Question 1Regulatory Signs

Under Montana law, a driver who approaches a STOP sign at an intersection must come to a complete stop at which point?

  1. Only after yielding to traffic already in the intersection
  2. Anywhere within 50 feet before the intersection
  3. At the stop line, or at the nearest crosswalk or intersection edge if no line is marked Correct answer.
  4. At the center of the intersection before proceeding

Explanation

A stop sign requires a full halt at the marked stop line. When no line is painted, the stop is made at the nearest crosswalk or at the edge of the intersecting roadway before entering it. Rolling stops do not satisfy the requirement.

Question 2Regulatory Signs

A red octagonal sign at a rural Montana crossroads is approaching. What action does this shape and color combination require?

  1. Yield only to vehicles on your right
  2. Stop only if other traffic is present
  3. Slow down and proceed with caution
  4. Come to a complete stop before entering the intersection Correct answer.

Explanation

The octagon is used exclusively for STOP signs nationwide, and red reinforces the regulatory message. It always requires a complete stop regardless of whether other traffic is visible. The shape is recognizable from the back and in poor visibility.

Question 3Regulatory Signs

You are driving in Montana and see a red-and-white triangular sign with the point aimed downward. What does it mean?

  1. You must stop completely before proceeding
  2. You must yield and give way to traffic on the intersecting road Correct answer.
  3. You have the right-of-way over cross traffic
  4. The road ahead narrows to one lane

Explanation

The downward-pointing triangle is the YIELD sign, and its red-and-white coloring makes it conspicuous. It requires you to slow and let crossing or merging traffic go first, stopping only if necessary. It does not grant right-of-way.

Question 4Regulatory Signs

In Montana, a white rectangular sign reading SPEED LIMIT 65 is best described as which type of sign?

  1. An advisory sign for trucks only
  2. A warning sign advising a safe speed
  3. A guide sign showing a recommended speed
  4. A regulatory sign setting the legal maximum speed Correct answer.

Explanation

White rectangular signs with black legends are regulatory, and a posted speed limit establishes the legal maximum under normal conditions. Exceeding it is a violation. Warning signs, by contrast, are yellow diamonds.

Question 5Regulatory Signs

A white sign with a black arrow curving to the left and the word ONE WAY beneath it indicates what?

  1. The left lane ends ahead
  2. Traffic on that roadway moves only in the direction of the arrow Correct answer.
  3. The road curves left and then becomes two-way
  4. Drivers must turn left at the next intersection

Explanation

The ONE WAY sign is regulatory and marks a roadway where all traffic flows in a single direction. The arrow shows that direction, and entering against it is illegal and dangerous. It does not order a turn.

Question 6Regulatory Signs

A red circle with a diagonal slash over a black left-turn arrow means which of the following?

  1. Left turns are prohibited at this location Correct answer.
  2. Left turns are allowed after a complete stop
  3. Left turns must be made from the center lane
  4. Left turns are permitted only during green arrows

Explanation

A red circle with a slash is the universal prohibition symbol, and combined with a turn arrow it forbids that maneuver. The restriction applies at that location regardless of signal color. Drivers must choose another route or turn.

Question 7Regulatory Signs

On a Montana highway you see a white rectangular sign with the word WRONG WAY in red. What should you do immediately?

  1. Continue slowly until you reach an exit
  2. Stop, check for traffic, and back out or turn around to correct your direction Correct answer.
  3. Assume the sign is for opposing traffic and ignore it
  4. Sound your horn and proceed to the next lane

Explanation

WRONG WAY signs face drivers who have entered a one-way road or ramp against the flow of traffic. The only safe response is to stop as soon as it is safe and reverse or turn to exit the wrong-direction path. Continuing forward risks a head-on crash.

Question 8Regulatory Signs

A white sign showing a black symbol of a bicycle inside a red circle with a slash indicates what?

  1. A bicycle lane begins ahead
  2. Bicycles have the right-of-way
  3. Bicycles must use the shoulder
  4. Bicycles are prohibited from this facility Correct answer.

Explanation

The red circle and slash mark a prohibition, so a bicycle inside it means cyclists may not use that road, path, or lane. Regulatory prohibitions apply to the class of user shown. Other signs, such as green bike-lane markings, indicate where bicycles are allowed.

