Question 1Regulatory Signs

On a two-lane road in Idaho, a solid yellow line appears on your side of the centerline. What does this require of you?

  1. Do not cross the line to pass another vehicle Correct answer.
  2. Pass freely if the road ahead is clear for at least 500 feet
  3. Sound your horn before passing and then cross the line
  4. Pass only when the vehicle ahead is a slow-moving farm tractor

Explanation

A solid yellow line on your side of the centerline marks a no-passing zone for traffic moving in your direction. You may not cross it to overtake another vehicle, though you may cross it when turning left into a driveway or side road where it is legal to do so.

Question 2Regulatory Signs

You approach a red octagonal sign at an intersection with no other traffic present. What must you do before proceeding?

  1. Yield only to vehicles already in the intersection
  2. Come to a complete stop, then proceed when safe Correct answer.
  3. Slow down and continue if the way is clear
  4. Stop only if a pedestrian is waiting to cross

Explanation

The octagonal red sign is the STOP sign, and it requires a full halt at the marked stop line or before entering the crosswalk or intersection. Rolling slowly through is not a legal stop, and the requirement applies even when no other traffic is visible.

Question 3Regulatory Signs

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

  1. A suggested speed for ideal conditions
  2. The speed required when towing a trailer
  3. The maximum lawful speed in good conditions Correct answer.
  4. The minimum speed allowed on the roadway

Explanation

A white speed limit sign with black numerals sets the maximum lawful speed for that stretch of road under favorable conditions. Driving faster than the posted number is unlawful, and driving substantially slower than surrounding traffic can also be hazardous.

Question 4Regulatory Signs

A sign shows a black arrow curving to the right inside a yellow diamond. How should you respond?

  1. Expect the right lane to end shortly
  2. Turn right at the next intersection
  3. Merge right into the adjacent lane
  4. Prepare for a curve ahead and reduce speed Correct answer.

Explanation

A yellow diamond is a warning sign, and a curved arrow inside it warns of a bend in the road ahead. The appropriate response is to slow before the curve and stay in your lane, not to treat the arrow as a turn instruction.

Question 5Regulatory Signs

What does a white rectangular sign reading ONE WAY with a right-pointing arrow tell you?

  1. Traffic on that street moves only in the arrow direction Correct answer.
  2. Parking is allowed only on the right side
  3. You must turn right at the next intersection
  4. The right lane is reserved for buses

Explanation

The ONE WAY sign indicates that all traffic on that roadway travels in the direction the arrow points. Entering such a street against the arrow is a serious hazard because oncoming drivers will not expect you.

Question 6Regulatory Signs

A red circle with a diagonal slash over a black left-turn arrow means what?

  1. Left turns are prohibited at this location Correct answer.
  2. Left turns are allowed after a complete stop
  3. Left turns are permitted only during green arrows
  4. The left lane is reserved for through traffic

Explanation

A red circle with a diagonal slash is the universal prohibition symbol, so this sign forbids left turns. You must use another route or a different intersection to make the turn.

Question 7Regulatory Signs

What shape and color identify a railroad crossing warning sign in advance of the tracks?

  1. A white rectangle with black lettering
  2. A yellow diamond with a round black X and RR letters Correct answer.
  3. A yellow circular sign with a black X
  4. A red triangle with a white border

Explanation

The advance railroad warning is a yellow diamond containing a black round X and the letters RR. It warns you to slow, look, and listen before reaching the tracks themselves.

Question 8Regulatory Signs

A downward-pointing red-and-white triangular sign requires you to do what?

  1. Stop completely before proceeding
  2. Merge into the left lane
  3. Slow down and give the right of way Correct answer.
  4. Yield only to vehicles on your right

Explanation

The inverted triangle is the YIELD sign. You must slow as needed and let traffic on the intersecting road go first, proceeding only when the way is clear.

Question 9Regulatory Signs

You are driving in the left lane of a multi-lane highway and see a slower vehicle ahead in your lane. A broken white line separates your lane from the lane to your right. What does the broken white line permit?

  1. Crossing only to make a left turn
  2. Crossing only during daylight hours
  3. No crossing at any time
  4. Crossing to change lanes when it is safe Correct answer.

Explanation

Broken white lines separate lanes of traffic moving in the same direction and may be crossed when a lane change can be made safely. They do not grant an absolute right to change lanes; you must still signal and check for other vehicles.

