Question 1Regulatory signs (speed limits, stop/yield, lane and turn controls, parking restrictions)

In Massachusetts, what does a solid white rectangular sign reading SPEED LIMIT 30 mean for a driver on that road?

  1. The limit applies only to trucks and buses
  2. The minimum lawful speed is 30 mph at all times
  3. The maximum lawful speed is 30 mph in good conditions Correct answer.
  4. A speed of 30 mph is only a suggestion

Explanation

A white rectangular sign with black lettering reading SPEED LIMIT and a number sets the maximum lawful speed for that stretch of road. The number is a legal limit, not advice, so exceeding it is a speeding violation. Drivers must also slow below it when weather, traffic, or visibility make the posted speed unsafe.

Question 2Regulatory signs (speed limits, stop/yield, lane and turn controls, parking restrictions)

You approach a red octagonal sign at an intersection with no other traffic present. What is the required action in Massachusetts?

  1. Yield only to vehicles coming from the right
  2. Come to a complete stop before the stop line or crosswalk Correct answer.
  3. Slow to about 10 mph and continue if clear
  4. Stop only if a police officer is directing traffic

Explanation

The octagonal red sign means a full stop is required regardless of traffic conditions. You must stop at the marked stop line, at the crosswalk, or at the edge of the intersecting roadway if neither is present. Rolling stops are a common violation and are not permitted.

Question 3Regulatory signs (speed limits, stop/yield, lane and turn controls, parking restrictions)

A downward-pointing red and white triangular sign requires you to do which of the following?

  1. Merge without changing speed
  2. Stop completely before entering the intersection
  3. Slow down and give the right of way to cross traffic Correct answer.
  4. Sound your horn before proceeding

Explanation

The inverted triangle is the yield sign. It requires you to slow down and let traffic on the intersecting road pass before you enter or merge. A full stop is only required when necessary to avoid conflict with that traffic.

Question 4Regulatory signs (speed limits, stop/yield, lane and turn controls, parking restrictions)

A white rectangular sign shows a black arrow curving to the left with a red circle and slash over it. What does this sign tell you?

  1. Left turns are allowed only during daylight
  2. The left lane ends ahead
  3. Left turns are prohibited at this location Correct answer.
  4. A left turn is permitted after a full stop

Explanation

A red circle with a diagonal slash is the universal prohibition symbol. When it overlays a turn arrow, that maneuver is not allowed at that location. You must choose another route rather than making the turn.

Question 5Regulatory signs (speed limits, stop/yield, lane and turn controls, parking restrictions)

What does a white rectangular sign reading ONE WAY with a black arrow indicate?

  1. The road has one lane open to two-way traffic
  2. Traffic on that road moves only in the direction of the arrow Correct answer.
  3. The arrow points to the nearest one-way street entrance
  4. Only one vehicle may enter the road at a time

Explanation

The ONE WAY sign marks a road or lane where all traffic flows in the arrow's direction. Driving against that direction is illegal and dangerous because oncoming drivers will not expect you. You must enter and travel only in the indicated direction.

Question 6Regulatory signs (speed limits, stop/yield, lane and turn controls, parking restrictions)

A white sign shows a red circle with a slash over a black letter P. What does this sign mean?

  1. Parking is prohibited at this location Correct answer.
  2. Parking is reserved for permit holders
  3. Parking is allowed for a limited time
  4. You may stop briefly to load passengers

Explanation

The letter P inside a red circle with a diagonal slash is the no parking symbol. Parking, and in many placements standing, is not allowed there. The restriction is regulatory and enforceable, not a suggestion.

Question 7Regulatory signs (speed limits, stop/yield, lane and turn controls, parking restrictions)

A white rectangular sign reading DO NOT PASS with a red slash over a black arrow means which of the following?