Question 9Regulatory Signs

A white rectangular sign reads NO PARKING ANY TIME. In Montana, what does this prohibit?

  1. Stopping briefly to load passengers
  2. Parking unless a permit is displayed
  3. Parking only during posted business hours
  4. Standing or leaving a vehicle at the curb at any hour Correct answer.

Explanation

NO PARKING ANY TIME is a regulatory sign that forbids leaving a vehicle along that curb or area around the clock. Brief stops to actively load or unload passengers may still be governed by separate stopping rules. The restriction is not time-limited or permit-based.

Question 10Regulatory Signs

A white sign with a black left-turn arrow and the words NO TURN ON RED is posted at an intersection. What does it require?

  1. A left turn on a red light is prohibited even after stopping Correct answer.
  2. Left turns are allowed only from the right lane
  3. No left turn may be made at any time
  4. The left-turn lane is closed ahead

Explanation

This sign modifies the general permission to turn left on red from a one-way street onto another one-way street. It forbids that turn during the red phase even after a complete stop. A green arrow or green light still permits the turn.

Question 11Regulatory Signs

A white sign reading KEEP RIGHT with a black arrow pointing diagonally right is placed at a traffic island. What is the required action?

  1. Turn right at the next intersection
  2. Merge left around the island
  3. Pass to the right side of the island or obstruction Correct answer.
  4. Stop before the island and wait for a gap

Explanation

KEEP RIGHT is a regulatory sign directing traffic to pass on the right side of a median, island, or obstruction. It controls the path of travel rather than ordering a turn. Passing on the wrong side could put you in opposing traffic.

Question 12Regulatory Signs

A white sign with the word STOP and a small arrow pointing to the left beneath it is mounted at an intersection. How should you interpret it?

  1. Stop is required only for traffic in the left lane
  2. The stop line for your approach is to the left of the sign Correct answer.
  3. The sign applies to cross traffic, not your lane
  4. Left-turning traffic must stop but through traffic may continue

Explanation

An arrow on a STOP sign indicates the location of the stop line relative to the sign, which helps drivers in wide approaches find the correct stopping point. It does not exempt any lane from stopping. All traffic on that approach must halt at the line.

Question 13Regulatory Signs

A white rectangular sign displays a black arrow pointing straight ahead with the word ONLY beneath it in a lane. What does this mean?

  1. The lane is reserved for through traffic and you must go straight from it Correct answer.
  2. The lane ends ahead and merges
  3. You may turn if no traffic is present
  4. Through traffic must yield to turning traffic

Explanation

A lane-use sign with an arrow and ONLY designates the movements permitted from that lane. Drivers in the lane must proceed straight and may not turn from it. Other movements require being in the properly marked lane.

Question 14Regulatory Signs

In Montana, a white sign marked with a red circle and slash over a symbol of a truck is posted on a mountain pass. What does it regulate?

  1. Trucks may proceed only in the right lane
  2. Trucks are prohibited from the route Correct answer.
  3. Trucks must stop for inspection
  4. Trucks must use low gear on the descent

Explanation

The red circle with a slash is a prohibition, so a truck symbol inside it bans trucks from that road. The restriction is categorical for the class shown. Gear, inspection, and lane rules would be conveyed by different regulatory or warning signs.

Question 15Regulatory Signs

A white sign reading DO NOT PASS is placed beside a two-lane Montana highway. What does it prohibit?

  1. Driving in the left lane at any time
  2. Exceeding the posted speed limit
  3. Passing slower vehicles using the opposing lane Correct answer.
  4. Passing on the right shoulder

Explanation

DO NOT PASS is a regulatory sign forbidding overtaking that requires entering the opposing lane. It is often paired with pavement markings and removed once sight distance improves. Passing on the right where a lane exists may still be legal under other rules.

Question 16Regulatory Signs

A white sign reading NO U-TURN appears at a divided highway median opening. What does it forbid?

