Question 1Traffic Signs and Signals
A driver approaches an intersection where a steady red circular light is displayed and wants to make a right turn. What does North Dakota law allow, assuming no sign prohibits the turn?
- Slow to about 10 mph and turn right if the way is clear
- Come to a complete stop, yield to traffic and pedestrians, then turn right Correct answer.
- Stop only if other vehicles are present, then turn right
- Wait for a green arrow before turning right in any direction
Explanation
A steady red circular signal permits a right turn only after the driver makes a full stop and yields the right of way to pedestrians and approaching traffic. The turn is allowed unless a sign specifically prohibits it. Rolling slowly through the signal is not a legal substitute for the stop.
Question 2Traffic Signs and Signals
What is the meaning of a flashing yellow traffic signal at an intersection?
- Prepare to stop because the light is about to turn red
- Stop completely before entering the intersection
- Proceed with caution after yielding to cross traffic Correct answer.
- The signal is broken and the intersection is uncontrolled
Explanation
A flashing yellow light tells drivers to slow down and proceed carefully, yielding to any cross traffic or pedestrians already in the intersection. It does not require a stop. It also does not mean the signal is out of service.
Question 3Traffic Signs and Signals
How should a driver respond to a steady yellow circular light at an intersection?
- Speed up to clear the intersection before the red appears
- Stop if it is safe to do so; otherwise proceed through with caution Correct answer.
- Treat the light as a yield sign and merge with cross traffic
- Stop, then proceed through the intersection when it is clear
Explanation
A steady yellow light warns that the signal is about to turn red. The driver should stop if there is enough distance to do so safely, but if stopping would be abrupt or unsafe, the driver should continue through the intersection carefully.
Question 4Traffic Signs and Signals
A red X is displayed above a lane on an overhead freeway sign. What does this mean for drivers?
- The lane ahead is closed and must not be used Correct answer.
- The lane is reserved for high-occupancy vehicles only
- The lane is an exit-only lane that ends in one mile
- The lane may be used only when traffic is congested
Explanation
A red X over a lane means that lane is closed to traffic, often because of a crash, road work, or an incident ahead. Drivers should not enter or remain in that lane. A green arrow over a lane, by contrast, indicates the lane is open.
Question 5Traffic Signs and Signals
What shape and color identify a standard warning sign on North Dakota roads?
- A yellow diamond with black symbols or words Correct answer.
- A white rectangle with black lettering
- An orange pentagon with white lettering
- A green square with white lettering
Explanation
Warning signs alert drivers to upcoming hazards or changes in road conditions and are typically yellow diamonds with black legends. Their distinctive shape and color help drivers recognize them quickly. Orange is used for construction and green for guide information.
Question 6Traffic Signs and Signals
A driver sees a sign with a black letter "R" crossed by a red circle and diagonal slash. What does this sign indicate?
- Railroad crossing ahead
- Road work ahead
- No right turn Correct answer.
- Rest area closed
Explanation
A red circle with a diagonal slash is the universal prohibition symbol, and the letter inside identifies the prohibited action. An "R" with the slash therefore means no right turn. Railroad crossings use a round yellow sign with an X and RR.
Question 7Traffic Signs and Signals
What must a driver do when approaching a steady circular green light at an intersection?
- Proceed through the intersection but yield to vehicles and pedestrians lawfully in it Correct answer.
- Stop and wait for a green arrow before turning
- Yield to all vehicles on the cross street before proceeding
- Proceed only after sounding the horn to warn others
Explanation
A steady green light allows drivers to proceed straight or turn, but they must first yield to any vehicles, bicyclists, or pedestrians still lawfully within the intersection. A green light does not create an absolute right of way over traffic already there.
Question 8Traffic Signs and Signals
What does a pentagon-shaped sign with a white background and black lettering generally indicate?
- A railroad crossing ahead
- A school zone or school crossing Correct answer.
