Question 1Regulatory Signs

On Guam roads, a red octagonal sign with the word STOP means the driver must come to a complete stop at which point?

  1. Anywhere within 20 feet of the sign
  2. Only if another vehicle is approaching
  3. Only after checking that no police officer is watching
  4. At the stop line, crosswalk, or before entering the intersection Correct answer.

Explanation

A STOP sign requires a full halt at the marked stop line, at the crosswalk if one exists, or before the edge of the intersecting roadway when no markings are present. Rolling stops and stopping far back from the line do not satisfy the requirement.

Question 2Regulatory Signs

A red and white triangular sign with the word YIELD tells a driver approaching an intersection to do what?

  1. Stop completely for three seconds before proceeding
  2. Accelerate to merge ahead of cross traffic
  3. Slow down and give the right-of-way to traffic on the intersecting road Correct answer.
  4. Sound the horn before entering the intersection

Explanation

A YIELD sign requires the driver to slow and, if necessary, stop to let vehicles on the cross road pass before entering. A full stop is only required when traffic conditions demand it, not by rule.

Question 3Regulatory Signs

A white rectangular sign reading SPEED LIMIT 35 indicates which rule on a Guam roadway?

  1. 35 mph is a suggested speed for curves only
  2. 35 mph is the minimum speed a driver must maintain
  3. 35 mph is the maximum lawful speed in good conditions Correct answer.
  4. 35 mph applies only to trucks and buses

Explanation

A white speed limit sign sets the maximum lawful speed under favorable conditions. Drivers must still slow below that number when weather, visibility, or road conditions require it.

Question 4Regulatory Signs

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

  1. The left lane is reserved for passing
  2. A left curve is ahead and requires reduced speed
  3. Left turns are prohibited at this location Correct answer.
  4. Left turns are permitted only during daylight

Explanation

A red circle with a slash is the universal prohibition symbol, so a slashed left-turn arrow means no left turn. Warning signs for curves are yellow diamonds, which is a different shape and color.

Question 5Regulatory Signs

A white rectangular sign reading ONE WAY with an arrow indicates what about the street it faces?

  1. The street is closed to all motor vehicles
  2. Traffic alternates direction depending on the time of day
  3. Traffic on that street moves only in the direction of the arrow Correct answer.
  4. Only one lane of the street allows parking

Explanation

A ONE WAY sign marks a street or lane where all traffic must travel in the arrow's direction. Entering against the arrow is a violation and a common cause of head-on crashes.

Question 6Regulatory Signs

A white sign with a red circle and slash over a symbol of a bicycle means a bicyclist may not do what?

  1. Ride after dark without a light
  2. Ride on any public road on Guam
  3. Park a bicycle at a rack
  4. Ride in the area where the sign is posted Correct answer.

Explanation

The red circle and slash marks a prohibition, so the bicycle symbol means bicycles are excluded from that path, lane, or area. Bicycle lighting and parking rules are governed by other laws, not this sign.

Question 7Regulatory Signs

A yellow diamond sign showing a pedestrian figure indicates what ahead?

  1. A hospital entrance
  2. A school bus stop with no pedestrians
  3. A pedestrian crossing or walking area Correct answer.
  4. A closed sidewalk

Explanation

Yellow diamond signs are warnings, and the pedestrian symbol warns of people crossing or walking near the roadway ahead. Drivers should reduce speed and be ready to stop.

Question 8Regulatory Signs

A white rectangular sign reading DO NOT PASS with a red slash through a passing symbol means which action is prohibited?

  1. Driving in the left lane at any time
  2. Making a U-turn at the next intersection
  3. Overtaking another vehicle in that zone Correct answer.
  4. Exceeding the posted speed limit

Explanation

The DO NOT PASS sign with a slashed passing symbol establishes a no-passing zone where overtaking other vehicles is prohibited. It is often paired with solid yellow center lines.

Question 9Regulatory Signs

A driver approaches a four-way intersection where all approaches have STOP signs and arrives at the same moment as a vehicle on the right. Who should proceed first?

  1. Whichever driver honks first
  2. Whichever vehicle is larger
  3. The vehicle on the left
  4. The vehicle on the right Correct answer.

Explanation

At an all-way stop, vehicles proceed in the order they arrive, and simultaneous arrivals are resolved by yielding to the vehicle on the right. Size or assertiveness does not create right-of-way.