  1. You may pass only vehicles traveling below the speed limit
  2. You may not overtake other vehicles in this zone Correct answer.
  3. You must move to the left lane to pass
  4. Passing is allowed if the road ahead is clear

Explanation

A DO NOT PASS sign with the prohibition symbol marks a zone where overtaking is not permitted. The restriction usually reflects limited sight distance or a hazard ahead. You must stay behind slower vehicles until the restriction ends.

Question 8Regulatory signs (speed limits, stop/yield, lane and turn controls, parking restrictions)

A white rectangular sign reading KEEP RIGHT with an arrow pointing right tells a driver to do what?

  1. Stay to the right of the median or divider Correct answer.
  2. Move into the right lane only to pass
  3. Yield to traffic entering from the right
  4. Turn right at the next intersection

Explanation

KEEP RIGHT directs traffic to pass to the right side of a median, island, or obstruction. It is often placed at divided highways and channelized intersections. Following it keeps you on the correct side and out of opposing traffic.

Question 9Regulatory signs (speed limits, stop/yield, lane and turn controls, parking restrictions)

You are driving in the left lane of a multi-lane road and see a white sign with a red X over your lane. What should you do?

  1. Speed up to clear the lane before it closes
  2. Stop immediately in your lane
  3. Continue in the lane because the X applies only to trucks
  4. Move to a lane marked with a green arrow Correct answer.

Explanation

In lane-use control signals, a red X marks a lane that is closed to your direction of travel. A green arrow marks a lane that is open. You should change into an open lane when it is safe to do so.

Question 10Regulatory signs (speed limits, stop/yield, lane and turn controls, parking restrictions)

A white sign shows a black arrow pointing straight ahead with the word ONLY beneath it. What does this sign require at the intersection?

  1. The lane is reserved for through trucks
  2. You must proceed straight from this lane Correct answer.
  3. You may turn after signaling
  4. You must stop before proceeding straight

Explanation

An arrow with ONLY beneath it designates a lane for that single movement. Drivers in that lane must make the indicated movement and cannot turn from it. If you intend to turn, you must be in the correctly marked lane.

Question 11Regulatory signs (speed limits, stop/yield, lane and turn controls, parking restrictions)

A white sign shows a red circle with a slash over a black U-shaped arrow. What maneuver is prohibited?

  1. Backing into a driveway
  2. Changing lanes within the intersection
  3. Making a U-turn at this location Correct answer.
  4. Turning left at the intersection

Explanation

The U-shaped arrow with a prohibition symbol bans U-turns at that location. U-turns are often restricted where sight distance is short or traffic is heavy. You must continue to a place where a U-turn is legal.

Question 12Regulatory signs (speed limits, stop/yield, lane and turn controls, parking restrictions)

A white sign at a parking space reads PARKING 8 AM TO 6 PM. How should a driver interpret this?

  1. Parking is permitted during those hours subject to any other posted limits Correct answer.
  2. Parking is allowed only outside those hours
  3. Parking is free of charge for exactly ten hours
  4. The space is reserved for deliveries during those hours

Explanation

A sign giving a time range for PARKING indicates when parking is allowed at that space. Outside the stated hours, other rules or restrictions may apply. Drivers should also check for meter, permit, or duration limits posted nearby.

Question 13Regulatory signs (speed limits, stop/yield, lane and turn controls, parking restrictions)

A white sign reads NO PARKING ANY TIME with an arrow pointing right. Where does the restriction apply?

  1. To both sides of the sign equally
  2. Directly in front of the sign only
  3. To the right of the sign in the direction the arrow points Correct answer.
  4. To the left of the sign only

Explanation

Arrows on parking signs indicate the stretch of curb the restriction covers. An arrow pointing right means the rule applies from the sign in that direction. Without arrows, the restriction typically applies where the sign is placed.

Question 14Regulatory signs (speed limits, stop/yield, lane and turn controls, parking restrictions)

A white sign shows a black arrow curving right above a smaller arrow pointing straight. What does this combination indicate?

