Which description matches code 443?

• A. Officer needs help emergency
• B. Airplane emergency
• C. Assist an officer (other jurisdiction/agency)
• D. Panic alarm at metro facilities

Answer: (C)

Code 443 is about requesting or providing assistance from outside your own agency or jurisdiction. It covers situations where an officer or unit needs help from another agency—whether another city, county, or state agency—or when you’re dispatched to assist an officer in a different jurisdiction. The idea is mutual aid across boundaries to handle incidents that exceed what one agency can manage alone, such as a pursuit or incident extending beyond city lines or requiring resources only available from another agency.

The other descriptions don’t fit this cross-jurisdictional support concept. An emergency call for officer help within the same jurisdiction is a more general emergency response. An airplane emergency involves aviation-specific procedures. A panic alarm at metro facilities relates to security alarms at transit sites.
