Question 1Regulatory Signs (speed limits, stop/yield, lane use, turning and parking controls)

On a two-lane road in Oregon, a solid yellow line on your side of the center line means which of the following?

  1. Passing is permitted when the road ahead is clear
  2. You may cross the line whenever the vehicle ahead is slow-moving
  3. Passing is allowed only during daylight hours
  4. You may cross the line only to turn into a driveway or side road Correct answer.

Explanation

A solid yellow line on your side of the center line marks a no-passing zone for your direction of travel. You may still cross it to make a left turn into a driveway, side road, or private entrance when it is safe. Passing slower traffic is not a permitted reason to cross.

Question 2Regulatory Signs (speed limits, stop/yield, lane use, turning and parking controls)

In Oregon, the maximum speed limit on most rural interstate freeways unless posted otherwise is which speed?

  1. 65 mph Correct answer.
  2. 75 mph
  3. 70 mph
  4. 55 mph

Explanation

Oregon law sets the default maximum speed on rural interstate freeways at 65 mph unless a different limit is posted. Urban freeway segments and specific corridors may carry lower or higher posted limits. Drivers must always obey the posted sign over the default.

Question 3Regulatory Signs (speed limits, stop/yield, lane use, turning and parking controls)

A red octagonal sign at an intersection requires you to do which of the following?

  1. Slow down and proceed if the way is clear
  2. Yield only to vehicles already inside the intersection
  3. Come to a complete stop before the crosswalk or stop line Correct answer.
  4. Stop only when other traffic is approaching

Explanation

The octagonal red sign is the STOP sign, and it requires a full stop regardless of traffic conditions. You stop at the stop line, before the crosswalk, or at the edge of the intersection if neither is marked. After stopping, you yield to traffic and pedestrians before proceeding.

Question 4Regulatory Signs (speed limits, stop/yield, lane use, turning and parking controls)

An inverted red triangle sign means which of the following?

  1. Yield the right of way to traffic on the cross road Correct answer.
  2. Merge without changing speed
  3. Reduce speed for a work zone ahead
  4. Come to a complete stop and wait for a signal

Explanation

The downward-pointing red triangle is the YIELD sign. You slow down and give the right of way to vehicles and pedestrians on the cross road or approaching ramp. A full stop is required only when traffic conditions make it necessary.

Question 5Regulatory Signs (speed limits, stop/yield, lane use, turning and parking controls)

A white rectangular sign reading 'ONE WAY' with an arrow indicates which of the following?

  1. The road curves in the direction of the arrow
  2. The lane will end and merge in the arrow's direction
  3. Parking is allowed only in the arrow's direction
  4. Traffic on that roadway moves only in the direction the arrow points Correct answer.

Explanation

The ONE WAY sign marks a roadway or lane where all traffic must travel in the direction shown by the arrow. Entering against the arrow is prohibited and dangerous. The sign does not describe parking, merging, or a curve.

Question 6Regulatory Signs (speed limits, stop/yield, lane use, turning and parking controls)

A sign showing a red circle with a diagonal slash over a symbol means which of the following?

  1. The activity shown is required ahead
  2. The activity shown is permitted only at certain hours
  3. The activity shown is prohibited Correct answer.
  4. The activity shown is recommended for safety

Explanation

A red circle with a diagonal slash is the universal prohibition symbol. Whatever symbol appears inside the circle is not allowed at that location. These signs are commonly used for turning, parking, and entry restrictions.

Question 7Regulatory Signs (speed limits, stop/yield, lane use, turning and parking controls)

A white rectangular sign reading 'SPEED LIMIT 45' means which of the following?

  1. 45 mph applies only to trucks
  2. 45 mph is the maximum lawful speed in good conditions Correct answer.
  3. 45 mph is a suggested speed for good conditions
  4. The minimum legal speed is 45 mph

Explanation

A SPEED LIMIT sign sets the maximum lawful speed under favorable conditions. Driving faster than the posted limit is a violation. When conditions such as rain, fog, or ice are poor, the safe speed may be well below the posted maximum.

Question 8Regulatory Signs (speed limits, stop/yield, lane use, turning and parking controls)

A white sign with a red circle and slash over a left-turn arrow means which of the following?

