Question 1Regulatory Signs (prohibitory and mandatory)

A white rectangular sign with black lettering reads "SPEED LIMIT 55." What does this sign establish for the roadway?

  1. The speed limit that applies only to trucks
  2. The maximum lawful speed under normal conditions Correct answer.
  3. A minimum speed that all traffic must maintain
  4. An advisory speed for curves only

Explanation

A white regulatory sign with black numerals states the maximum lawful speed for that roadway under normal conditions. Drivers may travel slower when conditions require, and the limit is not restricted to a single vehicle class.

Question 2Regulatory Signs (prohibitory and mandatory)

You approach a red and white sign reading "DO NOT ENTER." Under what circumstance may you proceed past it?

  1. Only when traffic is light
  2. Only if you are passing another vehicle
  3. Only during daylight hours
  4. Never, because it marks a one-way roadway coming toward you Correct answer.

Explanation

DO NOT ENTER marks a roadway where traffic moves toward you, so entering would put you in the path of oncoming vehicles. There is no condition of light traffic or time of day that makes entry lawful.

Question 3Regulatory Signs (prohibitory and mandatory)

A red octagonal sign requires you to come to a complete stop. What must you do before proceeding?

  1. Stop completely, then yield to traffic and pedestrians before going Correct answer.
  2. Sound your horn and roll through slowly
  3. Slow to about 10 mph and continue if clear
  4. Stop only if another vehicle is visible

Explanation

The octagonal STOP sign requires a full stop at the marked line or before entering the intersection. After stopping, the driver must yield the right of way to cross traffic and to pedestrians in the crosswalk.

Question 4Regulatory Signs (prohibitory and mandatory)

A red triangle sign with the point downward reading "YIELD" tells you to do what?

  1. Maintain speed because you have priority
  2. Slow down and give the right of way to traffic on the intersecting road Correct answer.
  3. Merge without checking for other vehicles
  4. Stop fully for three seconds

Explanation

A YIELD sign requires you to slow and let cross traffic and pedestrians go first, entering only when it is safe. A full stop is only necessary when traffic conditions make it necessary.

Question 5Regulatory Signs (prohibitory and mandatory)

A white rectangular sign with a red circle and a diagonal red slash over a symbol indicates what?

  1. A warning of a hazard ahead
  2. A construction zone requirement
  3. A prohibition of the depicted action Correct answer.
  4. A recommended action

Explanation

The red circle with a diagonal slash is the standard prohibition symbol, meaning the depicted maneuver or vehicle type is not allowed. Warning hazards are shown on yellow diamond signs instead.

Question 6Regulatory Signs (prohibitory and mandatory)

A rectangular white sign reads "ONE WAY" with an arrow. What does it tell you about the street?

  1. Traffic on that street moves only in the direction of the arrow Correct answer.
  2. The street carries two-way traffic with a passing lane
  3. The street is closed to all traffic
  4. Parking is allowed only in the arrow direction

Explanation

The ONE WAY sign designates the permitted direction of travel for that roadway. Entering against the arrow would mean driving into oncoming traffic.

Question 7Regulatory Signs (prohibitory and mandatory)

A white sign shows a red circle with a slash over a left-turn arrow. What does this mean for your route?

  1. You must turn left
  2. Left turns are prohibited at this location Correct answer.
  3. Left turns are allowed only for local traffic
  4. Left turns are permitted only during green lights

Explanation

A red circle and slash over a turn arrow prohibits that turn at the location. The sign communicates the restriction regardless of signal color.

Question 8Regulatory Signs (prohibitory and mandatory)

A white sign reads "NO PARKING ANY TIME." What does it require of you?

  1. You may park if you remain in the vehicle
  2. You may not leave a vehicle parked there at any hour Correct answer.
  3. You may park for up to 15 minutes
  4. You may park overnight only

Explanation

NO PARKING ANY TIME prohibits leaving a vehicle stopped at that location at all hours. Remaining in the vehicle does not convert parking into a permitted act.

