Question 1Regulatory Signs

A red octagonal sign at an intersection tells a driver to do what?

  1. Yield to traffic on the right
  2. Slow down only if traffic is present
  3. Come to a complete stop Correct answer.
  4. Reduce speed to 25 mph

Explanation

The eight-sided red sign is the universal stop sign in Arizona. A driver must bring the vehicle to a full halt at the marked stop line or before entering the crosswalk, then proceed only when it is safe. Rolling slowly through the sign does not satisfy the requirement.

Question 2Regulatory Signs

What shape and color identify a yield sign in Arizona?

  1. A downward-pointing red-and-white triangle Correct answer.
  2. A yellow diamond
  3. A red octagon
  4. A white rectangle with black letters

Explanation

Yield signs are shaped as an inverted triangle with a red border and white center. The unique shape lets drivers recognize the sign even when its face is obscured by snow, dirt, or glare. At such a sign you must slow and give the right-of-way to crossing or approaching traffic.

Question 3Regulatory Signs

A white rectangular sign with black lettering reading SPEED LIMIT 45 indicates what?

  1. The minimum speed for the roadway
  2. The speed required during rain
  3. The maximum lawful speed in good conditions Correct answer.
  4. A suggested comfortable speed

Explanation

Posted speed limits set the maximum lawful speed under favorable conditions. Driving faster than the posted number is a violation even if the road seems clear. When weather or traffic is poor, drivers must slow below the limit to stay safe.

Question 4Regulatory Signs

A yellow diamond-shaped sign is generally used to do what?

  1. Warn drivers of a road condition ahead Correct answer.
  2. State a legal requirement with which drivers must comply
  3. Mark a parking restriction
  4. Give directions to a nearby city

Explanation

Yellow diamond signs are warning signs that alert drivers to hazards or changes ahead, such as curves, intersections, or narrowing lanes. They do not themselves impose a legal command the way a white regulatory sign does. Drivers should slow and prepare to respond to the condition shown.

Question 5Regulatory Signs

A sign showing a black arrow curving to the left inside a yellow diamond warns of what?

  1. A left turn is prohibited
  2. A one-way street begins
  3. A curve to the left ahead Correct answer.
  4. A lane must turn left

Explanation

A yellow diamond containing a curving arrow is a warning sign for a curve ahead in the direction shown. It advises drivers to reduce speed before reaching the bend. It does not forbid or require any turn.

Question 6Regulatory Signs

What does a red circle with a diagonal slash over a black symbol mean?

  1. The action shown is permitted only at night
  2. The action shown is recommended
  3. The action shown is required
  4. The action shown is prohibited Correct answer.

Explanation

A red circle with a diagonal slash is the standard prohibition symbol. Whatever symbol appears inside the circle is forbidden, such as a turn, a U-turn, or parking. Drivers must not perform the depicted action at that location.

Question 7Regulatory Signs

A white sign with the word ONLY beneath a left-turn arrow means what?

  1. Left turns are forbidden
  2. Left turns are allowed after stopping
  3. The lane may be used for through traffic
  4. Only left turns may be made from that lane Correct answer.

Explanation

A turn arrow combined with the word ONLY designates a dedicated lane. Drivers in that lane must make the indicated turn and may not continue straight. Entering such a lane intending to go straight can cause a collision with turning traffic.

Question 8Regulatory Signs

A red-and-white sign reading DO NOT ENTER is placed where?

  1. At a railroad crossing
  2. At the entrance to a school zone
  3. At the start of a passing zone
  4. At the exit of a one-way street facing wrong-way drivers Correct answer.

Explanation

DO NOT ENTER signs are mounted where traffic would be entering against the legal flow, such as the far end of a one-way street. They warn drivers that proceeding would put them head-on into oncoming traffic. The sign is often paired with a wrong-way arrow.

Question 9Regulatory Signs

A white rectangular sign reading ONE WAY with an arrow indicates what?

  1. Traffic may travel in either direction
  2. Traffic moves only in the direction of the arrow Correct answer.
  3. The road ends ahead
  4. Parking is allowed on one side only

Explanation

The ONE WAY sign tells drivers that all traffic on that roadway flows in the direction of the arrow. Entering against the arrow is illegal and dangerous. Drivers should check the arrow before turning onto the street.