  1. Left turns are permitted after a full stop
  2. Left turns are prohibited Correct answer.
  3. Left turns are allowed on a green arrow only
  4. Left turns are allowed for buses only

Explanation

A slashed red circle over a turn arrow prohibits that turn at the location. The restriction applies at all times unless a supplemental plate states otherwise. Drivers must use another route or turn.

Question 9Regulatory Signs (speed limits, stop/yield, lane use, turning and parking controls)

You are driving in the left lane of a multi-lane Oregon highway and a faster vehicle approaches from behind. What does the keep-right law require?

  1. Speed up until you reach the posted limit
  2. Maintain your lane and speed so the other driver must pass on the right
  3. Flash your brake lights to warn the driver to slow down
  4. Move to the right lane when it is safe to let the faster vehicle pass Correct answer.

Explanation

Oregon's keep-right law requires drivers moving slower than surrounding traffic to use the right lane, and to move right to let faster traffic pass when it is safe. The left lane is intended for passing and faster-moving traffic. Blocking faster traffic in the left lane is a violation.

Question 10Regulatory Signs (speed limits, stop/yield, lane use, turning and parking controls)

You approach a flashing red traffic signal at an intersection. How should you proceed?

  1. Slow down and proceed without stopping if no traffic is present
  2. Stop completely, then proceed when it is safe, as at a stop sign Correct answer.
  3. Treat it as a green light and continue at speed
  4. Wait for the signal to turn green before moving

Explanation

A flashing red signal has the same meaning as a stop sign: come to a complete stop, yield to traffic and pedestrians, then proceed when safe. A flashing yellow, by contrast, means slow down and proceed with caution. A flashing red never turns green on its own.

Question 11Regulatory Signs (speed limits, stop/yield, lane use, turning and parking controls)

A white rectangular sign reading 'NO PARKING 8 AM TO 5 PM' is posted along a curb. What does it allow?

  1. Parking during the stated hours if you display a permit
  2. Parking for up to 30 minutes during the stated hours
  3. Parking only outside the stated hours Correct answer.
  4. Parking at any time if you remain in the vehicle

Explanation

A time-limited NO PARKING sign prohibits parking during the hours listed and allows it at other times, subject to any other posted restrictions. Remaining in the vehicle does not exempt a driver from a no-parking restriction. Permit exceptions would be stated on the sign.

Question 12Regulatory Signs (speed limits, stop/yield, lane use, turning and parking controls)

You are in a lane marked with a white left-turn arrow painted on the pavement and a sign showing a left-turn-only arrow. What is required?

  1. You must change lanes before the intersection
  2. You may continue straight if no traffic is present
  3. You must turn left from that lane Correct answer.
  4. You may turn left or go straight, whichever is safer

Explanation

A left-turn-only arrow, whether painted on the pavement or shown on a sign, designates the lane exclusively for left turns. Drivers in that lane must turn left. If you intended to go straight, you needed to choose a through lane earlier.

Question 13Regulatory Signs (speed limits, stop/yield, lane use, turning and parking controls)

A sign reading 'RIGHT TURN ON RED AFTER STOP' is posted at an intersection. What does Oregon law require?

  1. Come to a complete stop, then turn right when pedestrians and cross traffic are clear Correct answer.
  2. Slow to a rolling stop before turning right
  3. Wait for a green arrow before turning right
  4. Turn right without stopping if no vehicles are visible

Explanation

Oregon generally permits a right turn on red after a complete stop, unless a sign prohibits it, and the driver must yield to pedestrians and cross traffic. The stop must be full, not rolling. A green arrow is not required when the sign allows the turn after stopping.

Question 14Regulatory Signs (speed limits, stop/yield, lane use, turning and parking controls)

A yellow diamond sign showing a black arrow curving sharply to the right warns of what, and what should you do?

  1. A sharp right curve ahead; slow down before entering it Correct answer.
  2. A right lane ending; merge left immediately
  3. A right turn permitted on red; proceed with caution
  4. A one-way road to the right; yield before turning

Explanation

A yellow diamond with a curving arrow warns of a curve ahead and shows its direction. Because the curve is sharp, you should reduce speed before entering it rather than braking hard within the curve. Lane-end, turn-on-red, and one-way information use different signs.

Question 15Regulatory Signs (speed limits, stop/yield, lane use, turning and parking controls)

You are approaching a school zone sign with a flashing yellow light during posted hours. What is required?