Question 9Regulatory Signs (prohibitory and mandatory)

A white sign with black lettering reads "KEEP RIGHT." How should you respond when you see it?

  1. Turn right at the next intersection
  2. Stay in the right-hand lane or to the right of the divider Correct answer.
  3. Reduce speed and move to the shoulder
  4. Pass on the left side of the median or obstacle

Explanation

KEEP RIGHT directs traffic to remain on the right side of a median, island, or obstacle. It is a mandatory direction sign rather than a turn instruction.

Question 10Regulatory Signs (prohibitory and mandatory)

A white rectangular sign reads "SPEED LIMIT 65" and below it a smaller sign reads "TRUCKS 55." What is the lawful maximum for a passenger car?

  1. The lower of the two figures
  2. 65 mph Correct answer.
  3. 55 mph
  4. 60 mph

Explanation

The primary speed limit sign sets the maximum for general traffic, while the supplemental truck sign sets a lower limit for trucks. A passenger car is therefore bound by the 65 mph figure.

Question 11Regulatory Signs (prohibitory and mandatory)

You are driving and see a white sign reading "WRONG WAY." What should you do immediately?

  1. Reverse along the shoulder to the last intersection
  2. Stop, turn around when safe, and get back to the correct direction Correct answer.
  3. Flash your headlights and keep going
  4. Continue slowly to the next exit

Explanation

A WRONG WAY sign faces drivers who have entered a roadway against the intended flow, such as a one-way street or freeway ramp. The driver must stop, reverse direction safely, and re-enter the correct flow.

Question 12Regulatory Signs (prohibitory and mandatory)

A white sign reads "LEFT TURN ONLY" with a single left-pointing arrow. What does it require at the intersection?

  1. You must turn left from that lane Correct answer.
  2. You must yield before turning left only
  3. You may go straight or turn left
  4. Left turns are optional if the lane is clear

Explanation

A mandatory turn sign with a single arrow requires the driver in that lane to make the indicated turn. Proceeding straight would violate the lane's designated movement.

Question 13Regulatory Signs (prohibitory and mandatory)

A white sign shows a red circle with a slash over a pedestrian symbol. What does it convey?

  1. Pedestrians have the right of way here
  2. A pedestrian crossing is ahead
  3. Pedestrians must use the crosswalk
  4. Pedestrians are prohibited from this area Correct answer.

Explanation

A prohibition symbol over a pedestrian figure means pedestrians are not permitted in that area, such as certain tunnels or limited-access roadways. A crossing warning would use a yellow diamond instead.

Question 14Regulatory Signs (prohibitory and mandatory)

A white sign reads "NO U-TURN." When does this restriction apply?

  1. Only when a police officer is present
  2. Only during rush hour
  3. At all times at that location Correct answer.
  4. Only when school is in session

Explanation

A NO U-TURN sign is a standing regulatory restriction that applies continuously at that location. It is not tied to time of day, school schedules, or enforcement presence.

Question 15Regulatory Signs (prohibitory and mandatory)

A white sign reads "DO NOT PASS" with a symbol of two cars. What does it prohibit?

  1. Entering the roadway from a driveway
  2. Exceeding the posted speed limit
  3. Passing other vehicles in that zone Correct answer.
  4. Driving in the left lane at any time

Explanation

The DO NOT PASS sign establishes a no-passing zone where overtaking other vehicles is prohibited. It works with pavement markings to protect sight distance on that stretch.

Question 16Regulatory Signs (prohibitory and mandatory)

A white sign reads "RESERVED PARKING" with a wheelchair symbol. Who may legally use that space?

  1. Any driver during off-peak hours
  2. Any driver for up to 10 minutes
  3. Only vehicles carrying more than one person
  4. A driver displaying a valid disability permit or plate Correct answer.

Explanation

Accessible parking spaces are reserved for vehicles displaying a valid disability permit or license plate. Other drivers may not use the space even briefly.

