What situation is indicated by the code 10-72?

The code 10-72 specifically refers to the situation where a Chicago Transit Authority vehicle has been involved in a collision with a person. This designation is essential for quick communication among transit personnel and responding units, ensuring that the nature of the incident is clearly understood and addressed promptly.

When this code is communicated, it alerts emergency services and other department staff that there may be a serious situation involving an injury to an individual caused by a CTA vehicle. This allows for an immediate and coordinated response to help the person involved and manage the incident more effectively.

The other options refer to different types of incidents: employee illness or other injuries that do not involve a vehicle collision, and fire, which has its own specific codes and procedures for response. Each code serves a particular purpose in ensuring clarity and efficiency in communication during emergencies.