  1. Stop completely and wait for the light to stop flashing
  2. Maintain the normal speed limit because the light is only advisory
  3. Slow to the posted school zone speed and watch for children Correct answer.
  4. Sound your horn continuously through the zone

Explanation

When a school zone signal is flashing during the designated hours, the reduced school zone speed limit is in effect. Drivers must slow to that posted speed and be alert for children near the roadway. The flashing light makes the reduced limit enforceable, not merely advisory.

Question 16Regulatory Signs (speed limits, stop/yield, lane use, turning and parking controls)

A white sign reading 'DO NOT PASS' appears on a two-lane road. What does it mean for your direction of travel?

  1. You may not pass other vehicles in your direction of travel Correct answer.
  2. You may pass only vehicles traveling below 30 mph
  3. You may not be passed by vehicles behind you
  4. You may pass only if the road ahead is clear for one mile

Explanation

A DO NOT PASS sign prohibits passing vehicles traveling in your direction until the restriction ends or a pass-permitted sign appears. It is typically placed where sight distance or road geometry makes passing unsafe. It does not restrict vehicles behind you from passing when lawful.

Question 17Regulatory Signs (speed limits, stop/yield, lane use, turning and parking controls)

A curb is painted red in Oregon. What does this indicate?

  1. Loading and unloading is permitted at all times
  2. Parking is reserved for disabled placard holders
  3. Parking, stopping, and standing are prohibited Correct answer.
  4. Parking is allowed for up to 15 minutes

Explanation

A red curb marks a fire zone where parking, stopping, and standing are prohibited. Drivers may not wait there even briefly. Blue curbs mark disabled parking, and yellow curbs typically restrict stopping for loading.

Question 18Regulatory Signs (speed limits, stop/yield, lane use, turning and parking controls)

You want to make a left turn at an intersection and a sign reads 'LEFT TURN YIELD ON GREEN.' What should you do when the light is green?

  1. Turn immediately because green gives you the right of way
  2. Wait for a green arrow before entering the intersection
  3. Enter the intersection, yield to oncoming traffic, and turn when clear Correct answer.
  4. Turn only after the light turns yellow

Explanation

A LEFT TURN YIELD ON GREEN sign means a green ball does not give left-turning drivers the right of way. You may enter the intersection and complete the turn only after yielding to oncoming traffic and pedestrians. A green arrow, when provided, would give protected right of way.

Question 19Regulatory Signs (speed limits, stop/yield, lane use, turning and parking controls)

A white rectangular sign shows a bicycle symbol inside a lane marking. What does this sign indicate?

  1. The lane is reserved exclusively for bicycles
  2. The lane is a shared lane where bicycles may use the full lane Correct answer.
  3. Bicycles must ride on the sidewalk in that area
  4. Bicycles are prohibited from the lane

Explanation

A shared lane marking, often called a sharrow, indicates that bicyclists may use the full lane and that motorists should share it. It does not reserve the lane exclusively for bicycles or ban them. Drivers should allow safe passing distance when overtaking a bicyclist.

Question 20Regulatory Signs (speed limits, stop/yield, lane use, turning and parking controls)

An orange diamond sign reading 'ROAD WORK AHEAD' appears with a reduced speed limit plate. What is the correct response?

  1. Stop and wait for a flagger before proceeding
  2. Maintain the normal limit because workers may not be present
  3. Slow to the posted work zone speed and stay alert for workers and equipment Correct answer.
  4. Change lanes immediately regardless of markings

Explanation

Orange signs mark work zones, and a posted reduced speed in a work zone is enforceable whether or not workers are visible. Drivers should slow to the posted speed and watch for workers, equipment, and narrowed lanes. Stopping is required only when a flagger or signal directs it.

Question 21Regulatory Signs (speed limits, stop/yield, lane use, turning and parking controls)

A white sign reading 'NO U-TURN' is posted at a divided highway median opening. What does it prohibit?

  1. Making a U-turn at that location Correct answer.
  2. Crossing the median on foot
  3. Turning left into the median
  4. Backing into the median opening

Explanation

The NO U-TURN sign prohibits reversing direction at that specific location, typically because sight distance or traffic patterns make it unsafe. Other movements such as a lawful left turn may still be allowed unless separately restricted. Drivers should continue to the next legal opening to reverse direction.

Question 22Regulatory Signs (speed limits, stop/yield, lane use, turning and parking controls)

You are driving in the center lane of a three-lane road where pavement arrows in that lane point in both directions. What does this indicate?

