Reaction distance formula

Reaction distance equals speed multiplied by perception-reaction time. At 60 mph (88 feet per second) and a 1.5-second reaction time, the vehicle travels about 132 feet before braking begins.

Three E's of traffic safety

Engineering, education, and enforcement. Patrol officers contribute mainly through enforcement and visible presence, which deter violations and reduce crash frequency on assigned routes.

Crash scene priorities

First render aid and request EMS, then protect the scene, identify and separate witnesses, photograph and diagram, and finally clear the roadway as soon as evidence is recorded.

Terry stop standard

Reasonable suspicion of criminal activity permits a brief investigative detention and a pat-down for weapons. Probable cause is required for a full arrest and broader search.

Miranda trigger

Custodial interrogation requires warnings about the right to remain silent, that statements can be used, and the right to counsel. Once invoked, questioning must stop.

Exclusionary rule

Evidence obtained through an unconstitutional search or seizure is generally inadmissible at trial. Exceptions include inevitable discovery, attenuation, and good-faith reliance on a warrant.

Elements of a crime

Actus reus, mens rea, concurrence of act and intent, causation, and resulting harm. The prosecution must prove every element beyond a reasonable doubt.

Chain of custody

A documented record of every transfer of evidence, showing date, time, person, and purpose. Gaps allow defense challenges to authenticity and can render evidence inadmissible.

Active voice in reports

The subject performs the action: 'I observed the driver drop a bag.' Active voice identifies who did what and is preferred over passive constructions in police narratives.

Fact versus conclusion

Facts are observable and specific, such as slurred speech and an odor of alcohol. Conclusions are inferences, such as intoxication, and must be supported by stated facts.

Supplemental report

A dated follow-up report used to add or correct information after the original is complete. Original reports are never altered; corrections appear only in supplements.

Main idea

The controlling point a passage supports. It is often stated in the first or last sentence of a paragraph and is broader than any single supporting detail.

Valid inference

A conclusion required by the text but not stated directly. Correct answers stay within the passage; choices that add outside assumptions are wrong.

Extreme-word trap

Answer choices using always, never, all, or only usually overstate the passage. Correct answers match the passage's actual degree of certainty.

Vocabulary in context

Word meaning as used in the passage, not the most common dictionary sense. Substitute each option into the sentence and keep the one that preserves meaning.

Vehicle description order

Record the license plate first, then year, make, model, color, and damage or distinguishing features. Plate first because it is the fastest unique identifier.

Person description order

Note sex, approximate age, height, build, hair, facial hair, clothing, scars or tattoos, then gait and speech. A fixed order prevents skipping details under stress.

Weapon focus

Stress narrows attention toward a threat, often a weapon, causing observers to miss other details. Cross-check accounts with witnesses and video recordings.

Zone scanning

Dividing a scene into fixed zones and recording details in each in the same order. Systematic scanning reduces omissions compared with undirected staring.

Conditional job offer

An offer contingent on remaining steps: psychological evaluation, medical examination, and academy admission. It follows successful completion of the oral board.

Polygraph channels

The instrument records respiratory, electrodermal, and cardiovascular activity. An inconclusive result typically leads to a second examination rather than automatic disqualification.

Background disqualifiers

Common automatic disqualifiers include felony convictions, domestic violence convictions, illegal drug sales, dishonorable military discharge, and falsifying the application itself.

Oral board scoring

Interview panels rate communication, judgment, integrity, and stress tolerance on a fixed scale. Specific past behavior examples score better than hypothetical answers.

Sixth Amendment counsel

The right to counsel attaches when formal adversarial proceedings begin, such as indictment or arraignment, not merely when custody begins.

Use of force standard

Objective reasonableness under the totality of circumstances, including offense severity, immediate threat, and active resistance. The test is not hindsight or subjective intent.

Pursuit decision factors

Seriousness of the offense, risk to the public, road and weather conditions, traffic density, and alternatives such as air support. Supervisors may terminate any pursuit.

Due regard requirement

Emergency vehicle privileges do not excuse reckless driving. Officers must still drive with due regard for the safety of all persons using the roadway.

Sobriety test triad

Standardized field sobriety tests are horizontal gaze nystagmus, walk-and-turn, and one-leg stand, supported by driving observations and chemical test results.

Advance warning area

The first part of a temporary traffic control zone, where signs and cones alert drivers so they can slow and change lanes before reaching workers.

Report chronology

Narratives proceed in time order with short paragraphs and headings for arrival, investigation, arrest, and disposition, so a reader can follow events without rereading.

Time recording in reports

Use 24-hour time and month-day-year dates, and identify the source of each time, such as dispatch, the officer's watch, or a video timestamp.

Sequence markers

Words such as before, after, meanwhile, and subsequently signal event order in a passage. They are the key to answering sequence questions accurately.

Selective observation

Attention determines what is encoded, so expectation can cause missed details. Systematic scanning and immediate note-taking reduce memory loss and error.
