Question 1Road Signs (regulatory, warning, guide)

Under Louisiana law, a steady red circular traffic signal means a driver must come to a complete stop before which reference point?

  1. The far side of the intersection
  2. The next curb cut or driveway
  3. The nearest crosswalk, stop line, or entrance to the intersecting roadway Correct answer.
  4. The center of the intersection

Explanation

A steady red signal requires a full stop at the marked stop line, or at the crosswalk if there is one, or before entering the intersecting roadway when neither marking exists. Stopping anywhere else defeats the purpose of controlling entry into the intersection.

Question 2Road Signs (regulatory, warning, guide)

A flashing red traffic signal at an intersection should be treated in the same manner as which of the following?

  1. A stop sign Correct answer.
  2. A yield sign
  3. A flashing yellow signal
  4. A green arrow

Explanation

A flashing red light requires a complete stop, then proceeding only when the way is clear, which is exactly the rule for a stop sign. A flashing yellow, by contrast, only warns drivers to slow and proceed with caution.

Question 3Road Signs (regulatory, warning, guide)

A yellow circular traffic signal indicates that a driver should:

  1. Yield only to vehicles already inside the intersection
  2. Prepare to stop because the signal is about to turn red Correct answer.
  3. Stop immediately at the signal head
  4. Speed up to clear the intersection

Explanation

A steady yellow signal warns that the green interval is ending and red will follow. Drivers should clear the intersection if already inside it or stop safely if they can do so, but the signal never authorizes acceleration.

Question 4Road Signs (regulatory, warning, guide)

A white rectangular sign with black lettering reading "SPEED LIMIT 45" is best classified as which type of sign?

  1. Construction
  2. Regulatory Correct answer.
  3. Guide
  4. Warning

Explanation

Speed limit signs are regulatory because they impose a legal requirement that drivers must obey. Warning signs are typically yellow diamonds, and guide signs are usually green, blue, or brown.

Question 5Road Signs (regulatory, warning, guide)

An octagonal sign is reserved in the United States for which single message?

  1. Stop Correct answer.
  2. Railroad crossing
  3. Do not enter
  4. Yield

Explanation

The eight-sided octagon is used exclusively for STOP signs so that drivers can recognize the sign by shape alone, even when it is obscured by snow or distance. No other message uses the octagon.

Question 6Road Signs (regulatory, warning, guide)

A downward-pointing triangle sign with a red border and white center tells a driver to:

  1. Stop completely before proceeding
  2. Merge without changing speed
  3. Prepare for a signal ahead
  4. Slow down and give the right-of-way to traffic on the intersecting road Correct answer.

Explanation

The inverted triangle is the yield sign, which requires a driver to slow and let cross traffic and pedestrians go first, stopping only if necessary. Unlike a stop sign, a full stop is not always mandatory.

Question 7Road Signs (regulatory, warning, guide)

A yellow diamond-shaped sign with a black symbol of a curving arrow warns a driver about:

  1. A winding road or curve ahead Correct answer.
  2. A lane reduction ahead
  3. A slippery pavement section
  4. A pedestrian crossing

Explanation

Yellow diamond signs are warning signs, and a curving arrow symbol indicates a curve or winding road ahead where reduced speed may be needed. The diamond shape itself signals a warning rather than a regulation.

Question 8Road Signs (regulatory, warning, guide)

A circular sign with a yellow background, a black "X," and black "RR" letters is placed in advance of what?

  1. A weigh station
  2. A roundabout
  3. A railroad crossing Correct answer.
  4. A highway entrance ramp

Explanation

This circular advance warning sign alerts drivers that a railroad crossing is ahead, giving them time to slow and look for trains. It is posted before the crossing itself, where the crossbuck and pavement markings appear.

Question 9Road Signs (regulatory, warning, guide)

A driver approaching a steady red arrow pointing left wants to turn left from a one-way street onto another one-way street. What does Louisiana law allow?

