Patrol and Traffic Operations Flashcards

During a traffic stop at night, what is the recommended officer safety position when approaching a vehicle on the driver's side?

Answer: Position slightly to the rear of the B-pillar to avoid being in front of the door

Standing slightly to the rear of the B-pillar keeps the officer out of the immediate line of fire if the door opens or a weapon is presented.

Under Virginia Code, when must a law enforcement officer activate emergency lights and siren to legally exceed posted speed limits?

Answer: Both emergency lights and siren must be activated simultaneously

Virginia law requires both audible warning device (siren) and visual signal (emergency lights) to be activated when exceeding speed limits in an emergency response.

A driver you have stopped for speeding produces a suspended license. What is the FIRST action you should take?

Answer: Run a records check to confirm the suspension status before taking enforcement action

Officers must verify suspension status through NCIC/DMV records before taking enforcement action, since database errors can occur.

Which patrol method is most effective for reducing response time while maximizing area coverage in a large patrol zone?

Answer: Random preventive patrol distributed throughout the zone

Random preventive patrol throughout the zone distributes officer presence and minimizes predictability while maintaining broad coverage.

When conducting a felony traffic stop, where should the officer's patrol vehicle be positioned relative to the suspect vehicle?

Answer: At an angle offset to the left, approximately one car length behind, using the engine block as cover

An angled position one car length behind uses the engine block for ballistic cover while allowing the officer to observe and communicate with the suspect.

A motorist is involved in a minor crash on a Virginia highway with no injuries. Under Virginia Code § 46.2-894, what are they required to do?

Answer: Move the vehicle out of the travel lane if it can be safely operated and is blocking traffic

Virginia's 'move it or lose it' law requires drivers to move operable vehicles involved in minor crashes out of the travel lane to improve safety and traffic flow.

During patrol, an officer observes a vehicle with a broken tail light at 2 a.m. in a high-drug-activity area. This observation alone provides the officer with:

Answer: Reasonable suspicion to conduct a traffic stop for a equipment violation

A broken tail light is a traffic equipment violation that provides reasonable suspicion (and probable cause for the infraction) to initiate a lawful traffic stop.

Under the 'plain view' doctrine during a traffic stop, an officer may seize contraband without a warrant when:

Answer: The officer entered the vehicle lawfully and the item's incriminating nature is immediately apparent

Plain view allows warrantless seizure when the officer is lawfully present, the item is in plain view, and its incriminating character is immediately apparent.

When writing a crash report in Virginia, the term 'contributing circumstance' refers to:

Answer: A factor related to the road, environment, or vehicle that contributed to the crash

Contributing circumstances on Virginia crash reports include road conditions, environmental factors, and vehicle defects separate from driver behavior.

An officer on patrol receives a call about a suspicious person matching the description of a wanted subject. To conduct a valid Terry stop, the officer must have:

Answer: Reasonable articulable suspicion based on specific facts that criminal activity is afoot

Terry v. Ohio established that a brief investigative stop requires only reasonable articulable suspicion, not full probable cause.

What does the acronym BOLO stand for in law enforcement patrol communications?

Answer: Be On the Lookout

BOLO — 'Be On the Lookout' — is a broadcast to patrol units describing a suspect, vehicle, or item officers should watch for.

A driver stopped for a traffic infraction refuses to provide their driver's license. Under Virginia Code § 46.2-104, the officer may:

Answer: Arrest the driver for failing to present their license on demand

Virginia Code § 46.2-104 requires drivers to present their license on demand to an officer, and refusal is a misdemeanor supporting a custodial arrest.

During a traffic stop, the officer smells fresh marijuana coming from a vehicle. Under current Virginia law (post-2021 legalization), this odor alone:

Answer: May be one factor considered in the totality of circumstances but is not automatic probable cause alone

Following Virginia's marijuana legalization, courts have ruled that marijuana odor alone is no longer automatic probable cause and must be considered among other totality-of-circumstances factors.

An officer is pursuing a fleeing vehicle at high speed through a residential area. The DCJS-recommended primary factor for deciding to terminate pursuit is:

Answer: Whether the risk to the public outweighs the need to apprehend

DCJS and Virginia model pursuit policies require officers to continuously balance the need to apprehend against the risk posed to officers, the public, and third parties.

When an officer directs traffic manually at an intersection where signals have failed, which hand signal means 'stop' to approaching traffic from the front and rear?

Answer: Arm extended horizontally with palm facing approaching traffic

The standard stop signal is an arm extended horizontally toward the traffic being stopped, with the palm facing that traffic.

Which of the following actions constitutes an unlawful pretextual stop under Virginia's updated case law guidance?

Answer: Using a minor infraction as justification when the sole motivation is to investigate for unrelated criminal activity based on the driver's appearance

While Whren v. United States permitted pretextual stops federally, Virginia law and department policies increasingly scrutinize stops where the real motivation is unrelated to the stated infraction.

What is the legal standard required before an officer may conduct a pat-down (frisk) of a person during a Terry stop?

Answer: Reasonable belief that the person is armed and dangerous

Terry v. Ohio limits a pat-down to situations where the officer has specific, articulable facts creating a reasonable belief the person is armed and dangerous.

Under Virginia Code, the speed limit in a school zone when children are present is:

Answer: 20 mph

Virginia Code § 46.2-873 establishes a 20 mph speed limit in school zones when indicated by posted signs and children are present.

When completing a field sobriety test (FST), which three tests are recognized as standardized by NHTSA?

Answer: Horizontal Gaze Nystagmus, Walk and Turn, and One Leg Stand

NHTSA validates only the Horizontal Gaze Nystagmus (HGN), Walk and Turn, and One Leg Stand as standardized field sobriety tests with established reliability data.

An officer responding to a domestic disturbance call should park the patrol vehicle:

Answer: One or two houses away to avoid alerting the subject and allow tactical assessment

Parking nearby but not directly in front reduces the risk of alerting a potentially armed subject while still allowing quick access to the scene.