  1. The lane is closed to all traffic during rush hour
  2. The lane is a two-way left-turn lane for traffic from either direction Correct answer.
  3. The lane is reserved for emergency vehicles
  4. The lane may be used for passing in either direction

Explanation

A center lane marked with arrows pointing both ways is a two-way left-turn lane. Drivers from either direction may enter it only to prepare for a left turn, and it may not be used for passing or through travel. It is not an emergency vehicle lane.

Question 23Regulatory Signs (speed limits, stop/yield, lane use, turning and parking controls)

On a road with no posted speed limit in a business district, what speed does Oregon law generally establish as the maximum?

  1. 35 mph
  2. 15 mph
  3. 20 mph Correct answer.
  4. 25 mph

Explanation

Oregon law sets a default maximum of 20 mph in business districts when no other speed is posted. Residential districts default to 25 mph, and school zones are lower when children are present. Drivers must still reduce speed below the default when conditions require.

Question 24Regulatory Signs (speed limits, stop/yield, lane use, turning and parking controls)

A sign reading 'CENTER LANE ONLY' with a left-turn arrow is posted above a lane approaching an intersection. A driver who intends to go straight is in that lane. What is the correct action?

  1. Back up to the previous intersection
  2. Stop in the lane and wait for a gap to merge right
  3. Turn left as the lane requires or change lanes earlier if a lawful through lane exists Correct answer.
  4. Continue straight from that lane because through travel is always allowed

Explanation

A lane designated CENTER LANE ONLY with a turn arrow is reserved for the indicated movement. A driver who needs to go straight should have chosen a through lane earlier; once committed, the lawful options are to follow the lane's movement or change lanes where permitted. Continuing straight from a turn-only lane is a violation.

Question 25Regulatory Signs (speed limits, stop/yield, lane use, turning and parking controls)

A white sign with a red circle and slash over a parking symbol is posted beside a curb, and a separate green sign below reads '2 HOUR PARKING 9 AM-6 PM.' How should a driver interpret the combination?

  1. Parking is allowed for two hours at any time of day
  2. Parking is prohibited at all times regardless of the green sign
  3. Parking is free for two hours but prohibited for commercial vehicles
  4. Parking is limited to two hours between 9 AM and 6 PM and prohibited outside those hours Correct answer.

Explanation

When a prohibition sign is combined with a time-limited permission plate, the permission defines when and how long parking is allowed. Here, parking is limited to two hours during the stated hours and is not permitted outside them. Reading only one sign would give an incomplete picture.

Question 26Regulatory Signs (speed limits, stop/yield, lane use, turning and parking controls)

In Oregon, a white rectangular sign with black lettering that reads 'KEEP RIGHT' beside a raised median tells drivers to do what?

  1. Turn left across the median
  2. Reduce speed to 25 mph at the median
  3. Stop before entering the median area
  4. Pass the median on its right side Correct answer.

Explanation

Regulatory signs with white backgrounds and black legends carry mandatory instructions. 'KEEP RIGHT' directs traffic to pass to the right of the median or obstacle rather than crossing it. It is not a stop or speed instruction.

Question 27Regulatory Signs (speed limits, stop/yield, lane use, turning and parking controls)

A white sign reading 'SPEED LIMIT 55' with a smaller plate beneath reading 'TRUCKS 50' applies how?

  1. Trucks may exceed 55 mph when passing
  2. Trucks are limited to 50 mph and other vehicles to 55 mph Correct answer.
  3. The 50 mph plate applies only during daylight
  4. All vehicles are limited to 50 mph

Explanation

The main sign sets the limit for the general traffic stream at 55 mph. The auxiliary plate creates a lower limit of 50 mph for trucks only. Each limit applies to the vehicles named on its sign.

Question 28Regulatory Signs (speed limits, stop/yield, lane use, turning and parking controls)

You are entering a freeway from an on-ramp posted with a white 'YIELD' sign and no merge lane markings. What does Oregon law require?

  1. Slow or stop as needed and give way to freeway traffic Correct answer.
  2. Sound your horn to request space in the through lane
  3. Accelerate to freeway speed and merge without yielding
  4. Come to a complete stop before merging

Explanation

A YIELD sign requires the entering driver to let traffic on the freeway proceed first. The driver should adjust speed, slowing or stopping if necessary, and merge only when a safe gap exists. A full stop is required only when traffic conditions demand it.