Question 10Regulatory Signs

A driver approaches a four-way intersection where all directions have stop signs. After stopping, who has the right-of-way?

  1. The driver traveling fastest
  2. The driver in the largest vehicle
  3. The driver who arrives first Correct answer.
  4. The driver on the left

Explanation

At a multi-way stop, the first vehicle to come to a complete stop has the right to proceed first. If two vehicles stop at the same time, the driver on the left yields to the driver on the right. Vehicle size and speed do not determine priority.

Question 11Regulatory Signs

A sign reading NO RIGHT TURN ON RED is posted at an intersection. What must a driver do when the light is red and they want to turn right?

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

Explanation

The sign overrides the general permission to turn right on red. Where it is posted, the driver must remain stopped until the signal turns green. Yielding or checking for pedestrians does not create an exception.

Question 12Regulatory Signs

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

  1. Parking is banned only during business hours
  2. Parking is prohibited at all hours Correct answer.
  3. Parking is allowed for vehicles with permits
  4. Parking is allowed briefly to load passengers

Explanation

NO PARKING ANY TIME prohibits leaving a vehicle at the curb at all hours and on all days. Stopping briefly to load or unload may be treated differently from parking, but leaving the vehicle unattended is not allowed. Drivers should find a lawful space elsewhere.

Question 13Regulatory Signs

A white sign with a red border reading WRONG WAY is most likely encountered by a driver who has done what?

  1. Parked in a loading zone
  2. Entered a one-way street against traffic Correct answer.
  3. Driven past a railroad crossing
  4. Missed a school zone speed limit

Explanation

WRONG WAY signs face drivers who are traveling against the legal direction of a one-way road or ramp. Seeing one means the driver has entered the roadway incorrectly and should stop and back out safely. Continuing forward risks a head-on collision.

Question 14Regulatory Signs

A yellow diamond sign shows a pedestrian symbol. How should a driver respond?

  1. Watch for pedestrians and be ready to stop Correct answer.
  2. Accelerate to clear the area quickly
  3. Change lanes immediately regardless of traffic
  4. Sound the horn continuously

Explanation

A pedestrian warning sign alerts drivers to a crossing or walking area ahead. The safe response is to reduce speed, scan both sides of the road, and prepare to stop for anyone in the roadway. Arizona law requires drivers to yield to pedestrians in crosswalks.

Question 15Regulatory Signs

A black-and-yellow circular sign with an X and two R letters marks what?

  1. A four-way stop
  2. A school crossing
  3. A hospital zone
  4. A railroad crossing ahead Correct answer.

Explanation

The round yellow sign with a black X and the letters RR is the railroad advance warning sign. It tells drivers a crossing is ahead and that they should slow, look, and listen. Drivers must never stop on the tracks.

Question 16Regulatory Signs

A white sign reading KEEP RIGHT is placed at a traffic island. What action does it require?

  1. Pass the island on its right side Correct answer.
  2. Yield to traffic entering from the right
  3. Turn around at the island
  4. Stop before the island

Explanation

KEEP RIGHT directs drivers to pass to the right of a median, island, or obstruction. It keeps traffic flowing on the correct side and prevents wrong-way movement around the barrier. Drivers should follow the arrow or sign position rather than cutting to the left.

Question 17Regulatory Signs

A sign reading NO U-TURN is posted at a median opening. What does it prohibit?

  1. Changing lanes near the median
  2. Right turns at the intersection
  3. Reversing direction within the opening Correct answer.
  4. Left turns into driveways

Explanation

A U-turn reverses the vehicle's direction of travel. The NO U-TURN sign forbids that maneuver at the posted location, often because sight distance or traffic flow makes it unsafe. Drivers who need to reverse direction should continue to a lawful intersection.

Question 18Regulatory Signs

A white sign reading YIELD HERE TO PEDESTRIANS is posted at a crosswalk. What is the driver's obligation?