- A construction zone boundary
- A hospital emergency entrance
Explanation
The five-sided pentagon shape is reserved for school signs, warning drivers of a school zone or school crossing ahead. Drivers should slow down and watch for children. Other shapes, such as the round railroad advance sign, mark different hazards.
Question 9Traffic Signs and Signals
A driver approaches an intersection with a flashing red signal in all directions. How should the driver proceed?
- Slow down and continue without stopping if no traffic is present
- Wait for the signal to change to green before entering
- Treat it as a stop sign: stop, yield, then proceed when safe Correct answer.
- Yield only to vehicles approaching from the right
Explanation
A flashing red signal operates like a stop sign. The driver must come to a complete stop, yield to pedestrians and cross traffic, and then proceed when it is safe. Because all directions may flash red, drivers should be prepared to take turns.
Question 10Traffic Signs and Signals
What action should a driver take when a traffic signal changes from green to a steady yellow arrow pointing left?
- Treat the yellow arrow as permission to turn left after yielding to oncoming traffic
- Clear the intersection if already in it; otherwise stop if safe, because the protected turn is ending Correct answer.
- Complete the left turn without slowing, because the arrow is still lit
- Stop immediately in the intersection if the arrow turns yellow
Explanation
A steady yellow arrow warns that the protected left-turn phase is ending and the signal will soon turn red. A driver already in the intersection should complete the turn, while one approaching should stop if it can be done safely.
Question 11Traffic Signs and Signals
A driver encounters a sign with a black diagonal slash across a yellow diamond symbol showing a car skidding. What does the slash add to the sign's meaning?
- The hazard ends here Correct answer.
- The hazard has been repaired
- The sign applies only to trucks
- The hazard applies only in wet weather
Explanation
A diagonal slash across a warning sign symbol indicates the end of the condition that was previously warned about. In this case, the slippery-road hazard has ended. Drivers may resume normal caution appropriate to conditions.
Question 12Traffic Signs and Signals
What is the primary purpose of an orange sign in a work zone?
- To warn drivers of construction or maintenance activity ahead Correct answer.
- To mark a school crossing during construction season
- To provide directions to nearby services
- To indicate a mandatory speed reduction with legal force
Explanation
Orange signs are used in construction and maintenance zones to alert drivers to changed conditions, workers, and equipment. Drivers should slow down and be prepared for lane shifts or stops. Orange is the standard color for temporary work zone warnings.
Question 13Traffic Signs and Signals
A driver sees a circular yellow sign bearing a black "X" and the letters "RR." What should the driver expect?
- A crossing where trains have the right of way only during daylight
- A railroad yard where switching occurs without warning devices
- A railroad crossing ahead; slow down and be prepared to stop if a train approaches Correct answer.
- A railroad crossing ahead, requiring a stop before crossing
Explanation
The round yellow advance railroad warning sign tells drivers a crossing is ahead. Drivers should slow down sufficiently to look and listen for trains and be ready to stop if one is approaching. A stop is not required when no train is present.
Question 14Traffic Signs and Signals
A driver approaches an intersection where a green arrow points straight up while the circular signal is red. What does the green arrow permit?
- Proceed straight only, because the arrow gives a protected right of way Correct answer.
- Wait for the circular signal to turn green before moving
- Proceed straight or turn right, because the arrow applies to all movements
- Proceed straight only after yielding to cross traffic
Explanation
A green arrow permits movement only in the direction the arrow points and provides a protected right of way for that movement. Because the circular signal is red, other movements must wait. The arrow overrides the red for the indicated direction.
Question 15Traffic Signs and Signals
What does a white rectangular sign with black lettering reading "ONE WAY" with a right-pointing arrow indicate?
- Traffic on that street moves only to the right Correct answer.
- The right lane is reserved for right turns
- Traffic must merge right because the left lane ends
- Traffic may turn right only at the next intersection
Explanation
The ONE WAY sign indicates that all traffic on that roadway travels in the direction of the arrow. Drivers must not enter against the arrow. It is a regulatory sign, not a lane-use or turn instruction.
