Question 1Road Signs

A driver approaches an intersection where a red octagonal sign with white lettering faces them. What must the driver do?

  1. Come to a complete stop before the crosswalk or stop line Correct answer.
  2. Yield only to vehicles already inside the intersection
  3. Stop only when pedestrians are present
  4. Slow down and proceed if no traffic is visible

Explanation

The octagonal red sign reading STOP is the only sign with this shape, and its shape alone requires a full stop. The stop must be made before the stop line, crosswalk, or entering the intersection, and the driver then yields to any conflicting traffic or pedestrians. A rolling slowdown does not satisfy the legal requirement.

Question 2Road Signs

What does a downward-pointing triangle sign with a red border and white center indicate?

  1. The roadway ends ahead
  2. A stop is required in all circumstances
  3. Traffic must merge from the right
  4. The driver must yield the right-of-way ahead Correct answer.

Explanation

The inverted triangle with a red border is the YIELD sign, and its unique shape is recognizable even when the face is obscured. It directs the driver to slow and give the right-of-way to traffic on the intersecting road. A full stop is only required when yielding cannot otherwise be accomplished safely.

Question 3Road Signs

A yellow diamond-shaped sign is used on Iowa roadways to convey what type of information?

  1. Warning of an upcoming hazard or change in conditions Correct answer.
  2. Regulatory requirements enforceable by law
  3. Construction zone speed limits
  4. Services available at the next exit

Explanation

Yellow diamonds are warning signs that alert drivers to conditions ahead such as curves, intersections, or narrowing lanes. They do not themselves impose a legal requirement; instead they prepare the driver to adjust speed or position. Regulatory signs, by contrast, are typically white rectangles or red-and-white combinations.

Question 4Road Signs

An orange diamond-shaped sign appears along the shoulder of a highway. What should the driver expect?

  1. The pavement is permanently uneven
  2. A school crossing zone is active
  3. A rest area is approaching
  4. A work zone or temporary traffic condition is ahead Correct answer.

Explanation

Orange is the color reserved for construction and maintenance zones, and orange diamonds warn of temporary conditions such as workers, lane shifts, or equipment. Drivers should reduce speed and increase following distance in these areas. Permanent hazards use yellow, not orange.

Question 5Road Signs

A circular sign with a black diagonal slash through a symbol indicates what?

  1. A warning about the symbol shown ahead
  2. A service related to the symbol is nearby
  3. The action shown is recommended
  4. The action or vehicle shown is prohibited Correct answer.

Explanation

A circle with a diagonal slash is the universal prohibition symbol, so the pictured action or vehicle is not permitted. Common examples include no U-turn, no left turn, and no bicycles. The slash is the key element that turns the symbol into a restriction.

Question 6Road Signs

What is the standard meaning of a white rectangular sign with black lettering such as "SPEED LIMIT 55"?

  1. A warning that the road curves ahead
  2. A suggested speed for ideal conditions
  3. The maximum lawful speed under normal conditions Correct answer.
  4. The minimum speed permitted on the roadway

Explanation

White rectangular signs with black text are regulatory signs, and a speed limit sign sets the maximum lawful speed in normal conditions. Drivers may still need to travel slower in rain, snow, or darkness. The posted number is not a target or a suggestion.

Question 7Road Signs

A five-sided sign shaped like a house, with a yellow-green background, marks what location?

  1. A school zone or school crossing Correct answer.
  2. A hospital entrance
  3. A railroad crossing
  4. A pedestrian mall

Explanation

The pentagon shape is reserved for school signs, and the fluorescent yellow-green color increases visibility near schools. Drivers should watch for children and obey any posted reduced speed limit. The pentagon is distinct from the circular railroad advance warning sign.

Question 8Road Signs

A round yellow sign bearing a black X and the letters "RR" warns the driver of what?

