RTC Transit is a public transit system in the Las Vegas metropolitan area in the US state of 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 communities such as Mesquite and Laughlin provide transit services to their residents via the separate Silver Rider Transit system, which uses several vehicles acquired from RTC Transit. In 2025, the system had a ridership of 57,888,500, or about 172,800 per weekday as of the first quarter of 2026.
