St. Mary's Transit System (STS)

The St. Mary's Transit System (STS) connects our community to essential destinations, workplaces, and recreational opportunities. We provide reliable, accessible public transportation across the county, including specialized ADA Paratransit services to ensure mobility and independence for all residents.

In addition, STS provides complimentary ADA Paratransit services for persons with disabilities and a Specialized Statewide Transportation Assistance Program (SSTAP) for the elderly and persons with disabilities that are not sufficiently close to the main public transportation routes. In December 2019 the Maryland Transit Administration (MTA) approved a 5-year Transportation Development Plan (PDF) (TDP) to improve public transportation service in St. Mary's County and we are committed to ensuring that no person is excluded from participation or denied the benefits of the transit services we offer. If you feel you have been discriminated by the STS - Transportation Division please complete the Non Discriminatory Policy (PDF) and submit the Form to STS Dispatchers.
