What does the term "layover" refer to for CTA bus operators?

The term "layover" for CTA bus operators refers to a scheduled break or wait time between bus runs. This period is essential for bus operators, as it allows them to rest, manage their schedule, and prepare for the next trip. During a layover, the bus may remain at a terminal or designated stop, ensuring that buses are spaced appropriately for passengers. This waiting period is regulated by the transit authority to ensure that operators do not exceed their working hours while also maintaining a reliable service for riders.

The other options, while they may pertain to specific operational procedures, do not accurately capture the essence of what a layover represents in the context of bus operations. Fueling and cleaning activities are separate operational tasks that can occur but are not specific to the definition of a layover. Route change announcements are also unrelated, as they deal with communication between operators and management rather than downtime between service runs.
