Question 1Regulatory Signs (speed limits, stop, yield, prohibitions, mandatory directions)

On a Colorado road, a red octagonal sign with the word STOP requires a driver to come to a complete stop at which point?

  1. At the center of the intersection to check for cross traffic
  2. At the marked stop line, crosswalk edge, or before entering the intersection if no line exists Correct answer.
  3. Only after the front bumper crosses the crosswalk
  4. Anywhere within 50 feet before the sign

Explanation

Colorado law requires a full stop at the clearly marked stop line. If there is no line, the driver stops at the edge of the crosswalk or the near edge of the intersection before proceeding. Rolling stops are not permitted.

Question 2Regulatory Signs (speed limits, stop, yield, prohibitions, mandatory directions)

A triangular sign with a red border and white center, point directed downward, is placed at an intersection. What action does it require?

  1. Slow down and give the right-of-way to cross traffic Correct answer.
  2. Maintain speed because opposing traffic must yield
  3. Yield only to vehicles approaching from the left
  4. Come to a complete stop before proceeding

Explanation

The downward-pointing triangle is the YIELD sign. A driver must slow down and be prepared to stop, giving the right-of-way to traffic on the intersecting road and to pedestrians. A full stop is only required when traffic conditions demand it.

Question 3Regulatory Signs (speed limits, stop, yield, prohibitions, mandatory directions)

A rectangular white sign with black lettering reads SPEED LIMIT 65. In Colorado, this sign indicates which of the following?

  1. The speed that applies only to trucks and buses
  2. A minimum speed that all vehicles must maintain
  3. The maximum lawful speed in those conditions Correct answer.
  4. A suggested speed for ideal conditions only

Explanation

A posted SPEED LIMIT is the maximum lawful speed under favorable conditions. Colorado's basic speed law still requires drivers to slow below the limit when weather, traffic, or road conditions make the posted speed unsafe.

Question 4Regulatory Signs (speed limits, stop, yield, prohibitions, mandatory directions)

A white rectangular sign displays a black left-turn arrow crossed by a red circle with a diagonal slash. What does this sign mean?

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

Explanation

A red circle with a diagonal slash over a maneuver symbol is the standard prohibition marking. Combined with a left-turn arrow, it means left turns are not allowed at that location. Drivers must proceed to an authorized location to turn.

Question 5Regulatory Signs (speed limits, stop, yield, prohibitions, mandatory directions)

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

  1. Traffic must merge right at the next opportunity
  2. Right turns are prohibited from this lane
  3. Traffic in this lane may turn right or continue straight
  4. Traffic in this lane must turn right Correct answer.

Explanation

An arrow combined with ONLY is a mandatory direction sign. It tells drivers in that lane that the only permitted movement is the one shown by the arrow. Drivers who intend to go straight must use a different lane.

Question 6Regulatory Signs (speed limits, stop, yield, prohibitions, mandatory directions)

A square white sign with a black symbol of a pedestrian crossed by a red slash appears near a mid-block crossing. What is the regulatory meaning?

  1. Pedestrians must yield to vehicles at this crossing
  2. Pedestrians are prohibited from crossing at this location Correct answer.
  3. Pedestrians should cross only during daylight hours
  4. A pedestrian crossing guard is stationed here

Explanation

A red circle or slash through a symbol marks a prohibition. With a pedestrian symbol, the sign means pedestrians may not cross at that spot, typically because no crosswalk or safe sight distance exists. Drivers should still watch for people who cross anyway.

Question 7Regulatory Signs (speed limits, stop, yield, prohibitions, mandatory directions)

A white sign reads DO NOT PASS with a black symbol of two cars. Where is this sign typically placed and what does it require?

  1. At intersections where drivers must not pass a stopped school bus
  2. On freeways where drivers must not use the left lane
  3. At passing zones where drivers may pass only slow vehicles
  4. On segments where passing other traffic is prohibited Correct answer.

Explanation

The DO NOT PASS regulatory sign marks a no-passing zone, often paired with solid yellow pavement lines. Passing another vehicle there is a violation regardless of how slow the leading vehicle is traveling.