  1. Stop only if a pedestrian is already in the driver's lane
  2. Honk so pedestrians hurry across
  3. Slow and give way to pedestrians using the crossing Correct answer.
  4. Proceed because pedestrians must yield to vehicles

Explanation

The sign reinforces the driver's duty to yield to pedestrians in the crosswalk. Arizona law requires drivers to stop and remain stopped for a pedestrian crossing the roadway within a crosswalk. Waiting only for pedestrians in your own lane ignores the legal duty.

Question 19Regulatory Signs

A white regulatory sign shows a bicycle symbol inside a lane marking with the word ONLY. What does it indicate?

  1. The lane is reserved for bicycle use Correct answer.
  2. Bicycles are prohibited from the lane
  3. Motor vehicles may park in the lane
  4. Bicycles must ride on the sidewalk

Explanation

A bicycle symbol with ONLY marks a lane reserved for cyclists. Motor vehicles may not travel in or block such a lane except where turning movements are specifically permitted. Drivers should check for cyclists before crossing a bike lane.

Question 20Regulatory Signs

A yellow diamond sign reading SLOW TRAFFIC AHEAD with a symbol of queued vehicles warns of what?

  1. Stopped or slow-moving traffic ahead Correct answer.
  2. A mandatory speed reduction
  3. A construction zone with flaggers
  4. A lane closure for parking

Explanation

This warning sign alerts drivers that traffic ahead may be stopped or moving slowly, often beyond a crest or curve. Drivers should reduce speed and increase following distance. Reacting late to a queue is a common cause of rear-end crashes.

Question 21Regulatory Signs

A driver sees a white sign reading NO PASSING ZONE paired with a solid yellow line on their side. What does this combination mean?

  1. Passing is allowed only at night
  2. Passing is prohibited in that direction Correct answer.
  3. Passing is allowed only for trucks
  4. Passing is permitted when the road is clear

Explanation

A NO PASSING ZONE sign and a solid yellow line on the driver's side both prohibit passing in that direction. The restriction usually exists because of limited sight distance or a hazard. Drivers must wait until the marking and sign permit passing again.

Question 22Regulatory Signs

A white sign reading LEFT LANE MUST TURN LEFT is posted above a left lane. A driver in that lane who wants to continue straight should do what?

  1. Stop in the lane and wait for a green arrow
  2. Change to a through lane before the intersection Correct answer.
  3. Stay in the lane and proceed straight carefully
  4. Turn left and then make a U-turn

Explanation

The sign makes the left turn mandatory for that lane, so a driver intending to go straight must move to a through lane beforehand. Remaining in the lane and proceeding straight would violate the sign and conflict with turning traffic. Lane changes should be made early with proper signals and mirror checks.

Question 23Regulatory Signs

A sign reading NO TURN ON RED is posted at an intersection where the driver intends to turn left from a one-way street onto another one-way street. What applies?

  1. The driver may turn left on red only at night
  2. The driver must wait for a green light Correct answer.
  3. The driver may turn left on red after stopping
  4. The driver may turn left on red if no cars are visible

Explanation

The posted sign prohibits turns on red at that intersection, overriding any general permission that might otherwise apply. The driver must stop and wait for a green signal before turning. Absence of visible traffic does not create an exception to a posted regulatory sign.

Question 24Regulatory Signs

A white sign reading ROAD CLOSED is posted across a highway beyond a barricade. What is the lawful and safe response?

  1. Proceed slowly with hazard lights on
  2. Drive around the barricade if the road looks clear
  3. Wait at the barricade until another driver passes
  4. Turn around and use an alternate route Correct answer.

Explanation

A ROAD CLOSED sign means the roadway is not available for travel, often because of construction, flooding, or damage. Driving around barricades is illegal and dangerous because conditions beyond may be unsafe or unmarked. The correct action is to turn around and find another route.

Question 25Regulatory Signs

A white sign reading SPEED LIMIT 65 is posted, and a separate yellow sign below reads ADVISORY SPEED 45 on a curve ramp. How should the driver interpret the two numbers?

