Oregon Permit Test Study Guide (2026)

Cover every topic on the Oregon DMV permit test, ranked by how often they show up on the real exam.

The Oregon Driver Manual is your main study tool. It explains traffic laws, signs, and safe driving in plain language. The DMV writes the test from this manual. Read each chapter and take the official online practice test. The manual is in English and Spanish, with audio if you prefer to listen.

Oregon Speed Limits

Speed limits are one of the most-tested topics on the OR permit exam, and the questions usually test Oregon's statutory default limits -- what the speed is when no sign is posted. Under ORS 811.105, Oregon's defaults are: 15 mph in alleys and narrow residential roadways (under 18 feet wide), 20 mph in business districts and school zones, 25 mph in residential districts, public parks, and ocean shores, and 55 mph on highways with no other posted limit. Always obey the basic-speed law: never drive faster than is safe for current conditions, even if you are under the posted or statutory limit. Rain, fog, snow, glare, and heavy traffic all require you to slow below the sign.

Alcohol & BAC Limits

Expect at least one alcohol question on the Oregon permit test. Memorize the three BAC thresholds: 0.08% is the legal limit for drivers age 21 and older, 0.04% is the limit for anyone driving with a commercial driver license (CDL), and Oregon is a zero-tolerance state for drivers under 21 -- any measurable amount of alcohol, not a specific percentage, triggers consequences. A first violation is an automatic 90-day license suspension (1 year for a second); a BAC of 0.08% or higher on top of that brings full adult DUII charges. Oregon also has an implied-consent law: by accepting your license, you have already agreed to a breath, blood, or urine test if an officer suspects you of impaired driving. Refusing the test triggers an automatic license suspension on top of any DUII charge.

Right-of-Way Rules

Right-of-way is the single most-missed topic across every state's permit test. The rules are simple once you memorize them. At a 4-way stop, the first vehicle to fully stop goes first; if two arrive together, the driver on the right has the right of way. At an uncontrolled intersection, yield to any vehicle already in the intersection and to the driver on your right. At roundabouts, yield to traffic already circulating and enter only when there is a safe gap. Always yield to pedestrians in any crosswalk, marked or unmarked, and to emergency vehicles with lights and sirens — pull right and stop. When turning left across oncoming traffic, you must yield to oncoming vehicles. Yield does not give you the right of way; it requires you to give it up.

Following Distance & Safety

The Oregon driver manual's standard is a 2-to-4-second following distance: pick a fixed point on the road, wait for the vehicle ahead of you to pass it, then count "one-thousand-one, one-thousand-two..." At speeds above 30 mph, use 4 seconds or more. Increase the gap further -- the manual doesn't give a fixed multiplier -- on wet or slippery roads, when following large vehicles, motorcycles, or bicycles, when towing a heavy load, in poor visibility, and in work zones. Mirrors do not eliminate blind spots -- always glance over your shoulder before changing lanes.

Road Sign Colors & Shapes

Road signs on the OR permit test follow the federal Manual on Uniform Traffic Control Devices, so shapes and colors are consistent across the country. Memorize the shapes first: octagon always means stop, downward triangle means yield, diamond means warning, pentagon marks a school zone, round warns of a railroad crossing, and horizontal rectangle is a guide sign. Then learn the colors: red is stop or prohibition, yellow is general warning, orange is construction, green is directions and exits, blue is driver services, brown is recreation, and fluorescent yellow-green is for schools and pedestrians. Practice identifying signs by shape and color alone — see the full visual cheat sheet on our Oregon road-signs page.

Key Oregon Numbers to Memorize

If you only remember a handful of facts going into the test, make it these. Every one of them maps to questions that have appeared on the real OR exam.

Parking Rules

Parking questions on the Oregon permit test cover two patterns everywhere. For parallel parking, your wheels should be no more than 12 inches from the curb. For hill parking, the kerb rule decides which way your front wheels point: facing downhill (with or without a curb), turn the wheels toward the curb; facing uphill with a curb, turn the wheels away from the curb so they rest against it; facing uphill with no curb, turn the wheels toward the edge of the road. Always set the parking brake and leave the car in park (or in low gear with a manual).

Oregon's no-parking zones (ORS 811.550) you must memorize: within 10 feet of a fire hydrant, within 20 feet of a marked or unmarked crosswalk at an intersection, within 50 feet of a stop sign, yield sign, or traffic signal if parking there would obstruct another driver's view of it, within 50 feet of the nearest rail at a railroad crossing, and never in front of a driveway, on a sidewalk, or in a marked bus zone.

GDL Restrictions (OR)

Oregon's Graduated Driver License program has three exact stages. Instruction permit: apply at age 15, with a licensed driver 21 or older seated beside you at all times while practicing. Provisional license: apply at 16 or 17, but only after holding the permit at least 6 months and completing either 100 hours of supervised practice, or 50 hours if you finish an ODOT-approved driver education course (either way, whoever signs off on your hours must have held a valid license for at least 3 years). Provisional restrictions last until you turn 18 or for one year, whichever comes first: no driving between midnight and 5 a.m. (exceptions for work, school events with no other transportation, employment, or when accompanied by a licensed driver 25 or older); no passengers under 20 outside your immediate family for the first 6 months, then no more than 3 such passengers for the second 6 months; and no use of any mobile communication device while driving -- including hands-free -- if you're under 18. Expect 1-3 GDL questions on the OR exam.

DUI & Drug Laws

DUI questions go beyond the BAC limits in Section 2. Three concepts you must know: implied consent means refusing a chemical test triggers automatic license suspension on top of any DUI charge. Prescription and over-the-counter drugs can also impair driving — antihistamines, sleep aids, painkillers, and some cold medicines list "do not operate heavy machinery" warnings, and driving impaired by them is a DUI even if you have a valid prescription. Marijuana — even where state-legal — is treated like alcohol for driving: any detectable impairment can result in a DUI, and edibles can take 1–3 hours to peak. The only safe BAC and the only safe THC level for driving is zero. There is no quick way to sober up; only time will lower your BAC.