Question 8Regulatory Signs (speed limits, stop, yield, prohibitions, mandatory directions)

A red-and-white sign reads WRONG WAY. A driver who sees this sign facing them has most likely done what?

  1. Driven onto a shoulder designated for emergencies
  2. Missed a mandatory turn indicated by a lane sign
  3. Entered a one-way road traveling against the intended direction Correct answer.
  4. Approached a work zone with altered traffic patterns

Explanation

WRONG WAY signs are mounted facing traffic that is traveling opposite the legal direction, commonly at freeway ramps. Seeing one means the driver has entered a one-way facility against traffic and should stop and turn around as soon as it is safe.

Question 9Regulatory Signs (speed limits, stop, yield, prohibitions, mandatory directions)

A driver approaches a STOP sign at a four-way intersection at the same moment as a vehicle on the right. Both arrive at essentially the same time. Who should proceed first?

  1. Whichever vehicle is larger
  2. The vehicle on the right Correct answer.
  3. The vehicle on the left
  4. The driver who is traveling straight rather than turning

Explanation

At a multi-way stop where vehicles arrive at the same time, the vehicle on the right has the right-of-way. Colorado applies this rule at intersections controlled by stop signs on all approaches. If arrival times differ, the first vehicle to stop proceeds first.

Question 10Regulatory Signs (speed limits, stop, yield, prohibitions, mandatory directions)

A driver on a two-lane road sees a SPEED LIMIT 55 sign, but freezing rain has coated the pavement with ice. What is the correct legal speed?

  1. A speed slower than 55 mph that is reasonable for the icy conditions Correct answer.
  2. 55 mph, because the posted limit always governs
  3. 45 mph, because Colorado reduces limits by 10 mph in storms
  4. The speed of the vehicle ahead, to maintain a safe following distance

Explanation

Colorado's basic speed law requires drivers to travel at a speed reasonable for existing conditions, even below the posted maximum. On ice, the lawful speed may be far under 55 mph. Exceeding a safe speed for conditions can be a violation regardless of the posted number.

Question 11Regulatory Signs (speed limits, stop, yield, prohibitions, mandatory directions)

A driver wants to turn left at an intersection where a sign shows a left arrow crossed by a red slash, but a green left-turn arrow is lit on the signal. What should the driver do?

  1. Turn left only after yielding to opposing traffic
  2. Turn left, because the green arrow authorizes the movement Correct answer.
  3. Wait for a sign change before turning
  4. Proceed straight and make a U-turn later

Explanation

A green arrow signal grants a protected right-of-way for that movement and overrides a static prohibition sign posted for other times or movements. When the arrow is displayed, the left turn is authorized. Drivers should still confirm the arrow applies to their lane.

Question 12Regulatory Signs (speed limits, stop, yield, prohibitions, mandatory directions)

A driver in a lane marked with a left-turn arrow and ONLY reaches the intersection but wants to continue straight. What is the proper action?

  1. Change lanes inside the intersection to go straight
  2. Continue straight from the turn lane if no traffic is present
  3. Turn left as the lane requires, then reroute Correct answer.
  4. Stop in the lane and wait for a gap to merge

Explanation

A mandatory direction sign makes the indicated movement the only lawful one from that lane. The driver must complete the left turn and find a legal route afterward. Changing lanes within the intersection or going straight from a turn-only lane is unsafe and unlawful.

Question 13Regulatory Signs (speed limits, stop, yield, prohibitions, mandatory directions)

A yellow sign shows a speed such as 35 mph beneath a curve warning arrow. How does this advisory speed differ from a white SPEED LIMIT sign?

  1. The yellow advisory speed is a recommended safe speed for the curve Correct answer.
  2. The yellow advisory speed replaces the posted limit for that segment
  3. The yellow advisory speed applies only to trucks
  4. The yellow advisory speed is enforceable as a maximum limit

Explanation

Yellow warning signs with advisory speeds recommend a safe speed for a specific hazard such as a curve or ramp. They are not the same as the white regulatory speed limit. However, a driver traveling faster than is safe for the curve can still be cited under the basic speed law.