  1. Both numbers are legal maximums
  2. 45 is the legal maximum on the ramp
  3. 65 is the legal maximum and 45 is a recommended safe speed for the curve Correct answer.
  4. Neither number is enforceable

Explanation

The white speed limit sign sets the enforceable maximum for the roadway. The yellow advisory plaque recommends a lower speed that is safe for the specific curve or ramp geometry. Drivers who exceed the advisory speed may lose control even while staying under the posted limit.

Question 26Regulatory Signs

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

  1. The speed required during rain
  2. The minimum speed for all traffic
  3. The maximum lawful speed in good conditions Correct answer.
  4. A suggested speed for curves only

Explanation

A white sign with black numerals showing SPEED LIMIT states the maximum lawful speed for that road under normal conditions. Drivers may travel slower when conditions demand, but exceeding the posted number is a violation.

Question 27Regulatory Signs

A red-and-white sign reads STOP. Where must the vehicle come to a complete halt?

  1. Directly beside the sign pole regardless of markings
  2. Only after checking that no traffic is visible
  3. Anywhere within ten feet of the sign post
  4. At the stop line, crosswalk, or edge of the intersection Correct answer.

Explanation

A stop sign requires a complete halt at the marked stop line. If no line exists, the driver stops at the crosswalk, and if neither is present, at the edge of the intersecting roadway where visibility is adequate.

Question 28Regulatory Signs

A white sign with a red circle and the number 25 inside is posted near a school. What does it indicate?

  1. A 25 foot following distance requirement
  2. A 25 minute parking limit at the curb
  3. A minimum speed of 25 mph on the road
  4. A 25 mph maximum speed while the restriction is in effect Correct answer.

Explanation

A white regulatory sign with a red circle around a numeral is a speed limit sign, here setting a 25 mph maximum. Such signs near schools are often paired with flashing beacons or time plates that define when the lower limit applies.

Question 29Regulatory Signs

A sign shows a black arrow curving to the right inside a white square with a red circle and slash. What does it mean?

  1. Right turns are prohibited at this location Correct answer.
  2. Right turns are allowed only for buses
  3. The road curves sharply to the right ahead
  4. Right turns are permitted after stopping

Explanation

A red circle with a diagonal slash over a black symbol is the universal prohibition marking. When the symbol is a right-turn arrow, the sign forbids making a right turn at that point.

Question 30Regulatory Signs

A white sign reads PEDESTRIAN CROSSING with a walking figure. How does this regulatory sign differ from a yellow pedestrian warning sign?

  1. It prohibits pedestrians from crossing at that spot
  2. It marks a legal crosswalk where pedestrians have the right of way Correct answer.
  3. It tells drivers to sound the horn before proceeding
  4. It warns of pedestrians who may appear far ahead

Explanation

White signs are regulatory and state a rule that must be obeyed, so a white pedestrian crossing sign identifies a legal crossing point where yielding is required. Yellow diamond pedestrian signs are warnings about a hazard area rather than a designated crossing.

Question 31Regulatory Signs

A white sign mounted in a median reads KEEP LEFT with an arrow pointing left. What does it require?

  1. Turn left at the next intersection
  2. Stay in the left lane for the next mile
  3. Yield to traffic coming from the left
  4. Pass to the left side of the median or obstacle Correct answer.

Explanation

KEEP LEFT signs direct traffic to pass on the left side of a median, island, or obstruction. They are placement instructions, not turn or lane-assignment commands.

Question 32Regulatory Signs

A white sign shows a red circle and slash over a symbol of a truck. What is the most likely meaning?

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

Explanation

The red circle with a slash is the prohibition symbol, so a slashed truck means trucks may not proceed on that route. Supplemental plates often state weight or time exceptions beneath the symbol.

Question 33Regulatory Signs

A white sign reads NO PARKING 8 AM TO 6 PM with a left-pointing arrow. What does the arrow add?

  1. The sign applies only to vehicles entering from the left
  2. Drivers must park facing left
  3. Parking is allowed on the left at all times
  4. The restriction applies to the curb to the left of the sign Correct answer.

Explanation

On parking signs, an arrow indicates the direction along the curb where the stated rule applies. A left arrow means the no-parking zone extends to the left of the sign.

