RTC Transit is the name of the bus system in the Las Vegas metropolitan area of Clark County, Nevada. It is a subsidiary of the Regional Transportation Commission of Southern Nevada. While it services most of Clark County with regularly scheduled routes, most of the service is in the immediate Las Vegas Valley; outlying places such as Mesquite and Laughlin provide transit services to their residents via the Southern Nevada Transit Coalition, which uses several vehicles acquired from RTC Transit. In 2021, the system had a ridership of 39,366,700, or about 134,200 per weekday as of the second quarter of 2022.