  1. The turn is prohibited under all circumstances
  2. The turn may be made after a complete stop if no traffic or pedestrians are in the way Correct answer.
  3. The turn may be made only after the arrow changes to green
  4. The turn may be made without stopping if the way is clear

Explanation

A red arrow prohibits movement in the direction indicated until a stop is made and the way is clear, and left turns from a one-way street onto another one-way street are permitted after that stop. The arrow controls the movement but does not permanently forbid it.

Question 10Road Signs (regulatory, warning, guide)

A white rectangular sign shows a black symbol of a car with two wavy skid marks behind it. What is the correct driver response?

  1. Reduce speed and avoid abrupt braking or steering Correct answer.
  2. Stop immediately and wait for conditions to improve
  3. Increase speed to maintain traction
  4. Shift to a lower gear and accelerate gently

Explanation

This is the slippery-when-wet warning sign, and the appropriate response is to slow down and make smooth inputs so the tires retain grip. Hard braking or sudden steering on a slick surface is what causes the skid the sign warns about.

Question 11Road Signs (regulatory, warning, guide)

A yellow diamond sign depicts a pedestrian within a diagonal slash. What does this sign communicate?

  1. A school crossing is ahead
  2. Pedestrians are prohibited from crossing here Correct answer.
  3. A hiking trail crosses the roadway
  4. A pedestrian crossing is ahead

Explanation

A diagonal slash across a symbol negates that symbol, so a slashed pedestrian means pedestrians are not permitted to cross at that location. An unslashed pedestrian symbol on a yellow diamond would instead warn of a crossing ahead.

Question 12Road Signs (regulatory, warning, guide)

A green highway guide sign lists a city name with a distance in miles. What information is the sign conveying?

  1. The remaining length of the construction zone
  2. The distance to the nearest rest area
  3. The distance to the named destination Correct answer.
  4. The distance to the next exit only

Explanation

Green guide signs provide destination and distance information so drivers can plan their route. The mileage shown is the distance to the named place, not to an exit, work zone, or service facility.

Question 13Road Signs (regulatory, warning, guide)

A blue rectangular sign along an interstate displays symbols for fuel, food, and lodging. Its purpose is to:

  1. Warn of a reduced-speed zone
  2. Mark the boundary of a scenic byway
  3. Indicate a mandatory truck route
  4. Identify available services at an upcoming exit Correct answer.

Explanation

Blue signs are service signs, and their symbols tell drivers which amenities are available at or near an upcoming exit. They are informational and do not impose any driving requirement.

Question 14Road Signs (regulatory, warning, guide)

An orange diamond sign reading "ROAD WORK AHEAD" appears on a rural highway. What adjustment should a driver make?

  1. Sound the horn continuously through the zone
  2. Move to the shoulder until the zone ends
  3. Maintain the posted speed to keep traffic flowing
  4. Slow down and watch for workers, equipment, and narrowed lanes Correct answer.

Explanation

Orange signs mark construction and maintenance zones, where speeds are often reduced and lanes may shift. Drivers should slow and stay alert for workers and equipment rather than assuming normal conditions apply.

Question 15Road Signs (regulatory, warning, guide)

A white rectangular sign with black text reading "KEEP RIGHT" is best described as:

  1. A guide sign showing a destination
  2. A recreational sign
  3. A warning sign about a curve
  4. A regulatory sign that must be obeyed Correct answer.

Explanation

KEEP RIGHT is a regulatory sign because it directs a required action with legal force. White rectangular signs with black text generally impose rules rather than merely advising of conditions.

Question 16Road Signs (regulatory, warning, guide)

A driver sees a sign with a black "X" and the letters "RR" on a yellow circular background, followed by a crossbuck at the tracks. If a train is approaching, the driver must:

  1. Stop at least 15 feet but no more than 50 feet from the nearest rail Correct answer.
  2. Proceed because the crossbuck grants priority
  3. Stop directly on the tracks to check both directions
  4. Slow to 25 mph and continue across

Explanation

At a railroad crossing, a driver must stop within the statutory distance range from the nearest rail when a train is approaching or signals are active. Stopping too close or on the tracks leaves the vehicle in the path of the train.