Question 10Regulatory Signs

A driver on Guam sees a red circle with a slash over a U-shaped arrow. What maneuver is prohibited?

  1. Changing lanes to the right
  2. Making a U-turn Correct answer.
  3. Turning right on red
  4. Backing into a driveway

Explanation

The slashed U-shaped arrow is the no U-turn symbol, meaning drivers may not reverse direction at that location. Right turns on red and lane changes are covered by other signs and rules.

Question 11Regulatory Signs

A white sign reading KEEP RIGHT with an arrow means a driver should do what?

  1. Turn right at the next intersection
  2. Always stay in the right lane for the entire trip
  3. Pass to the right of the median, island, or obstruction Correct answer.
  4. Yield to traffic coming from the right

Explanation

KEEP RIGHT directs traffic to pass on the right side of a median, traffic island, or other obstruction. It is a positioning instruction for that specific feature, not a general lane requirement.

Question 12Regulatory Signs

A yellow diamond sign with a black arrow bending sharply to the right and a smaller plaque reading 25 MPH tells the driver what?

  1. The road narrows to 25 feet ahead
  2. A curve ahead should be taken at or below the advisory speed Correct answer.
  3. The legal speed limit on the whole road is 25 mph
  4. Trucks must use a lower gear for 25 miles

Explanation

A yellow warning sign with an advisory speed plaque recommends a safe speed for the curve under good conditions. It is not the posted legal maximum for the road, though exceeding it in the curve may be unsafe or a violation of basic speed law.

Question 13Regulatory Signs

A white rectangular sign reading LEFT TURN ONLY is posted over a lane. What does this require of a driver in that lane?

  1. The driver may go straight if no traffic is present
  2. The driver must turn left from that lane Correct answer.
  3. The driver must merge right before the intersection
  4. The driver may turn left or make a U-turn

Explanation

A LEFT TURN ONLY sign designates the lane exclusively for left turns, so a driver who entered it must turn left. Going straight from a turn-only lane is a violation and can cause a collision.

Question 14Regulatory Signs

A white sign reading NO PARKING ANY TIME is posted along a curb. What does it mean for a driver?

  1. Parking is allowed for up to 15 minutes
  2. Parking is allowed if the driver remains in the car
  3. Parking is banned only during business hours
  4. The vehicle may not be left standing at the curb at any hour Correct answer.

Explanation

NO PARKING ANY TIME prohibits leaving a vehicle at the curb at all hours, regardless of business hours. Standing or waiting in a no-parking zone can still result in a citation.

Question 15Regulatory Signs

A red and white sign reading WRONG WAY is facing a driver. What should the driver do immediately?

  1. Speed up to clear the roadway quickly
  2. Stop and back out or turn around because the vehicle is facing opposing traffic Correct answer.
  3. Shift to the left lane and proceed
  4. Continue slowly with hazard lights on

Explanation

A WRONG WAY sign warns that the driver is entering a roadway against the direction of traffic, such as a one-way street or freeway ramp. The safe response is to stop as soon as possible and exit or turn around.

Question 16Regulatory Signs

A white sign with a red circle and slash over a symbol of a truck indicates what?

  1. Trucks may proceed only at night
  2. Trucks must reduce speed to 25 mph
  3. Trucks must use the left lane
  4. Trucks are prohibited from using that route Correct answer.

Explanation

The red circle and slash over a truck symbol prohibits trucks from the posted route or area. Weight and speed restrictions for trucks are shown on separate signs with explicit numbers.

Question 17Regulatory Signs

A driver is in a lane marked with a white diamond symbol and the word HOV. What does this sign require?

  1. The vehicle must meet the posted occupancy requirement to use the lane Correct answer.
  2. The lane is open only to vehicles with trailers
  3. The lane is reserved for emergency vehicles
  4. The vehicle must be a taxi or bus

Explanation

A diamond HOV marking designates a high-occupancy vehicle lane, which only vehicles meeting the posted occupant count may use. Signs nearby state the required number of people and the hours of operation.

Question 18Regulatory Signs

A white sign reading NO TURN ON RED is posted at an intersection. A driver who wants to turn right while the signal is red must do what?

  1. Turn if no pedestrians are visible
  2. Wait for a green signal before turning Correct answer.
  3. Turn after slowing to a rolling stop
  4. Turn after sounding the horn

Explanation

NO TURN ON RED removes the usual permission to turn right after stopping at a red light, so the driver must wait for a green indication. The sign overrides the general right-turn-on-red rule at that intersection.

