Space Cushion

The clear area around a vehicle that gives the driver time and room to react to hazards. Instructors teach following-distance and lane-position habits that preserve this margin at all speeds and in poor weather.

Related: Following Distance Rule, Risk Perception
Following Distance Rule

Oregon's guidance that a driver should stay at least two seconds behind the vehicle ahead in ideal conditions, adding a second for each adverse factor such as rain, darkness, or heavy traffic.

Related: Space Cushion, Basic Speed Rule
Basic Speed Rule

Oregon's requirement that a driver never travel faster than is reasonable and prudent for current conditions, regardless of the posted limit. Snow, fog, curves, and congestion can make a legal speed unsafe.

Related: Posted Speed Limit, Following Distance Rule
Posted Speed Limit

The maximum lawful speed for a road segment under normal conditions, set by statute or sign. It is a ceiling, not a target, and drivers must slow below it when hazards or weather demand.

Related: Basic Speed Rule
Right-of-Way

The legal priority to proceed through a conflict point such as an intersection or crosswalk. It is something a driver yields rather than takes, and failure to yield is a leading cause of urban crashes.

Related: Uncontrolled Intersection, Pedestrian Crosswalk
Uncontrolled Intersection

An intersection with no stop signs, yield signs, or traffic signals. Drivers must slow, look, and yield to vehicles already in the intersection or approaching from the right when arriving at the same time.

Related: Right-of-Way, Stale Green Light
Pedestrian Crosswalk

A marked or unmarked portion of roadway designated for people on foot. Oregon drivers must stop for pedestrians in a crosswalk and must not pass a vehicle stopped at one.

Related: Right-of-Way
School Zone Speed

A reduced speed area near a school that applies when children are present or when a flashing sign indicates, depending on posted signage. Instructors must teach students to scan for children and crossing guards.

Related: Posted Speed Limit, Hazard Scanning
Stale Green Light

A green signal that has been green for a while and may be about to change. Drivers should cover the brake and prepare to stop rather than accelerate to beat the light.

Related: Uncontrolled Intersection, Hazard Scanning
Hazard Scanning

The systematic, continuous search of the roadway ahead, to the sides, and behind for developing risks. Instructors teach a moving eye pattern rather than a fixed stare at the car ahead.

Related: Space Cushion, Stale Green Light, Risk Perception
Risk Perception

A driver's ability to notice and judge the likelihood of danger before it becomes urgent. Novice drivers often underestimate risk, so instruction focuses on naming hazards aloud and predicting what others may do.

Related: Hazard Scanning, Space Cushion
Visual Lead Time

How far ahead a driver looks, commonly described as 12 to 15 seconds of travel in urban areas and more at highway speed. Adequate lead time lets a driver plan lane and speed changes early.

Related: Hazard Scanning
Smith System

A widely taught five-part scanning method: aim high in steering, get the big picture, keep your eyes moving, leave yourself an out, and make sure others see you. It supports hazard perception training.

Related: Hazard Scanning, Space Cushion
IPDE Process

A structured driving strategy: identify hazards, predict what may happen, decide on an action, and execute it. Instructors use it to turn passive observation into deliberate, explainable decisions.

Related: Risk Perception, Commentary Driving
Commentary Driving

A teaching technique in which the student or instructor narrates hazards, intentions, and planned actions aloud while driving. It makes the student's perception and decision process visible for coaching.

Related: IPDE Process, Hazard Scanning
Defensive Driving

Driving that assumes other road users may make mistakes and prepares for them. It emphasizes early adjustment, generous following distance, and avoiding reliance on the other driver to do the right thing.

Related: Space Cushion, Risk Perception
Distracted Driving

Operating a vehicle while attention is diverted to another task such as phone use, eating, or grooming. Oregon law restricts handheld device use, and instructors teach pre-trip setup so attention stays on the road.

Related: Hazard Scanning
Impaired Driving

Driving with a blood alcohol concentration at or above the legal limit or while affected by drugs or medication. Oregon's limit for drivers 21 and older is 0.08 percent, with lower limits for commercial and underage drivers.

Related: Defensive Driving
Zero Tolerance

The Oregon rule that drivers under 21 may not drive with any measurable alcohol in their system. A first offense carries license consequences even at very low concentrations.

Related: Impaired Driving
Graduated Driver Licensing

Oregon's staged licensing system with instruction permit, provisional license, and full license phases. Each phase restricts passengers, hours, and device use to reduce crash risk for new drivers.

Related: Instruction Permit, Provisional Driver License
Instruction Permit

Oregon's learner stage that allows driving only with a supervising licensed driver meeting age and experience requirements. It requires a knowledge test and vision screening before issuance.

Related: Graduated Driver Licensing, Supervising Driver
Provisional Driver License

The intermediate Oregon license issued to qualified young drivers after holding a permit and completing supervised driving. It carries restrictions on nighttime driving and young passengers.

Related: Graduated Driver Licensing, Instruction Permit
Supervising Driver

A licensed adult who rides with a permit holder and is legally responsible for the vehicle's operation. Oregon sets minimum age and licensing tenure rules for who may supervise.

Related: Instruction Permit
Drive Test

The behind-the-wheel skills examination administered by Oregon DMV to confirm a driver can perform basic maneuvers safely and legally. Scoring focuses on critical errors and habitual unsafe acts.

Related: Critical Driving Error, Provisional Driver License
Critical Driving Error

A mistake during a drive test serious enough to fail the applicant immediately, such as running a red light or requiring examiner intervention to prevent a crash. Instructors drill these scenarios deliberately.

Related: Drive Test
Oregon DMV

The state agency that licenses drivers, administers knowledge and drive tests, and oversees driving schools and instructors. Candidates should know its published manuals and program rules.

Related: Drive Test, Graduated Driver Licensing
Dual Control Vehicle

A training car equipped with a second brake pedal, and often a second mirror, accessible to the instructor. It allows intervention if a student fails to respond to a hazard.

Related: Instructor Intervention, Behind-the-Wheel Lesson Plan
Instructor Intervention

The instructor's timely action, verbal or physical, to prevent a crash or serious error. It must be proportional to the risk and followed by a debrief so the student learns from it.

Related: Dual Control Vehicle, Debrief
Debrief

A structured conversation after a driving session in which student and instructor review what went well, what failed, and what to practice next. It converts experience into retained skill.

Related: Instructor Intervention, Behind-the-Wheel Lesson Plan
Behind-the-Wheel Lesson Plan

A written sequence of objectives, routes, maneuvers, and success criteria for a driving session. It keeps instruction purposeful and lets progress be measured across lessons.

Related: Debrief, Dual Control Vehicle
Lesson Objective

A specific, observable skill the student should perform by the end of a session, such as completing a lane change with signal and mirror checks. Objectives guide route choice and assessment.

Mandatory Reporting

The duty to report certain serious events, such as suspected abuse or a crash during a lesson, to the proper authority. Instructors should know school policy and Oregon reporting requirements.

Related: Instructor Code of Ethics
Transfer of Learning

The extent to which a skill practiced in one setting carries over to real driving. Instructors vary routes and conditions so students generalize rather than memorize a single test course.

Related: Behind-the-Wheel Lesson Plan, Lesson Objective
Threshold Braking

Braking at the maximum force that still allows steering control, just short of lockup or anti-lock activation. It is taught for emergency stops and practiced in controlled, low-speed settings.

Related: Skid Recovery, Instructor Intervention
Skid Recovery

The technique of looking and steering where the driver wants to go while easing off throttle and avoiding hard braking. Practice is limited to safe, low-speed areas under instructor supervision.