Question 17Road Signs (regulatory, warning, guide)

A pentagon-shaped sign (point up) with a black symbol of children is used to indicate:

  1. A playground inside a park
  2. A bicycle route
  3. A pedestrian mall
  4. A school zone or school crossing Correct answer.

Explanation

The pentagon shape is used specifically for school-related signs, and the children symbol marks a school zone or crossing. Drivers should slow and watch for children who may enter the roadway unpredictably.

Question 18Road Signs (regulatory, warning, guide)

A red circle with a diagonal slash over a black arrow pointing left means:

  1. Left turns are permitted after a stop
  2. A left curve is ahead
  3. Left lane ends ahead
  4. Left turns are prohibited Correct answer.

Explanation

A red circle with a diagonal slash is the universal prohibition symbol, so a slashed left arrow forbids left turns at that location. The arrow alone would indicate the direction of the movement being regulated.

Question 19Road Signs (regulatory, warning, guide)

A sign reading "DO NOT PASS" with a black left-pointing arrow appears on a two-lane road. What does it require?

  1. No passing where the sign is posted, in the direction of travel Correct answer.
  2. Passing allowed for trucks only
  3. No passing in either direction for the next mile
  4. Passing allowed only when the centerline is dashed

Explanation

A DO NOT PASS sign is a regulatory sign that forbids passing in the direction of travel at that location, usually because of limited sight distance. It applies to the traffic facing the sign, not to opposing traffic.

Question 20Road Signs (regulatory, warning, guide)

A white rectangular sign reads "STOP HERE ON RED." What is the practical effect of this sign at a signalized intersection?

  1. Drivers must stop at the sign before proceeding on red, then may continue when clear Correct answer.
  2. Drivers must wait for a green signal before moving at all
  3. Drivers must turn right only
  4. Drivers may treat the signal as a yield

Explanation

This sign marks the point where a driver must stop before making a permitted movement on red, such as a right turn on red. It fixes the stop location so the vehicle does not encroach on the crosswalk or cross traffic.

Question 21Road Signs (regulatory, warning, guide)

A yellow diamond sign shows a black arrow curving to the right with a smaller advisory speed plaque reading "25 MPH" beneath it. How should a driver interpret the advisory speed?

  1. It is the minimum speed permitted in the curve
  2. It applies only to trucks and buses
  3. It is the legal maximum for the curve
  4. It is a recommended speed for the curve under normal conditions Correct answer.

Explanation

An advisory speed plaque on a warning sign recommends a safe speed for the condition shown, such as a curve, rather than setting a legally enforced limit. Drivers may travel slower, and conditions such as rain may call for even less speed.

Question 22Road Signs (regulatory, warning, guide)

A green overhead sign on an interstate shows a lane-use arrow pointing down with a red "X" above one lane. What does the red X indicate for that lane?

  1. The lane is an exit-only lane
  2. The lane is reserved for high-occupancy vehicles
  3. The lane is closed and must not be used Correct answer.
  4. The lane is for trucks only

Explanation

In lane-use control signals, a red X marks a lane that is closed to traffic, while a downward green arrow marks an open lane. Drivers must move out of a lane displaying the red X.

Question 23Road Signs (regulatory, warning, guide)

A brown rectangular sign with white text identifies a state park entrance. Why are recreational signs given a distinct color?

  1. To mark the start of a reduced-speed zone
  2. To distinguish points of interest from regulatory and warning information Correct answer.
  3. To warn drivers of hazardous conditions
  4. To indicate that parking is prohibited

Explanation

Brown is reserved for recreational and cultural interest signs so drivers can quickly separate points of interest from rules and hazards. The color coding lets a driver scan a sign's purpose before reading its text.