Question 10Regulatory Signs

A white sign shows a bicycle symbol inside a lane marked with a bicycle and chevron markings. What is the purpose of this configuration?

  1. It requires bicyclists to ride on the sidewalk
  2. It bans bicycles from the roadway
  3. It reserves the lane for parked bicycles only
  4. It designates a shared lane where bicyclists may use the full lane Correct answer.

Explanation

Shared lane markings, often called sharrows, alert drivers that bicyclists may occupy the travel lane and indicate where they should ride. Drivers should expect bicycles in that lane and pass only when it is safe to do so.

Question 11Regulatory Signs

A yellow diamond sign shows a pedestrian figure inside a diagonal slash. What does this sign communicate?

  1. A crosswalk has been permanently removed
  2. A school bus stop is ahead
  3. Pedestrians are prohibited from crossing here Correct answer.
  4. A pedestrian crossing is ahead

Explanation

Placing a pedestrian symbol inside a yellow warning diamond with a slash conveys that pedestrians are not permitted to cross at that location. Drivers should still watch for people who may not comply, but the sign itself prohibits crossing.

Question 12Regulatory Signs

You see a sign reading NO RIGHT TURN ON RED beneath a traffic signal. The light is red and no traffic is coming. What may you do?

  1. Turn right after stopping and checking for traffic
  2. Wait for the light to turn green before turning right Correct answer.
  3. Turn right without stopping if the way is clear
  4. Turn right only if a police officer waves you through

Explanation

The sign removes the usual permission to turn right after stopping at a red light. You must remain stopped until the signal turns green, then complete the turn when it is safe.

Question 13Regulatory Signs

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

  1. Straight-through traffic must yield
  2. The lane ends ahead and you must merge
  3. You must proceed straight from this lane Correct answer.
  4. You may turn if no traffic is present

Explanation

A lane-use sign with an arrow and the word ONLY means the lane is reserved for that single movement. If you are in this lane you must go straight, so choose a different lane well before the intersection if you intend to turn.

Question 14Regulatory Signs

A white sign with a red circle and slash covers a symbol of a truck. What is the most likely meaning at this location?

  1. Trucks must reduce speed here
  2. A truck weigh station is ahead
  3. Trucks must use the right lane
  4. Trucks are prohibited from this route Correct answer.

Explanation

The red circle with a diagonal slash marks a prohibition, so a slashed truck symbol means trucks are not allowed on that roadway. Such restrictions are often posted on parkways or residential streets with weight or clearance limits.

Question 15Regulatory Signs

You approach an intersection where a sign reads DO NOT BLOCK INTERSECTION. Traffic ahead is backed up through the crossing. What should you do?

  1. Proceed and rely on other drivers to let you through
  2. Enter the intersection and stop behind the last car
  3. Wait before the intersection until space is available Correct answer.
  4. Drive around the backup using the shoulder

Explanation

This sign reminds drivers not to enter an intersection unless they can clear it completely. Stopping in the middle blocks cross traffic and emergency vehicles, so you should wait behind the crossing until space opens.

Question 16Regulatory Signs

A yellow diamond sign depicts a traffic signal with a red light illuminated. What is the sign warning you about?

  1. You must stop at this sign
  2. A flashing yellow light is ahead
  3. The signal ahead is currently red
  4. A signal-controlled intersection is ahead Correct answer.

Explanation

This warning sign alerts drivers that a signalized intersection lies ahead, which matters especially when sight distance is limited or traffic is fast. It does not tell you the current color of the light, so you must still respond to the actual signal.

Question 17Regulatory Signs

A sign shows a black symbol of a car on a slippery-looking curved path inside a yellow diamond. What action does it call for?

  1. Turn on your high beams for visibility
  2. Increase speed to maintain traction
  3. Shift into neutral until the surface improves
  4. Reduce speed and avoid sudden braking or steering Correct answer.

Explanation

The slippery-when-wet warning tells you the pavement loses traction in wet conditions. The safe response is to slow down before the hazard and make gentle steering and braking inputs so the tires keep their grip.

Question 18Regulatory Signs

A white rectangular sign reads KEEP RIGHT. What does it direct you to do?

  1. Remain in the right lane for the next mile
  2. Yield to traffic on your right
  3. Turn right at the next corner
  4. Stay to the right of a median or traffic island Correct answer.