Question 19Regulatory Signs

A yellow diamond sign showing a black arrow splitting into two directions ahead warns of what?

  1. A one-way street begins
  2. A pedestrian island is closed
  3. A divided highway or median will separate traffic Correct answer.
  4. A lane will end and merge left

Explanation

A split-arrow warning sign indicates that the roadway ahead divides, often around a median or island, and drivers must keep to one side. It is a warning of geometry, not a lane-closure instruction.

Question 20Regulatory Signs

A white rectangular sign reading NO LEFT TURN is posted at an intersection, and the driver intends to enter a driveway on the left just past the intersection. What must the driver do?

  1. Continue past and use a legal route such as a later U-turn or around the block Correct answer.
  2. Make the left turn because a driveway is not a street
  3. Make the left turn if no oncoming traffic is present
  4. Make the left turn after stopping completely

Explanation

A NO LEFT TURN sign prohibits the left-turn maneuver at that intersection, including turns into driveways immediately beyond it in most cases. The driver must find a legal alternative rather than treating a driveway as an exception.

Question 21Regulatory Signs

A driver sees a white sign reading ROAD CLOSED AHEAD with a detour arrow pointing right. What is the correct action?

  1. Stop and wait at the sign for the road to reopen
  2. Proceed ahead and move barricades if the road looks clear
  3. Turn around and drive against traffic to the last exit
  4. Follow the detour route rather than continuing toward the closure Correct answer.

Explanation

A ROAD CLOSED sign with a detour arrow directs traffic onto the designated alternate route. Ignoring the closure or moving barricades endangers workers and puts the driver in an unauthorized area.

Question 22Regulatory Signs

A white sign reading SPEED LIMIT 25 is posted near a Guam school zone, and a separate yellow plaque shows a flashing signal during school hours. How should a driver interpret the limit when the signal is flashing?

  1. The reduced limit applies during the posted school hours and requires extra caution for children Correct answer.
  2. The limit is advisory and may be exceeded if traffic is light
  3. The limit replaces all other speed laws on the island
  4. The limit applies only when children are visibly crossing the road

Explanation

A school zone speed sign with a flashing signal sets a reduced limit during the stated hours, and drivers must also watch for children near the roadway. The limit is enforceable during those hours even before a child steps into view.

Question 23Regulatory Signs

A driver approaches a sign reading NO PEDESTRIANS with a slashed walking figure on a bridge approach. Which statement best describes the rule?

  1. People on foot are excluded from that roadway section because of the hazard Correct answer.
  2. Pedestrians may use the shoulder but not the travel lane
  3. Pedestrians must wear reflective clothing to proceed
  4. Pedestrians may cross only at the far end of the bridge

Explanation

A NO PEDESTRIANS sign with a slashed walking figure excludes foot traffic from that section of roadway, typically because shoulders or walkways are absent. The restriction is absolute for that segment rather than conditional on clothing or position.

Question 24Regulatory Signs

A white sign reading TWO-WAY TRAFFIC AHEAD is posted after a divided highway ends. What risk should the driver anticipate?

  1. Oncoming vehicles will share the roadway, so passing and lane position must be adjusted Correct answer.
  2. The left lane will become a dedicated turning lane
  3. The speed limit will automatically drop to 15 mph
  4. The road will become one-way in the driver's direction

Explanation

A TWO-WAY TRAFFIC warning tells drivers that opposing traffic will soon share the road, often after a divided section ends. Drivers should move out of any lane meant for opposing traffic and avoid passing unless clearly permitted.

Question 25Regulatory Signs

A white rectangular sign shows a black arrow curving left and the words ONE WAY. A driver is facing the sign on a two-lane street. What does this sign tell the driver about traffic on that street?

  1. Traffic on the street must stop before entering the next block
  2. Traffic on the street must merge into the left lane ahead
  3. Traffic on the street may travel in either direction after the sign
  4. Traffic on the street moves only in the direction the arrow points Correct answer.

Explanation

A ONE WAY sign with an arrow shows the single permitted direction of travel for all traffic on that roadway. The arrow points along the legal flow, so a driver facing it knows that opposing traffic will not approach head-on.

Question 26Regulatory Signs

A white rectangular sign reads DO NOT ENTER, and the driver sees it facing the lane ahead. What does this sign mean for that lane?

