2. Oregon Sign Shapes: Variable Speed Signs, Bike Box Markings and What the 35-Question DMV Test Covers

Oregon uses both standard signs and digital variable speed signs. black-and-white signs that display a changing speed limit based on real-time weather, traffic, or visibility conditions. These are legally enforceable like any posted speed limit. On Oregon mountain passes, coastal fog zones, and urban bike corridors, sign recognition happens fast. Know every row in this table before your test.

Shape	Diagram	Meaning	Example Sign
Octagon (8-sided)		STOP. come to a complete stop, wheels fully stopped, check all directions, then proceed when clear
Triangle (inverted)		Yield slow down, check traffic; if clear proceed, if not stop and wait until safe to go
Diamond		Hazard ahead; slow down, stay alert, and be ready to stop or steer
Rectangle (vertical)		Legal requirement; obey this sign or face fines and points on your record
Rectangle (horizontal)		Informational sign; read it and use it to navigate or plan your route
Pentagon (5-sided)		School zone ahead; reduce speed and watch for children crossing
Round (circle)		Railroad crossing ahead; slow down, look both ways, and prepare to stop
Pennant		No passing zone; do not attempt to overtake any vehicle ahead
Orange (any shape)		Construction or work zone ahead; slow down, stay alert, and obey all posted signs
Blue (any shape)		Motorist services nearby; exit if you need fuel, food, or medical care
Brown (any shape)		Park or scenic area ahead; follow directional signs to reach it

3. Oregon Regulatory Signs: Violations That Affect Your Driving Privilege and Doubled Fines in Work Zones

Regulatory signs carry legal force in Oregon. violations are moving offenses that affect your driving privilege. Work zone violations face doubled fines under Oregon law. White rectangular signs, prohibitory signs, and lane-control signs are all tested on the Oregon 35-question knowledge exam.

4. Oregon Warning Signs: Cascade Pass Grades, Columbia Gorge Wind, Coastal Fog and Railroad Approaches

Diamond-shaped yellow warning signs flag hazards before you reach them. on Oregon roads that means steep grade warnings on Cascade mountain passes, high-wind advisory signs on Columbia Gorge approaches, fog zones on the Oregon Coast Highway, railroad crossing advances across the Willamette Valley rail network, and school zone signs preceding a 20 mph reduction. Orange marks work zones where fines are doubled in all zones, even when workers are not visible.

5. Oregon Guide Signs: I-5, I-84 Columbia Gorge, US-101 Coast Highway and Every Exit to Crater Lake

Guide signs do not regulate driving. they show destinations, distances, and services. Green = highway navigation. Blue = motorist services. Brown = parks and recreation.

6. Oregon Traffic Signals: Bike Box Red Lights, No Right Turn on Red and Variable Speed Enforcement

Flashing red = stop sign. Flashing yellow = yield. Oregon test covers all signal types. plus bike box signals: when a traffic signal is red at a bike box intersection, you must stop behind the green box and no right turn on red is allowed. Variable speed limit signs (digital black-and-white) change the enforceable speed limit in real time.

Standard Traffic Lights

Flashing Signals

Pedestrian Signals

Key test point: Flashing red = stop sign. Flashing yellow = yield. At bike box intersections: stop behind the green box; no right turn on red. All tested on the Oregon DMV exam.

7. Oregon Pavement Markings: Green Bike Boxes, Sharrow Symbols and the 35 mph Bicycle Passing Rule

Yellow lines separate opposing traffic. White lines separate same-direction traffic. Oregon test covers lane lines, road arrows, and unique pavement markings: green-painted bike boxes at intersections, sharrow (shared lane) markings indicating cyclists may occupy the full lane, and green bike lanes. Above 35 mph, you may only pass a cyclist if you leave enough distance to prevent contact if they fall.

Line Colors

Line Types

Pavement Symbols & Special Markings

Key test point: Yellow lines always separate opposing traffic. White lines always separate same-direction traffic. This is a foundational rule that appears on nearly every DMV exam.

8. Oregon Work Zone Signs: Fines Doubled in ALL Zones: Even When Workers Are Not Visible

Orange traffic control devices define every Oregon work zone. Oregon law is clear: traffic fines are doubled in all work zones. The temporary speed posted in a work zone applies at all times, even if workers are not visible. The reduced speed limit stays in effect until you see an End Work Zone Speed Limit sign or another posted speed limit sign. Yield to workers.

• You must obey flaggers and automated devices in Oregon work zones even if their direction conflicts with existing signs.
• Oregon fines are doubled in all work zones, the temporary speed limit applies even when workers are not visible, until you see an End Work Zone sign.
• Work zones can change traffic flow. expect signs, cones, flaggers, and lane markings to guide you through.
• Never drive around or under a crossing gate at railroad crossings within a work zone. it is against the law and extremely dangerous.

Key test point: Orange always means construction or work zone. If you see orange, reduce speed and increase following distance immediately.

9. Oregon Railroad Crossings: Stop at Least 15 Feet Out and Never Drive Around a Gate: Even While It is Moving

When required to stop at an Oregon railroad crossing, stop at the stop line. if there is no stop line, stop at least 15 feet from the nearest rail. It is against the law to drive around or under a crossing gate while it is down, or while it is being raised or lowered. At crossings with multiple tracks, look carefully for a second train from either direction before crossing.