Explanation

KEEP RIGHT is a regulatory sign telling drivers to pass to the right side of a median, island, or obstruction. It is commonly placed where a divided road begins or where an object splits the roadway.

Question 19Regulatory Signs

A white sign with black lettering reads LEFT LANE MUST TURN LEFT. You are in that lane but want to go straight. What should you do?

  1. Stay in the lane and go straight when the light turns green
  2. Turn left and then make a U-turn to return
  3. Stop in the lane and wait for a gap to merge
  4. Change to a through lane before reaching the intersection Correct answer.

Explanation

Mandatory lane-use signs mean the lane is committed to the posted movement, so you must reposition before the intersection if you want to continue straight. Making the turn and improvising a return adds risk and delay.

Question 20Regulatory Signs

A sign shows a red circle with a slash over a symbol of a pedestrian and a diagonal arrow. What is the most reasonable interpretation?

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

Explanation

The slash-over-symbol design marks a prohibition, and pairing it with a pedestrian figure means people may not cross at that spot. Drivers should still scan for pedestrians who ignore the restriction, because they may step out anyway.

Question 21Regulatory Signs

A yellow diamond sign shows a black arrow bent at a right angle pointing left, with a small speed plate reading 25 MPH below it. How should you use the advisory speed?

  1. Use it as a recommended speed for the curve in good conditions Correct answer.
  2. Ignore it because only white signs are enforceable
  3. Treat it as the legal maximum for the curve
  4. Apply it only when the pavement is wet

Explanation

An advisory speed plate on a yellow warning sign suggests a safe speed for the curve under favorable conditions. It is not the posted legal limit, but exceeding it when the curve is sharp or the road is wet raises rollover and run-off risk.

Question 22Regulatory Signs

A white sign reads NO PARKING ANY TIME, and you see a broken yellow curb line painted along the edge. What is the effect of these combined markings?

  1. Parking is barred at all hours along that curb Correct answer.
  2. Parking is allowed briefly to load passengers
  3. Parking is allowed on weekends only
  4. Parking is allowed if you remain in the vehicle

Explanation

The sign states a permanent no-parking rule, and the yellow curb marking reinforces that restriction along the painted edge. Neither the sign nor the marking creates an exception for brief stops or weekend parking.

Question 23Regulatory Signs

You are on a road with a two-way left-turn lane marked by solid yellow lines on the outside and broken yellow lines on the inside. What is this lane for?

  1. Emergency vehicle use only
  2. Left turns from either direction, not for travel Correct answer.
  3. Through traffic during peak hours
  4. Passing slower traffic in either direction

Explanation

The center two-way left-turn lane is shared by traffic from both directions solely for making left turns into driveways or side streets. It is not a passing lane or a travel lane, and drivers should enter it only shortly before turning.

Question 24Regulatory Signs

A yellow diamond sign warns of a reduced-speed zone ahead with a black symbol of a curve and the legend 40 MPH. The posted regulatory limit is 55 MPH. Which statement best describes your obligation?

  1. You may keep 55 MPH because the yellow sign is only a warning
  2. You may exceed 55 MPH to pass before the zone begins
  3. You should slow toward 40 MPH before the hazard, and 55 remains the legal maximum elsewhere Correct answer.
  4. You must drive exactly 40 MPH through the entire zone

Explanation

Yellow warning signs with advisory speeds do not change the legal maximum, which stays at the white regulatory posting. They do, however, identify a hazard where a lower speed is prudent, and a driver who crashes while ignoring the advisory may face a speed-too-fast-for-conditions finding.

Question 25Regulatory Signs

A white sign shows a black arrow pointing down and to the left beside a raised median. Traffic in the left lane is moving in the opposite direction. What does the sign require?

  1. Keep to the right of the median Correct answer.
  2. Turn left across oncoming traffic
  3. Merge left after the median ends
  4. Yield to traffic in the left lane

Explanation

A downward-left arrow beside a median is a keep-right style directive telling you to pass on the right side of the divider. Crossing to the left of the median would put you into opposing traffic.

Question 26Regulatory Signs

A white rectangular sign with black lettering reads SPEED LIMIT 45. What does this sign establish at this location?

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

Explanation

A white regulatory speed limit sign with black numerals sets the maximum lawful speed for that road segment under normal conditions. It is enforceable, unlike yellow warning signs that merely advise. Drivers must not exceed the posted number unless a lower limit or condition applies.