Question 16Traffic Signs and Signals
A driver sees a sign reading "STOP" on a school bus that has its red lights flashing and stop arm extended. What is the driver required to do on a two-lane road without a median?
- Stop and remain stopped until the red lights stop flashing Correct answer.
- Stop only if children are visible near the roadway
- Slow to 20 mph and pass carefully
- Continue if traveling in the opposite direction from the bus
Explanation
When a school bus displays flashing red lights and an extended stop arm, drivers approaching from either direction on an undivided road must stop and remain stopped until the lights are turned off. Passing the bus during this time is prohibited.
Question 17Traffic Signs and Signals
What does a sign with a red circle and slash over a black "U" and arrow indicate?
- Sharp curve requiring a U-shaped path
- No U-turn permitted Correct answer.
- U-turn area ahead
- Undivided highway begins
Explanation
The red circle with a slash is the prohibition symbol, and the U-shaped arrow indicates a U-turn. Together they mean U-turns are not allowed at that location. The sign is regulatory and enforceable.
Question 18Traffic Signs and Signals
A driver approaches a yield sign at the entrance to a freeway on-ramp. What is the correct action?
- Stop only if a vehicle is directly behind the driver
- Accelerate to match traffic and merge without checking
- Come to a complete stop before merging
- Slow down and merge only when there is a safe gap in traffic Correct answer.
Explanation
A yield sign requires the driver to slow down and give the right of way to traffic on the roadway being entered, merging only when a safe gap exists. A full stop is required only when necessary to yield safely.
Question 19Traffic Signs and Signals
A four-way stop intersection has vehicles arriving at about the same time from all four directions. Which vehicle has the right of way?
- The vehicle making a left turn
- The vehicle on the right Correct answer.
- The vehicle traveling fastest
- The vehicle that arrived last
Explanation
At a four-way stop where vehicles arrive at approximately the same time, the driver on the left must yield to the driver on the right. If the arrival times differ clearly, the first vehicle to stop and proceed has the right of way.
Question 20Traffic Signs and Signals
A driver is in a lane marked with a white diamond symbol. What does this marking indicate?
- The lane is reserved for high-occupancy vehicles or other special use Correct answer.
- The lane is a bicycle lane only
- The lane leads to a toll plaza
- The lane is closed ahead for construction
Explanation
A white diamond pavement marking designates a high-occupancy vehicle lane or another specially reserved lane. Drivers should check accompanying signs for occupancy requirements and hours of operation before using the lane.
Question 21Traffic Signs and Signals
A driver approaches an intersection where a police officer is directing traffic with hand signals that conflict with a green light. Whose direction should the driver follow?
- The traffic signal, because it is an official device
- The pedestrian signal, because it indicates safe crossing
- The police officer, because an officer's direction overrides the signal Correct answer.
- The vehicle in front, because it has already entered
Explanation
Directions given by a police officer or authorized flagger take precedence over traffic signals and signs. Drivers must obey the officer even when the signal indicates otherwise. This rule allows safe management of crashes, special events, and signal failures.
Question 22Traffic Signs and Signals
A driver sees a steady green light but the intersection ahead is blocked by queued traffic. What should the driver do?
- Enter and stop in the middle of the intersection until traffic moves
- Sound the horn and proceed through the queue
- Stay behind the stop line until there is room to clear the intersection Correct answer.
- Enter the intersection and wait in the crosswalk area
Explanation
Even on a green light, a driver should not enter an intersection unless there is enough space to clear it. Blocking the intersection can obstruct cross traffic and pedestrians. The driver should wait behind the stop line until space opens.
Question 23Traffic Signs and Signals
A driver approaches a flashing yellow arrow for a left turn while the circular signal is green. What does the flashing yellow arrow mean?
- The left turn is protected and oncoming traffic is stopped
- The driver must stop and wait for a green arrow
- Left turns are permitted after yielding to oncoming traffic and pedestrians Correct answer.