Question 29Regulatory Signs (speed limits, stop/yield, lane use, turning and parking controls)

A white sign shows a black arrow pointing straight ahead with the word 'ONLY' beneath it, mounted over a lane approaching an intersection. What does it require of a driver in that lane?

  1. Turn right after stopping
  2. Merge left before the intersection
  3. Proceed straight through the intersection only Correct answer.
  4. Stop and wait for a green arrow signal

Explanation

A straight-arrow ONLY sign designates the lane for through movement exclusively. Drivers in that lane must continue straight and may not turn from it. The sign does not require a stop or a lane change.

Question 30Regulatory Signs (speed limits, stop/yield, lane use, turning and parking controls)

An Oregon sign reading 'NO TURN ON RED' is posted at an intersection. What does it change about normal right-turn-on-red rules?

  1. Right turns on red are prohibited at that intersection Correct answer.
  2. Right turns on red are allowed only from the left lane
  3. Right turns on red are allowed only for trucks
  4. Right turns on red remain allowed after a full stop

Explanation

Oregon generally permits a right turn after stopping at a red light unless a sign prohibits it. A 'NO TURN ON RED' sign removes that permission at the posted location. Drivers must then wait for a green signal before turning.

Question 31Regulatory Signs (speed limits, stop/yield, lane use, turning and parking controls)

A white sign reading 'NO PARKING ANY TIME' stands beside a curb with no painted color. What does it mean for a driver?

  1. Parking is allowed only on weekends
  2. Parking is allowed for up to 15 minutes
  3. Parking is allowed only for delivery vehicles
  4. Parking is prohibited at all hours Correct answer.

Explanation

'NO PARKING ANY TIME' is an absolute restriction that applies around the clock. Curb paint is not required for a posted no-parking zone to be enforceable. A driver may not leave the vehicle standing there at any hour.

Question 32Regulatory Signs (speed limits, stop/yield, lane use, turning and parking controls)

You see a white sign reading 'NO PARKING 7 AM TO 9 AM' above a plate reading 'STREET CLEANING.' You arrive at 8:15 AM. What is the correct action?

  1. Park only with hazard lights flashing
  2. Park because street cleaning has likely finished
  3. Park briefly while watching for the sweeper
  4. Do not park in the zone during the posted hours Correct answer.

Explanation

The sign prohibits parking during the stated window, and the plate explains the reason. Arriving inside that window means the restriction is in force. Hazard lights or a short stay do not create an exception.

Question 33Regulatory Signs (speed limits, stop/yield, lane use, turning and parking controls)

A white sign reading 'NO STANDING' is posted along a curb. How does this differ from a no-parking restriction?

  1. You may stop only between 9 AM and 5 PM
  2. You may stop to load or unload passengers but may not leave the vehicle parked Correct answer.
  3. You may park if you remain within sight of the vehicle
  4. You may not stop even momentarily to load passengers

Explanation

'NO STANDING' prohibits vehicles from waiting at the curb, but it still allows a brief stop to pick up or drop off passengers. It is stricter than no parking, which allows temporary stopping. It does not permit leaving the vehicle unattended.

Question 34Regulatory Signs (speed limits, stop/yield, lane use, turning and parking controls)

A white sign reads 'LEFT LANE MUST TURN LEFT.' You are in that lane but want to continue straight. What must you do?

  1. Stop in the lane and wait for a gap
  2. Change to a lane designated for through travel before the intersection Correct answer.
  3. Signal right and proceed straight anyway
  4. Continue straight from the left lane

Explanation

A mandatory-turn lane sign requires every vehicle in that lane to make the indicated turn. A driver who intends to go straight must move to a through lane beforehand. Remaining in the lane and proceeding straight would violate the sign.

Question 35Regulatory Signs (speed limits, stop/yield, lane use, turning and parking controls)

On an Oregon road with no posted limit, what maximum speed does state law generally set for an unpaved road in a rural area outside a business or residential district?

  1. 35 mph
  2. 25 mph
  3. 45 mph
  4. 55 mph Correct answer.

Explanation

Oregon's statutory speed limits set a general maximum of 55 mph on open rural highways when no limit is posted. Unpaved roads are not automatically reduced below that figure by state law alone. Drivers must still slow for conditions.

Question 36Regulatory Signs (speed limits, stop/yield, lane use, turning and parking controls)

A white sign reading 'ONE WAY' with an arrow pointing left is mounted at an intersection. What does it tell a driver approaching from that direction?