Question 34Regulatory Signs

A white sign reads TWO-WAY TRAFFIC AHEAD. What should a driver expect?

  1. Oncoming vehicles will share the roadway ahead Correct answer.
  2. The road will become a divided highway
  3. Traffic will merge from the right only
  4. The road will narrow to a single lane

Explanation

This regulatory sign alerts drivers that the road ahead carries traffic in both directions, often after a one-way section. Drivers should keep right and watch for oncoming vehicles.

Question 35Regulatory Signs

A driver on a one-way street sees a white sign reading ONE WAY with an arrow pointing toward the driver. What does this arrangement mean?

  1. The driver may proceed because the arrow points at them
  2. The arrow marks a lane reserved for buses
  3. The driver is facing against the intended flow of traffic Correct answer.
  4. The street becomes two-way after the sign

Explanation

ONE WAY arrows point in the direction traffic is allowed to travel. Seeing the arrow head-on means the driver is oriented opposite to the legal flow and is likely in a wrong-way situation.

Question 36Regulatory Signs

A white sign reads NO RIGHT TURN with a symbol of a right arrow crossed by a red slash. When does this restriction apply?

  1. At all times unless a supplemental plate states otherwise Correct answer.
  2. Only when a red light is showing
  3. Only during the morning rush hour
  4. Only for commercial vehicles

Explanation

Regulatory turn prohibitions apply continuously unless a separate plate lists days or hours. Drivers should scan for such a plate before assuming the ban is time-limited.

Question 37Regulatory Signs

A white sign reads MUST TURN RIGHT with a right-curving arrow. A driver who intended to continue straight should do what?

  1. Back up to the previous intersection
  2. Continue straight because the sign is advisory
  3. Stop and wait for a gap to go straight
  4. Follow the mandatory turn and find a legal route afterward Correct answer.

Explanation

A MUST TURN sign makes the indicated movement mandatory for that lane or position. A driver whose plan conflicts must complete the required turn and reroute legally rather than disregard the sign.

Question 38Regulatory Signs

A white sign reads LANE ENDS MERGE LEFT. What is the safest response?

  1. Move left immediately without checking mirrors
  2. Adjust speed and merge left when a safe gap appears Correct answer.
  3. Accelerate to pass vehicles on the right shoulder
  4. Brake hard and stop in the ending lane

Explanation

The sign warns that the lane is ending, so the driver should plan an early, smooth merge into the continuing lane. Merging requires checking mirrors and blind spots and matching the speed of traffic.

Question 39Regulatory Signs

A white sign reads DO NOT BLOCK INTERSECTION. What behavior does it require?

  1. Wait behind the crosswalk until there is room to clear the intersection Correct answer.
  2. Enter the intersection and stop in the middle if the light turns red
  3. Proceed only when the vehicle ahead has fully cleared the block
  4. Block cross traffic to secure your turn

Explanation

The sign reminds drivers not to enter an intersection unless they can clear it before the signal changes. Waiting behind the crosswalk keeps cross traffic and crosswalks open.

Question 40Regulatory Signs

A white sign reads RIGHT LANE FOR LOCAL TRAFFIC ONLY. A through driver in that lane should do what?

  1. Use the lane only during peak hours
  2. Stay in the lane and continue through the corridor
  3. Change to a through lane before the restriction applies Correct answer.
  4. Stop in the lane and wait for permission

Explanation

A LOCAL TRAFFIC ONLY designation reserves the lane for vehicles accessing nearby properties. Through drivers should move to a lane designated for continuing traffic before the restriction takes effect.

Question 41Regulatory Signs

A white sign reads NO TRUCKS OVER 4 TONS. What determines whether a vehicle is affected?

  1. The state where the vehicle is registered
  2. The number of axles on the vehicle
  3. The length of the vehicle
  4. The vehicle's registered or actual weight compared with the posted limit Correct answer.

Explanation

Weight restriction signs apply based on the vehicle's weight relative to the stated limit. Drivers of vehicles near the threshold should know their loaded weight to comply.

Question 42Regulatory Signs

A white sign reads NO PARKING ANY TIME with a right-pointing arrow. What does the arrow indicate?