- Left turns are prohibited until the arrow turns green
Explanation
A flashing yellow left-turn arrow is a permissive signal: the driver may turn left but must yield to oncoming traffic and pedestrians. It is often used when the protected left-turn phase has ended. A green arrow, by contrast, provides a protected turn.
Question 24Traffic Signs and Signals
A driver sees a yellow diamond sign showing a traffic signal symbol. What does this sign warn of?
- A traffic signal is ahead that may not be visible until the driver is close Correct answer.
- A traffic signal is out of service and the intersection is uncontrolled
- A traffic signal will turn red if the driver exceeds the speed limit
- A traffic signal is being installed and will begin operating next year
Explanation
The signal-ahead warning sign alerts drivers that a traffic signal is approaching, often where sight distance is limited or where drivers may not expect one. Drivers should slow down and prepare to stop if the signal is red.
Question 25Traffic Signs and Signals
A driver approaches a railroad crossing with flashing red lights but no gate, and a train is not visible. What is the correct action?
- Stop, look and listen, and proceed only when the lights stop flashing and the way is clear Correct answer.
- Stop only if a vehicle ahead also stops
- Proceed across the tracks after slowing to 15 mph
- Drive around the lights if no train is in sight
Explanation
Flashing red lights at a railroad crossing mean a train is approaching, even if it is not yet visible. The driver must stop and remain stopped until the lights stop flashing and the crossing is clear. Proceeding against active warning lights is dangerous and illegal.
Question 26Traffic Signs and Signals
A driver sees a yellow diamond sign showing a pedestrian walking figure. What does this sign tell the driver?
- Pedestrians are prohibited from the roadway ahead
- The road ahead is closed to all vehicle traffic
- A pedestrian crossing is ahead, so the driver should slow down and watch for people in or near the roadway Correct answer.
- A pedestrian has the right of way at every intersection in the area
Explanation
Yellow diamond signs are warning signs, so a pedestrian symbol warns that a crossing or pedestrian activity is ahead. The driver should reduce speed and scan for people who may enter the roadway. The sign does not change right-of-way rules at other intersections.
Question 27Traffic Signs and Signals
A driver approaches a sign with a white background and a black curved arrow pointing left, with a smaller arrow branching off. What should the driver expect?
- Traffic will be required to turn left at the next intersection
- A left-turn lane begins immediately after the sign
- The main road curves left and a side road or lane branches to the left within the curve Correct answer.
- The left lane will end and merge into the right lane
Explanation
This is a curve warning with a side-road arrow, indicating the through road bends left while another road enters or exits within the curve. Drivers should slow before the curve and watch for vehicles entering or leaving. It is a warning of geometry, not a mandatory turn.
Question 28Traffic Signs and Signals
A driver sees a red circle with a diagonal slash over a black left-turn arrow on a white background. What does this sign mean?
- Left turns are prohibited at this location Correct answer.
- Left turns are permitted only during green arrows
- A left-turn lane is ahead but currently closed
- Drivers must turn left at the next intersection
Explanation
A red circle with a diagonal slash is the universal prohibition symbol, and here it covers a left-turn arrow. The combination means left turns are not allowed. Signal-controlled turn permissions are conveyed by the signal itself, not by a prohibition sign.
Question 29Traffic Signs and Signals
A driver is traveling on a two-lane road and sees a solid yellow line on their side of the centerline. What does this marking mean?
- The lane is reserved for high-occupancy vehicles
- Passing is permitted whenever the road ahead is clear
- Passing is prohibited on their side, though turning across the line may be allowed Correct answer.
- Traffic on both sides may pass freely
Explanation
A solid yellow centerline on the driver's side forbids passing because sight distance or roadway conditions make it unsafe. Drivers may still cross the line when making a legal left turn into a driveway or side road. A broken yellow line would indicate passing is permitted when safe.
Question 30Traffic Signs and Signals
A driver sees a white rectangular sign with black lettering that reads "SPEED LIMIT 45." What does this sign establish?
