Most local routes operate seven days a week with 20-minute or 30-minute service patterns during weekdays. Saturday service operates within 30- to 60-minute headways and Sunday service operates within 45- to 90-minute headways.

On June 17, 2019, GMT converted all the previously-numbered routes to colored through-routed (via the DTC) services. A short time thereafter, due to passenger feedback, GMT added the route numbers back in with the color scheme. The Red Line was composed of the 7 and 1 routes, the Blue Line with the 6 and 2, the Green Line with the 5 and 9 and the Orange Line with the 10 (and the later addition of the 4, which was originally the Silver Loop after conversion). The 8 became the Gold Loop. On June 14, 2021, due to more customer feedback, the GMT eliminated the color designations in favor of the previous numerical ones.
The following routes are now operated by RCT as of January 1, 2026:
As of May 20, 2024, the fare is $2.00, with a $4.00 daily cap, and a $50.00 monthly cap. Discounted fares for people under 17, over 60, or who are disabled are $1.00, with a $2.00 daily cap and a $25.00 monthly cap. Fares can be paid using the Ride Ready app, a smart card, contactless payment, or cash. However, the fare cap only applies when using the Ride Ready app. Fares do not apply on rural services.
Most of the GMT fleet is made up of Gillig low-floor transit buses, although a number of New Flyer and Proterra buses are used. MCI long-distance buses and various shuttle buses built on Ford E-350 chassis have been purchased for intercity routes and transit service in outlying towns, respectively.<br />Note that this list is incomplete.
GMT's Downtown Transit Center is located in downtown Burlington on Saint Paul Street, between Pearl and Cherry Streets, with adjoining space along Pearl Street. The commuter and express routes (86, 96) generally operate from adjacent bus stops located on Pearl Street. GMT also has a transit center in Montpelier.