  1. Entering the median to merge
  2. Reversing direction within the opening using a U-turn Correct answer.
  3. Crossing the median on foot
  4. Turning left into a side street

Explanation

NO U-TURN is a regulatory sign prohibiting a reversal of direction at that location. Drivers who miss a turn must continue to the next legal opportunity. Left turns into cross streets are controlled separately.

Question 17Regulatory Signs

A white sign with a black pedestrian symbol inside a red circle with a slash is posted along a highway. What is the effect?

  1. A crosswalk is located ahead
  2. Pedestrians have the right-of-way at all times
  3. Pedestrians are prohibited from crossing or walking along this roadway Correct answer.
  4. Pedestrians must walk facing traffic

Explanation

The slash converts the pedestrian symbol into a prohibition, barring pedestrians from that facility, which is common on controlled-access highways. It does not create a crosswalk or change right-of-way rules. Drivers should still watch for violators.

Question 18Regulatory Signs

A white sign reading RIGHT TURN ON RED PERMITTED AFTER STOP is posted at a Montana intersection. What does it authorize?

  1. A right turn from any lane on the approach
  2. A right turn only when a green arrow appears
  3. A right turn after a complete stop and yielding to traffic and pedestrians Correct answer.
  4. A right turn without stopping if the way is clear

Explanation

The sign confirms the general rule that a right turn on red is allowed after a full stop and after yielding to cross traffic and pedestrians. The stop is mandatory before the turn. A green arrow is not required.

Question 19Regulatory Signs

A white rectangular sign shows a black arrow pointing left and the legend ONE WAY. A driver facing it is on a road that intersects the one-way street. What does the sign tell the driver about the intersecting street?

  1. Traffic there is two-way but narrow
  2. Left turns onto it are prohibited
  3. Traffic there flows to the left only Correct answer.
  4. Traffic there flows to the right only

Explanation

The arrow on a ONE WAY sign shows the direction of travel on the roadway it identifies, so an arrow pointing left means that street carries traffic leftward. The sign informs drivers before they turn onto it. It does not prohibit the turn.

Question 20Regulatory Signs

A white sign reading SPEED LIMIT 55 with a smaller black-and-white plaque beneath reading TRUCKS 45 is posted on a Montana grade. How should a truck driver interpret it?

  1. Trucks must exit the highway
  2. The maximum lawful speed for trucks is 45 mph at this location Correct answer.
  3. The truck limit applies only when loaded
  4. Trucks may travel 55 if they maintain the lane

Explanation

A supplemental plaque posting a lower limit for trucks creates a separate, enforceable maximum for that vehicle class. The lower number controls for trucks regardless of load. Passenger vehicles remain bound by the main posted limit.

Question 21Regulatory Signs

At a Montana intersection, a STOP sign faces your approach while a YIELD sign faces the cross street. Who has priority, and why?

  1. Whoever arrives first, because both signs impose equal duties
  2. Cross-street traffic, because a yield sign always outranks a stop sign
  3. Neither; both must stop before proceeding
  4. Your approach, because traffic facing a stop sign must wait for cross traffic that is not required to stop Correct answer.

Explanation

Traffic facing a STOP sign must stop and yield to vehicles on the intersecting road. Because the cross street is controlled only by YIELD, those drivers need not stop unless traffic requires it, so they hold priority over your stopped approach. Right-of-way is assigned by the controls in place, not by arrival order.

Question 22Regulatory Signs

A white sign reading NO LEFT TURN is posted at an intersection, but a green left-turn arrow later illuminates for a dedicated lane. What is the correct interpretation?

  1. The sign applies only during rush hours, so the arrow is irrelevant
  2. The arrow cancels the sign only for vehicles turning from the through lane
  3. The sign bars left turns on the general signal, while the protected arrow authorizes the movement Correct answer.
  4. The sign permanently forbids all left turns, so the arrow must be for other traffic

Explanation

A NO LEFT TURN sign prohibits turns during the general or permissive phases. A protected green arrow in a dedicated turn lane authorizes the movement during that phase. Drivers must turn only when the arrow is displayed and from the proper lane.

Question 23Regulatory Signs

A white sign reading KEEP RIGHT is posted at a fork where the left branch leads to a one-way ramp marked with a red-circle-slash symbol over an arrow. What path is legal?