- The speed limit is 45 mph only during daytime hours
- The minimum lawful speed is 45 mph
- The maximum lawful speed under normal conditions is 45 mph Correct answer.
- The recommended speed for the curve ahead is 45 mph
Explanation
A white regulatory sign with black numerals states the maximum legal speed under favorable conditions. Drivers must still slow below that limit when weather, traffic, or visibility require it. Advisory speeds for curves appear on yellow warning signs instead.
Question 31Traffic Signs and Signals
A driver approaches a signal displaying a steady red arrow pointing right. What must the driver do?
- Stop and remain stopped for the movement indicated by the arrow until it changes Correct answer.
- Yield and turn right if the way is clear
- Proceed with caution because arrows are advisory only
- Treat the red arrow as a flashing yellow arrow
Explanation
A steady red arrow is a stop signal for traffic moving in the direction the arrow points. The driver must wait until the arrow changes before making that movement. A right turn on red may be allowed only where permitted and after a full stop, but the arrow itself requires stopping.
Question 32Traffic Signs and Signals
A driver sees a yellow diamond sign with a symbol of a truck on a downhill grade and the word "TRUCKS." What is this sign warning about?
- Trucks must exit at the next ramp
- A truck weigh station is located ahead
- Trucks may be traveling slowly on the downgrade ahead Correct answer.
- Trucks are prohibited from using the road ahead
Explanation
Yellow warning signs with a truck on a grade alert drivers that heavy vehicles may be moving slowly downhill. Drivers should anticipate reduced speeds and avoid cutting in front of a truck that needs distance to stop. The sign does not restrict or redirect trucks.
Question 33Traffic Signs and Signals
A driver sees a circular sign with a white background and a red border containing the number "25." What does this sign indicate?
- The maximum safe speed for the upcoming condition is 25 mph Correct answer.
- The route number is 25
- The minimum speed on the road is 25 mph
- The distance to the next exit is 25 miles
Explanation
A white circle with a red border and black numerals is an advisory speed plaque, usually paired with a warning sign. It states the maximum speed considered safe for the curve, ramp, or hazard ahead. It is not a general regulatory speed limit.
Question 34Traffic Signs and Signals
A driver sees a sign reading "DO NOT PASS" with a black arrow curving to the left. What does this sign mean?
- The driver must not enter the left lane for any reason
- Passing is prohibited only for trucks
- The driver may not pass other vehicles in the zone ahead Correct answer.
- The driver must move to the left lane
Explanation
DO NOT PASS is a regulatory sign that forbids overtaking other vehicles in the posted zone, often because of limited sight distance. Drivers may still cross the centerline to make a legal turn. The restriction applies to all vehicles, not just trucks.
Question 35Traffic Signs and Signals
A driver approaches an intersection where a steady yellow light appears and cannot stop safely before the crosswalk. What should the driver do?
- Continue through the intersection and clear it promptly Correct answer.
- Accelerate well above the limit to beat the red
- Reverse to the stop line before the light turns red
- Stop abruptly in the intersection
Explanation
A steady yellow light warns that the signal is about to turn red and drivers should stop if they can do so safely. If stopping would require an abrupt or unsafe maneuver, the driver should proceed through and clear the intersection. Speeding up beyond the limit is never appropriate.
Question 36Traffic Signs and Signals
A driver sees a rectangular white sign with black lettering reading "KEEP RIGHT" beside a raised median. What does this sign require?
- Stop and wait for a right-turn arrow
- Merge right because the left lane ends
- Turn right at the next intersection
- Pass to the right side of the median or obstruction Correct answer.
Explanation
KEEP RIGHT is a regulatory sign directing traffic to pass on the right side of a median, island, or other obstruction. It describes the required path around a physical feature rather than a turn instruction. Drivers should position their vehicle accordingly before reaching the obstruction.
Question 37Traffic Signs and Signals
A driver sees a green arrow pointing left while the circular signal is red. What does the green arrow allow?
- No left turn until the circular light turns green
- A protected left turn, because conflicting traffic is held by red signals Correct answer.