Question 17Regulatory Signs (prohibitory and mandatory)

A white sign reads "RIGHT LANE MUST TURN RIGHT." What must a driver in that lane do?

  1. Change lanes to avoid turning
  2. Turn right at the intersection Correct answer.
  3. Continue straight if desired
  4. Stop and wait for a gap

Explanation

The sign designates the right lane as a mandatory turn lane, so vehicles in it must turn right. A driver who intends to continue straight should have moved to another lane earlier.

Question 18Regulatory Signs (prohibitory and mandatory)

A white sign reads "NO TRUCKS" with a symbol of a heavy vehicle. What does it mean for a driver of a large commercial truck?

  1. The truck is prohibited from that route Correct answer.
  2. The truck may proceed at reduced speed
  3. The truck must use the left lane
  4. The truck must obtain a permit at the next stop

Explanation

A NO TRUCKS sign excludes heavy commercial vehicles from the designated roadway. Such drivers must use an alternate route rather than proceeding at a reduced speed.

Question 19Regulatory Signs (prohibitory and mandatory)

A white sign reads "STOP HERE ON RED" beside a marked stop line. What does it require at a red signal?

  1. Stop at the line and wait for a green light before proceeding Correct answer.
  2. Stop past the line to improve visibility
  3. Stop only if a vehicle is approaching
  4. Stop at the line, then proceed if clear without waiting

Explanation

The sign reinforces the placement of the stop line at a signalized intersection. A red light requires a stop at that line and waiting until the signal permits movement.

Question 20Regulatory Signs (prohibitory and mandatory)

A white sign reads "NO PARKING 8 AM TO 4 PM." A driver arrives at 5 PM. What does the sign allow?

  1. Parking is prohibited until midnight
  2. Parking is permitted because the restriction has ended for the day Correct answer.
  3. Parking is permitted for only 30 minutes
  4. Parking is prohibited because the sign applies all day

Explanation

A time-qualified parking sign restricts parking only during the stated hours. Outside that window, the posted prohibition no longer applies, subject to any other signs at the location.

Question 21Regulatory Signs (prohibitory and mandatory)

A white sign reads "LEFT LANE MUST TURN LEFT" on a three-lane road. A driver in the left lane wants to continue straight. What is the correct action?

  1. Move right into a through lane before the intersection Correct answer.
  2. Turn left as the lane requires
  3. Stop in the lane and wait for a gap
  4. Continue straight from the left lane

Explanation

The mandatory sign assigns the left lane exclusively to left turns. A driver intending to go straight must change to a through lane before reaching the intersection rather than forcing a turn.

Question 22Regulatory Signs (prohibitory and mandatory)

A white sign reads "NO PEDESTRIANS, BICYCLES, OR MOTOR-DRIVEN CYCLES" at a tunnel entrance. How should this be interpreted?

  1. Only pedestrians are excluded from the tunnel
  2. All three listed user types are prohibited from the tunnel Correct answer.
  3. The restriction applies only to motor-driven cycles
  4. Bicycles may enter if ridden on the shoulder

Explanation

A sign listing multiple excluded users bars each of the named categories from the facility. The listed groups are joined by the prohibition rather than limited to only one of them.

Question 23Regulatory Signs (prohibitory and mandatory)

A white sign reads "RIGHT TURN ON RED PROHIBITED." A driver is stopped at a red light and wishes to turn right. What is required?

  1. Turn right only after yielding to pedestrians
  2. Stop, then turn right if the way is clear
  3. Turn right after sounding the horn
  4. Wait for a green light before turning right Correct answer.

Explanation

The sign removes the usual permission to turn right after stopping at a red light. The driver must remain stopped until the signal turns green, regardless of whether the way appears clear.

Question 24Regulatory Signs (prohibitory and mandatory)

A white sign reads "VEHICLES OVER 4 TONS PROHIBITED" on a bridge approach. A driver of a 6-ton truck sees the sign. What is the correct course of action?