Question 14Regulatory Signs (speed limits, stop, yield, prohibitions, mandatory directions)

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

  1. Stop, then turn right after yielding if the cross street is clear
  2. Turn right after stopping for at least ten seconds
  3. Wait for the light to turn green before turning right Correct answer.
  4. Turn right only if a police officer directs it

Explanation

Where right turns on red are prohibited by sign, the driver must remain stopped until the signal shows green for that movement. The usual permission to turn right after a full stop and yield does not apply. Turning on red there is a violation even with no cross traffic.

Question 15Regulatory Signs (speed limits, stop, yield, prohibitions, mandatory directions)

A driver is traveling on a road with a solid yellow line on their side and a DO NOT PASS sign. The vehicle ahead is moving well below the limit. What may the driver legally do?

  1. Remain behind the vehicle and pass only where passing is permitted Correct answer.
  2. Pass by using the shoulder to the right
  3. Pass if the vehicle ahead is going more than 10 mph under the limit
  4. Pass only if the maneuver can be completed before the solid line ends

Explanation

A no-passing zone prohibits passing regardless of the leading vehicle's speed. The driver must wait for a segment where passing is lawfully allowed, such as a marked passing zone with broken lines. Passing on the shoulder is also illegal.

Question 16Regulatory Signs (speed limits, stop, yield, prohibitions, mandatory directions)

A white sign with a red circle and slash shows a symbol of a bicycle. What does this sign communicate to bicyclists and drivers?

  1. Bicycles must use the adjacent sidewalk
  2. Bicycles are prohibited from this facility Correct answer.
  3. Bicycles have the right-of-way over motor vehicles here
  4. A bicycle lane begins at this point

Explanation

A red circle with a slash over a bicycle symbol prohibits bicycles from the roadway or facility where it is posted, such as certain freeways or tunnels. It does not grant or remove right-of-way at crossings. Bicyclists must use an alternate legal route.

Question 17Regulatory Signs (speed limits, stop, yield, prohibitions, mandatory directions)

At a yield sign, a driver slows but sees an approaching vehicle close enough to conflict. What is the correct action?

  1. Continue at the same speed because the other driver must yield
  2. Stop and wait until it is safe to proceed Correct answer.
  3. Sound the horn and proceed
  4. Accelerate to enter the intersection ahead of the other vehicle

Explanation

A yield sign obligates the driver to give way to conflicting traffic. If an approaching vehicle would be forced to slow or swerve, the yielding driver must stop and wait for a safe gap. Proceeding and expecting the other driver to yield is a common cause of collisions.

Question 18Regulatory Signs (speed limits, stop, yield, prohibitions, mandatory directions)

A sign at a freeway on-ramp reads DO NOT ENTER. A driver mistakenly heading toward it should take which action?

  1. Flash headlights and continue to warn oncoming drivers
  2. Continue because on-ramps allow two-way traffic
  3. Proceed to the shoulder and merge with traffic
  4. Stop immediately and back out or turn around when safe Correct answer.

Explanation

DO NOT ENTER marks the exit end of a one-way facility, and driving past it puts the vehicle head-on into traffic. The driver should stop at once and leave the ramp safely, such as by backing out or turning around where conditions permit. Continuing is extremely dangerous.

Question 19Regulatory Signs (speed limits, stop, yield, prohibitions, mandatory directions)

A driver sees a sign reading NO U-TURN at a median opening. The driver has already passed the point of no return and cannot safely complete a U-turn. What is the best course?

  1. Complete the U-turn anyway to correct the error
  2. Stop in the median and wait for a gap
  3. Make a three-point turn across the median
  4. Continue to the next legal location to reverse direction Correct answer.

Explanation

A NO U-TURN sign prohibits the maneuver at that opening, and an error in route planning does not create an exception. The driver should continue and use the next intersection or interchange where a legal turnaround is available. Stopping in a median or crossing it is unsafe.

Question 20Regulatory Signs (speed limits, stop, yield, prohibitions, mandatory directions)

A driver passes a sign reading SPEED LIMIT 75 on a rural interstate, then enters a construction zone where orange signs post 55. Which limit applies?