- A left turn only after yielding to oncoming traffic
- A left turn only if the driver first stops completely
Explanation
A green arrow gives a protected movement, meaning opposing and conflicting traffic faces red signals. The driver may turn left without yielding to oncoming vehicles, though pedestrians in the crosswalk must still be respected. A plain green circle would require yielding to oncoming traffic.
Question 38Traffic Signs and Signals
A driver sees an orange diamond sign with the word "DETOUR" and an arrow pointing right. What should the driver do?
- Ignore the sign because orange signs are advisory
- Follow the marked alternate route to the right Correct answer.
- Turn right only if the driver's destination lies that way
- Stop and wait for a flagger before continuing
Explanation
Orange signs mark temporary traffic conditions in work zones, and DETOUR signs direct drivers onto an alternate route. The driver should follow the arrow to stay on the designated path around the closure. Orange signs carry regulatory force when they direct traffic.
Question 39Traffic Signs and Signals
A driver sees a yellow diamond sign showing a symbol of a car on a slippery, curving road surface. What should the driver do?
- Reduce speed and avoid sudden braking or steering inputs Correct answer.
- Increase speed to pass the slippery section quickly
- Maintain speed because the warning applies only in rain
- Shift into neutral to improve traction
Explanation
A slippery-when-wet warning sign alerts drivers that traction may be reduced on the road ahead. The safe response is to slow down before the hazard and make smooth, gradual control inputs. Sudden braking or steering can cause a skid on a low-traction surface.
Question 40Traffic Signs and Signals
A driver sees a white rectangular sign reading "YIELD HERE TO PEDESTRIANS" at a marked crosswalk. What does this sign require?
- Drivers must yield to pedestrians in the crosswalk at that point Correct answer.
- Pedestrians must yield to vehicles at that crosswalk
- Vehicles must stop only when a pedestrian is on the same half of the road
- Pedestrians are prohibited from crossing at that location
Explanation
This regulatory sign reminds drivers that pedestrians in the marked crosswalk have the right of way. Drivers should slow and be prepared to stop before the crosswalk. The sign does not prohibit pedestrians or shift the duty to yield onto them.
Question 41Traffic Signs and Signals
A driver approaches a flashing yellow signal at an intersection. What is the correct action?
- Stop completely and wait for a green light
- Accelerate to pass through before the signal changes
- Slow down, proceed with caution, and yield as required Correct answer.
- Stop only if another vehicle is already in the intersection
Explanation
A flashing yellow signal means proceed with caution after slowing to assess the intersection. Drivers must still obey right-of-way rules and yield to cross traffic or pedestrians as applicable. A full stop is required only for a flashing red signal.
Question 42Traffic Signs and Signals
A driver sees a yellow diamond sign showing a symbol of a bicycle. What does this sign indicate?
- The driver must ride a bicycle to use the lane
- A bicycle sales or rental business is ahead
- Bicycles are prohibited from the road ahead
- Bicyclists may be crossing or sharing the roadway ahead Correct answer.
Explanation
A bicycle warning sign alerts drivers that cyclists may enter or share the roadway ahead. Drivers should slow and give cyclists adequate space. The sign warns of a hazard rather than prohibiting bicycles.
Question 43Traffic Signs and Signals
A driver sees a sign with a red circle and slash over a symbol of a pedestrian. What does this sign mean?
- Pedestrians must use only the left side of the road
- Pedestrians have the right of way in the area
- Pedestrians are prohibited from entering the area Correct answer.
- A pedestrian crossing is located just ahead
Explanation
The red circle with a diagonal slash marks a prohibition, and here it forbids pedestrians from the area, such as a freeway shoulder or restricted zone. Drivers should not expect pedestrians there, but should remain alert. A pedestrian crossing warning would be a yellow diamond sign.
Question 44Traffic Signs and Signals
A driver sees a yellow diamond sign showing a symbol of a tractor and the word "FARM EQUIPMENT." What should the driver anticipate?