  1. Take either branch because KEEP RIGHT is advisory
  2. Stop at the fork and wait for directions
  3. Take the right branch, since the left ramp is prohibited Correct answer.
  4. Take the left ramp because KEEP RIGHT applies only to trucks

Explanation

KEEP RIGHT directs traffic to the right side of the obstruction, and the prohibition symbol on the left ramp independently bars entry there. Together they leave only the right branch as a lawful path. Advisory guidance would be posted in yellow, not white.

Question 24Regulatory Signs

A Montana driver parked at a curb sees a white sign reading NO PARKING 7 AM TO 9 AM MONDAY FOR STREET CLEANING. It is 8:30 AM on Monday. What is the status of the parking?

  1. Illegal only if a sweeper is actually present
  2. Illegal, because the vehicle is parked during the posted restricted window Correct answer.
  3. Legal, because street cleaning signs are advisory
  4. Legal, provided the driver remains within sight of the vehicle

Explanation

Regulatory parking signs create enforceable restrictions during the times and days shown. Parking inside that window is a violation regardless of whether the work is occurring. The driver must move the vehicle before the restriction begins.

Question 25Regulatory Signs

A white sign reading ONE WAY with an arrow pointing right is mounted facing you, but your lane's pavement arrows point left toward the same street. Which control governs your movement onto that street?

  1. The ONE WAY sign, because it states the legal direction of travel on that street Correct answer.
  2. Neither; the conflict makes the street two-way
  3. The pavement arrow, because pavement markings always override signs
  4. Whichever direction other drivers are using at the moment

Explanation

The ONE WAY sign establishes the lawful direction of travel on the street, and pavement markings that conflict with it are either worn, misplaced, or meant for another lane. Drivers must follow the signed direction and should not enter against it. Following other vehicles does not legalize a wrong-direction entry.

Question 26Regulatory Signs

In Montana, a white rectangular sign with black lettering reading SPEED LIMIT 70 establishes what for the roadway it faces?

  1. A suggested speed for unfamiliar drivers
  2. The maximum lawful speed under normal conditions Correct answer.
  3. The minimum speed permitted in the left lane
  4. The speed required during winter weather

Explanation

A white regulatory speed limit sign states the maximum lawful speed for that stretch of road in good conditions. Driving faster than the posted number is a violation unless a lower temporary limit is posted. The number is a legal ceiling, not a recommendation.

Question 27Regulatory Signs

A white sign reading DO NOT ENTER is posted facing you at a driveway. What does it mean for your movement?

  1. You must stop and then proceed
  2. You may enter if no traffic is visible
  3. You must not drive past the sign into that roadway Correct answer.
  4. You may enter only to turn around

Explanation

DO NOT ENTER marks a roadway, ramp, or driveway where traffic flows toward you, so you may not drive past it. It is commonly paired with a red circle and slash or with ONE WAY signs. Entering anyway puts you head-on against oncoming traffic.

Question 28Regulatory Signs

A white sign with black legend reading YIELD is posted at the end of an on-ramp. What action does it require of you?

  1. Sound your horn before entering the lane
  2. Maintain speed because merging traffic has priority
  3. Slow or stop as needed and let conflicting traffic go first Correct answer.
  4. Come to a complete stop before merging

Explanation

A YIELD sign requires you to slow or stop if necessary and give the right-of-way to traffic on the road you are entering. A full stop is required only when traffic conditions demand it. Merging vehicles must fit into a gap rather than claim priority.

Question 29Regulatory Signs

A white rectangular sign shows a black symbol of a person walking with a diagonal slash through it. What does this regulatory sign mean?

  1. Pedestrians are prohibited from that area Correct answer.
  2. A pedestrian crossing is ahead
  3. Pedestrians have the right-of-way
  4. Pedestrians must walk facing traffic

Explanation

A slash through a symbol on a white regulatory sign marks a prohibition, so this sign bars pedestrians from the roadway or area it faces. Prohibition signs use the slash consistently, as with no-turn or no-bicycle signs. It does not announce a crosswalk or grant priority.

Question 30Regulatory Signs

A white sign reading NO PARKING ANY TIME is posted along a Montana street. What does it prohibit?