Question 27Regulatory Signs

You see a white sign reading WRONG WAY with red lettering facing you at a ramp entrance. What does this indicate?

  1. A detour route begins at this point
  2. The ramp is closed to trucks only
  3. You are entering a one-way road against the flow of traffic Correct answer.
  4. The road ahead has a reduced speed zone

Explanation

WRONG WAY signs are placed facing traffic that has entered a one-way road or ramp in the wrong direction. Seeing one means you are traveling against the intended flow and must stop and turn around safely. They often appear with a DO NOT ENTER sign at the same location.

Question 28Regulatory Signs

A red octagon with the word STOP is posted at an intersection. What does this sign require of you?

  1. Stop only when other traffic is present
  2. Slow to about 10 mph and continue if clear
  3. Yield only to vehicles already in the intersection
  4. Come to a complete stop before proceeding when safe Correct answer.

Explanation

The red octagon is the only shape used for STOP signs in the United States, and it requires a full stop at the marked line or before entering the crosswalk. You then proceed only when it is safe. Rolling stops do not satisfy the requirement.

Question 29Regulatory Signs

A white rectangular sign reads YIELD with a downward-pointing red triangle symbol. What action does this sign call for?

  1. Increase speed to clear the intersection quickly
  2. Slow and give the right of way to cross traffic, stopping if needed Correct answer.
  3. Come to a complete stop in every case before proceeding
  4. Merge without slowing because cross traffic must yield

Explanation

A yield sign requires you to slow down and give the right of way to traffic on the intersecting road. You must stop if necessary to avoid conflict, but a full stop is not always mandatory. The downward triangle shape distinguishes it from a stop sign.

Question 30Regulatory Signs

A white sign with black lettering reads ONE WAY with an arrow pointing right. What does it tell you?

  1. Right turns are prohibited at the next intersection
  2. The road ahead becomes a divided highway
  3. The right lane is reserved for buses
  4. Traffic on that road moves only in the direction of the arrow Correct answer.

Explanation

ONE WAY signs indicate that all traffic on the roadway flows in the direction shown by the arrow. You may travel that direction but must not drive against it. These signs commonly appear at intersections with one-way streets.

Question 31Regulatory Signs

A square white sign with a red circle and slash over a black U-shaped arrow means what?

  1. The road makes a U-shaped curve ahead
  2. U-turns are prohibited at this location Correct answer.
  3. A U-turn lane is ahead on the left
  4. Only trucks may make U-turns here

Explanation

A red circle with a diagonal slash over a black symbol is the standard prohibition format. A U-shaped arrow inside it means U-turns are not allowed at that location. The sign is regulatory and enforceable.

Question 32Regulatory Signs

A white sign reads NO PARKING with a red circle and slash over a letter P. What does this sign mean?

  1. You must not stop for any reason, including to drop off a passenger
  2. You may stop briefly to load passengers but may not leave the vehicle parked Correct answer.
  3. Parking is allowed only for delivery vehicles
  4. You may park for up to 15 minutes at any time

Explanation

NO PARKING prohibits leaving a vehicle unattended or standing in the space, while a brief stop to load or unload passengers is generally allowed unless signs say NO STOPPING. The distinction matters for enforcement. A NO STOPPING sign would forbid even momentary stops.

Question 33Regulatory Signs

A yellow diamond sign with black lettering reads SCHOOL ZONE and shows a pedestrian symbol. What does it alert you to?

  1. Children may be present and lower speeds may apply during school hours Correct answer.
  2. The road is closed during school hours
  3. School buses must use the shoulder
  4. Pedestrians are prohibited in this area

Explanation

SCHOOL ZONE signs warn of children crossing and often accompany reduced speed limits during posted hours. Drivers should slow down and watch carefully for students. The yellow diamond shape marks it as a warning sign.

Question 34Regulatory Signs

You approach a four-way intersection where all approaches have STOP signs. Two vehicles arrive at the same moment, one on your right. Who has the right of way?

  1. The vehicle on your right Correct answer.
  2. The vehicle turning left
  3. Whichever vehicle is larger
  4. You, because you arrived first

Explanation

At a four-way stop where vehicles arrive at the same time, the driver on the left yields to the driver on the right. This rule resolves ties when no one clearly arrived first. After stopping, you proceed only when the way is clear.

