1. What is the primary purpose of surveillance in a private
investigation?
A. To confront the subject directly
B. To gather relevant facts through lawful observation
C. To obtain information by deception in every situation
D. To determine the subject’s guilt
Correct Answer: B. To gather relevant facts through lawful
observation
Rationale: Surveillance is primarily a fact-gathering activity. A
private investigator observes and documents relevant activities
while remaining within applicable laws and professional
boundaries. The investigator should avoid confrontation and
,should not assume that surveillance establishes criminal or civil
guilt.
2. Before beginning mobile surveillance, what should an
investigator do first?
A. Contact the subject
B. Review the assignment objectives and available information
C. Follow the subject immediately without preparation
D. Notify nearby businesses
Correct Answer: B. Review the assignment objectives and
available information
Rationale: Effective surveillance begins with preparation.
Reviewing the investigative objectives, known identifying
information, locations, schedules, vehicles, and relevant
instructions helps the investigator conduct surveillance efficiently
and reduces unnecessary risks.
3. Which characteristic is most important when selecting a
surveillance position?
A. Maximum visibility regardless of circumstances
B. Proximity to the subject at all times
C. A reasonable balance between observation and discretion
D. A location directly in front of the subject’s residence
Correct Answer: C. A reasonable balance between
observation and discretion
Rationale: A surveillance position should provide a useful
observation point without unnecessarily attracting attention.
,Investigators must consider visibility, safety, lawful access, traffic
conditions, and the possibility that remaining too close could
compromise the investigation.
4. During surveillance, an investigator should generally document
observations using:
A. Personal opinions and assumptions
B. Objective and factual descriptions
C. Unverified statements from strangers
D. Conclusions about the subject’s intentions
Correct Answer: B. Objective and factual descriptions

from interpretation. Recording what was actually seen, heard, or
otherwise lawfully documented makes the report more credible
and easier to evaluate later.
5. Which information is most useful for identifying a vehicle
during surveillance?
A. The investigator’s preferred vehicle color
B. Make, model, color, and license plate information when
lawfully observed
C. The investigator’s opinion of the driver
D. The estimated personality of the driver
Correct Answer: B. Make, model, color, and license plate
information when lawfully observed
Rationale: Specific identifying characteristics help prevent
confusion between vehicles. Investigators should record
, information accurately and avoid guessing when a detail cannot
be reliably observed.
6. What is a major disadvantage of following a subject too
closely?
A. It improves investigator safety
B. It makes documentation unnecessary
C. It increases the possibility of detection
D. It guarantees continuous observation
Correct Answer: C. It increases the possibility of detection
Rationale: Excessive proximity can make a surveillance vehicle or
investigator appear suspicious. Maintaining an appropriate
distance, adjusting position when conditions change, and
avoiding predictable behavior can help preserve discretion.
7. If a subject enters a private residence, the investigator should
generally:
A. Enter without permission to maintain surveillance
B. Break a window to continue observation
C. Remain within lawful boundaries and document what can
lawfully be observed
D. Pretend to be a police officer

trespass or unlawfully enter private property. Investigators must