  1. Left turns are prohibited from your approach
  2. The street ahead is closed to through traffic
  3. Traffic on the cross street moves only to the left Correct answer.
  4. You must turn left at the intersection

Explanation

A ONE WAY sign describes the direction of travel on the street it faces. The arrow indicates that traffic on that roadway flows only in the arrow's direction. It does not itself order the approaching driver to turn.

Question 37Regulatory Signs (speed limits, stop/yield, lane use, turning and parking controls)

A white sign reading 'DO NOT ENTER' faces you at a roadway. What does it indicate about that roadway?

  1. It is closed only during rush hours
  2. It is reserved for buses and emergency vehicles
  3. It is a one-way street moving toward you
  4. It is a one-way street moving away from you Correct answer.

Explanation

'DO NOT ENTER' marks the wrong end of a one-way roadway, where traffic flows away from the sign's face. Entering there would put you against the flow of traffic. The sign is not a time-based or vehicle-class restriction.

Question 38Regulatory Signs (speed limits, stop/yield, lane use, turning and parking controls)

You approach an intersection where a white sign reads 'STOP' and, below it, 'ALL WAY.' What does the plate tell you?

  1. The stop applies only to trucks and buses
  2. Traffic from every approach must stop Correct answer.
  3. You may roll through when no traffic is present
  4. Only the street you are on has a stop requirement

Explanation

An 'ALL WAY' plate under a stop sign indicates that every approach at the intersection is controlled by a stop sign. Drivers still must stop fully, then proceed in turn. The plate does not relax the stop requirement.

Question 39Regulatory Signs (speed limits, stop/yield, lane use, turning and parking controls)

A white sign reading 'NO PARKING' is posted beside a curb marked with a blue painted line in Oregon. What does the blue curb indicate?

  1. Parking for persons with disabilities, with a permit required Correct answer.
  2. A fire hydrant zone with no stopping
  3. A loading zone for commercial trucks
  4. A bus stop with a scheduled layover

Explanation

Oregon uses blue curb paint to mark parking reserved for persons with disabilities who display a valid permit. Parking there without a permit is a violation even if a space appears open. The paint supplements the required signage.

Question 40Regulatory Signs (speed limits, stop/yield, lane use, turning and parking controls)

A sign shows a red circle with a diagonal slash over a symbol of a truck. What does this regulatory sign convey?

  1. Trucks must reduce speed on the roadway
  2. Trucks must yield to passenger vehicles there
  3. Trucks are required to use that route
  4. Trucks are prohibited from the posted roadway Correct answer.

Explanation

A red circle with a diagonal slash is the universal prohibition symbol. Applied to a truck symbol, it bans trucks from the roadway or zone where the sign is posted. It does not impose a speed or yield requirement.

Question 41Regulatory Signs (speed limits, stop/yield, lane use, turning and parking controls)

You are driving in a lane marked with a white diamond symbol and the word 'HOV' on a sign overhead. What does Oregon require to use that lane during posted hours?

  1. Any vehicle may use it if traffic is light
  2. The vehicle must be a commercial truck
  3. The vehicle must carry the stated number of occupants or qualify as exempt Correct answer.
  4. The vehicle must exit within one mile

Explanation

High-occupancy vehicle lanes are reserved during posted hours for vehicles carrying the required number of people or meeting an exemption such as a qualifying clean-fuel permit. A solo driver may not use the lane simply because traffic is light. The lane does not require a commercial vehicle classification or a short exit.

Question 42Regulatory Signs (speed limits, stop/yield, lane use, turning and parking controls)

A white sign reading 'RIGHT LANE MUST TURN RIGHT' is posted before an intersection, and you intend to go straight. What is the safest legal action?

  1. Stay in the right lane and continue straight
  2. Stop in the right lane and wait for a gap
  3. Turn right and make a U-turn afterward
  4. Move to a through lane before the intersection Correct answer.

Explanation

The sign makes the right lane a mandatory right-turn lane, so through traffic must leave it before the intersection. Changing lanes early keeps the turn lane clear and complies with the sign. Continuing straight from that lane would violate the posting.

Question 43Regulatory Signs (speed limits, stop/yield, lane use, turning and parking controls)

An Oregon sign reading 'NO PARKING 6 PM TO 6 AM' appears in a residential area. A driver parks there at 7 PM facing the posted direction. What is the status of that parking?