Question 24Road Signs (regulatory, warning, guide)

A driver on a two-lane road sees a "NO PASSING ZONE" pennant sign on the left side of the road facing oncoming traffic. What does this tell the driver about their own passing privileges?

  1. Passing is permitted if the centerline is dashed
  2. Passing is prohibited for the driver in the direction the pennant faces Correct answer.
  3. Passing is prohibited for both directions of traffic
  4. Passing is permitted only for emergency vehicles

Explanation

The pennant-shaped NO PASSING ZONE sign is mounted on the left side of the road to face traffic coming the other way, so it governs passing for that opposing direction. A driver seeing its back should not assume it restricts their own passing.

Question 25Road Signs (regulatory, warning, guide)

A white rectangular sign displays a black symbol of a traffic signal. What is the sign warning drivers to expect?

  1. A pedestrian signal at a crosswalk
  2. A railroad crossing with signals
  3. A flashing yellow beacon at a fire station
  4. A traffic signal ahead that may require a stop Correct answer.

Explanation

The signal-ahead warning sign alerts drivers that a traffic signal is coming up so they can prepare to stop if the light is red. It is a warning sign, typically yellow, rather than a regulatory command.

Question 26Road Signs (regulatory, warning, guide)

A white rectangular sign with black text reading 'ONE WAY' and a right-pointing arrow is posted at an intersection. What does this sign tell a driver?

  1. Drivers must turn right because the street is a dead end
  2. The roadway ahead ends and merges into a two-way street
  3. Traffic on that roadway moves only in the direction of the arrow Correct answer.
  4. A right turn is prohibited at the upcoming intersection

Explanation

The ONE WAY sign is a regulatory sign that marks a roadway carrying traffic in a single direction, and the arrow shows that direction. It does not command a turn; it informs drivers that all traffic on that street flows one way.

Question 27Road Signs (regulatory, warning, guide)

A yellow diamond sign shows a black symbol of a divided highway ending, with the two roadways converging into one. What should the driver expect?

  1. A new median will open and separate opposing traffic
  2. The separated roadways will merge into a single two-way roadway Correct answer.
  3. The road will become a one-way street in the same direction
  4. An exit ramp will split off to the right

Explanation

This warning sign announces the end of a divided highway, meaning the two separated roadways come together into one roadway carrying both directions. Drivers should be alert for oncoming traffic after the merge point.

Question 28Road Signs (regulatory, warning, guide)

A white rectangular sign with black text reading 'YIELD AHEAD' is placed before an intersection. What does it require of the driver?

  1. Come to a complete stop before the sign itself
  2. Prepare to slow and give the right-of-way at the upcoming yield point Correct answer.
  3. Sound the horn before entering the intersection
  4. Accelerate to merge ahead of cross traffic

Explanation

The word message YIELD AHEAD is an advance warning that a yield sign or yield condition is coming up, so the driver should begin slowing and prepare to give way. The actual yield requirement applies at the yield point, not at the advance sign.

Question 29Road Signs (regulatory, warning, guide)

A yellow diamond sign shows a black symbol of a tractor pulling a plow. What hazard does this sign warn of?

  1. A construction zone with heavy machinery begins ahead
  2. A livestock auction facility is located at the next exit
  3. A weigh station for commercial trucks is ahead
  4. Slow-moving farm equipment may be crossing or traveling on the road Correct answer.

Explanation

The farm machinery warning sign alerts drivers that slow-moving agricultural equipment may be operating on or crossing the roadway. Drivers should reduce speed and be ready to stop behind equipment that cannot travel at highway speeds.

Question 30Road Signs (regulatory, warning, guide)

A white rectangular sign with black text reading 'SPEED LIMIT 45' is posted on a rural road. What does this sign establish?

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

Explanation

A SPEED LIMIT sign is regulatory and sets the maximum lawful speed for that roadway under normal conditions. Drivers may travel slower when conditions or safety require it.