  1. 55 mph, because the posted work-zone limit governs Correct answer.
  2. The speed of the pilot car, if one is present
  3. 75 mph, because the white sign is the regulatory limit
  4. 65 mph, the default for construction zones

Explanation

Posted work-zone speed limits are regulatory and supersede the normal highway limit for that segment. Colorado also imposes enhanced penalties for speeding in some construction zones when workers are present. Drivers must obey the lower posted figure.

Question 21Regulatory Signs (speed limits, stop, yield, prohibitions, mandatory directions)

A white sign shows a black arrow curving left with the word ONLY. A driver in that lane intends to turn right at the intersection. What must the driver do?

  1. Turn right from the lane if no left-turning traffic is present
  2. Straddle both lanes to choose a direction at the intersection
  3. Wait in the lane for the signal to change, then turn right
  4. Follow the mandatory left movement and reroute afterward Correct answer.

Explanation

A mandatory direction sign with ONLY requires the indicated movement from that lane. The driver must make the left turn and then find a legal route to the intended destination. Turning against the arrow or straddling lanes is unsafe and unlawful.

Question 22Regulatory Signs (speed limits, stop, yield, prohibitions, mandatory directions)

A driver at a stop sign intends to turn right but sees a pedestrian entering the crosswalk from the right. Who has the right-of-way, and what must the driver do?

  1. The pedestrian, so the driver must wait until the crosswalk clears Correct answer.
  2. The driver, because the pedestrian entered after the vehicle stopped
  3. Whichever party arrived at the crossing first
  4. The driver, if the turn signal was activated before the pedestrian stepped off the curb

Explanation

Pedestrians in a crosswalk have the right-of-way, and a driver turning at a stop sign must yield to them. The driver must remain stopped until the pedestrian has cleared the path. A turn signal does not transfer right-of-way from a pedestrian.

Question 23Regulatory Signs (speed limits, stop, yield, prohibitions, mandatory directions)

A driver approaches a flashing red signal at an intersection after the power fails. How should the driver treat this signal?

  1. As a yield sign, slowing only if traffic is present
  2. As a stop sign, stopping fully and proceeding when safe Correct answer.
  3. As a warning to reduce speed by 10 mph
  4. As a green light, proceeding without stopping

Explanation

A flashing red signal functions as a stop sign: the driver must come to a complete stop, yield to traffic and pedestrians, and proceed only when safe. A flashing yellow, by contrast, means slow down and proceed with caution. Confusing the two causes intersection collisions.

Question 24Regulatory Signs (speed limits, stop, yield, prohibitions, mandatory directions)

A driver is in a lane controlled by a sign showing a straight arrow with ONLY, but traffic ahead is stopped and the driver wants to turn right to avoid the backup. What is the correct legal analysis?

  1. The driver must remain in the lane and proceed straight when traffic moves Correct answer.
  2. The driver may use the shoulder to reach the right-turn lane
  3. The driver may turn right after signaling and yielding
  4. The driver may turn right because congestion makes the mandatory sign advisory

Explanation

A mandatory direction sign remains binding regardless of congestion; it is regulatory, not advisory. The driver must follow the indicated movement and wait for traffic to move. Using a shoulder or making an unauthorized turn from the lane violates the sign.

Question 25Regulatory Signs (speed limits, stop, yield, prohibitions, mandatory directions)

A driver sees a white rectangular sign reading KEEP RIGHT. A median divider is directly ahead. What does this sign require?

  1. Merge right into the adjacent lane immediately
  2. Pass on the left side of the divider
  3. Keep to the right of the divider or obstacle Correct answer.
  4. Stop before the divider and wait for guidance

Explanation

KEEP RIGHT is a regulatory sign directing traffic to pass to the right of a median, island, or other obstacle. It is common at channelized intersections and divided highways. Passing to the left of the divider would put the vehicle in opposing traffic.

Question 26Regulatory Signs (speed limits, stop, yield, prohibitions, mandatory directions)

A white rectangular sign with black lettering reads SPEED LIMIT 65. What does this sign establish on a Colorado highway?