  1. Backing into the space to unload cargo
  2. Stopping briefly to load passengers
  3. Standing in the lane while the engine runs
  4. Leaving a vehicle unattended at the curb Correct answer.

Explanation

NO PARKING ANY TIME forbids leaving a vehicle parked at the curb at all hours. Many such restrictions still allow a brief stop to pick up or drop off passengers, so parking means leaving the vehicle. Loading or waiting that exceeds a stop can be cited as parking.

Question 31Regulatory Signs

A white sign reading ONE WAY with a black arrow pointing left is mounted facing your approach. What does it tell you about that street?

  1. Traffic on it moves only to your left Correct answer.
  2. Left turns onto it are prohibited
  3. It is closed to through traffic
  4. It carries two-way traffic with a left lane

Explanation

A ONE WAY sign with a left-pointing arrow indicates that all traffic on that street flows in the direction the arrow points. You may travel on it only in that direction. Turning against the arrow would put you in the wrong direction.

Question 32Regulatory Signs

A white sign reading KEEP RIGHT with a black arrow angled to the right is placed at a median. What does it require?

  1. Pass to the right side of the median Correct answer.
  2. Turn right at the next intersection
  3. Merge right after signaling
  4. Yield to traffic entering from the right

Explanation

KEEP RIGHT directs drivers to pass on the right side of the median, island, or obstruction the sign marks. It is a channeling instruction, not a turn command. Passing on the wrong side would send you into opposing or restricted space.

Question 33Regulatory Signs

A white sign reading STOP with a smaller plaque beneath it reading ALL WAY is posted at a Montana intersection. What does the plaque change?

  1. Stopping is required only during busy hours
  2. Only the heaviest traffic must stop
  3. The cross street traffic must yield to you
  4. Every approach at the intersection has a stop sign Correct answer.

Explanation

An ALL WAY plaque under a STOP sign means stop signs control every approach, so all drivers must stop. At such intersections the first vehicle to stop and proceed generally has the right-of-way. It does not give your approach priority over the cross street.

Question 34Regulatory Signs

A white sign reading SPEED LIMIT 45 with a plaque below reading WHEN FLASHING is posted near a Montana school. What does the limit mean?

  1. The 45 mph limit applies only while the beacon is flashing Correct answer.
  2. The plaque cancels the speed limit during school hours
  3. The 45 mph limit applies at all times
  4. The plaque sets a minimum speed during school hours

Explanation

A WHEN FLASHING plaque ties the posted limit to the period when the warning beacon is operating, typically school arrival and dismissal. Outside those times the normal speed limit for the road applies. Drivers should watch for the beacon rather than assume the reduced limit always governs.

Question 35Regulatory Signs

A white sign reading NO TURN ON RED is posted beside a steady red signal at a Montana intersection. What does it require of a driver who wants to turn right?

  1. Turn right after the cross traffic clears without stopping
  2. Wait for a green light before turning right Correct answer.
  3. Stop, then turn right after yielding
  4. Turn right only if a police officer directs

Explanation

NO TURN ON RED removes the usual permission to turn right after stopping at a red light. The driver must remain stopped until the signal turns green, then turn when it is safe. Yielding alone does not satisfy the restriction.

Question 36Regulatory Signs

A white sign reading LEFT LANE MUST TURN LEFT is posted over the leftmost lane of a Montana arterial. A driver in that lane intends to go straight. What should the driver do?

  1. Stop in the lane and wait for a gap
  2. Continue straight because the sign is advisory
  3. Turn left and then make a U-turn
  4. Change to a lane that permits through travel Correct answer.

Explanation

LEFT LANE MUST TURN LEFT makes the left turn mandatory for vehicles in that lane, so a driver wanting to continue straight must move to another lane. The instruction is regulatory and enforceable. Ignoring it and proceeding straight conflicts with the designated turn movement.

Question 37Regulatory Signs

A white sign reading TRUCKS USE LOW GEAR is posted on a long downhill grade in Montana. What is the purpose of this regulatory instruction for truck drivers?