Question 35Regulatory Signs

A white sign reads NO TURN ON RED beneath a signal. The light is red and the cross street is empty. What must you do?

  1. Wait for a green light before turning Correct answer.
  2. Proceed through the red light carefully
  3. Turn right after stopping because the way is clear
  4. Turn left after yielding to pedestrians

Explanation

NO TURN ON RED overrides the general permission to turn right on red after a stop. Even with no cross traffic, you must wait for a green signal before turning. Turning anyway is a violation.

Question 36Regulatory Signs

A white sign reads LEFT LANE MUST TURN LEFT. You are in that lane but want to continue straight. What is the best action?

  1. Stay in the lane and go straight when clear
  2. Turn left and then make a U-turn to return
  3. Change to a through lane before reaching the intersection Correct answer.
  4. Stop in the lane and wait for a gap

Explanation

A mandatory turn sign requires vehicles in that lane to turn as directed. If you intend to go straight, you must move to a through lane before the intersection. Stopping or going straight in a turn-only lane disrupts traffic and is unsafe.

Question 37Regulatory Signs

A white rectangular sign reads KEEP RIGHT with an arrow. A raised median divides the road ahead. What should you do?

  1. Stop before the median and wait
  2. Drive to the left of the median
  3. Turn around before the median
  4. Stay to the right of the median Correct answer.

Explanation

KEEP RIGHT directs traffic to pass to the right side of a median, island, or obstacle. It is a regulatory sign and should be obeyed to avoid driving into the divider. The arrow reinforces the intended path.

Question 38Regulatory Signs

A white sign reads DO NOT BLOCK INTERSECTION. Traffic ahead is backed up through the crosswalk. What should you do?

  1. Drive around the backup using the shoulder
  2. Sound your horn until traffic moves
  3. Enter the intersection and stop in the middle
  4. Wait behind the crosswalk until there is room to clear the intersection Correct answer.

Explanation

DO NOT BLOCK INTERSECTION reminds drivers to enter only when they can fully clear the intersection. Stopping in the box blocks cross traffic and pedestrians. Waiting behind the crosswalk keeps the intersection open.

Question 39Regulatory Signs

A white sign shows a black arrow pointing down and to the left beside a raised median. Traffic in the left lane is moving toward you. What does the sign indicate?

  1. The left lane is a passing lane
  2. Keep to the right of the median Correct answer.
  3. Merge left into oncoming traffic
  4. U-turns are permitted ahead

Explanation

A downward-left arrow beside a median typically directs traffic to keep right of the divider. It warns that the left side is for opposing traffic. Following the arrow keeps you in the correct lane.

Question 40Regulatory Signs

A white sign reads REDUCED SPEED ZONE AHEAD with a posted 35 MPH plate. You are currently in a 55 MPH zone. When does the 35 MPH limit take effect?

  1. Only at night
  2. Immediately upon seeing the sign
  3. Only when workers are present
  4. At the point where the reduced speed sign is posted Correct answer.

Explanation

A reduced speed zone sign establishes the lower limit beginning at the sign's location. Drivers should slow before reaching it so they are at or below 35 MPH when they pass it. The limit applies until a sign ends or changes it.

Question 41Regulatory Signs

A white sign reads NO RIGHT TURN with a red circle and slash over a right-turn arrow. You want to turn right into a driveway just past the corner. What should you do?

  1. Turn right anyway because it is a driveway, not a street
  2. Continue past the intersection and use a legal route to the driveway Correct answer.
  3. Turn right only if a police officer waves you through
  4. Turn right after stopping and yielding

Explanation

A NO RIGHT TURN sign prohibits the maneuver at that intersection regardless of the destination. Turning into a nearby driveway still requires making the prohibited turn. You must find a legal route.

Question 42Regulatory Signs

A white sign reads TRUCKS USE LOW GEAR on a steep downgrade. Why is this sign posted?

  1. To keep trucks in the right lane only
  2. To require trucks to stop at the bottom
  3. To help trucks control speed using engine braking Correct answer.
  4. To prevent trucks from using the grade

Explanation

On long downgrades, trucks can lose braking effectiveness from overheating. Using a low gear lets engine braking help control speed. The sign is a safety measure for heavy vehicles.