  1. A recommended speed for poor weather
  2. The maximum lawful speed under normal conditions Correct answer.
  3. The minimum speed for the left lane
  4. An advisory speed for the next curve

Explanation

A white speed limit sign is regulatory and sets the maximum lawful speed when conditions are normal. Drivers must still slow below that number when weather, traffic, or road surface requires it. The posted value is enforceable, not merely a suggestion.

Question 27Regulatory Signs (speed limits, stop, yield, prohibitions, mandatory directions)

A red octagon with white letters reads STOP. Where must the driver's vehicle come to a complete halt?

  1. At the stop line, or at the edge of the crosswalk or intersection if no line exists Correct answer.
  2. Only when another vehicle is visible in either direction
  3. Fifty feet before the sign in all cases
  4. Anywhere within the intersection before proceeding

Explanation

A STOP sign requires a full stop at the marked stop line. If there is no line, the stop belongs at the crosswalk, and if there is no crosswalk, at the edge of the traveled way before entering. Stopping short of or past that point does not satisfy the requirement.

Question 28Regulatory Signs (speed limits, stop, yield, prohibitions, mandatory directions)

A driver approaches a red-and-white triangle sign reading YIELD at the end of an on-ramp merging onto a highway. What does the sign require?

  1. Accelerate to match traffic and merge without yielding
  2. Slow as needed and let highway traffic have the right of way Correct answer.
  3. Come to a complete stop before merging in every case
  4. Stop only if a vehicle is already in the merge lane beside the sign

Explanation

A YIELD sign means the driver must slow and give the right of way to traffic on the road being entered. A full stop is required only when necessary to avoid conflict. Yielding is an obligation to let others proceed first, not a suggestion.

Question 29Regulatory Signs (speed limits, stop, yield, prohibitions, mandatory directions)

A white sign displays a red circle with a diagonal slash over a black symbol of a left-turn arrow. What does this sign mean?

  1. A left-turn lane begins ahead
  2. Left turns are prohibited at this location Correct answer.
  3. Left turns are permitted only for buses
  4. Left turns are allowed after a complete stop

Explanation

A red circle with a diagonal slash is the universal prohibition symbol, so the crossed-out arrow means the maneuver is not allowed. The sign is regulatory and enforceable. Drivers needing to go that direction must find another route or turn point.

Question 30Regulatory Signs (speed limits, stop, yield, prohibitions, mandatory directions)

A white rectangular sign reads ONE WAY with a black arrow pointing right. What does this sign tell a driver?

  1. Traffic on that roadway moves only in the direction of the arrow Correct answer.
  2. Parking is allowed only on the right side
  3. The right lane ends and traffic must merge left
  4. A right turn is prohibited at the next intersection

Explanation

The ONE WAY sign with an arrow indicates that all traffic on that street or lane flows in the arrow's direction. Entering against the arrow would put the driver in the wrong direction. Drivers should check the arrow before turning onto the roadway.

Question 31Regulatory Signs (speed limits, stop, yield, prohibitions, mandatory directions)

A white sign with black lettering reads KEEP RIGHT with an arrow. A raised median is directly ahead of the driver. What action does the sign require?

  1. Pass to the left side of the median
  2. Pass to the right side of the median or obstacle Correct answer.
  3. Stop and wait for a gap in oncoming traffic
  4. Reduce speed and continue straight over the median

Explanation

KEEP RIGHT is a regulatory sign directing traffic to pass on the right side of a median, island, or other obstruction. It keeps opposing flows separated and prevents head-on conflicts. Drivers should position right before reaching the divider.

Question 32Regulatory Signs (speed limits, stop, yield, prohibitions, mandatory directions)

A white sign reads DO NOT ENTER. Under what circumstance may a driver proceed past it?

  1. Only if the driver is turning around within 100 feet
  2. Under no circumstance, because the roadway is closed to that direction of travel Correct answer.
  3. Only during overnight hours when traffic is light
  4. Only if a flagger waves the vehicle through

Explanation

DO NOT ENTER marks a roadway or ramp where traffic travels toward the driver, so entering would mean driving against the flow. There is no time-of-day or convenience exception. A driver who sees it should turn around or choose another route.