  1. To meet a posted minimum speed
  2. To keep the engine warm on the descent
  3. To reduce brake fade by using engine braking Correct answer.
  4. To shorten the distance to the next town

Explanation

On steep descents, relying on service brakes alone can overheat them and cause fade, so trucks are directed to use a low gear for engine braking. The sign is regulatory for the vehicles it names. It helps maintain control rather than serving engine temperature or speed minimums.

Question 38Regulatory Signs

A white sign reading NO RIGHT TURN ON RED is posted at an intersection where a driver faces a red arrow for right turns. What governs the turn?

  1. The driver may turn right if no pedestrians are present
  2. The driver may turn right after yielding to cross traffic
  3. The red arrow and the sign both bar the turn until a green arrow appears Correct answer.
  4. The driver may turn right after stopping because the sign is advisory

Explanation

A red arrow prohibits movement in the direction it controls, and the NO RIGHT TURN ON RED sign reinforces that no right turn may be made on red. The driver must wait for a green arrow or green light. Pedestrian presence or cross-traffic gaps do not override the restriction.

Question 39Regulatory Signs

A white sign reading NO PARKING 8 AM TO 10 AM TUESDAY FOR STREET SWEEPING is posted at a Montana curb. It is Tuesday at 9:15 AM. What does the sign mean?

  1. Parking is allowed for up to 30 minutes
  2. Parking is prohibited at that location at that time Correct answer.
  3. Parking is allowed if the sweeper has already passed
  4. Parking is prohibited only on the sweeper's side of the street

Explanation

The sign establishes a specific no-parking window tied to street sweeping, and during that window vehicles may not be left at the curb. The restriction applies whether or not the sweeper has been seen. Moving the vehicle before the window ends avoids a citation and allows the sweep.

Question 40Regulatory Signs

A white sign reading RIGHT LANE MUST TURN RIGHT is posted over the right lane approaching an intersection. A driver in that lane wants to continue straight through. What is the correct action?

  1. Move to a lane that allows through travel Correct answer.
  2. Turn right and then re-enter the road
  3. Stop and wait for the light to change
  4. Proceed straight and ignore the sign

Explanation

A mandatory turn sign makes the right turn compulsory for the designated lane, so a driver intending to go straight must change lanes beforehand. The instruction is enforceable and keeps turn and through movements separated. Continuing straight from a right-turn-only lane creates conflicts.

Question 41Regulatory Signs

A white sign reading TWO-WAY TRAFFIC AHEAD is posted after you exit a freeway onto a Montana frontage road. What should you expect?

  1. The road becomes one-way in your direction
  2. A divided highway begins ahead
  3. Oncoming vehicles may share the roadway ahead Correct answer.
  4. A passing lane opens ahead

Explanation

This regulatory sign warns that the road you are entering carries traffic in both directions, so oncoming vehicles may be present. Drivers must keep to the right and pass only where permitted. It is especially important after leaving a divided or one-way facility.

Question 42Regulatory Signs

A white sign reading NO BICYCLES is posted at the entrance to a limited-access Montana highway ramp. What does it mean for a cyclist?

  1. The cyclist must use an alternate route Correct answer.
  2. The cyclist may proceed if wearing a helmet
  3. The cyclist may ride on the shoulder
  4. The cyclist must walk the bicycle on the shoulder

Explanation

A NO BICYCLES sign bars cyclists from the roadway or facility it faces, so the cyclist must choose another route. The restriction applies regardless of shoulder space or safety gear. Riding or walking past the sign would violate it.

Question 43Regulatory Signs

A white sign reading NO U-TURN is posted at a median opening on a divided Montana highway. A driver misses a turn and wants to reverse direction. What is permitted?

  1. Continuing to an interchange or intersection where a legal turnaround exists Correct answer.
  2. A U-turn after coming to a full stop
  3. A three-point turn across the median
  4. A U-turn if traffic is light

Explanation

NO U-TURN forbids reversing direction at that median opening, so the driver must continue to a place where a turnaround is legal, such as an interchange or a permitted intersection. Light traffic or a full stop does not override the sign. Crossing the median is likewise prohibited.

Question 44Regulatory Signs

A white sign reading LEFT TURN YIELD ON GREEN is posted at a Montana intersection with a protected-permissive left turn. What does it require of a driver turning left on a green circle?

