Ride-On

 is the primary public transportation system in Montgomery County, Maryland. Ride On serves Montgomery County as well as the community of Langley Park in Prince George's County. Ride On also serves the Takoma Metro station, and Sibley Memorial Hospital in Washington, D.C.

Ride On operates 80 routes, including operating three Metrobus routes on weekends.

In 2009, Ride On introduced a new logo and blue-yellow-green paint scheme with the delivery of new Gillig Low Floor clean diesel and hybrid buses.

In the autumn of 2011, Ride On's 12 new 40-foot Gillig low-floor hybrid buses (5349-5360) and one clean diesel bus (5758) went into service. All 13 of these buses were purchased with funds from the American Reinvestment and Recovery Act. Ride On is currently in the process of taking delivery of the new 2012 40' Gillig Low Floor hybrid buses, which were also purchased with stimulus funds from the ARRA.

In July 2012, Ride On retired all 62 of its 2007 Champion cutaway buses due to fires and replaced them with 30 1998 30-foot Orion V buses. All 30 of these units were from Metrobus.