  1. Permitted, because overnight parking is always allowed
  2. Prohibited, because the time falls within the posted restriction Correct answer.
  3. Prohibited only if the vehicle blocks a driveway
  4. Permitted, because the restriction applies only to commercial vehicles

Explanation

The sign prohibits parking during the stated overnight window regardless of vehicle type. Parking at 7 PM falls inside that window and is therefore a violation. Blocking a driveway is a separate concern and does not define this restriction.

Question 44Regulatory Signs (speed limits, stop/yield, lane use, turning and parking controls)

A white sign reading 'SPEED LIMIT 20' is posted within a marked school speed zone, with a plate reading 'WHEN FLASHING.' The yellow lights are off and school is not in session. What does the sign require?

  1. The 20 mph limit applies only during winter months
  2. The 20 mph limit applies only to school buses
  3. The 20 mph limit applies at all times
  4. The 20 mph limit applies only when the lights flash Correct answer.

Explanation

A 'WHEN FLASHING' plate ties the reduced limit to the flashing signal, which is used during student arrival and dismissal periods. When the lights are off, the limit reverts to the normally posted speed. The reduced limit is not year-round or bus-only.

Question 45Warning Signs (curves, intersections, road narrowing, hills, surface conditions)

An Oregon driver approaches a yellow diamond sign showing a black arrow that bends sharply to the right. What hazard does this sign warn of?

  1. A merging lane from the right
  2. A right-turn-only lane ending
  3. A right lane closed ahead
  4. A sharp curve to the right ahead Correct answer.

Explanation

A yellow diamond with a single arrow curving in one direction is a curve warning sign; the arrow shows the direction the road bends, so a right-bending arrow means a sharp right curve. Warning signs are yellow diamonds because yellow signals a change in conditions ahead.

Question 46Warning Signs (curves, intersections, road narrowing, hills, surface conditions)

What does a yellow diamond sign displaying a black arrow that curves right and then left (an S-shape) indicate?

  1. A series of right turns only
  2. A divided highway ending
  3. A winding road beginning with a right curve Correct answer.
  4. A right lane merge area

Explanation

The reverse-curve (winding road) sign shows an arrow that bends one way then the other, warning of two or more curves in succession. The first bend in the symbol matches the first curve the driver meets.

Question 47Warning Signs (curves, intersections, road narrowing, hills, surface conditions)

A yellow diamond shows a black arrow bending left with a small speed plate reading 25 MPH mounted below it. What does the advisory speed mean?

  1. The speed limit that applies only to trucks
  2. The maximum safe speed for the curve under good conditions Correct answer.
  3. The legal minimum speed through the curve
  4. The speed at which the curve becomes a passing zone

Explanation

An advisory speed plate on a warning sign states the speed judged comfortable and safe for the hazard in good conditions. It is a recommendation rather than an absolute posted limit, but exceeding it in poor weather is unsafe.

Question 48Warning Signs (curves, intersections, road narrowing, hills, surface conditions)

You see a yellow diamond with a black cross symbol (a plus sign) on an Oregon rural road. What should you expect?

  1. A hospital zone ahead
  2. A church parking area ahead
  3. A four-way intersection ahead Correct answer.

Question 49Warning Signs (curves, intersections, road narrowing, hills, surface conditions)

A yellow diamond shows a black symbol of a road narrowing on both sides. What does this sign tell you?

  1. The pavement ends and becomes gravel
  2. A bridge weight limit is approaching
  3. The shoulder is now open to bicycles
  4. The roadway ahead is narrower than the current road Correct answer.

Explanation

The road-narrows sign warns that the traveled way ahead is reduced in width, so drivers should be prepared to adjust speed and lane position. It does not indicate a surface change or a weight restriction.

Question 50Warning Signs (curves, intersections, road narrowing, hills, surface conditions)

A yellow diamond sign shows a black truck on a downhill slope. What is the primary concern this sign raises for a driver?

  1. A truck-only lane beginning ahead
  2. A loading zone on the shoulder
  3. A steep downgrade where heavy vehicles may lose control or brake fade Correct answer.
  4. A weigh station requiring all vehicles to stop

Explanation

The hill sign with a downward slope warns of a steep grade ahead. On long downgrades, heavy trucks can build speed and experience brake fade, so other drivers should give them room and avoid cutting in front.
