A caller provides an address that does not appear in the CAD system. What is the BEST first step for the dispatcher?
Answer: Ask the caller for nearby landmarks, cross streets, or a neighboring address
When an address is not found in CAD, gathering nearby landmarks or cross streets allows the dispatcher to approximate and confirm the location.
Which cardinal direction does a street running left-to-right typically represent on a standard North-up map?
Answer: East–West
On a North-up map, horizontal (left-to-right) streets run East–West, while vertical streets run North–South.
What does 'CAD mapping' primarily help a 911 dispatcher do?
Answer: Visually confirm caller location and identify nearby units and resources
CAD mapping displays caller locations, unit positions, and available resources on a real-time map to support dispatch decisions.
A caller reports an emergency at a rural address on County Road 450 North. What characteristic of rural addressing should the dispatcher be aware of?
Answer: Rural addresses often reflect distance from a baseline in feet or tenths of miles
Many rural counties use a grid-based system where address numbers correspond to feet or fractions of miles from a county baseline.
Which term describes the physical area assigned to a specific fire station or police precinct for primary response?
Answer: First-due district
A 'first-due district' defines the geographic area where a specific unit is expected to respond first to any incident.
A caller describes being at a 'T-intersection.' What does this tell the dispatcher about the road layout?
Answer: Three roads meet at one point, forming a T shape
A T-intersection is where one road ends at another, creating a T shape with three arms instead of a full four-way crossing.
When a caller mentions their location is near the 'city limits,' what should a dispatcher consider?
Answer: Jurisdiction may transfer to a neighboring agency, requiring coordination
Calls near city limits may fall under a neighboring jurisdiction, requiring the dispatcher to coordinate with or transfer the call to the appropriate agency.
