[3] City of Santa Clarita Transit routes connect with services operated by Metro and Metrolink.

The Los Angeles County Department of Public Works contracts with City of Santa Clarita Transit to provide fixed route and Dial-A-Ride services in some unincorporated areas of Los Angeles County that are near the city limits of Santa Clarita.

These areas include the communities of Castaic, Forest Park, Stevenson Ranch, Sunset Pointe, and Val Verde.

[4] In mid-2007 Santa Clarita Transit entered into a contract with MV Transportation and underwent a branding overhaul.

The program's purpose is threefold, bus stops will become more uniform in look and features, the advertisement on benches will be eliminated, and public art will have a large expansion.

The beach bus is identified by route number, 103, only in operation from June to Labor Day in September, only on Saturdays and Sundays.

[7] On September 15, 2023, after over a year of negotiations with MV Transportation, transit service workers represented by Teamsters Local 572 voted to go on strike until a fair contract is reached.

[8] The strike officially began on October 9, halting all bus and paratransit services across the city.

Station Link service operates on weekdays peak periods (6-9am, 4-6pm) only except route 501, which as of February 2023, makes morning and afternoon trips excluding midday even on Saturdays and Sundays, select holidays included.