  1. Right turns are prohibited from the through lane
  2. The right lane must turn right and the left lane may go straight Correct answer.
  3. All traffic must turn right from every lane
  4. The road curves right ahead and then continues straight

Explanation

Combination lane-use signs show the permitted movement for each lane, read left to right. The right-curving arrow marks a mandatory right-turn lane, while the straight arrow marks a lane that continues through. Drivers should choose the lane matching their intended route.

Question 15Regulatory signs (speed limits, stop/yield, lane and turn controls, parking restrictions)

You see a white sign reading MINIMUM SPEED 40 on a limited-access highway. What does it require?

  1. You may not exceed 40 mph on the highway
  2. You must use the left lane when traveling 40 mph
  3. You must travel at least 40 mph unless conditions require slower Correct answer.
  4. Trucks must maintain exactly 40 mph

Explanation

A minimum speed sign sets a floor for normal travel so slow vehicles do not disrupt traffic flow. You must keep pace at or above that speed when conditions allow. In bad weather, congestion, or emergencies, driving slower for safety is still required and permitted.

Question 16Regulatory signs (speed limits, stop/yield, lane and turn controls, parking restrictions)

A white sign on a city street reads NO STANDING. What does this prohibit?

  1. Walking in the roadway at any point
  2. Stopping for a red light at the corner
  3. Waiting in the vehicle, including briefly to pick up a passenger Correct answer.
  4. Leaving the vehicle parked for more than one hour

Explanation

No standing prohibits waiting in a vehicle at the curb, even with a driver present and the engine running. It is stricter than a no parking sign, which allows brief stopping to load or unload. Obeying traffic signals is unrelated to the restriction.

Question 17Regulatory signs (speed limits, stop/yield, lane and turn controls, parking restrictions)

A white sign shows a black arrow bending left and the word ONLY. A driver who needs to go straight is in that lane. What is the correct action?

  1. Proceed straight because ONLY is advisory
  2. Turn left and then find a legal route to the destination Correct answer.
  3. Back up to the previous lane
  4. Stop in the lane and wait for a gap to change lanes

Explanation

A left-turn ONLY lane requires every vehicle in it to turn left. Continuing straight from that lane is both illegal and a collision risk with through traffic. The driver should complete the required turn and reroute afterward.

Question 18Regulatory signs (speed limits, stop/yield, lane and turn controls, parking restrictions)

A white rectangular sign reading YIELD HERE TO PEDESTRIANS is placed at a crosswalk. What does it require of drivers?

  1. Drivers must give way to pedestrians in the crosswalk Correct answer.
  2. Drivers must sound the horn before crossing the crosswalk
  3. Pedestrians must wait for a gap in traffic
  4. Drivers must stop only if a pedestrian raises a hand

Explanation

The sign reinforces the legal duty to yield to pedestrians using the crosswalk. Drivers should slow on approach and stop when a pedestrian is crossing or about to cross. Pedestrians in a marked crosswalk have the right of way.

Question 19Regulatory signs (speed limits, stop/yield, lane and turn controls, parking restrictions)

A white sign reads NO RIGHT TURN ON RED. A driver stopped at the red light wants to turn right onto a clear street. What must the driver do?

  1. Turn right after a complete stop and a signal
  2. Turn right if no pedestrians are present
  3. Wait for the light to turn green before turning Correct answer.
  4. Turn right after yielding to cross traffic only

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. Proceeding on red, even after a full stop, violates the posted restriction.

Question 20Regulatory signs (speed limits, stop/yield, lane and turn controls, parking restrictions)

A white sign on a highway ramp reads DO NOT ENTER with a red circle. A driver mistakenly heading toward it should do what?

  1. Stop and turn around before proceeding further Correct answer.
  2. Flash headlights and proceed with caution
  3. Drive to the side of the ramp to let oncoming traffic pass
  4. Continue slowly in case the ramp is one-way toward them

Explanation

DO NOT ENTER marks a roadway that traffic may not enter, often the exit ramp of a divided highway. Continuing would put the driver against the flow of traffic. The safe response is to stop and reverse course before entering the wrong-way roadway.