- A farm supply store is located ahead
- The road surface becomes gravel immediately
- Slow-moving farm vehicles may be on or crossing the road ahead Correct answer.
- Farm vehicles are banned from the road ahead
Explanation
Farm equipment warning signs alert drivers that slow-moving tractors or implements may be using or crossing the roadway. Drivers should reduce speed and be prepared to stop, especially near field entrances. The sign warns of a hazard rather than banning farm vehicles.
Question 45Traffic Signs and Signals
A driver sees a white rectangular sign with black lettering reading "NO TURN ON RED." What does this sign change about the driver's behavior?
- The driver may turn right on red only after yielding
- The driver may turn right on red only during daytime hours
- The driver must turn right when the signal is red
- The driver may not turn right after stopping when the signal is red Correct answer.
Explanation
NO TURN ON RED removes the usual permission to turn right after a full stop at a red signal. The driver must wait for a green indication before making the turn. The restriction applies at all hours unless a plaque states otherwise.
Question 46Traffic Signs and Signals
A driver sees a yellow diamond sign with a symbol of two arrows merging into one. What does this sign warn of?
- The road divides into two separate lanes
- A two-way road begins ahead
- Two lanes will merge into one ahead Correct answer.
- Traffic will be required to exit ahead
Explanation
A merge warning sign shows two lanes converging into a single lane. Drivers should prepare to adjust speed and position smoothly, yielding as needed to traffic in the continuing lane. A lane-split sign would show lanes diverging instead.
Question 47Traffic Signs and Signals
A driver sees a yellow diamond sign showing an arrow curving sharply to the right with the advisory plaque "35 MPH." What does the combination tell the driver?
- The legal speed limit on the entire road is 35 mph
- The minimum speed through the curve is 35 mph
- The curve can be taken safely at no more than about 35 mph under normal conditions Correct answer.
- The curve is 35 feet ahead
Explanation
The yellow warning sign identifies a sharp curve, and the advisory plaque gives the maximum speed considered safe for that curve. Drivers should slow to or below that speed before entering the curve. The advisory speed is not a general posted speed limit for the road.
Question 48Traffic Signs and Signals
A driver sees a white rectangular sign reading "LEFT LANE MUST TURN LEFT" above a lane. What does this sign require?
- Vehicles in that lane must turn left at the intersection Correct answer.
- Vehicles in that lane must merge right before the intersection
- Vehicles in that lane may continue straight if desired
- Vehicles in that lane must stop and wait for a green arrow
Explanation
This regulatory sign assigns a mandatory movement to the indicated lane, so vehicles in it must turn left. Drivers who intend to continue straight should change lanes before the intersection. The sign does not require waiting for a green arrow before entering the turn lane.
Question 49Traffic Signs and Signals
A driver sees a yellow diamond sign showing a symbol of a train on tracks with the letters "RR" on a circular yellow sign nearby. What does this combination warn of?
- A train station is ahead with a parking area
- A railroad crossing is ahead, and drivers should slow and prepare to stop if a train approaches Correct answer.
- A railroad yard is ahead and trains never cross the road
- The road crosses tracks only for pedestrians
Explanation
The advance railroad warning diamond and the circular railroad crossing symbol both alert drivers to tracks ahead. Drivers should slow, look both ways, and be ready to stop if a train is approaching. The signs warn of an active crossing rather than a station or pedestrian-only path.
Question 50Traffic Signs and Signals
A driver sees a white rectangular sign with black lettering reading "STOP HERE ON RED" at a signalized intersection. What does this sign require?
- Stop at the marked line before proceeding when the signal is red Correct answer.
- Stop and wait for a police officer before proceeding
- Stop at the sign only when turning right
- Stop only if a pedestrian is present
Explanation
This sign specifies where a driver must stop when facing a red signal, often to keep the crosswalk or intersection clear. The driver stops at the marked line and then proceeds only when permitted. It does not depend on pedestrian presence or the direction of the turn.