Question 31Road Signs (regulatory, warning, guide)

A driver sees a yellow diamond sign showing a black arrow that bends sharply to the left, followed by a smaller yellow plaque reading '20 MPH.' How should the driver use the plaque?

  1. As the recommended maximum speed for the curve under good conditions Correct answer.
  2. As the speed at which the curve becomes unsafe in rain only
  3. As the minimum speed required to hold the lane
  4. As the legal speed limit for the entire road segment

Explanation

An advisory speed plaque gives a recommended safe speed for the specific feature, here a sharp curve, when conditions are good. It is guidance rather than the posted legal limit, and drivers should slow further in rain, ice, or poor visibility.

Question 32Road Signs (regulatory, warning, guide)

A red circular sign with a diagonal slash over a black symbol of a truck is posted on a roadway. What does this sign mean?

  1. Trucks may proceed only with a permit
  2. A truck weigh station is ahead
  3. Trucks are prohibited from using this roadway Correct answer.
  4. Trucks must use the left lane only

Explanation

A red circle with a diagonal slash is the universal prohibition symbol, and the symbol inside identifies what is banned. Here the truck symbol means trucks are not allowed on that roadway.

Question 33Road Signs (regulatory, warning, guide)

A green guide sign on a rural highway reads 'EXIT 12 - 1 MILE' with a right-pointing arrow. What should the driver understand?

  1. The exit is at mile marker 12 on the left
  2. The exit ramp is closed for one mile
  3. The exit was one mile back on the right
  4. The exit is one mile ahead on the right Correct answer.

Explanation

Green guide signs give destination and distance information, and the arrow shows the direction of the exit. The distance shown is measured from the sign to the exit point.

Question 34Road Signs (regulatory, warning, guide)

A white rectangular sign with black text reads 'LEFT LANE MUST TURN LEFT' above an intersection. What does this sign require?

  1. Vehicles in the left lane may continue straight or turn left
  2. All vehicles must move to the left lane before the intersection
  3. Vehicles in the left lane must turn left when they reach the intersection Correct answer.
  4. Left turns are prohibited from the left lane

Explanation

This is a mandatory movement regulatory sign: it directs vehicles already in the left lane to turn left at the intersection. Drivers who intend to go straight should move out of that lane beforehand.

Question 35Road Signs (regulatory, warning, guide)

A yellow diamond sign shows a black symbol of a traffic signal with a red light illuminated. What should the driver expect?

  1. A signalized intersection ahead where stopping may be required Correct answer.
  2. A pedestrian crossing with a flashing beacon ahead
  3. A lane-control signal that closes the left lane
  4. A railroad crossing with flashing lights ahead

Explanation

The signal-ahead warning sign alerts drivers that a traffic signal controls the upcoming intersection, so they should be prepared to stop. It is especially important where sight distance is limited or where the signal is new.

Question 36Road Signs (regulatory, warning, guide)

A driver encounters a yellow diamond sign showing a black symbol of a road narrowing on both sides. What is the correct response?

  1. Expect the road to widen into additional lanes
  2. Reduce speed and prepare for less shoulder and lane width ahead Correct answer.
  3. Maintain speed because the lane width is unchanged
  4. Move to the right shoulder to let others pass

Explanation

The road-narrows sign warns that the traveled way becomes narrower, often with reduced shoulders or lane width. Drivers should slow down and adjust position to keep a safe margin from the edge and from other vehicles.

Question 37Road Signs (regulatory, warning, guide)

A blue rectangular sign on a freeway shows a white symbol of an airplane. What does this sign indicate?

  1. A military base entrance is ahead
  2. An airport is accessible from this exit Correct answer.
  3. A rest area with an observation deck is ahead
  4. Aircraft may be crossing the freeway overhead

Explanation

Blue signs provide motorist services information, and the airplane symbol points travelers toward an airport reached via the indicated exit. It is a service guide, not a hazard warning.