  1. Cross only if no other vehicles are on the bridge
  2. Use an alternate route that avoids the bridge Correct answer.
  3. Cross the bridge at reduced speed
  4. Stop and wait for permission from other drivers

Explanation

A weight-restricted sign bars vehicles exceeding the stated limit from the structure. A driver whose vehicle exceeds the threshold must find another route rather than attempting the crossing.

Question 25Regulatory Signs (prohibitory and mandatory)

A white sign reads "NO LEFT TURN 7 AM TO 9 AM AND 4 PM TO 6 PM." A driver approaches at 10 AM and wants to turn left. What does the sign permit?

  1. A left turn only if traffic is light
  2. No left turn, because the sign restricts the whole day
  3. A left turn, because 10 AM falls outside both restricted periods Correct answer.
  4. No left turn, because the morning period extends to noon

Explanation

The sign limits the left-turn ban to two stated peak windows. At 10 AM, neither window is active, so the turn is permitted if other rules allow it.

Question 26Regulatory Signs (prohibitory and mandatory)

A white rectangular sign with black lettering reads "DO NOT ENTER." What does this sign mean for your vehicle?

  1. You may proceed only after stopping completely.
  2. You may enter but must yield to oncoming traffic.
  3. You must not drive past the sign into that roadway. Correct answer.
  4. You may enter only if you are turning right.

Explanation

A DO NOT ENTER sign marks a roadway where traffic is not permitted to proceed in your direction, often the exit ramp of a one-way street or a divided highway. You must not drive past it, because doing so puts you against the intended flow of traffic.

Question 27Regulatory Signs (prohibitory and mandatory)

A white sign displays a red circle with a diagonal slash over a symbol of a bicycle. What does this regulatory sign indicate?

  1. Bicycles must yield to motor vehicles.
  2. A bicycle lane begins ahead.
  3. Bicycles must use the shoulder.
  4. Bicycles are prohibited from this area. Correct answer.

Explanation

A red circle with a slash is the standard prohibition symbol, and when placed over a bicycle it means bicyclists are not allowed in the designated area. The sign is regulatory, so riding a bicycle past it would violate the restriction.

Question 28Regulatory Signs (prohibitory and mandatory)

A white sign with black lettering reads "YIELD" and is placed at an intersection. What action does this regulatory sign require?

  1. Maintain your speed because you have the right of way.
  2. Come to a complete stop before entering the intersection.
  3. Stop only if a vehicle is physically present in the intersection.
  4. Slow down and be prepared to stop for traffic already in or approaching the intersection. Correct answer.

Explanation

A YIELD sign requires you to slow down and give the right of way to vehicles and pedestrians already in or approaching the intersection. You need not stop unless traffic conditions require it, but you must be ready to stop.

Question 29Regulatory Signs (prohibitory and mandatory)

A white rectangular sign reads "NO PARKING" with no times or days listed. What does this sign mean?

  1. Parking is prohibited at all times. Correct answer.
  2. Parking is allowed for up to 30 minutes.
  3. Parking is allowed if you remain with the vehicle.
  4. Parking is prohibited only during business hours.

Explanation

When a NO PARKING sign does not list days or hours, the restriction applies at all times. Leaving your vehicle stopped there, even briefly, is a parking violation.

Question 30Regulatory Signs (prohibitory and mandatory)

A white sign with black lettering reads "KEEP RIGHT OF MEDIAN." How should you interpret this sign?

  1. You must turn right at the next intersection.
  2. You may drive on either side of the median.
  3. You must merge right because your lane ends.
  4. You must keep your vehicle to the right side of the raised median. Correct answer.

Explanation

KEEP RIGHT OF MEDIAN directs traffic to pass on the right side of a raised or painted median. Driving to the left of the median would put you in opposing traffic or a prohibited area.

Question 31Regulatory Signs (prohibitory and mandatory)

A white sign reads "NO RIGHT TURN ON RED." You are stopped at a red light and want to turn right. What does the sign require?