  1. A roundabout with right-of-way rules
  2. A reduced-speed rural zone
  3. A railroad crossing ahead Correct answer.
  4. A rest area with RV parking

Explanation

The circular yellow advance warning sign with an X and RR indicates a railroad crossing is ahead. Drivers should slow, look both ways, and be prepared to stop for an approaching train. The round shape is used only for this railroad advance warning.

Question 9Road Signs

A driver sees a yellow diamond sign showing a black arrow curving to the right. How should the driver respond?

  1. Reduce speed before entering the curve and stay in the lane Correct answer.
  2. Stop completely before the curve begins
  3. Move to the left lane to widen the turn
  4. Maintain speed because the sign is only advisory

Explanation

A curve warning sign tells the driver that the roadway bends ahead, and safe handling requires slowing before the curve rather than braking within it. Staying centered in the lane keeps the vehicle from drifting into adjacent traffic. The sign is a warning, but ignoring it invites loss of control.

Question 10Road Signs

A white rectangular sign shows a black arrow bending left with a red circle and slash over it. What does this sign require?

  1. Left turns are prohibited at this location Correct answer.
  2. Left turns are permitted only for buses
  3. The left lane ends ahead
  4. A left curve is approaching

Explanation

The red circle and diagonal slash over the turn arrow form a prohibition sign, meaning a left turn is not allowed. The white rectangular background confirms it is a regulatory restriction enforceable by law. Drivers who need to turn left must find an alternate route.

Question 11Road Signs

A driver encounters a yellow diamond sign reading "LANE ENDS" with an arrow indicating the right lane merges left. What is the safest action?

  1. Signal and merge left when a safe gap is available Correct answer.
  2. Accelerate to pass vehicles before the lane closes
  3. Brake sharply at the merge point and wait
  4. Continue in the right lane until it physically ends, then merge

Explanation

The lane-ends warning tells the driver that the right lane will terminate, so the correct response is to signal and merge into the through lane while a safe gap exists. Early, smooth merging reduces conflict at the taper point. Speeding up to beat other vehicles creates unnecessary risk.

Question 12Road Signs

A driver approaching an intersection sees a yellow diamond sign with a black cross symbol. What does this warning indicate?

  1. A church is nearby
  2. A hospital zone begins
  3. A four-way intersection is ahead Correct answer.
  4. A railroad crossing is ahead

Explanation

The crossroad symbol on a yellow diamond warns of an intersection ahead where traffic may cross the driver's path. Drivers should scan for vehicles and be ready to yield or stop as required. The symbol is distinct from the railroad advance warning, which uses a round sign with RR.

Question 13Road Signs

A driver on a two-lane road sees a yellow diamond sign with a black arrow pointing down and to the left, indicating a divided highway begins. What should the driver expect?

  1. A left turn lane is added
  2. The road will narrow to one lane
  3. Oncoming traffic will be separated by a median Correct answer.
  4. A one-way street begins immediately

Explanation

The divided-highway-begins sign warns that opposing traffic will soon be separated by a median or barrier. Drivers should stay to the right of the divider and not cross it. The sign does not indicate a lane reduction or a turn lane.

Question 14Road Signs

A driver sees a yellow diamond sign showing a pedestrian figure walking within a triangle of lines. What hazard does this warn of?

  1. A school bus stop ahead
  2. A bicycle lane crossing ahead
  3. A hiking trail entrance ahead
  4. A pedestrian crossing or walking area ahead Correct answer.

Explanation

The pedestrian warning sign alerts drivers that people may be crossing or walking along the roadway ahead. Drivers should reduce speed and scan both sides of the road. School bus stops and bicycle crossings use separate symbols.

Question 15Road Signs

A blue rectangular sign with a white "H" symbol appears near an exit. What does this sign indicate?

  1. A historical marker site
  2. A hospital is located at or near this exit Correct answer.
  3. A hazardous cargo route
  4. A highway maintenance station

Explanation

Blue signs provide traveler services, and the white H symbol identifies a hospital accessible from the exit. Drivers with medical emergencies should follow this sign. The symbol is not a hazard warning or a maintenance indicator.

