History
Metrobus was founded on February 4, 1973, after acquiring DC Transit, Washington, Virginia and Maryland Coach Company (WV&M), Alexandria, Barcroft and Washington Transit Company (AB&W) and the Washington Marlboro and Annapolis Motor Lines (WM&A) to combine into Metrobus. During its founding, WMATA dropped transfer charges, extended senior citizen discounts region-wide and began fare reductions on routes formerly served by the different carriers at different rates. WMATA also unified a new bus livery with red, white and blue paint scheme and purchased 620 buses from AM General with the last buses being delivered in 1974. Today, Metrobus serves the nation's capital 24/7, with over 1,500 buses.

, the Metrobus fare structure is as follows for cash and SmarTrip:

Discounts are available for senior citizens, people with disabilities and D.C. students.

Up to two children, per paying adult, under 5 years of age ride for free. Children at least 5 years of age pay adult fare.

All Metrobuses have SmarTrip card readers which automatically deduct the correct fare from a rider's SmarTrip card (including transfer credit).

Metrobus issued paper transfers until January 4, 2009. Transfers are now currently attainable only through SmarTrip cards.

On June 27, 2010, the transfer window was reduced from 3 hours to 2 hours.

All fares were free from mid-March 2020 to January 3, 2021, due to the COVID-19 pandemic. On December 6, 2022, the Council of the District of Columbia voted to abolish fares within city limits from July 1, 2023.

Fleet
On July 4, 2018, WMATA awarded a 5-year contract to New Flyer for up to 694 buses, order consist of forty-foot CNG, forty-foot clean diesel, sixty-foot CNG, and sixty-foot diesel heavy-duty transit buses. These new buses will replace Metro's older New Flyer Low Floor buses, which were delivered between 2005 and 2007. Red/Silver painted buses will be used on local routes and Blue/Silver buses will be used on limited stop routes. These buses will have either Local or MetroExtra on the top of each side of the bus for easy identification.

In 2020, WMATA received $4.1 million in funding from the Federal Transit Administration for the purchase of electric buses and charging infrastructure. A Sierra Club report indicated that a pilot study with 14 electric buses was planned, and estimated that 50% electrification would reduce the WMATA fleet's greenhouse gas (GHG) emissions by more than 58,000 tons of carbon dioxide per year.