  1. Yield to oncoming traffic before completing the left turn Correct answer.
  2. Wait for a green arrow before entering the intersection
  3. Turn immediately because the green gives full priority
  4. Stop and wait for the light to turn red

Explanation

A permissive left turn on a green circle requires the driver to yield to oncoming traffic before completing the turn. The sign clarifies that the green light does not create a protected movement. A green arrow later in the cycle provides the protected turn.

Question 45Regulatory Signs

A white sign reading NO LEFT TURN is posted at an intersection, but a dedicated left-turn lane with its own signal serves a different approach. How should a driver on the signed approach interpret the restriction?

  1. The driver may turn left if no sign forbids it later
  2. The driver may turn left during off-peak hours
  3. The driver may never turn left from that approach Correct answer.
  4. The driver may turn left if a green arrow appears for the cross street

Explanation

The NO LEFT TURN sign applies to the approach it faces, so drivers on that approach may not turn left regardless of signals serving other approaches. A green arrow for another direction does not authorize this movement. The restriction remains in force at all hours.

Question 46Regulatory Signs

A white sign reading DO NOT PASS with a plaque reading TRUCKS OVER 10,000 LBS is posted on a two-lane Montana highway. Who is restricted?

  1. Only buses carrying passengers
  2. All vehicles regardless of size
  3. Only vehicles towing trailers
  4. Only trucks above the stated weight Correct answer.

Explanation

The plaque limits the no-passing restriction to trucks exceeding the stated weight, so lighter vehicles are not bound by it. Plaques modify the sign above them, and drivers must read both together. Other passing rules, such as pavement markings, may still apply.

Question 47Regulatory Signs

A white sign reading SPEED LIMIT 65 is posted, and a smaller plaque below reads MINIMUM 40. What do the two numbers establish for that roadway?

  1. A maximum of 65 and a minimum of 40 under normal conditions Correct answer.
  2. A maximum of 40 and a suggested speed of 65
  3. A maximum of 65 only during daylight
  4. A minimum of 65 and no maximum

Explanation

The main sign sets the maximum lawful speed at 65, while the MINIMUM plaque sets a floor of 40 for normal conditions. Driving far below the minimum can impede traffic and be cited. Neither number is limited to daylight hours unless a plaque says so.

Question 48Regulatory Signs

A white sign reading KEEP RIGHT is posted at a fork where the left branch is marked with a red circle and slash over an arrow. What does the combination require?

  1. Take the right branch and avoid the prohibited left branch Correct answer.
  2. Take the left branch slowly
  3. Stop before choosing a branch
  4. Take either branch because the slash sign is advisory

Explanation

KEEP RIGHT channels traffic to the right branch, and the slashed arrow on the left branch marks that movement as prohibited. Together they require the driver to use the right branch. Neither sign is merely advisory.

Question 49Regulatory Signs

A white sign reading NO PARKING 6 PM TO 6 AM is posted on one side of a Montana street, while the opposite curb has no sign. At 10 PM, what is the rule for the signed side?

  1. Parking is allowed on the signed side because it is dark
  2. Parking is prohibited on the signed side only on weekdays
  3. Parking is prohibited on both sides during those hours
  4. Parking is prohibited on the signed side during those hours Correct answer.

Explanation

A no-parking sign governs the curb or side of the street where it is posted, so the overnight restriction applies there. The unsigned opposite curb is not controlled by that sign. Unless another sign states weekday limits, the ban applies every night in the window.

Question 50Regulatory Signs

A white sign reading RIGHT TURN ONLY is posted at an intersection where the cross street is marked DO NOT ENTER from your direction. What must a driver do?

  1. Proceed straight through the intersection
  2. Turn right and then enter the do-not-enter roadway
  3. Turn right and proceed in the legal direction on the cross street Correct answer.
  4. Turn left to avoid the restriction

Explanation

RIGHT TURN ONLY makes the right turn mandatory, and the DO NOT ENTER sign on the cross street applies to traffic approaching from the direction it faces. Turning right and traveling in the lawful direction satisfies both. Entering against the DO NOT ENTER sign would be a wrong-way move.