  1. You may turn right if no pedestrians are present.
  2. You must wait for a green light before turning right. Correct answer.
  3. You may turn right only after coming to a complete stop.
  4. You may turn right after yielding to traffic.

Explanation

A NO RIGHT TURN ON RED sign removes the usual permission to turn right after stopping at a red light. You must remain stopped until the signal turns green, regardless of traffic conditions.

Question 32Regulatory Signs (prohibitory and mandatory)

A white sign reads "NO PARKING 8 AM TO 4 PM." You arrive at 5 PM and want to park. What does the sign allow?

  1. Parking is prohibited at all times.
  2. Parking is prohibited until 8 AM the next day.
  3. Parking is allowed because the restriction has ended for the day. Correct answer.
  4. Parking is allowed only for loading or unloading.

Explanation

The sign limits the no-parking rule to the hours between 8 AM and 4 PM. Outside that window, the restriction does not apply, so parking at 5 PM is permitted unless another sign or rule says otherwise.

Question 33Regulatory Signs (prohibitory and mandatory)

A white sign reads "ONE WAY" with an arrow pointing left. You are facing the sign at an intersection. What does it tell you about the street to your left?

  1. The street is closed to all traffic.
  2. Traffic on that street moves only toward you.
  3. The street is for buses only.
  4. Traffic on that street moves only away from you to the left. Correct answer.

Explanation

The ONE WAY sign with a left-pointing arrow means traffic on that street travels only in the direction the arrow points, which is to the left and away from your position. You may enter and travel in that direction, but you must not drive against it.

Question 34Regulatory Signs (prohibitory and mandatory)

A white sign reads "TRUCKS USE LOW GEAR" on a steep downgrade. What does this sign direct a truck driver to do?

  1. Reduce speed only if the grade is icy.
  2. Shift to a lower gear before descending the grade. Correct answer.
  3. Use the left lane for the descent.
  4. Stop and wait for a pilot car.

Explanation

The sign advises truck drivers to select a low gear before starting down a steep grade so engine braking helps control speed and prevents brake fade. Selecting the gear before the descent is safer than shifting after the grade begins.

Question 35Regulatory Signs (prohibitory and mandatory)

A white sign reads "NO LEFT TURN 7 AM TO 9 AM AND 4 PM TO 6 PM." You approach at 10 AM and want to turn left. What does the sign allow?

  1. The left turn is prohibited at all times.
  2. The left turn is prohibited until 6 PM.
  3. The left turn is allowed because 10 AM is outside the listed hours. Correct answer.
  4. The left turn is allowed only if you use a turn signal.

Explanation

The sign prohibits left turns only during the two listed time windows. At 10 AM, neither window is active, so the left turn is permitted unless another restriction applies.

Question 36Regulatory Signs (prohibitory and mandatory)

A white sign reads "VEHICLES OVER 4 TONS PROHIBITED" at a bridge approach. You are driving a 6-ton truck. What must you do?

  1. Do not cross the bridge; choose another route. Correct answer.
  2. Proceed because the sign applies only to commercial vehicles.
  3. Proceed slowly to reduce stress on the bridge.
  4. Cross only if no other vehicle is on the bridge.

Explanation

The sign sets a weight limit of 4 tons, and a 6-ton truck exceeds it. The restriction is absolute, so the driver must not cross the bridge and should find an alternate route.

Question 37Regulatory Signs (prohibitory and mandatory)

A white sign reads "STOP HERE ON RED" beside a marked stop line. What does it require when the signal is red?

  1. Stop after entering the intersection.
  2. Stop only if a vehicle is approaching.
  3. Stop at the marked stop line, not beyond it. Correct answer.
  4. Stop at the sign, even if the stop line is farther ahead.

Explanation

The sign directs drivers to stop at the marked stop line when the signal is red. Stopping beyond the line can intrude into the crosswalk or intersection and is a violation.