Question 16Road Signs

A brown rectangular sign along a rural Iowa highway shows a symbol for a park. What is the purpose of this sign color?

  1. To mark a school zone
  2. To identify recreation and cultural points of interest Correct answer.
  3. To indicate a mandatory speed reduction
  4. To warn of construction activity

Explanation

Brown signs are reserved for recreation, cultural, and points-of-interest guidance, such as parks and historic sites. They help travelers find attractions without serving as warnings or regulations. Construction uses orange, and school zones use fluorescent yellow-green.

Question 17Road Signs

A driver sees a yellow diamond sign reading "STOP AHEAD" below a smaller placard. What is the appropriate response?

  1. Begin slowing in preparation for the upcoming stop Correct answer.
  2. Stop immediately at the warning sign
  3. Change lanes to avoid the stop
  4. Continue at the current speed until the stop sign is visible

Explanation

The STOP AHEAD warning gives advance notice so drivers can reduce speed before reaching the actual stop sign. It is not itself a stop point, but it signals that a legal stop is coming. Early braking prevents abrupt stops and rear-end collisions.

Question 18Road Signs

A driver approaches a yellow diamond sign showing a traffic signal symbol. What does this sign mean?

  1. A traffic signal is ahead and may require a stop Correct answer.
  2. A stop sign is being replaced by a signal
  3. A flashing yellow light is malfunctioning
  4. A pedestrian signal is out of service

Explanation

The signal-ahead warning alerts drivers that a traffic light controls the upcoming intersection, often where sight distance is limited. Drivers should be prepared to stop if the light is red or turns yellow. The sign does not describe signal malfunctions or replacements.

Question 19Road Signs

A yellow diamond sign depicts a black arrow pointing down a steep slope with a percentage figure. What does the percentage represent?

  1. The speed limit on the descent
  2. The width of the roadway
  3. The grade of the hill ahead Correct answer.
  4. The distance to the bottom of the hill

Explanation

The hill sign with a percentage shows the steepness, or grade, of the descent ahead. A higher percentage means a steeper hill, and drivers should slow down and consider a lower gear. The number is not a speed limit or a distance measurement.

Question 20Road Signs

A driver sees a yellow diamond sign with a symbol of a truck on a downgrade. What is this sign warning of?

  1. A truck parking area
  2. A steep grade where trucks may travel slowly Correct answer.
  3. A truck route detour
  4. A weigh station ahead

Explanation

The truck-on-grade warning alerts drivers that heavy vehicles may be moving slowly on a steep descent ahead. Passenger car drivers should be prepared to encounter slow traffic and avoid cutting in front of trucks that need braking distance. The sign is not a route or facility marker.

Question 21Road Signs

At an intersection, a driver faces a flashing red signal. What is the correct action?

  1. Proceed without stopping if the way appears clear
  2. Wait for the signal to turn green
  3. Treat it as a yield sign and slow only
  4. Stop, yield, and proceed when safe Correct answer.

Explanation

A flashing red signal functions like a stop sign: the driver must come to a full stop, yield to crossing traffic and pedestrians, and proceed only when safe. It does not turn green, so waiting for a green indication is not appropriate. Proceeding without stopping violates the signal.

Question 22Road Signs

A driver approaches an intersection with a flashing yellow signal overhead. What does this signal require?

  1. Stop only if a vehicle is present
  2. Proceed with caution while yielding to traffic and pedestrians Correct answer.
  3. A complete stop before entering
  4. Yield only to vehicles from the right

Explanation

A flashing yellow signal means the driver may proceed but must do so cautiously, scanning for conflicting traffic and pedestrians. It does not require a stop the way a flashing red does. Yielding obligations still apply to any traffic already lawfully in the intersection.

