Which of the following is NOT a safety feature implemented on CTA buses?

The correct answer indicates that on-board security personnel is not a standard safety feature implemented on CTA buses. While CTA prioritizes safety through various means, on-board security personnel are not a routine presence on the buses. Instead, the CTA utilizes other methods to ensure the safety and security of passengers, such as surveillance and monitoring.

Security cameras are prominent features on CTA buses, as they help deter crime and provide valuable evidence in case of incidents. Emergency exit doors are also essential safety features, enabling quick evacuation during emergencies. Monitored GPS tracking enhances safety by enabling real-time tracking of buses, improving response time and coordination in emergencies. Each of these features plays a critical role in maintaining a safe transit environment, whereas the presence of security personnel is not consistently provided across the system.