Question 33Regulatory Signs (speed limits, stop, yield, prohibitions, mandatory directions)

A white sign shows a black arrow pointing straight ahead with the word ONLY beneath it. A driver in that lane wants to turn right at the coming intersection. What must the driver do?

  1. Turn right only if no vehicle is in the right lane
  2. Stop in the lane and wait for a gap to change lanes at the intersection
  3. Turn right from that lane after signaling
  4. Continue straight and find a legal route to the destination Correct answer.

Explanation

A lane marked with a straight arrow and ONLY is reserved for through movement, so a turn from it is not permitted. The driver should follow the lane's required movement and reroute afterward. Changing lanes must happen earlier, where markings allow it.

Question 34Regulatory Signs (speed limits, stop, yield, prohibitions, mandatory directions)

A driver is stopped at a red light where a sign reads NO TURN ON RED. The cross street is completely clear. What should the driver do?

  1. Wait for the green light before making the turn Correct answer.
  2. Turn right after sounding the horn
  3. Turn right after stopping, since the way is clear
  4. Turn right only if another vehicle is behind

Explanation

NO TURN ON RED removes the usual permission to turn after stopping at a red signal. A clear cross street does not change the restriction. The driver must wait for a green indication before turning.

Question 35Regulatory Signs (speed limits, stop, yield, prohibitions, mandatory directions)

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

  1. A minimum speed of 55 mph now applies
  2. The driver must immediately accelerate to 55 mph
  3. The posted 55 mph limit no longer applies and the general or default limit resumes Correct answer.
  4. The road ahead is closed to through traffic

Explanation

An END sign terminates a special posted speed zone, so the limit reverts to whatever applies beyond it, such as a default statutory or newly posted limit. Drivers should watch for the next speed sign rather than assume 55 continues. The sign does not command a speed.

Question 36Regulatory Signs (speed limits, stop, yield, prohibitions, mandatory directions)

A driver enters a construction zone where an orange sign reads SPEED LIMIT 45 ENFORCED BY AIRCRAFT AND PATROL. The permanent limit nearby is 65. Which limit governs?

  1. 45 mph, because the posted work-zone limit controls in the zone Correct answer.
  2. 45 mph only at night when workers are absent
  3. 65 mph, because orange signs are only advisory
  4. 65 mph unless workers are visibly present

Explanation

A posted speed limit in a work zone is regulatory and replaces the normal limit for that stretch. Posted work-zone limits are commonly enforced with doubled fines when workers are present. The driver must obey the lower number regardless of the prior limit.

Question 37Regulatory Signs (speed limits, stop, yield, prohibitions, mandatory directions)

A white sign at a median opening shows a U-shaped arrow crossed by a red slash. A driver who has already entered the opening and cannot safely reverse should do what?

  1. Stop in the median and wait for a police officer
  2. Back up into the traffic lane to undo the maneuver
  3. Continue driving the wrong way to the next exit
  4. Complete the turn only if it can be done safely, then re-route legally Correct answer.

Explanation

The sign prohibits U-turns at that opening, but once a driver is committed, the priority is to finish safely rather than reverse into traffic. The driver should then find a lawful place to turn around. Backing up or driving wrong-way multiplies the hazard.

Question 38Regulatory Signs (speed limits, stop, yield, prohibitions, mandatory directions)

A driver on a two-lane mountain road sees a DO NOT PASS sign with a solid yellow line on their side. The vehicle ahead is slow but the oncoming lane is clear for a long distance. What does the sign require?

  1. Pass as soon as the oncoming lane is clear
  2. Pass only if the vehicle ahead signals a turn
  3. Remain behind the vehicle and do not cross into the oncoming lane to pass Correct answer.
  4. Pass if the driver exceeds the speed limit briefly

Explanation

DO NOT PASS combined with a solid yellow line on the driver's side prohibits crossing into the opposing lane to overtake. Clear sight distance does not override a posted no-passing zone. The driver must wait until the restriction ends.