Question 21Regulatory signs (speed limits, stop/yield, lane and turn controls, parking restrictions)

A white sign reads NO PARKING 7 AM TO 9 AM ON MONDAY AND THURSDAY FOR STREET CLEANING. It is 8 AM on Wednesday. May the driver park there?

  1. No, because the sign bars parking during all morning hours
  2. Yes, because the restriction lists only Monday and Thursday Correct answer.
  3. Yes, but only for up to thirty minutes
  4. No, because street cleaning restrictions apply every weekday

Explanation

Parking restrictions apply only during the days and hours stated on the sign. Wednesday is not listed, so the cleaning restriction does not bar parking at that time. Drivers should still check for other signs covering the same space.

Question 22Regulatory signs (speed limits, stop/yield, lane and turn controls, parking restrictions)

A white sign shows a black arrow pointing straight with ONLY beneath it and a second sign beside it reading NO TRUCKS. How should a truck driver interpret the combination?

  1. The truck may not use this route at all Correct answer.
  2. The truck must use the through lane regardless of destination
  3. The truck must turn because trucks cannot travel straight
  4. The truck may turn from the through lane if traffic is light

Explanation

The NO TRUCKS sign bars trucks from the roadway or route where it is posted. The lane-use arrow applies to vehicles permitted on that road, so a truck driver cannot satisfy both signs by changing lanes. The driver must take an alternate route.

Question 23Regulatory signs (speed limits, stop/yield, lane and turn controls, parking restrictions)

A white sign reads NO LEFT TURN 4 PM TO 6 PM. It is 5:30 PM and the driver's destination requires a left turn at that intersection. What is the best legal action?

  1. Make a U-turn in the intersection instead
  2. Continue past the intersection and turn left at a later legal point Correct answer.
  3. Make the left turn after yielding to oncoming traffic
  4. Wait at the intersection until 6 PM and then turn

Explanation

Time-limited turn restrictions apply during the posted hours, so the left turn is illegal at 5:30 PM. The driver should proceed and find a legal place to turn, such as a later intersection. Waiting at the corner would obstruct traffic and is unsafe.

Question 24Regulatory signs (speed limits, stop/yield, lane and turn controls, parking restrictions)

A driver sees a white sign reading RIGHT LANE MUST TURN RIGHT and a second sign reading NO RIGHT TURN ON RED. The light is red. What must the driver in the right lane do?

  1. Turn right after stopping because the lane requires it
  2. Remain stopped until the signal turns green, then complete the right turn Correct answer.
  3. Proceed through the red light to clear the turn lane
  4. Change lanes to go straight through the intersection

Explanation

The lane assignment requires a right turn from that lane, but the red-light restriction bars turning on red. Both rules apply together, so the driver waits for green and then turns. Lane assignment never authorizes running a red signal.

Question 25Regulatory signs (speed limits, stop/yield, lane and turn controls, parking restrictions)

A sign reads SPEED LIMIT 45 and, directly below, a smaller white sign reads TRUCKS 35. A truck driver traveling at 40 mph on this road is doing what?

  1. Complying, because the general limit applies to all vehicles
  2. Exceeding the posted limit for trucks Correct answer.
  3. Exceeding the general limit for passenger cars
  4. Complying, because truck limits are advisory only

Explanation

A supplemental sign applying a lower limit to trucks sets the enforceable maximum for those vehicles. The truck driver at 40 mph is above the 35 mph truck limit even though below the general limit. Truck drivers must obey the lower posted number.

Question 26Regulatory signs (speed limits, stop/yield, lane and turn controls, parking restrictions)

A white rectangular sign shows the words SPEED LIMIT 30. In Massachusetts, what does this sign establish for the road ahead?

  1. The minimum speed for the fastest lane
  2. The maximum lawful speed under normal conditions Correct answer.
  3. A speed that is required at all times
  4. A suggested speed for curves only

Explanation

A SPEED LIMIT sign sets the maximum lawful speed for that stretch of road when conditions are normal. Driving faster than the posted number is a violation, but drivers must also slow below it when weather, traffic, or visibility require. The number is a ceiling, not a target or a minimum.