Question 38Road Signs (regulatory, warning, guide)

A white rectangular sign with black text reads 'NO RIGHT TURN ON RED.' What does this sign change about a driver's normal options at the intersection?

  1. It prohibits right turns at all times, including on green
  2. It removes the permission to turn right while the signal is red Correct answer.
  3. It requires a right turn only when the light is red
  4. It allows a right turn after a full stop only

Explanation

Where right turn on red is otherwise permitted, this regulatory sign withdraws that permission, so the driver must wait for a green signal to turn right. It does not ban right turns on green.

Question 39Road Signs (regulatory, warning, guide)

A yellow diamond sign shows a black symbol of a large arrow with a smaller arrow branching off to the right. What does this sign warn of?

  1. A divided highway beginning with a raised median
  2. An added lane or a merge where traffic may enter from the right Correct answer.
  3. A right lane that ends and forces a merge left
  4. A right turn only lane at the next intersection

Explanation

The added-lane or merge warning shows that another lane joins the roadway, so drivers should watch for vehicles entering from the right and adjust speed or lane position. It is a warning of a traffic-flow change, not a mandatory turn.

Question 40Road Signs (regulatory, warning, guide)

A white rectangular sign with black text reading 'BRIDGE FREEZES BEFORE ROADWAY' is a warning to drivers in cold weather. Which statement best explains the sign's purpose?

  1. It indicates that the bridge is closed during freezing weather
  2. It alerts drivers that bridge surfaces can become icy sooner than the adjoining pavement Correct answer.
  3. It requires chains on all vehicles crossing the bridge
  4. It marks a weight limit that applies in winter

Explanation

Bridges lose heat from both the deck and the air beneath, so their surfaces can freeze before the adjacent roadway does. The sign warns drivers to slow down and expect ice on the bridge even when the road before it appears clear.

Question 41Road Signs (regulatory, warning, guide)

A driver on a multi-lane road sees a white rectangular sign with black text reading 'KEEP RIGHT EXCEPT TO PASS.' What does this sign direct?

  1. Move right only when an emergency vehicle approaches
  2. Stay in the left lane unless passing on the right
  3. Pass only on the right shoulder
  4. Drive in the right lane and use left lanes only for passing Correct answer.

Explanation

This regulatory sign establishes that the right lane is the normal travel lane and left lanes are reserved for overtaking. It supports smoother traffic flow and reduces conflicts from slower traffic lingering in left lanes.

Question 42Road Signs (regulatory, warning, guide)

A yellow diamond sign displays a black symbol of a bicycle. What should a driver anticipate?

  1. A bicycle shop or rental facility is at the next exit
  2. Bicycles are prohibited beyond this point
  3. A dedicated bike path runs parallel with no roadway crossing
  4. Bicyclists may be sharing or crossing the roadway ahead Correct answer.

Explanation

The bicycle warning sign alerts motorists that cyclists may be on or crossing the road, so they should slow down and give riders room. It is a hazard warning rather than a services or prohibition sign.

Question 43Road Signs (regulatory, warning, guide)

A white rectangular sign with black text reading 'DO NOT ENTER' is posted facing a driver at the end of a one-way street. What must the driver do?

  1. Proceed slowly if no traffic is visible
  2. Continue only if the destination is on that block
  3. Yield to traffic already in the roadway and proceed
  4. Stop and turn around, because travel in that direction is prohibited Correct answer.

Explanation

DO NOT ENTER marks a roadway where traffic moves toward the driver, so entering would mean traveling against the flow. The driver must not proceed and should find a lawful route.

Question 44Road Signs (regulatory, warning, guide)

A yellow diamond sign shows a black symbol of a truck on a steep downgrade with the text 'TRUCKS USE LOW GEAR.' What is the sign's purpose?

  1. To announce a truck inspection station at the bottom
  2. To indicate a truck route that bypasses the grade
  3. To require all vehicles to shift into low gear
  4. To warn drivers that heavy vehicles may be moving slowly on a long descent Correct answer.