Question 39Regulatory Signs (speed limits, stop, yield, prohibitions, mandatory directions)

A white sign shows a bicycle symbol inside a red circle with a slash, mounted beside a roadway. What does this sign communicate?

  1. A bike lane begins at that point
  2. Bicyclists are prohibited from that roadway or path Correct answer.
  3. Bicyclists have the right of way over motor vehicles
  4. Bicyclists must walk their bikes through the area

Explanation

The red circle and slash mark a prohibition, so the bicycle symbol means cyclists may not use that facility. Such signs appear where cycling would be unsafe, such as certain tunnels or expressway segments. The sign does not create a right-of-way rule.

Question 40Regulatory Signs (speed limits, stop, yield, prohibitions, mandatory directions)

A driver is in a lane posted with a sign showing a left-turn arrow and ONLY, but wants to go straight. Traffic is heavy and the driver is already at the stop line. What is the safest lawful action?

  1. Proceed straight from the turn lane since the light is green
  2. Change lanes inside the intersection to continue straight
  3. Wait at the line until the lane can be changed
  4. Make the required left turn and then find a route to the intended destination Correct answer.

Explanation

A mandatory left-turn lane requires the driver to turn left; the lane designation is enforceable. Once at the line, the safe option is to turn and reroute rather than violate the lane use. Late lane changes within the intersection are unsafe and unlawful.

Question 41Regulatory Signs (speed limits, stop, yield, prohibitions, mandatory directions)

A driver approaches a STOP sign and a pedestrian steps into the crosswalk from the left. The driver intends to turn right. Who has the right of way?

  1. The vehicle, because it has already stopped at the sign
  2. The vehicle, because it is turning right rather than going straight
  3. The pedestrian, who must be allowed to cross before the vehicle proceeds Correct answer.
  4. Whichever party arrived at the location first

Explanation

Pedestrians in a marked or unmarked crosswalk have the right of way over a vehicle at a stop sign. The driver must remain stopped until the pedestrian has cleared the vehicle's path. Stopping at the sign does not transfer right of way to the driver.

Question 42Regulatory Signs (speed limits, stop, yield, prohibitions, mandatory directions)

A driver sees a white sign reading STOP HERE ON RED mounted at an intersection with a loop detector. What does the sign require?

  1. Stop at the marked point when the signal is red so the detector registers the vehicle Correct answer.
  2. Stop at the sign before turning right on red
  3. Stop only when a pedestrian is present
  4. Stop at the sign regardless of the signal color

Explanation

STOP HERE ON RED directs drivers to halt at a specific painted point so the vehicle is detected and the signal can serve the approach. Stopping short of the mark may leave the vehicle undetected. The instruction applies when the signal is red.

Question 43Regulatory Signs (speed limits, stop, yield, prohibitions, mandatory directions)

A driver sees a white sign reading SPEED LIMIT 40 on a city street but heavy fog cuts visibility to about 100 feet. What is the correct action?

  1. Drive above 40 mph to clear the foggy area faster
  2. Maintain exactly 40 mph because that is the posted limit
  3. Drive below 40 mph as conditions require while staying within the posted maximum Correct answer.
  4. Stop in the lane and wait for the fog to lift

Explanation

A posted speed limit is a maximum for normal conditions, and the basic speed law requires driving slower when visibility or road surface demands it. Fog that shortens sight distance calls for reduced speed. The posted number does not compel driving at that speed.

Question 44Regulatory Signs (speed limits, stop, yield, prohibitions, mandatory directions)

A white sign at an intersection displays a black arrow curving right with a red slash through it. A driver planning a right turn arrives at the intersection. What does the sign mean?

  1. Right turns are allowed only after a full stop
  2. A right-turn lane opens just past the intersection
  3. Right turns are prohibited at this intersection Correct answer.
  4. Right turns are permitted only for local traffic

Explanation

A slashed arrow indicates that the maneuver shown is not allowed, so a crossed-out right-curving arrow prohibits right turns. The restriction may exist because of one-way flow, sight distance, or pedestrian patterns. Drivers must choose a different route.