Question 23Road Signs

A driver enters a work zone where an orange sign reads "FLAGGER AHEAD" and a worker is holding a paddle. What should the driver do?

  1. Maintain speed and rely on other drivers to slow
  2. Sound the horn and continue through the zone
  3. Follow the flagger's directions, stopping or proceeding as signaled Correct answer.
  4. Ignore the flagger if the light is green

Explanation

A flagger controls traffic through a work zone, and drivers must obey the flagger's signals, which may include stopping even when no other control is present. Disregarding a flagger is both unsafe and a violation. The flagger's directions take precedence over normal traffic flow assumptions.

Question 24Road Signs

A driver sees a white rectangular sign reading "DO NOT PASS" with a black arrow. What does this regulatory sign mean?

  1. Passing is prohibited in the zone indicated by the sign Correct answer.
  2. A passing lane opens ahead
  3. The lane will end ahead
  4. Passing is allowed only for trucks

Explanation

DO NOT PASS is a regulatory sign that prohibits overtaking other vehicles in the indicated area, often because of limited sight distance. Drivers must remain behind slower vehicles until the restriction ends. The sign does not open a passing lane or apply only to trucks.

Question 25Road Signs

A driver sees a yellow diamond sign with a symbol of a bicycle and a lane arrow. What is the safest interpretation?

  1. Bicycles are prohibited on this road
  2. A bicycle shop is nearby
  3. A bicycle lane or crossing is ahead, so watch for cyclists Correct answer.
  4. Cyclists must yield to all vehicles

Explanation

The bicycle warning sign alerts drivers that cyclists may be present in a lane or crossing ahead. Drivers should reduce speed, scan carefully, and give cyclists room. The sign is a warning, not a prohibition or a service marker.

Question 26Road Signs

An Iowa driver sees an eight-sided red sign at an intersection. What must the driver do when the vehicle reaches the sign?

  1. Yield only to vehicles already in the intersection
  2. Slow to about 15 mph and proceed if the way is clear
  3. Stop only when other traffic is visible
  4. Come to a complete stop before the crosswalk or stop line Correct answer.

Explanation

The octagonal red sign is the universal STOP sign, and Iowa law requires a full stop at the marked stop line, crosswalk, or before entering the intersection. A rolling slow-down does not satisfy the requirement even when the road looks empty. Failing to stop fully is a moving violation.

Question 27Road Signs

A downward-pointing red-and-white triangle at an intersection means the driver should take which action?

  1. Stop completely and then proceed
  2. Accelerate to clear the intersection before conflicting traffic
  3. Sound the horn before entering the intersection
  4. Slow down and give the right-of-way to cross traffic and pedestrians Correct answer.

Explanation

The inverted triangle is the YIELD sign. It requires the driver to slow and, if necessary, stop to let cross traffic and pedestrians go first. It does not demand a mandatory full stop when the way is clearly open.

Question 28Road Signs

A yellow diamond sign on an Iowa highway shows a black symbol of a deer leaping. What should the driver anticipate?

  1. A livestock auction facility ahead
  2. A deer crossing area where animals may enter the roadway Correct answer.
  3. A wildlife refuge where vehicles must stop for animals
  4. A hunting area where firearms discharge is permitted

Explanation

The leaping-deer diamond is a warning that deer commonly cross the road in that area, so drivers should reduce speed and scan the shoulders, especially at dawn and dusk. It does not create a stop requirement or indicate a facility.

Question 29Road Signs

A yellow diamond sign shows a black symbol of a curve followed by a second arrow in the opposite direction. What condition does this sign warn of?

  1. A series of curves, beginning with the one shown Correct answer.
  2. A lane reduction on the right
  3. A dead-end road ahead
  4. A single gentle curve to the right

Explanation

When a warning diamond shows a curve arrow plus an additional arrow in the opposite direction, it indicates a series of curves rather than one bend. Drivers should expect changing steering direction and reduce speed accordingly.

