STS routes

More than 30,000 riders ride the St. Mary’s Transit System each month. The system has about a dozen public transportation routes, including in Lexington Park, Leonardtown, Charlotte Hall, St. Mary’s City and other areas of the county.

Transit also plays a key role in the viability of the local economy and in the livability of neighborhoods. In addition, STS provides complimentary ADA Paratransit services for persons with disabilities and a Specialized Statewide Transportation Assistance Program for the elderly and persons with disabilities that are not sufficiently close to the main public transportation routes.

Customer service is important to the St. Mary’s County Department of Public Works and Transportation. The transit managers and rural community-based transit program accomplishes an essential mobility mission of the county, connecting people, communities, workplaces, educational institutions, recreational opportunities and many other essential destinations on a regular and continuous basis.

All passengers are required to be at the designated vehicle stop at the times listed. If no one is waiting at the location and no on-board passengers are exiting, the vehicle will not stop, but will continue to the next stop location. Buses will stop to discharge or pick up passengers at locations along any regular route (flag stops), if traffic and road conditions permit the safe operation of buses. Passengers wishing to board a vehicle at a location along the route between identified stops should “flag” the vehicle by signaling to the driver (hand waving is acceptable). The driver will stop as close to the passenger as possible as long as stopping is not a safety hazard.

To preschedule “pickup” or “stop requests,” call 301-863-8400, ext. 1120, Monday to Saturday between 5:30 a.m. and 8:30 p.m. When the offices are closed, arrangements can be made by leaving name, bus route and telephone number after the prerecorded message. Otherwise, arrangements can be made with the individual drivers upon boarding the bus.

Be at a safe location (typically 50 feet before an intersection/street corner) along the route. Be on the appropriate side of the street (such as northbound, southbound, etc.) Be clear in flagging the driver. Determine the approximate vehicle arrival time at the flag location (based on times identified on the schedule for designated stops surrounding the flag location) and arrive early. If able, call STS ahead of time so the driver can be notified. This will decrease chances of being missed or not seen by the driver.

Transferring from one route to another may occur at the following specified transfer locations — the governmental center complex in Leonardtown, the Tulagi Place Park & Ride lot in Lexington Park, and the Charlotte Hall Square. A single transfer fee is used for an uninterrupted ride across all of the routes. Transfers will not be accepted for interrupted trips at locations other than these transfer points; riders will be required to pay a new fee. Bus schedules for STS and VanGo (Charles County) are available from the bus drivers. Each county’s bus tickets will be honored by the other county to avoid extra costs to passengers.

For the safety of drivers and passengers, the bus drivers are not allowed to provide change. Therefore, all passengers must have exact fare or an STS ticket when boarding STS buses. Each bus driver reserves the right to refuse transportation to any passenger/rider who does not pay the required fare or who does not honor the bus rider’s agreement.

If an item is lost on an STS bus, call the STS office at 301-863-8400, ext. 1120 or 1121, between 8 a.m. and 5 p.m. Although STS is not responsible for lost items, all found items will be held at the STS office for a period of up to 30 days. If STS can verify that the item is the property of the passenger, the item will be returned.

In June 2013 the Maryland Transit Administration approved a five-year transportation development plan to improve public transportation service in St. Mary’s County, and the agency is committed to ensuring that no person is excluded from participation or denied the benefits of the transit services offered. If a person feels he or she has been discriminated against by the STS transportation division, complete the non-discrimination public notice available on the agency’s website and submit the form to Mary Ann Blankenship at

The STS office is staffed Monday through Saturday, 5:30 a.m. to 8:30 p.m. Customers who are not familiar with STS services may call for assistance at 301-863-8400, ext. 1120 or 1121. A dispatcher will explain bus routes needed to reach a destination, advise of any needed transfers, help determine the time that the bus will arrive at the stop and help determine exact fares.
