32 cards. Read the term and the definition here. The deck at the top of this page is optional.
- Speed limit sign
- A white rectangular regulatory sign with black numerals giving the maximum lawful speed in miles per hour. Oregon's default limits include 55 mph on most rural highways and 65 mph on rural interstates.
- Stop sign shape
- An eight-sided red octagon with white STOP letters. Oregon law requires a complete stop at the stop line or crosswalk before proceeding when the way is clear.
- Yield sign
- A red-and-white downward-pointing triangle. Drivers slow down and stop only if necessary to let cross traffic or pedestrians pass before entering the roadway.
- Right turn on red
- In Oregon, a right turn after a full stop is allowed at most red signals unless a NO TURN ON RED sign prohibits it. Yield to pedestrians and cross traffic first.
- Lane-use arrow signs
- Black-background signs with white arrows showing how each lane may be used. A curved arrow marks a mandatory turn lane, and a red X marks a closed lane.
- Curve warning sign
- A yellow diamond with a black curved arrow showing a bend ahead. An advisory speed plaque below it gives a recommended safe speed for the curve.
- Road narrows sign
- A yellow diamond showing a roadway pinching from both sides, the right, or the left. It warns that the travel width decreases ahead.
- Hill and grade signs
- Yellow diamonds warning of steep upgrades or downgrades, sometimes with a percentage plaque. A truck symbol warns of slow heavy vehicles on the grade.
- Slippery when wet
- A yellow diamond warning that the pavement loses traction in rain. The hazard may exist only during wet weather, but the sign stays posted year-round.
- Orange work zone signs
- Orange signs with black legends mark temporary traffic control areas. Examples include ROAD WORK AHEAD, LANE CLOSED AHEAD, and FLAGGER AHEAD.
- Flagger authority
- A flagger holding a STOP/SLOW paddle controls traffic with the same authority as a stop sign. Stop when the paddle reads STOP and proceed only on SLOW.
- Detour sign
- An orange guide sign with black arrows routing traffic around a closure. Drivers should follow posted detour markers rather than improvising through the work area.
- Work zone speed limits
- Reduced speeds posted on orange signs in work zones are enforceable. Oregon can double fines for moving violations when workers are present in the zone.
- Interstate route shield
- A red, white, and blue shield marking an Interstate highway. U.S. routes use a white shield, and Oregon state routes use a separate state marker.
- Exit numbers in Oregon
- Oregon interstate exit numbers match the milepost of the exit. Numbers generally increase as you travel north or east along the route.
- Blue service signs
- Blue guide signs mark motorist services such as gas, food, lodging, and hospitals. Brown signs instead mark recreation areas and points of interest.
- Crossbuck sign
- A white X-shaped sign with RAILROAD CROSSING lettering at the tracks. It means yield to trains; a train always has the right of way.
- Railroad advance warning
- A yellow diamond with a round black railroad symbol and a distance plaque. It warns of a crossing ahead so drivers can slow and prepare to stop.
- Multiple track plaque
- A small plaque below a crossbuck showing the number of tracks. More than one track means a second train may follow the first.
- Railroad pavement markings
- A white X with the letters RR painted before a crossing, plus a stop line. Stop before the line when a train is approaching.
- School zone sign color
- Fluorescent yellow-green pentagons and diamonds mark school zones and crossings. The bright color is reserved for school and pedestrian warnings.
- Oregon school speed zone
- A posted school zone speed, commonly 20 mph, applies when children are present or when flashing beacons operate. The plaque states which condition applies.
- Shared-lane marking
- A white bicycle symbol with two chevrons painted in a travel lane. It shows that bicyclists and motor vehicles share the lane, not a separate bike lane.
- Pedestrian signal heads
- Signal displays showing a walking person for WALK and an upraised hand for DON'T WALK. A flashing hand means finish crossing, not start.
- Pennant sign
- A right-pointing triangular pennant marking a NO PASSING ZONE. It is the only sign shape used for that purpose.
- Diamond sign meaning
- Yellow diamonds are used only for warning signs. They alert drivers to conditions ahead and do not by themselves change the speed limit.
- Red circle with slash
- A symbol on white regulatory signs meaning the pictured action is prohibited. A green circle instead means the action is permitted.
- Yellow pavement lines
- Yellow lines separate traffic moving in opposite directions. A solid yellow line on your side means no passing; a broken line permits passing when safe.
- Stop bar
- A wide white line across the lane at an intersection or crosswalk. When a sign or signal requires a stop, stop before the bar, not on it.
- Delineator posts
- Small reflective posts along the roadside. White reflectors mark the right edge, and yellow reflectors mark the left edge of a divided highway.
- Object marker stripes
- Markers on obstructions use diagonal stripes that slope downward toward the side you should pass. They warn of barriers close to the travel lane.
- Painted channelizing island
- White diagonal stripes separating traffic from an area you must not drive through. They often accompany lane-use or turn signs at intersections.
