Bus service is efficient and inexpensive. Public buses are blue with a yellow stripe; yellow buses with a blue stripe are privately owned and operated; and "ZR" vans (so called for their ZR license plate designation) are white with a maroon stripe and also privately owned and operated. All buses travel frequently along Highway 1 (St. James Road) and Highway 7 (South Coast Main Road), as well as inland routes. The fare is Bds$2 for any one destination; exact change in either local or U.S. currency ($1) is appreciated. Buses run about every 20 minutes. Small signs on roadside poles that say "To City" or "Out of City," meaning the direction relative to Bridgetown, mark the bus stops. Flag down the bus with your hand, even if you're standing at the stop. Bridgetown terminals are at Fairchild Street for buses to the south and east and at Lower Green for buses to Speightstown via the west coast.