Question 27Regulatory signs (speed limits, stop/yield, lane and turn controls, parking restrictions)

A red and white sign with eight sides reads STOP. What is the required action at this sign?

  1. Come to a complete stop and yield the right of way Correct answer.
  2. Slow down and proceed if the way looks clear
  3. Stop only if a pedestrian is in the crosswalk
  4. Stop only when another vehicle is approaching

Explanation

The octagonal STOP sign requires a full stop at the stop line, crosswalk, or edge of the intersection. After stopping, the driver yields to pedestrians and to cross traffic before proceeding. A rolling or partial stop does not satisfy the requirement.

Question 28Regulatory signs (speed limits, stop/yield, lane and turn controls, parking restrictions)

A downward-pointing red and white triangle sign reads YIELD. What does this sign require of an approaching driver?

  1. Maintain speed and merge without checking
  2. Slow down and give the right of way to cross traffic Correct answer.
  3. Sound the horn before proceeding
  4. Stop fully before entering the intersection

Explanation

A YIELD sign means the driver must slow and be prepared to stop if necessary to let cross traffic and pedestrians go first. If the way is clear, the driver may proceed without a full stop. Failing to yield when others have the right of way is a violation.

Question 29Regulatory signs (speed limits, stop/yield, lane and turn controls, parking restrictions)

A white sign shows a black arrow pointing straight ahead with ONLY beneath it. What does this sign mean for the lane it marks?

  1. The lane is reserved for through traffic, and drivers must continue straight Correct answer.
  2. Drivers may turn or go straight from this lane
  3. The lane ends ahead and traffic must merge left
  4. The lane is for buses only

Explanation

A straight-ahead arrow with ONLY means the lane is a through lane and vehicles in it must continue straight through the intersection. Turning from that lane is not allowed. Drivers who need to turn should have chosen a lane marked for that movement.

Question 30Regulatory signs (speed limits, stop/yield, lane and turn controls, parking restrictions)

A white sign shows a red circle with a slash over a black letter P. What does this sign prohibit?

  1. Standing for less than five minutes
  2. Stopping to load passengers
  3. Parking at any time Correct answer.
  4. Waiting with the engine running

Explanation

A red circle and slash over a P is the regulatory symbol for no parking. Drivers may not leave a vehicle parked in the marked area. The restriction is separate from no standing and no stopping rules, which are posted with words.

Question 31Regulatory signs (speed limits, stop/yield, lane and turn controls, parking restrictions)

A white sign reads ONE WAY with an arrow pointing left. What does this sign tell a driver?

  1. The left lane is closed ahead
  2. Traffic on the road ahead moves only in the direction of the arrow Correct answer.
  3. The road ahead is a dead end
  4. Drivers must turn left at the next intersection

Explanation

A ONE WAY sign indicates that all traffic on that roadway travels in the direction shown by the arrow. Entering against the arrow is prohibited and dangerous. The sign describes the road, not a required turn for the driver.

Question 32Regulatory signs (speed limits, stop/yield, lane and turn controls, parking restrictions)

A white rectangular sign reads NO TURN ON RED. What does this sign change about a driver's ability to turn at the intersection?

  1. It prohibits left turns only
  2. It allows a right turn after a full stop
  3. It applies only during rush hours
  4. It prohibits turning right or left while the signal is red Correct answer.

Explanation

NO TURN ON RED means a driver may not turn right or left while the light is red, even after stopping. The driver must wait for a green signal or a green arrow. The restriction applies at all hours unless a supplementary sign states otherwise.

Question 33Regulatory signs (speed limits, stop/yield, lane and turn controls, parking restrictions)

A white sign with red lettering reads WRONG WAY. What should a driver do upon seeing it?