Explanation

The sign warns that trucks descending a steep grade may travel slowly and may need to use lower gears to control speed. Other drivers should be prepared to encounter slow-moving heavy vehicles and should avoid cutting in front of them.

Question 45Road Signs (regulatory, warning, guide)

A green guide sign on an interstate lists three destinations in order with distances of 12, 30, and 55 miles. What does this sign help a driver do?

  1. Choose a lane based on the next exit only
  2. Plan ahead by showing how far each destination is along the route Correct answer.
  3. Identify the speed limit changes between cities
  4. Locate service plazas between the cities

Explanation

Distance guide signs list destinations with mileage so drivers can anticipate travel time and plan stops or lane changes well in advance. They are informational guide signs, not regulatory or warning signs.

Question 46Road Signs (regulatory, warning, guide)

A driver sees a yellow diamond sign showing a black symbol of a curve first to the right and then to the left, with a '35 MPH' advisory plaque. What does the combination tell the driver?

  1. A reverse curve is ahead and about 35 mph is the recommended speed through it Correct answer.
  2. The road becomes a two-way street in 35 miles
  3. The legal speed limit drops to 35 mph at the curve
  4. A passing lane opens 35 miles ahead

Explanation

The reverse-curve symbol shows the road bending one way and then the other, and the yellow advisory plaque gives a recommended speed for that feature under good conditions. Drivers should slow before entering the first curve because the second follows immediately.

Question 47Road Signs (regulatory, warning, guide)

A white rectangular sign with black text reading 'CROSSWALK AHEAD' appears before a marked pedestrian crossing. How should a driver respond?

  1. Maintain speed because pedestrians must yield to vehicles
  2. Sound the horn to warn pedestrians to stay back
  3. Slow down and be prepared to stop for pedestrians in the crossing Correct answer.
  4. Stop completely at the sign before continuing

Explanation

The sign alerts drivers to an upcoming crosswalk so they can reduce speed and watch for pedestrians. Drivers must yield to pedestrians in a marked crosswalk, and stopping may be required.

Question 48Road Signs (regulatory, warning, guide)

A yellow diamond sign shows a black symbol of a car with the word 'SLIPPERY WHEN WET' on a plaque below. What is the safest interpretation?

  1. Traction is reduced on this surface during rain, so slow down before it rains Correct answer.
  2. The surface is slippery only in freezing temperatures
  3. The sign applies only to vehicles towing trailers
  4. The road is closed whenever it is wet

Explanation

The slippery-when-wet warning identifies a pavement that loses traction in wet conditions, such as a bridge deck or an oil-glazed surface. Drivers should reduce speed before the surface becomes wet and avoid abrupt braking or steering.

Question 49Road Signs (regulatory, warning, guide)

A driver approaches a yellow diamond sign showing a black symbol of a deer. What is the most appropriate action, especially near dawn or dusk?

  1. Accelerate to pass through the area quickly
  2. Move to the left lane and maintain speed
  3. Stop and wait until daylight before continuing
  4. Reduce speed and scan the shoulders for animals entering the road Correct answer.

Explanation

The deer warning sign marks an area where animals frequently cross, and deer are most active around dawn and dusk. Slowing down and scanning the shoulders gives the driver more time to react if an animal steps into the roadway.

Question 50Road Signs (regulatory, warning, guide)

A driver sees a white rectangular sign reading 'WEIGHT LIMIT 10 TONS' on a bridge approach. Which driver is affected by this regulatory sign?

  1. Only drivers of vehicles registered out of state
  2. The operator of a vehicle or combination whose weight exceeds the posted limit Correct answer.
  3. All drivers, because the sign sets a minimum weight
  4. Only drivers carrying hazardous materials

Explanation

A weight limit sign is regulatory and restricts vehicles above the stated gross weight from using the bridge or roadway. Overweight vehicles must use an alternate route to avoid structural damage and penalties.
