In 2020, CUE stopped collecting fares to reduce passenger contact during the COVID-19 pandemic. In January 2022, the City Council approved a plan to formalize a 3-year zero-fare pilot program that would make CUE free to ride through June 2025. In the spring of 2022, CUE was awarded a Transit Ridership Incentive Program grant from the Virginia Department of Rail and Public Transportation, extending the pilot through June 2026.
By November 2025, the policy's fate was still being determined. While CUE steadily lost ridership for over a decade starting from 2008, the trend actually reversed due to the suspension of fare collection in 2020 - in spite of the pandemic, ridership actually started trending upward. During a presentation to City Council, James Gamez, a transit project manager of the consultant Kimley Horn, leading the evaluation on whether CUE should continue the zero-fare policy or resume fare collection, said: “This coming year, CUE is expected to exceed 1 million rides, and we’ve seen about a 60% increase from the pre-pandemic levels of ridership.”
After the grant expired, the city continued to fund fare-free CUE service in its annual budget; the buses remain free for all passengers as of August 2026[update].
CUE operates two loop routes between George Mason University and the Vienna Metro station, each running in both directions for a total of four named routes. The Green loop, consisting of routes Green 1 (clockwise) and Green 2 (counterclockwise) operates on the east side of Fairfax, while the Gold loop, consisting of routes Gold 1 (clockwise) and Gold 2 (counterclockwise) operates on the west side. Headways on each individual route are approximately 30–35 minutes on weekdays and 60–70 minutes on weekday evenings and weekends.
In addition to providing service to GMU and Vienna Metro, the CUE serves all major activity centers in the City of Fairfax, including downtown, Kamp Washington, Old Town Fairfax, Fairfax Circle and Fair City Mall.

As of May 2022[update], the CUE Bus fleet is entirely clean diesel fueled. The system operates twelve 35 foot (11 m) Gillig BRT buses. Half of these vehicles replaced the remaining Gillig Phantom vehicles in the fall of 2015, while the others entered service in May 2022 replacing the agency's hybrid buses.
