with nearly 200 bus stops serving St. George, Ivins, and Washington within the metropolitan area.