Question 43Regulatory Signs

A white sign shows a bicycle symbol with the legend SHARE THE ROAD. What does this sign communicate?

  1. A bike lane begins in 500 feet
  2. Only bicycles may use the right lane
  3. Bicycles are prohibited on this road
  4. Bicyclists may use this roadway and drivers should allow space Correct answer.

Explanation

SHARE THE ROAD signs remind drivers that bicyclists have a right to use the roadway. Drivers should give them adequate clearance and pass safely. The sign does not create a dedicated bike lane.

Question 44Regulatory Signs

A white sign reads NO PASSING ZONE with a black symbol of two cars. What does this sign mean?

  1. Passing other vehicles is prohibited in this area Correct answer.
  2. Only trucks may pass here
  3. Passing is allowed only at night
  4. You may pass if the road is clear

Explanation

NO PASSING ZONE signs mark the beginning of a section where passing is not allowed, usually because of limited sight distance. They correspond to solid yellow center lines. Passing is prohibited regardless of whether traffic appears clear.

Question 45Regulatory Signs

A white sign reads STOP HERE ON RED with a line marking the stop point. Where must you stop?

  1. Anywhere within the crosswalk
  2. At the next intersection after the signal
  3. At the marked line before the signal Correct answer.
  4. At the far side of the intersection

Explanation

STOP HERE ON RED signs indicate the precise point where vehicles must stop when the signal is red. Stopping at the marked line keeps crosswalks and intersections clear. Stopping beyond the line can obstruct pedestrians and cross traffic.

Question 46Regulatory Signs

A white sign with a red circle and slash over a symbol of a truck is posted on a residential street. What is the most likely meaning?

  1. A truck weigh station is ahead
  2. Trucks must reduce speed to 25 MPH
  3. Through trucks are prohibited on this street Correct answer.
  4. Trucks must use the left lane

Explanation

A red circle with a slash over a truck symbol prohibits trucks from using that roadway, often to keep heavy vehicles off residential streets. Local deliveries may be allowed under separate rules, but through truck traffic is barred. The sign is regulatory.

Question 47Regulatory Signs

A white sign reads NO U-TURN, and a second plate below reads EXCEPT BUSES. You are driving a passenger car. What does the combination mean for you?

  1. You may not make a U-turn here, but buses may Correct answer.
  2. No vehicle, including buses, may make a U-turn
  3. You may make a U-turn only during daylight
  4. You may make a U-turn because the exception applies broadly

Explanation

The main sign prohibits U-turns, and the exception plate limits that prohibition by allowing buses to make them. Exceptions apply only to the class named. A passenger car driver must still obey the prohibition.

Question 48Regulatory Signs

A white sign reads SPEED LIMIT 55, and below it a plate reads MINIMUM 40. What do the two signs together require?

  1. Drive no faster than 40 MPH
  2. Drive between 40 and 55 MPH under normal conditions Correct answer.
  3. Drive exactly 55 MPH at all times
  4. Drive at least 55 MPH

Explanation

The upper sign sets the maximum lawful speed and the plate sets a minimum. Together they create a range within which traffic should operate under normal conditions. Driving far below the minimum can impede traffic and is also a violation.

Question 49Regulatory Signs

A white sign reads RIGHT LANE ENDS and shows a merge arrow. Traffic is heavy and a vehicle is beside you in the left lane. What is the safest response?

  1. Maintain speed and force the other driver to yield
  2. Brake sharply and stop in the ending lane
  3. Adjust speed to merge behind or ahead of the other vehicle Correct answer.
  4. Move onto the shoulder to continue past the merge

Explanation

When your lane ends, you must merge into the continuing lane. Adjusting speed to fit into a gap is safer than forcing the issue. Stopping in a lane that ends or driving on the shoulder creates new hazards.

Question 50Regulatory Signs

A white sign reads NO PARKING 8 AM TO 6 PM with an arrow pointing left. You park at 7 PM on the left side of the sign. What is your status?

  1. You must move the vehicle by 8 AM or be cited immediately
  2. You may park only if you remain in the vehicle
  3. You are parked illegally because the arrow extends the restriction
  4. Parking is allowed because the restriction has ended for the day Correct answer.

Explanation

Time-limited parking signs apply only during the posted hours, and the arrow shows which direction the restriction covers. At 7 PM the restriction has expired for the day, so parking is permitted. The arrow does not extend the hours.