Question 30Road Signs

A white rectangular sign with black lettering reads "ONE WAY" with an arrow. What does this sign tell the driver?

  1. Traffic on that roadway moves only in the direction of the arrow Correct answer.
  2. The road is closed to through traffic
  3. The roadway has one lane in each direction
  4. The driver must turn at the next intersection

Explanation

The ONE WAY sign with an arrow indicates that all traffic on that street flows in the arrow's direction. Drivers must not enter against the arrow. It says nothing about lane counts, mandatory turns, or closures.

Question 31Road Signs

An Iowa driver sees a yellow diamond sign with a black symbol of a tractor. What should the driver expect?

  1. A vehicle repair facility ahead
  2. A weigh station for commercial trucks
  3. A farm equipment crossing or slow-moving vehicle on the roadway Correct answer.
  4. A construction zone with heavy machinery

Explanation

The tractor symbol warns that slow-moving farm equipment may be crossing or traveling on the road. Drivers should slow down and be ready to pass only when it is legal and safe. In rural Iowa this warning is common during planting and harvest seasons.

Question 32Road Signs

A yellow diamond sign displays a black symbol of two arrows merging into one lane from the right. What is the driver in the right lane expected to do?

  1. Maintain speed and force other drivers to yield
  2. Merge left and yield to traffic already in the continuing lane Correct answer.
  3. Move onto the shoulder until traffic clears
  4. Stop immediately in the right lane

Explanation

The merge warning tells drivers in the ending lane that they must blend into the continuing lane and yield to vehicles already there. Stopping in a live lane or driving onto the shoulder creates new hazards. The safest response is to adjust speed early and find a gap.

Question 33Road Signs

An orange rectangular sign in a work zone reads "ROAD WORK AHEAD." What does the color orange signal to the driver?

  1. A temporary condition related to construction or maintenance Correct answer.
  2. A recreational or cultural point of interest
  3. A permanent regulatory requirement
  4. A hospital or emergency facility

Explanation

Orange is reserved for temporary traffic control in work zones, so an orange sign means construction or maintenance activity is affecting the road. Drivers should slow down, increase following distance, and watch for workers and equipment. Permanent regulations use white, and recreation uses brown.

Question 34Road Signs

A yellow diamond sign shows a black symbol of a traffic light with a red light illuminated. A driver approaching the intersection should prepare to do what?

  1. Accelerate to pass through before the light changes
  2. Stop, because the signal ahead may be red when reached Correct answer.
  3. Turn around because the road is closed
  4. Ignore the sign because it is only advisory for trucks

Explanation

A signal-ahead warning tells the driver that a traffic light controls the upcoming intersection, and the red indication on the symbol emphasizes stopping. The correct response is to slow and be ready to stop if the light is red. The sign is not advisory only for trucks.

Question 35Road Signs

A white rectangular sign with black lettering reads "NO RIGHT TURN." What does this regulatory sign prohibit?

  1. Turning right only during rush hour
  2. Turning right only if a pedestrian is present
  3. Turning right after a complete stop
  4. Turning right at that intersection under any circumstance Correct answer.

Explanation

The NO RIGHT TURN sign is a regulatory prohibition that applies at all times unless a supplemental plaque states otherwise. A driver who needs to go right must find another route. Stopping first does not make the turn legal.

Question 36Road Signs

A yellow diamond sign shows a black symbol of a divided highway ending, with two lanes joining into one undivided roadway. What change should the driver expect?

  1. The speed limit will increase automatically
  2. Opposing traffic will soon share the roadway without a median Correct answer.
  3. A passing lane will be added in the driver's direction
  4. The road will become a one-way street

Explanation

The divided-highway-ends warning tells drivers that the physical median separating opposing traffic is about to disappear. They should expect oncoming traffic close by and avoid passing unless permitted. The sign does not create a one-way street or add a lane.