Question 38Regulatory Signs (prohibitory and mandatory)

A white sign reads "LEFT LANE MUST TURN LEFT" on a three-lane road. You are in the left lane but want to continue straight. What is the proper action?

  1. Continue straight because the sign is only a suggestion.
  2. Continue straight while signaling to indicate your intention.
  3. Stop in the left lane and wait for a gap to merge.
  4. Turn left as the sign requires, or change lanes earlier to avoid the left lane. Correct answer.

Explanation

A mandatory lane sign requires drivers in that lane to make the indicated movement. If you want to go straight, you must move out of the left lane before reaching the intersection; once in the lane, you must turn left.

Question 39Regulatory Signs (prohibitory and mandatory)

A white sign shows a red circle with a slash over a U-turn arrow, and below it a smaller sign reads "EXCEPT EMERGENCY VEHICLES." What does this combination mean for an ordinary driver?

  1. U-turns are allowed only during daytime hours.
  2. U-turns are prohibited for all drivers at all times.
  3. U-turns are prohibited for ordinary drivers, but authorized emergency vehicles are exempt. Correct answer.
  4. U-turns are allowed for ordinary drivers when traffic is light.

Explanation

The prohibition symbol bans U-turns, and the exception plaque limits that ban by allowing the listed emergency vehicles to make them. An ordinary driver remains prohibited regardless of traffic or time of day.

Question 40Regulatory Signs (prohibitory and mandatory)

A white rectangular sign with black lettering reads "SPEED LIMIT 55" on a rural Minnesota highway. What does this sign establish for your vehicle?

  1. A speed that applies only to trucks and buses, not passenger cars
  2. A minimum speed that all vehicles must maintain or be cited
  3. A recommended speed that you may exceed when traffic is light
  4. The maximum lawful speed in good conditions, not a required speed to maintain Correct answer.

Explanation

A white speed limit sign with black numerals is a regulatory sign that sets the maximum lawful speed for that stretch of road when conditions are favorable. It is a ceiling, not a target, and drivers must slow below it when weather, visibility, or traffic require. The number applies to all vehicles unless a separate sign states otherwise.

Question 41Warning Signs and Roadway Alignment

A yellow diamond sign showing a black symbol of a car with two wavy skid marks behind it warns a Minnesota driver approaching what condition?

  1. Loose gravel on the shoulder
  2. Slippery when wet pavement Correct answer.
  3. A steep downgrade ahead
  4. An upcoming sharp curve

Explanation

The yellow diamond with a car trailing wavy skid marks is the slippery-when-wet warning. It tells you the pavement loses traction in rain, snow, or ice, so you should slow down before reaching the marked stretch rather than after you feel the tires break loose.

Question 42Warning Signs and Roadway Alignment

You are driving at night on a rural Minnesota two-lane road and see a yellow diamond with a black arrow bending sharply to the left, plus a smaller yellow plaque below reading a speed such as 35 MPH. What does the plaque mean?

  1. The speed limit resumes after the curve
  2. The speed at which the curve becomes a passing zone
  3. The minimum legal speed through the curve
  4. The recommended maximum speed for the curve Correct answer.

Explanation

An advisory speed plaque under a curve warning sign gives the recommended maximum safe speed for that curve under good conditions. It is not the posted regulatory limit, but exceeding it in rain, snow, or darkness raises rollover and lane-departure risk significantly.

Question 43Warning Signs and Roadway Alignment

A yellow diamond sign displays a black symbol of a tractor. On a Minnesota county road, this sign primarily alerts you that:

  1. Slow-moving farm vehicles may be on or crossing the road Correct answer.
  2. The road surface becomes unpaved
  3. Livestock may be driven along the shoulder
  4. A farm equipment dealership is ahead

Explanation

The tractor warning sign alerts drivers that slow-moving farm implements operate on or cross the roadway, common on Minnesota rural routes. Because tractors travel well below highway speeds and may turn into fields without signaling early, reduce speed and prepare to stop.