  1. Drivers must turn right to find parking
  2. The sign applies to the right lane only
  3. Parking is permitted to the right after 6 PM
  4. The restriction applies along the curb to the right of the sign Correct answer.

Explanation

Arrows on parking signs show the direction along the curb where the rule applies. A right arrow means the no-parking zone runs to the right of the sign.

Question 43Regulatory Signs

A white sign reads YIELD with a red triangle symbol. When must the driver yield?

  1. Never, because the driver has the right of way
  2. When approaching traffic on the intersecting road has the right of way Correct answer.
  3. Only when a pedestrian is present
  4. Only when the light is flashing yellow

Explanation

A YIELD sign requires the driver to slow or stop as needed and let conflicting traffic proceed first. The driver may continue once a safe gap exists.

Question 44Regulatory Signs

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

  1. Driving in the left lane at any time
  2. Overtaking another vehicle in that zone Correct answer.
  3. Changing lanes within an intersection
  4. Passing a stopped school bus

Explanation

A DO NOT PASS sign establishes a no-passing zone where overtaking slower vehicles is prohibited. It is often paired with pavement markings and ends where a PASS WITH CARE sign appears.

Question 45Regulatory Signs

A white sign reads NO LEFT TURN ON RED. What must a driver do when the light is red and they want to turn left?

  1. Sound the horn and proceed
  2. Wait for a green signal before turning Correct answer.
  3. Turn left only if no police officer is present
  4. Turn left after yielding to cross traffic

Explanation

The sign removes any allowance to turn left during a red light, so the driver must wait for a green indication. Yielding does not override an explicit prohibition.

Question 46Regulatory Signs

A white sign reads NO STANDING with a symbol of a parked car. What does it prohibit?

  1. Stopping a vehicle to wait, even briefly, along that curb Correct answer.
  2. Parking overnight only
  3. Loading freight into a business
  4. Driving in the curb lane

Explanation

NO STANDING prohibits a vehicle from waiting at the curb, which is stricter than a no-parking rule that still allows brief stops to load passengers. Drivers may not idle there even momentarily.

Question 47Regulatory Signs

A white sign reads SPEED LIMIT 45 with a plate below reading WHEN FLASHING. What does the plate mean?

  1. The limit applies at all hours regardless of the beacon
  2. The limit drops to 45 mph only at night
  3. The 45 mph limit applies only while the beacon is flashing Correct answer.
  4. The limit is advisory rather than enforceable

Explanation

A WHEN FLASHING plate ties the posted rule to the beacon's operation, so the lower limit is enforceable only while the light flashes. At other times the general limit for the road applies.

Question 48Regulatory Signs

A white sign reads BUSES ONLY beneath a lane symbol. A solo driver in a car wants to use that lane during rush hour. What is correct?

  1. The car may use the lane if traffic is heavy
  2. The car may not use the lane during the posted restriction Correct answer.
  3. The car may use the lane if no bus is visible
  4. The car may use the lane to make a right turn at any point

Explanation

A BUSES ONLY designation restricts the lane to buses during the stated hours, regardless of whether a bus is present. Other vehicles must stay out unless a sign or marking expressly permits a turn movement.

Question 49Regulatory Signs

A white sign reads NO HORN with a horn symbol crossed by a red slash. Where is such a sign commonly posted?

  1. Inside tunnels with heavy traffic
  2. At weigh stations on interstates
  3. Near hospitals, schools, or quiet zones Correct answer.
  4. At rural highway on-ramps

Explanation

No-horn signs are placed where noise would disturb patients, students, or residents, such as near hospitals and schools. Drivers should use the horn only to avoid an immediate hazard in those zones.

Question 50Regulatory Signs

A white sign reads LEFT TURN SIGNAL with an arrow. What does it require of a driver in that lane?

  1. Turn left after yielding to oncoming traffic
  2. Continue straight if the arrow is red
  3. Turn left only during green ball indications
  4. Signal before turning and turn only when the arrow permits Correct answer.

Explanation

A left turn signal sign marks a lane controlled by a dedicated arrow, so the driver must signal and wait for the arrow before turning. A red arrow prohibits the turn even if the through light is green.