  1. Entry is allowed only for vehicles turning right at the corner
  2. Entry is prohibited because traffic there comes toward the driver Correct answer.
  3. Entry is allowed after a complete stop and a check for traffic
  4. Entry is prohibited only during posted school hours

Explanation

DO NOT ENTER marks a roadway or lane where traffic moves toward the viewer, so driving into it would put the driver against the flow. The sign is regulatory and applies at all times, not only during certain hours.

Question 27Regulatory Signs

A driver reaches an intersection where a red signal is displayed and wants to make a right turn. A white sign beside the signal reads NO TURN ON RED. What must the driver do?

  1. Turn right only if a police officer signals
  2. Turn right after coming to a full stop
  3. Wait for a green signal before making the right turn Correct answer.
  4. Turn right after yielding to cross traffic

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 and the turn can be made lawfully.

Question 28Regulatory Signs

A white rectangular sign reads KEEP RIGHT with an arrow pointing down and to the right. What does the sign direct a driver to do?

  1. Turn right at the upcoming corner
  2. Move into the right lane before the next intersection
  3. Reduce speed and stay in the right lane
  4. Pass to the right side of the divider or obstacle Correct answer.

Explanation

KEEP RIGHT with a downward diagonal arrow tells drivers to pass on the right side of a median, island, or obstruction. It is a channeling sign placed where the correct path is not obvious.

Question 29Regulatory Signs

A white rectangular sign reads NO PARKING ANY TIME along a curb. What does this mean for a driver?

  1. The vehicle may park overnight only
  2. The vehicle may park for up to fifteen minutes
  3. The vehicle may stop briefly to load passengers
  4. The vehicle may not be left at the curb at any hour Correct answer.

Explanation

NO PARKING ANY TIME prohibits leaving a vehicle at the curb regardless of the hour or day. Brief stopping may be governed separately, but parking is never permitted there.

Question 30Regulatory Signs

A white sign shows a red circle with a diagonal slash over a symbol of a left-turning arrow. What does this sign prohibit?

  1. Making a left turn at that location Correct answer.
  2. Entering the left lane before the turn
  3. Making a U-turn farther ahead
  4. Driving straight through the intersection

Explanation

A red circle with a slash is the universal prohibition symbol, and the arrow inside shows the maneuver that is banned. Here the banned maneuver is a left turn at that point.

Question 31Regulatory Signs

A yellow diamond sign shows a black pedestrian figure walking within a crosswalk. What should a driver expect ahead?

  1. A sidewalk that ends and forces walkers onto the shoulder
  2. A school bus loading zone with stopped buses
  3. A path used only by bicyclists and skaters
  4. A marked crossing where pedestrians may be in the roadway Correct answer.

Explanation

A pedestrian warning diamond alerts drivers to a crossing area where people may enter the roadway. The driver should slow down and be ready to yield to anyone in the crosswalk.

Question 32Regulatory Signs

A white rectangular sign reads SPEED LIMIT 35. What does this sign establish for the road?

  1. The advised speed for the sharpest curve
  2. The speed required only during rain
  3. The maximum lawful speed under normal conditions Correct answer.
  4. The minimum speed a driver must maintain

Explanation

A white SPEED LIMIT sign with black numerals sets the maximum lawful speed on that road in good conditions. Driving faster than the posted number is a violation even if the driver feels the road could handle it.

Question 33Regulatory Signs

A white sign with a red circle and slash over a symbol of a truck is posted at the entrance to a residential street. What does the sign mean?

  1. Trucks must use the left lane on that street
  2. Trucks may enter only to make deliveries
  3. Trucks are prohibited from using that street Correct answer.
  4. Trucks must reduce speed on that street

Explanation

The red circle and slash cancel the symbol inside, so a slashed truck means trucks are not allowed on that roadway. Any delivery exception would have to be stated on an additional plaque.

Question 34Regulatory Signs

A driver is in a lane marked with a white diamond and the letters HOV. A sign beside the lane reads 2 OR MORE PERSONS PER VEHICLE. What does this require?

  1. At least two occupants must be in the vehicle while it uses the lane Correct answer.
  2. The driver must pay a toll before using the lane
  3. The lane may be used only during rush hour by any vehicle
  4. The vehicle must be a van or bus to use the lane

Explanation

A high-occupancy vehicle lane marked with a diamond requires the stated number of occupants during its restricted hours. A solo driver using the lane when the restriction is active commits a violation.