Question 44Warning Signs and Roadway Alignment

While driving on a Minnesota highway you pass a yellow diamond showing a black cross symbol (a plus sign). What hazard does this sign identify?

  1. A railroad crossing ahead
  2. A church or cemetery entrance
  3. A four-way intersection ahead Correct answer.
  4. A hospital entrance ahead

Explanation

The plain cross symbol on a warning diamond marks a crossroad intersection where traffic may enter from either side. Scan for vehicles approaching from the left and right and be ready to adjust speed, since cross traffic may not stop.

Question 45Warning Signs and Roadway Alignment

A yellow diamond sign shows a black symbol of a pedestrian within a diagonal band or with a walking figure, placed near a school zone in Minnesota. What is the appropriate driver response?

  1. Reduce speed and watch for children crossing, especially during school hours Correct answer.
  2. Sound the horn continuously while passing the school
  3. Stop completely until a crossing guard appears
  4. Maintain speed because the sign is only advisory for children

Explanation

Pedestrian and school warning signs tell you to slow down and scan for people entering the roadway, particularly around arrival and dismissal times. Children may step out unpredictably, so lowering speed buys reaction time even when no crossing guard is present.

Question 46Warning Signs and Roadway Alignment

A yellow diamond sign on a Minnesota road shows a black symbol of a deer. What does this sign indicate?

  1. Deer may cross the road in this area Correct answer.
  2. A wildlife refuge boundary begins here
  3. Hunting is permitted along the shoulder
  4. A veterinary clinic is located ahead

Explanation

The deer warning sign marks an area where deer frequently cross, common along Minnesota's wooded and suburban fringe roads. Deer are most active near dawn and dusk, so reduce speed and scan the shoulders for movement and for animals following the first one.

Question 47Warning Signs and Roadway Alignment

You see a yellow diamond warning sign with a black symbol of a traffic signal. What does this sign tell you as you approach?

  1. The signal ahead is malfunctioning
  2. A signalized intersection is ahead, so prepare to stop Correct answer.
  3. The signal ahead is currently red for your direction
  4. The intersection has no signal and relies on stop signs

Explanation

The signal-ahead warning sign alerts drivers that a traffic light controls the upcoming intersection, which matters most where sight distance is limited by a hill or curve. It does not tell you the current color; you must still observe the actual signal and be ready to stop.

Question 48Warning Signs and Roadway Alignment

A yellow diamond sign shows a black symbol of a road narrowing on both sides. What should a Minnesota driver expect?

  1. The road ends and becomes a dead end
  2. The roadway ahead becomes narrower than the current section Correct answer.
  3. The lane count increases ahead
  4. The shoulder becomes a full-width driving lane

Explanation

The road-narrows warning sign tells you the pavement width ahead is reduced, whether on one side or both. Adjust position and speed early so you are not squeezed against oncoming traffic or the shoulder when the narrowing begins.

Question 49Warning Signs and Roadway Alignment

Approaching a Minnesota intersection, you see a yellow diamond with a black symbol of a side road entering from the right at an angle. What is the sign warning you about?

  1. The right lane ends ahead
  2. A one-way street begins ahead
  3. A side road enters or joins from the right ahead Correct answer.
  4. A right turn is prohibited ahead

Explanation

Side-road warning signs show the geometry of an intersecting road, in this case one joining from the right. Vehicles entering from that road may not stop or may enter slowly, so cover the brake and check for traffic before passing the junction.

Question 50Warning Signs and Roadway Alignment

A yellow diamond sign in Minnesota displays a black symbol of a truck on a downhill slope with a percentage figure such as 6%. What is this sign telling you?

  1. The road climbs at that grade for trucks only
  2. Trucks are prohibited from this route
  3. A steep downgrade of that percentage lies ahead Correct answer.
  4. Truck traffic must use a lower gear for the next mile

Explanation

The hill sign shows the direction and steepness of a grade, here a downgrade of the stated percentage. On a long descent, control speed by downshifting and braking gently rather than riding the brakes, which can overheat and fade.