• The round yellow Railroad Advance sign is the first sign. a railroad crossing is ahead. Slow down and prepare to stop.
• Stop at least 15 feet from the nearest rail when: flashing red lights activate, a stop sign is posted, a flagger signals, or an approaching train is clearly visible or dangerously close.
• It is against the law to drive around or under a crossing gate while it is down or while it is being raised or lowered, this specific "while moving" clause is Oregon law and is tested.
• All school buses, hazmat vehicles, and some school activity vehicles must stop at railroad tracks. be prepared to stop when following these vehicles.
• Trains are closer than they appear and cannot stop quickly. One train may be blocking the view of another. always look both ways.

Key test point: Oregon prohibits driving around a gate even while it is being raised or lowered. Stop at least 15 feet from the nearest rail. Both rules are tested on the Oregon DMV exam.

10. Oregon School Zone Speed (20 mph): Three Separate Triggers: Flashing Light, School Hours, or Children Present

Pentagon-shaped school zone signs in Oregon mark the beginning of school zones. The school speed zone is 20 mph and is enforced under three separate triggers: (1) a yellow light on the sign is flashing; (2) it is between 7 a.m. and 5 p.m. on a day school is in session; or (3) children are present at the crosswalk at any day or time. If unsure whether school is in session, slow to 20 mph.

• Oregon school speed zones are 20 mph under three triggers: flashing yellow light on sign; school hours 7am-5pm on school days (if unsure, slow to 20); or children present at the crosswalk at any time.
• Stop and yield to children when they enter the crosswalk or when a school crossing guard signals you to stop. Remain stopped until children clear the crosswalk completely.
• On a 4-lane road with a painted median or turn lane: when a school bus is stopped with red lights flashing, only traffic behind the bus must stop. oncoming traffic may proceed.
• School buses and some school activity vehicles must stop at railroad tracks. treat them the same as school buses.

Key test point: The pentagon shape is used exclusively for school signs. No other sign category uses this shape. making it one of the easiest shapes to identify on the exam.

11. Oregon Pedestrian and Bike Signs: Bike Boxes, Sharrows, No Right Turn on Red and the 35 mph Passing Rule

Pedestrians have right-of-way in all Oregon crosswalks. Oregon has some of the most detailed bicycle rules of any state: green-painted bike boxes at intersections (stop behind the box; no right on red), sharrow markings, designated bike lanes, and a speed-based passing rule. above 35 mph, you may only pass a cyclist if you leave enough distance to prevent contact if they fall. Both sign types use fluorescent yellow-green and are tested on the Oregon DMV exam.

• Pedestrians have right-of-way in all Oregon crosswalks. marked or unmarked.
• Bike boxes: green painted boxes at intersections where cyclists stage in front of traffic. You must stop behind the box when the light is red. No right turn on red at these intersections. On green, signal and yield to cyclists on the right before turning.
• Sharrow markings: two chevrons above a bicycle symbol painted on the road indicate cyclists may be in the lane. Yield as needed.
• Do not drive or park in a bike lane. Do not move into a bike lane in preparation for a turn. You may cross a bike lane only when turning or entering/leaving a driveway or alley.
• At speeds greater than 35 mph, you may only pass a cyclist in your lane if you leave enough distance to prevent contact if the cyclist falls into your path.
• Yield to cyclists in bike lanes or on sidewalks before turning across them. same as for other vehicle types.
• Fluorescent yellow-green is used for both school and pedestrian/bike signs. the shape distinguishes between them.

Key test point: Pedestrians always have right-of-way at crosswalks. marked or unmarked. This rule appears on virtually every state DMV exam.

12. How to Pass Oregon 35-Question DMV Test: Bike Boxes, Variable Speed Signs and the Gate Rule Nobody Expects

• 35 questions, 28 correct required. $7 fee. Take it online at DMV2U.Oregon.gov anytime. After 4 online attempts, you must test at a DMV office. Practice questions are in the back of the Oregon Driver Manual.
• Variable speed signs are enforceable. Black-and-white digital signs that say "speed limit" are legally enforceable. the speed they display is the limit right now, based on real-time conditions. Yellow advisory signs recommend a speed but are not a posted limit.
• Work zone fines are doubled in ALL zones. Oregon is explicit. the temporary speed applies even when workers are not visible, and stays in effect until you see an End Work Zone or another speed limit sign.
• Bike boxes: stop behind, no right on red. Green boxes at intersections = stop behind the line. No right turn on red. On green, yield to cyclists before turning right. This is a Portland-area and statewide sign type that appears on the test.
• 35 mph bicycle passing rule. Above 35 mph, you may only pass a cyclist in your lane if you leave enough distance to prevent contact if they fall. If you cannot, slow down and wait.
• Railroad gate rule: also applies while gate is moving. You cannot drive around or under a gate while it is down OR while it is being raised or lowered. That "while moving" condition is Oregon-specific and is tested.
• School zone: three triggers. Flashing yellow light. School hours 7am-5pm on school days. Children present at any time. If unsure if it is a school day, slow to 20 mph. that is the Oregon manuals explicit guidance.
• Oregon speed limits. Alleys/narrow residential: 15 mph. Business districts/school zones: 20 mph. Residential/parks: 25 mph. All other roads: 55 mph unless posted.
• Flashing signals. Flashing red = full stop. Flashing yellow = slow and yield.