  1. Stop and back out of the roadway immediately
  2. Recognize that the vehicle is facing opposing traffic and stop safely Correct answer.
  3. Continue slowly to the next exit
  4. Treat it as a warning to reduce speed only

Explanation

A WRONG WAY sign faces drivers who are heading into opposing traffic, often at a ramp or one-way street. The driver should stop as soon as it is safe and turn around rather than continue. Continuing forward risks a head-on crash.

Question 34Regulatory signs (speed limits, stop/yield, lane and turn controls, parking restrictions)

A white sign reads NO PARKING 8 AM TO 6 PM with an arrow pointing left. It is 10 AM. How does the restriction apply?

  1. Parking is allowed for 30 minutes on the left side
  2. No parking between 8 AM and 6 PM on the right side of the sign
  3. No parking at any time on the left side
  4. No parking between 8 AM and 6 PM on the left side of the sign Correct answer.

Explanation

The arrow shows which side of the sign the restriction covers, and the times show when it is in force. Here parking is barred on the left side from 8 AM to 6 PM, so at 10 AM it applies. Outside those hours parking may be allowed unless another sign says otherwise.

Question 35Regulatory signs (speed limits, stop/yield, lane and turn controls, parking restrictions)

A white sign reads NO STANDING. What does this prohibit a driver from doing?

  1. Waiting in a moving traffic queue
  2. Parking for longer than one hour
  3. Halting temporarily to let a passenger out Correct answer.
  4. Stopping for a red light

Explanation

No standing bars a vehicle from waiting in place, including briefly to load or unload passengers, though a momentary stop to obey traffic controls is different. No parking is a lesser restriction because it still permits brief stops. Drivers should look for the specific wording posted.

Question 36Regulatory signs (speed limits, stop/yield, lane and turn controls, parking restrictions)

A white sign shows a black arrow curving right above a smaller straight arrow. In a lane-control context, what does this combination indicate?

  1. Drivers in the lane may either turn right or continue straight
  2. The lane must turn right and through movement is not permitted Correct answer.
  3. The right turn is optional and through traffic has priority
  4. The lane is closed to right turns

Explanation

When a turn arrow is shown with ONLY, or a turn arrow dominates a straight arrow, the lane is dedicated to the turn. Drivers in that lane must make the indicated turn and cannot continue straight. Choosing the wrong lane means following the arrow and rerouting later.

Question 37Regulatory signs (speed limits, stop/yield, lane and turn controls, parking restrictions)

A white sign reads NO LEFT TURN 4 PM TO 6 PM. A driver reaches the intersection at 5:30 PM and needs to turn left. What is the correct action?

  1. Turn left only if no other vehicle is waiting
  2. Turn left after yielding to oncoming traffic
  3. Continue straight or turn right, then find another route Correct answer.
  4. Wait at the light until 6 PM, then turn left

Explanation

During the posted hours the left turn is prohibited regardless of traffic conditions. The driver must use another permitted movement and reroute. Waiting at the intersection until the restriction ends would block traffic and is not a lawful solution.

Question 38Regulatory signs (speed limits, stop/yield, lane and turn controls, parking restrictions)

A white sign reads MINIMUM SPEED 45 on an interstate. Traffic is light and the weather is clear. What does the sign require?

  1. Drivers should aim for 45 mph as a target
  2. Drivers must travel at least 45 mph in that zone Correct answer.
  3. Drivers must use the left lane above 45 mph
  4. Drivers may not exceed 45 mph

Explanation

A minimum speed sign sets a floor for travel in the posted zone, intended to keep traffic moving safely on limited-access highways. A driver unable to maintain that speed, such as a slow-moving or disabled vehicle, should use hazard lights and leave the roadway safely. The minimum does not replace the posted maximum.

Question 39Regulatory signs (speed limits, stop/yield, lane and turn controls, parking restrictions)

A white sign on a divided highway reads KEEP RIGHT with an arrow. What does this sign direct a driver to do?

