State Trooper Patrol and Investigation Procedures 3 — Questions and Answers
Question 1: A trooper finds a suspicious package on the highway. What is the correct initial response?
- Open the package to identify its contents
- Isolate, deny access, and notify a bomb disposal unit (Correct answer)
- Move the package to a safer location off the roadway
- Photograph the package and continue patrol
Correct answer: Isolate, deny access, and notify a bomb disposal unit
The recommended response to suspicious packages is to isolate the area, deny access to bystanders, and notify specialized units rather than handling the package.
Question 2: During a vehicle stop, a trooper smells the odor of marijuana. Under what legal standard may the trooper search the vehicle?
- Reasonable suspicion only
- Probable cause (Correct answer)
- A search warrant must be obtained first
- Consent of the driver is required
Correct answer: Probable cause
The odor of marijuana alone can establish probable cause to search a vehicle without a warrant in many jurisdictions.
Question 3: What is the purpose of a 'perimeter' established around a crime scene?
- To keep media at a distance for interviews
- To contain suspects still at the scene
- To protect physical evidence from contamination and control access (Correct answer)
- To designate staging areas for command staff
Correct answer: To protect physical evidence from contamination and control access
A crime scene perimeter preserves the integrity of physical evidence by preventing unauthorized access and contamination.
Question 4: When conducting a pat-down (Terry frisk) of a detained individual, what is the legal justification?
- Arrest of the individual
- Reasonable suspicion the person is armed and dangerous (Correct answer)
- Probable cause of any criminal activity
- Consent of the person being searched
Correct answer: Reasonable suspicion the person is armed and dangerous
A Terry frisk is limited to a pat-down for weapons when an officer has reasonable suspicion the detained person is armed and dangerous.
Question 5: A trooper responding to a domestic disturbance should make which assessment upon arrival?
- Immediately separate and arrest both parties
- Stage until backup arrives before any assessment
- Observe and assess for signs of ongoing violence or weapons before entry (Correct answer)
- Knock loudly and announce to de-escalate the situation
Correct answer: Observe and assess for signs of ongoing violence or weapons before entry
Observing the scene before entry allows the trooper to identify active threats and plan the safest approach.
Question 6: Which of the following best describes the chain of custody in an investigation?
- The hierarchy of command at a crime scene
- The documented record of who collected, handled, and stored evidence (Correct answer)
- The sequence in which witnesses are interviewed
- The order in which crime scene photos are taken
Correct answer: The documented record of who collected, handled, and stored evidence
Chain of custody is the chronological documentation ensuring evidence has been properly collected, handled, and stored, preserving its admissibility in court.
Question 7: A trooper observes a driver commit a minor traffic violation but suspects the driver may be DUI. The trooper should:
- Issue a written warning and let the driver proceed
- Stop the vehicle only if a second violation occurs
- Conduct a traffic stop based on the observed violation (Correct answer)
- Follow the vehicle for at least one mile before stopping
Correct answer: Conduct a traffic stop based on the observed violation
A single observed traffic violation provides sufficient legal justification for a traffic stop, and the stop can then reveal additional evidence of impairment.
