What are the three components of every CTA incident?

The correct answer identifies the three essential components of every CTA incident as the incident itself, the impact zone, and full service.

Understanding these components is crucial for effectively managing incidents. The incident refers to any event that disrupts the normal operation of the transit system, such as accidents or service failures. The impact zone denotes the area directly affected by the incident, highlighting where service interruptions or hazards may occur. Recognizing this zone helps transit staff efficiently direct resources and manage safety concerns.

Full service indicates that the system aims to restore operations to normal as quickly as possible after an incident. This term also emphasizes the importance of having plans in place to recover from disruptions, ensuring a reliable service for passengers.

The other choices, while including components related to incidents, do not fully represent the core aspects that are vital for understanding the complete management process of CTA incidents. For example, a recovery plan is critical to address incidents, but it operates as a response strategy rather than a fundamental component of the incident itself.