  1. Yield to traffic entering from the right
  2. Stay in or move to the right-hand lane or side of the median Correct answer.
  3. Turn right at the next intersection
  4. Exit the highway at the next ramp

Explanation

KEEP RIGHT directs traffic to stay to the right of a median, island, or obstruction so that opposing or passing traffic can flow on the left. It is about lane position, not about making a turn or exiting. Drivers should follow the arrow and keep the indicated side.

Question 40Regulatory signs (speed limits, stop/yield, lane and turn controls, parking restrictions)

A white sign shows a red X over the left lane of a multi-lane road, while a green arrow appears over the right lane. What do these signals mean?

  1. The left lane is open and the right lane is closed
  2. The left lane is closed to travel and the right lane is open Correct answer.
  3. Both lanes are closed ahead
  4. Both lanes are open but the left is for passing

Explanation

In lane-control signals, a red X means the lane is closed and must not be used, while a green arrow means the lane is open. Drivers in a closed lane should merge safely into an open one. The signals can change, so drivers should keep watching them.

Question 41Regulatory signs (speed limits, stop/yield, lane and turn controls, parking restrictions)

A white sign reads RIGHT LANE MUST TURN RIGHT, and a second sign reads NO RIGHT TURN ON RED. The light is red and the driver is in the right lane. What must the driver do?

  1. Wait for a green light before turning right Correct answer.
  2. Change lanes and proceed straight through the red
  3. Turn right after stopping because the lane requires it
  4. Turn right without stopping because the lane is a turn lane

Explanation

The mandatory turn sign requires a right turn from that lane, but the no-turn-on-red sign forbids turning while the signal is red. The driver must wait for a green light or green arrow, then complete the required turn. The lane requirement does not override the signal restriction.

Question 42Regulatory signs (speed limits, stop/yield, lane and turn controls, parking restrictions)

A sign reads SPEED LIMIT 45, and a smaller white sign below reads TRUCKS 35. A truck driver is traveling at 40 mph. What is the status of that speed?

  1. Lawful because truck limits are advisory only
  2. Unlawful because the truck limit of 35 mph applies Correct answer.
  3. Unlawful because trucks must travel at exactly 35 mph
  4. Lawful because it is below the general 45 mph limit

Explanation

The supplemental TRUCKS 35 sign sets a lower maximum for trucks in that zone, and the lower limit controls for those vehicles. A truck traveling 40 mph exceeds its applicable limit even though it is under the general limit. The general limit applies to other vehicles.

Question 43Regulatory signs (speed limits, stop/yield, lane and turn controls, parking restrictions)

A white sign reads DO NOT ENTER, and a driver realizes the vehicle is on a ramp heading toward it. What is the safest correct response?

  1. Back up along the ramp to the entrance
  2. Stop as soon as it is safe and turn the vehicle around Correct answer.
  3. Continue to the next exit and turn around there
  4. Proceed slowly and flash the headlights

Explanation

DO NOT ENTER marks a roadway or ramp where traffic flows toward the driver, so continuing risks a head-on collision. The driver should stop as soon as it is safe and reverse direction rather than proceed. Backing a long distance on a ramp is itself dangerous.

Question 44Regulatory signs (speed limits, stop/yield, lane and turn controls, parking restrictions)

A white sign shows a red circle with a slash over a black U-shaped arrow. What does this sign prohibit?

  1. Left turns onto a one-way street
  2. Entering a dead-end street
  3. Right turns at the intersection
  4. U-turns at that location Correct answer.

Explanation

A red circle and slash over a U-shaped arrow is the regulatory symbol for no U-turn. The maneuver is prohibited at that location, often because visibility or lane geometry makes it unsafe. Drivers needing to reverse direction should continue to a permitted location.

Question 45Regulatory signs (speed limits, stop/yield, lane and turn controls, parking restrictions)

A white sign reads NO PARKING 7 AM TO 9 AM ON MONDAY AND THURSDAY FOR STREET CLEANING. It is 8 AM on Wednesday. May a driver park there?