Question 37Road Signs

A white rectangular sign with a red circle and slash over a black left-turn arrow appears at an intersection. How should the driver interpret it?

  1. Left turns are allowed only for buses
  2. Left turns are permitted only from the right lane
  3. Left turns must be made after stopping
  4. Left turns are prohibited at that intersection Correct answer.

Explanation

A red circle with a diagonal slash over a movement symbol is the standard prohibition marking. Combined with a left-turn arrow, it bans left turns at that location. The driver must choose another route or turn.

Question 38Road Signs

A yellow diamond sign with a black symbol of a pedestrian and a diagonal line through it appears near a school. What does this combination most likely indicate?

  1. A school bus stop is ahead
  2. A sidewalk ends ahead
  3. A pedestrian crossing is prohibited at that spot Correct answer.
  4. A pedestrian crossing exists ahead

Explanation

When a pedestrian symbol carries a diagonal slash, the marking negates the activity, meaning pedestrians are not to cross at that location. Drivers should still watch for people, but the crossing itself is closed. A plain pedestrian diamond without the slash would indicate a crossing ahead.

Question 39Road Signs

A blue rectangular sign with a white symbol of a telephone appears along an Iowa interstate. What service does this sign point to?

  1. A hospital emergency room
  2. A commercial truck weigh station
  3. A rest area with picnic tables
  4. A location where a telephone is available Correct answer.

Explanation

Blue signs mark motorist services, and the telephone symbol directs drivers to a phone. In the modern era this may be a call box or a facility with public phones. Hospital and rest area services use different symbols.

Question 40Road Signs

A yellow diamond sign shows a black symbol of a traffic signal with a green light illuminated. What should the driver understand about the upcoming intersection?

  1. The light is signal-controlled and may change before arrival Correct answer.
  2. The light will always be green when the driver arrives
  3. The intersection is uncontrolled
  4. The driver has the right-of-way permanently

Explanation

The signal-ahead warning alerts the driver that a light controls the intersection, and the green symbol does not guarantee the light will stay green. The driver should approach at a speed that allows stopping if the light changes. Assuming a permanent green is unsafe.

Question 41Road Signs

A white rectangular sign reads "KEEP RIGHT" with an arrow pointing to the right of a median. What does this sign require?

  1. Turn right at the next corner
  2. Stop before the median
  3. Pass to the right of the median or obstruction Correct answer.
  4. Merge right into the shoulder

Explanation

KEEP RIGHT is a regulatory sign directing traffic to pass on the right side of a median, island, or obstruction. It does not order a turn or a stop. Drivers should follow the arrow to stay in the correct travel path.

Question 42Road Signs

A yellow diamond sign shows a black symbol of a bridge with a narrow opening. What should the driver expect?

  1. A narrow bridge where lanes may be restricted Correct answer.
  2. A bridge with a weight limit of zero
  3. A tunnel with lighting ahead
  4. A bridge that is closed to traffic

Explanation

The narrow-bridge warning tells drivers that the bridge ahead has reduced clearance between lanes or edges. Drivers should slow and, if necessary, yield to oncoming traffic when the bridge cannot fit two vehicles comfortably. It does not mean the bridge is closed.

Question 43Road Signs

A yellow diamond sign shows a black symbol of a slippery road with a car and wavy skid marks. What is the best response?

  1. Reduce speed and avoid sudden braking or steering Correct answer.
  2. Maintain speed to keep traction steady
  3. Apply the brakes firmly on entering the area
  4. Accelerate to cross the slippery area quickly

Explanation

The slippery-when-wet warning indicates reduced traction, so the driver should slow before reaching the area and make gentle inputs. Sudden braking or steering can trigger a skid. Accelerating increases the risk of losing control.

Question 44Road Signs

A yellow diamond sign shows a black symbol of a hill with a percentage figure such as "6%." What does the percentage represent?