Question 35Regulatory Signs

A white rectangular sign reads NO LEFT TURN, but the driver needs to reach a driveway on the left just past the intersection. What is the proper action?

  1. Make the left turn slowly after checking for oncoming traffic
  2. Make the left turn only after the light turns green
  3. Signal and wait for a gap, then turn left
  4. Continue past and approach the driveway from a legal direction or turn Correct answer.

Explanation

NO LEFT TURN forbids the maneuver at that location no matter the destination. The driver must find a lawful route, such as continuing ahead and circling back or using a permitted turn.

Question 36Regulatory Signs

A white sign reading ROAD CLOSED AHEAD appears with a black detour arrow pointing right. What should the driver do?

  1. Continue straight and check whether the road is passable
  2. Stop and wait for the road to reopen
  3. Turn right only if a flagger waves the driver through
  4. Follow the arrow onto the designated detour route Correct answer.

Explanation

A ROAD CLOSED sign with a detour arrow directs traffic onto an alternate route around the closure. The driver should follow the marked detour rather than attempting to continue through the closed section.

Question 37Regulatory Signs

A white sign reads LEFT TURN ONLY above a lane at an intersection. What does this require of a driver who enters that lane?

  1. The driver may go straight if no traffic is present
  2. The driver must merge right before the intersection
  3. The driver must turn left when reaching the intersection Correct answer.
  4. The driver may turn left or continue straight

Explanation

A LEFT TURN ONLY sign assigns the lane exclusively to left-turning traffic. Once in the lane, a driver is expected to complete the left turn rather than proceed straight.

Question 38Regulatory Signs

A driver on a one-way street meets a white sign reading TWO-WAY TRAFFIC AHEAD. What risk should the driver anticipate?

  1. The speed limit will drop sharply beyond the sign
  2. The street will narrow to a single lane ahead
  3. Oncoming vehicles may appear in what had been a single-direction roadway Correct answer.
  4. A traffic signal will control the next intersection

Explanation

TWO-WAY TRAFFIC AHEAD warns that the road the driver is on will begin carrying opposing traffic. The driver should keep right and watch for vehicles approaching head-on after the change.

Question 39Regulatory Signs

A white rectangular sign reads WRONG WAY and faces a driver entering a ramp. What should the driver do?

  1. Sound the horn and keep moving forward
  2. Continue slowly with hazard lights on
  3. Stop and back out or turn around before continuing Correct answer.
  4. Proceed to the next exit and merge

Explanation

WRONG WAY means the driver is heading into lanes used by oncoming traffic, typically after entering an exit ramp. The safe response is to stop immediately and leave the roadway in a legal direction.

Question 40Regulatory Signs

A white sign shows a red circle and slash over a symbol of a bicycle. What does this sign mean for bicyclists?

  1. Bicycles must use the left side of the path
  2. Bicycles must walk their bikes across the area
  3. Bicycles may ride only during daylight hours
  4. Bicycles may not ride on that path or roadway Correct answer.

Explanation

The slashed bicycle symbol prohibits bicycle use of the facility it marks, such as a path or shoulder. Bicyclists must use another route rather than dismount and continue.

Question 41Regulatory Signs

A driver approaches a four-way intersection where every approach has a STOP sign, and two vehicles arrive at the same moment from different directions. Who should proceed first?

  1. The vehicle on the right has the right of way Correct answer.
  2. The vehicle that honks first has the right of way
  3. The vehicle going straight has the right of way
  4. The vehicle in the left lane has the right of way

Explanation

At an all-way stop, when vehicles arrive at the same time, the driver on the left yields to the driver on the right. Each driver must still stop fully and confirm the way is clear before moving.

Question 42Regulatory Signs

A white sign reading NO PEDESTRIANS with a slashed walking figure is posted at a bridge approach. Which statement is correct?

  1. People on foot may cross only when traffic is light
  2. People on foot are not permitted to cross there and should use another route Correct answer.
  3. People on foot may cross if accompanied by an adult
  4. People on foot may cross only on the sidewalk side

Explanation

A slashed pedestrian symbol prohibits walking on that section of roadway, often because no walkway exists. Pedestrians must find an alternate crossing rather than proceed along the bridge.

Question 43Regulatory Signs

A driver sees a white sign reading NO U-TURN at a median opening. What is the effect of this sign?

