911 Operator Test Geographic Knowledge and Map Reading 3 — Questions and Answers
Question 1: A caller provides an address that does not appear in the CAD system. What is the BEST first step for the dispatcher?
- Decline the call until the address is verified
- Ask the caller for nearby landmarks, cross streets, or a neighboring address (Correct answer)
- Automatically dispatch to the closest known address
- Transfer the call to a mapping specialist
Correct 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.
Question 2: Which cardinal direction does a street running left-to-right typically represent on a standard North-up map?
- North–South
- East–West (Correct answer)
- Northeast–Southwest
- It depends on the scale
Correct answer: East–West
On a North-up map, horizontal (left-to-right) streets run East–West, while vertical streets run North–South.
Question 3: What does 'CAD mapping' primarily help a 911 dispatcher do?
- Record call audio for legal purposes
- Visually confirm caller location and identify nearby units and resources (Correct answer)
- Calculate the salary of dispatched officers
- Generate automated court documents
Correct 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.
Question 4: 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?
- Rural addresses always end in 'RD' abbreviation
- Rural addresses often reflect distance from a baseline in feet or tenths of miles (Correct answer)
- Rural addresses are not recognized in CAD systems
- County roads always run parallel to interstate highways
Correct 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.
Question 5: Which term describes the physical area assigned to a specific fire station or police precinct for primary response?
- Response grid
- Primary jurisdiction
- First-due district (Correct answer)
- Mutual aid zone
Correct answer: First-due district
A 'first-due district' defines the geographic area where a specific unit is expected to respond first to any incident.
Question 6: A caller describes being at a 'T-intersection.' What does this tell the dispatcher about the road layout?
- Three roads meet at one point, forming a T shape (Correct answer)
- The intersection has a traffic light shaped like a T
- Two streets cross at 90-degree angles with a tunnel below
- The road ends at a river or barrier
Correct 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.
Question 7: When a caller mentions their location is near the 'city limits,' what should a dispatcher consider?
- The call should be routed to the state police automatically
- Jurisdiction may transfer to a neighboring agency, requiring coordination (Correct answer)
- City limits always fall on major highways
- The CAD system will automatically reassign the call
Correct 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.
A caller provides an address that does not appear in the CAD system.