Question 45Regulatory Signs (speed limits, stop, yield, prohibitions, mandatory directions)

A driver sees a white sign reading NO PARKING ANY TIME along a curb. The driver needs to leave the car briefly to use a nearby mailbox. What does the sign allow?

  1. Parking if the hazard lights are on
  2. No stopping or standing at the curb at any time, so the driver must park elsewhere Correct answer.
  3. A brief stop of under five minutes for errands
  4. Parking only during daylight hours

Explanation

NO PARKING ANY TIME prohibits leaving a vehicle at the curb at all hours, and such zones are typically kept clear for traffic flow or emergencies. Hazard lights or a short errand do not create an exception. The driver must find a lawful space.

Question 46Regulatory Signs (speed limits, stop, yield, prohibitions, mandatory directions)

A driver on a freeway sees a white sign with a red circle and slash over a symbol of a truck. What does this sign indicate for trucks?

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

Explanation

The red circle and slash mark a prohibition, so a crossed-out truck symbol bars trucks from the route or lane shown. Such restrictions often protect steep grades, tunnels, or residential segments. The sign does not impose a speed or time condition.

Question 47Regulatory Signs (speed limits, stop, yield, prohibitions, mandatory directions)

A driver sees a white sign reading LEFT LANE MUST TURN LEFT mounted over the leftmost lane of a multi-lane road. The driver is in that lane and wants to continue straight. What is required?

  1. Stop in the lane until the arrow changes
  2. Continue straight because the sign is only a suggestion
  3. Merge right at the intersection if space allows
  4. Turn left as the lane designation requires and reroute afterward Correct answer.

Explanation

A MUST TURN sign is regulatory and assigns a mandatory movement to the lane beneath it. Drivers in that lane must follow the designated turn. Continuing straight or making a late merge would violate the lane assignment.

Question 48Regulatory Signs (speed limits, stop, yield, prohibitions, mandatory directions)

A driver approaches a sign reading WEIGHT LIMIT 10 TONS on a bridge. The driver's loaded truck weighs 12 tons. What is the correct action?

  1. Cross only if no other vehicles are on the bridge
  2. Cross slowly to reduce stress on the bridge
  3. Take an alternate route, because the vehicle exceeds the posted structural limit Correct answer.
  4. Cross because the limit applies only to commercial vehicles

Explanation

A weight limit sign is a regulatory restriction based on the structure's capacity, so a vehicle above the limit may not cross. Slowing down does not reduce the load the bridge must carry. The driver must use a route that can handle the weight.

Question 49Regulatory Signs (speed limits, stop, yield, prohibitions, mandatory directions)

A driver sees a white sign reading SPEED LIMIT 25 with a smaller sign below reading WHEN CHILDREN ARE PRESENT. It is 8 p.m. and the school playground is empty. How should the driver interpret the limit?

  1. The sign is advisory and cannot be enforced
  2. The 25 mph limit applies at all hours regardless of the condition
  3. The 25 mph limit applies only when children are actually present, so the normal limit governs now Correct answer.
  4. The 25 mph limit applies only during school hours on weekdays

Explanation

A conditional plaque such as WHEN CHILDREN ARE PRESENT ties the lower limit to that condition. When no children are present, the otherwise applicable limit governs. Drivers should still scan for children who might appear unexpectedly.

Question 50Regulatory Signs (speed limits, stop, yield, prohibitions, mandatory directions)

A driver sees a white sign reading NO LEFT TURN between 4 PM and 6 PM. It is 5:30 PM and the driver wants to turn left into a driveway just past the intersection. What does the sign allow?

  1. A left turn if the driver is entering a private driveway rather than a street
  2. A left turn if the driver signals well in advance
  3. A left turn because the restriction covers only commercial vehicles
  4. No left turn at the intersection during that window, so the driver must approach the driveway another way Correct answer.

Explanation

A time-qualified turn prohibition bars the left turn at the signed location during the stated hours, regardless of the destination beyond the intersection. During peak hours such restrictions protect traffic flow. The driver should reroute to reach the driveway legally.