  1. The driver may make a U-turn if no sign prohibits left turns
  2. The driver may make a U-turn during off-peak hours
  3. The driver may make a U-turn after stopping
  4. The driver may not reverse direction at that opening Correct answer.

Explanation

NO U-TURN prohibits reversing direction at the location where the sign is posted, regardless of traffic conditions. The driver should continue to a place where a U-turn is permitted.

Question 44Regulatory Signs

A yellow diamond sign shows a black arrow bending sharply to the right, and a smaller yellow plaque below reads 25 MPH. How should the driver interpret the plaque?

  1. It is the minimum speed allowed through the curve
  2. It is an advised speed for the curve, not the posted legal limit Correct answer.
  3. It is the speed limit only when the pavement is wet
  4. It is the legal maximum speed for the entire road

Explanation

A yellow plaque beneath a curve warning gives an advisory speed judged safe for that curve under good conditions. It does not replace a white regulatory speed limit sign on the same road.

Question 45Regulatory Signs

A white sign reading SPEED LIMIT 25 stands near a Guam school, and a yellow plaque below it flashes when children are present. How should a driver treat the flashing plaque?

  1. Treat the flashing plaque as a signal to honk for children
  2. Maintain the normal road speed because yellow signs are advisory
  3. Stop completely before the school crossing at all times
  4. Slow to the posted school-zone limit while the plaque is flashing Correct answer.

Explanation

A flashing school-zone plaque indicates the reduced regulatory limit is in force while children are present. The driver must comply with the posted school-zone speed during the flashing period.

Question 46Regulatory Signs

A driver in a lane marked with a white diamond symbol sees the HOV restriction in force and is traveling alone. What is the correct action?

  1. Stay in the lane only if the vehicle is a hybrid
  2. Leave the lane before the restriction zone begins Correct answer.
  3. Stay in the lane and drive at the posted limit
  4. Stay in the lane and flash headlights at other drivers

Explanation

When the HOV restriction is active, a solo driver does not meet the occupancy requirement and must exit the lane before the restricted section. Remaining in the lane would be a violation regardless of speed.

Question 47Regulatory Signs

A white sign reading NO TURN ON RED is posted at an intersection, and a driver wants to turn right while the signal is red but a green arrow for the cross street is displayed. What should the driver do?

  1. Turn right after the vehicle ahead clears the corner
  2. Turn right because the cross street has a green arrow
  3. Remain stopped until the driver's own signal turns green Correct answer.
  4. Turn right after yielding to the cross-street traffic

Explanation

NO TURN ON RED bars the right turn while the driver's signal is red, even when cross traffic has a green arrow. The driver must wait for a green indication for their own approach.

Question 48Regulatory Signs

A white sign reading KEEP RIGHT with an arrow stands beside a raised median at a fork. A driver intends to bear left around the median. What does the sign require instead?

  1. Pass on the right side of the median Correct answer.
  2. Stop before the median and wait
  3. Merge into the left lane beyond the median
  4. Sound the horn before choosing a side

Explanation

KEEP RIGHT at a median directs traffic to pass on the right-hand side of the divider. Bearing left would put the driver on the wrong side of the raised median and into opposing flow.

Question 49Regulatory Signs

A driver on a divided highway passes a white sign reading TWO-WAY TRAFFIC AHEAD after the divider ends. What is the most important adjustment?

  1. Move to the left portion to leave room for merging traffic
  2. Turn on high beams to warn oncoming drivers
  3. Move to the right portion of the road and expect oncoming vehicles Correct answer.
  4. Increase speed to clear the transition quickly

Explanation

When a divided highway transitions to two-way operation, the driver should position to the right so oncoming traffic has the correct side. Anticipating head-on vehicles after the change is the key safety adjustment.

Question 50Regulatory Signs

A driver proceeding straight through an intersection passes a white rectangular sign mounted beside the road that reads DO NOT BLOCK INTERSECTION. What does this sign require of the driver?

  1. Stop fully before the stop line and wait for a green light before moving
  2. Yield to all cross traffic before entering, even when holding a green light
  3. Keep the center of the intersection clear for emergency vehicles only
  4. Enter the intersection only when there is room to clear it completely without stopping Correct answer.

Explanation

This regulatory sign tells drivers not to enter an intersection unless they can drive all the way through without stopping, so that cross traffic and turning vehicles are not trapped. It applies even when the signal is green, because a green light does not authorize a driver to stop in the middle of the box. The rule keeps the intersection open and prevents gridlock during heavy traffic.