  1. The distance to the hill in miles
  2. The steepness of the grade ahead Correct answer.
  3. The speed limit on the hill
  4. The weight limit for trucks on the hill

Explanation

On a hill warning, the percentage expresses the grade, or steepness, of the descent or ascent. A 6% grade means the road drops or rises six feet for every 100 feet of travel. Drivers should adjust speed and gearing accordingly, especially with heavy loads.

Question 45Road Signs

A driver sees a yellow diamond sign with a black symbol of a road narrowing on both sides. What should the driver anticipate?

  1. A passing lane will open ahead
  2. A bridge will begin ahead
  3. The travel lanes will become narrower ahead Correct answer.
  4. The road will end ahead

Explanation

The road-narrows warning indicates that the pavement width is reduced, often because of construction, a bridge, or a change in cross section. Drivers should slow and stay centered in the lane. It is a warning, not a closure or lane addition.

Question 46Road Signs

An Iowa driver approaches a railroad crossing with a white crossbuck sign, flashing red lights, and a lowered gate. What is the required action?

  1. Stop and remain stopped until the gate rises and the lights stop flashing Correct answer.
  2. Drive around the gate if no train is visible
  3. Proceed slowly under the gate
  4. Stop only if a train horn is heard

Explanation

A lowered gate and flashing red lights mean a train is approaching, and the driver must stop and wait until the gate is fully raised and the lights stop flashing. Driving around or under a gate is illegal and extremely dangerous. Visibility of a train is not the test.

Question 47Road Signs

A yellow diamond sign with a black symbol of a school bus and the words "SCHOOL BUS STOP AHEAD" appears on a rural road. What should the driver do?

  1. Honk to warn children to stay off the road
  2. Stop immediately and wait for a bus to appear
  3. Slow down and watch for a stopped bus with flashing red lights and children Correct answer.
  4. Speed up to pass the area before a bus arrives

Explanation

The warning alerts drivers that school buses stop in the area, so they should reduce speed and be ready to stop for a bus displaying flashing red lights. Passing a stopped school bus with red lights flashing is illegal in Iowa. Honking or speeding up adds risk.

Question 48Road Signs

A white rectangular sign reads "DO NOT ENTER" at the top of a one-way ramp. A driver who has already passed the sign should take which action?

  1. Continue forward because the sign is only a suggestion
  2. Stop and back out or turn around only when it is safe to do so Correct answer.
  3. Shift into reverse and back down the ramp at speed
  4. Accelerate to reach the end of the ramp quickly

Explanation

DO NOT ENTER marks a roadway where traffic flows toward the driver, so continuing forward risks a head-on crash. The driver should stop as soon as it is safe, then back out or turn around carefully while watching for traffic. Reversing at speed or accelerating forward is dangerous.

Question 49Road Signs

A driver sees a yellow diamond sign with a black symbol of a flagger holding a paddle, and just beyond it a worker holds a paddle reading "SLOW." What is the correct response?

  1. Continue at the posted speed because the sign is only a warning
  2. Sound the horn and maintain speed through the zone
  3. Stop and wait for the flagger to approach the vehicle
  4. Reduce speed and proceed with caution as directed by the flagger Correct answer.

Explanation

A SLOW paddle directs drivers to reduce speed and continue carefully, while a STOP paddle would require a halt. The flagger's instructions control traffic through the work zone. Ignoring the paddle or maintaining speed endangers workers.

Question 50Road Signs

A yellow diamond sign shows a black symbol of a lane with a left-turn arrow and a through arrow, with the through arrow crossed by a diagonal line. What does this configuration warn the driver?

  1. The left turn will be prohibited at the intersection
  2. The through movement will end and only the turn will remain available Correct answer.
  3. The left-turn lane will merge into the through lane
  4. The through lane will be added ahead

Explanation

When the through arrow carries a slash while the turn arrow remains, the through movement is being removed and traffic must turn. Drivers intending to continue straight need to change lanes or route early. A slash over the turn arrow instead would forbid the turn.