  1. No, because street cleaning restrictions apply every weekday
  2. Yes, because Wednesday is not a listed day Correct answer.
  3. Yes, but only for 15 minutes
  4. No, because the sign bars parking at all times

Explanation

The restriction applies only on the days and hours named, Monday and Thursday from 7 to 9 AM. Wednesday morning is outside those days, so parking is permitted unless another sign says otherwise. Drivers should read the day list carefully before leaving a vehicle.

Question 46Regulatory signs (speed limits, stop/yield, lane and turn controls, parking restrictions)

A white sign shows a black arrow pointing straight with ONLY beneath it, and a second sign beside it reads NO TRUCKS. A truck driver is in that lane. What must the driver do?

  1. Turn right at the intersection to leave the lane
  2. Change out of the lane and follow a route open to trucks Correct answer.
  3. Stop and wait for a police escort
  4. Continue straight because the lane requires it

Explanation

The lane marking requires through movement, but the NO TRUCKS sign bars trucks from that roadway or lane. The truck driver must leave the restricted lane and use a route where trucks are allowed. A lane-use arrow does not authorize a vehicle that is prohibited from the road.

Question 47Regulatory signs (speed limits, stop/yield, lane and turn controls, parking restrictions)

A white sign reads NO TURN ON RED, and the intersection also has a green right-turn arrow displayed. What should a driver wanting to turn right do?

  1. Treat the green arrow as permission and turn right without stopping Correct answer.
  2. Stop and turn right because the arrow is green
  3. Wait for a full green circle before turning
  4. Turn right only after yielding to cross traffic

Explanation

A green arrow is a protected signal that authorizes the indicated movement, and the no-turn-on-red rule governs turns made against a red signal. When the arrow is green, the driver may proceed in the arrow's direction. Stopping is not required when the movement has a green arrow.

Question 48Regulatory signs (speed limits, stop/yield, lane and turn controls, parking restrictions)

A driver passes a SPEED LIMIT 55 sign and later sees a white sign reading END 55 MPH ZONE. What does the second sign indicate?

  1. The maximum speed drops to 45 mph
  2. The posted 55 mph limit no longer applies and the default rule governs Correct answer.
  3. Drivers must now travel at least 55 mph
  4. The road becomes a construction zone

Explanation

An END sign marks the termination of the posted restriction, so the 55 mph limit stops applying at that point. The default statutory or subsequently posted limit then governs the road. Drivers should watch for the next speed limit sign to learn the current maximum.

Question 49Regulatory signs (speed limits, stop/yield, lane and turn controls, parking restrictions)

A white sign reads NO PARKING 6 PM TO 6 AM, and a driver arrives at 5:45 PM intending to leave at 6:30 PM. What is the correct understanding?

  1. Parking is allowed until 6 PM, then the vehicle would be in violation Correct answer.
  2. Parking is allowed if the driver stays in the vehicle
  3. Parking is barred from 5:45 PM because the restriction begins at dusk
  4. Parking is allowed the whole time because the stay is short

Explanation

The restriction takes effect at 6 PM, so a vehicle left past that time would be parked during the prohibited hours. A driver arriving at 5:45 PM may park only until the restriction begins. Staying with the vehicle does not exempt it from a no-parking rule.

Question 50Regulatory signs (speed limits, stop/yield, lane and turn controls, parking restrictions)

A white sign shows a left-turn arrow with ONLY, and a second sign reads NO LEFT TURN 7 AM TO 9 AM. A driver is in that lane at 8 AM. What is the correct action?

  1. Stop in the lane until 9 AM and then turn left
  2. Continue straight through the intersection from that lane
  3. Turn left because the lane marking requires it
  4. Leave the lane and follow a route that avoids the prohibited turn Correct answer.

Explanation

The time-based prohibition overrides the lane's turn requirement during the posted hours, so the driver cannot lawfully turn left at 8 AM. The driver should move out of the turn lane and reroute. Waiting in the lane until the restriction ends would obstruct traffic.
