Question 1Vehicle Load

Un conductor debe transportar a un niño menor de un año en el asiento trasero. ¿Cuál es la medida de seguridad pasiva más adecuada?

  1. Llevarlo en brazos de un adulto que ocupe el asiento trasero
  2. Utilizar una silla de seguridad adecuada a su talla y peso, instalada en el asiento trasero Correct answer.
  3. Sentarlo en el asiento delantero con el cinturón puesto
  4. Usar el cinturón de seguridad de adultos ajustado sobre el cuerpo del niño

Explanation

Los niños pequeños deben viajar en un sistema de retención infantil homologado, acorde a su talla y peso, instalado preferentemente en el asiento trasero. El cinturón de adultos no se ajusta al cuerpo de un menor de un año y puede causar lesiones graves en una frenada. Los brazos de un adulto no contienen al niño frente a la fuerza de una desaceleración.

Question 2Incident Environment

Under the Ley de Tránsito, what is a driver who has taken part in a crash in which someone is injured or killed legally required to do?

  1. Continue to the nearest town and report the crash within 48 hours
  2. Stop, give whatever help is possible, and report to the nearest police authority Correct answer.
  3. Wait for the other driver to call the police, because only the party at fault has a duty to report
  4. Move all injured people into a vehicle and drive them away before contacting anyone

Explanation

The Ley de Tránsito imposes three duties on a driver involved in a crash with injuries or death: halt the vehicle, render whatever assistance is possible, and give notice to the nearest police authority. Any Carabinero near the scene counts for this purpose. Leaving the scene is treated severely: the law presumes the responsibility of a driver who fails to comply and abandons the place, and fleeing a crash with injuries is one of the offences created by Ley 20.770, known as Ley Emilia.

Question 3Priority Signs

Under Chilean Traffic Law (Ley 18.290), what is the general statutory maximum speed limit for light vehicles in urban zones (zona urbana) unless otherwise signposted?

  1. 40 km/h
  2. 50 km/h Correct answer.
  3. 60 km/h
  4. 70 km/h

Explanation

Under Ley 21.088 (which amended Ley 18.290 in 2018), the statutory maximum speed limit for light passenger vehicles in urban areas in Chile is 50 km/h, reduced from the historical 60 km/h limit to improve pedestrian and cyclist safety.

Question 4Priority Signs

Under Ley de Convivencia Vial (Ley 21.088), what is the minimum lateral clearance a motor vehicle driver must maintain when overtaking a cyclist?

  1. 0.5 meters
  2. 1.0 meter
  3. 1.5 meters Correct answer.
  4. 2.0 meters

Explanation

Ley 21.088 establishes that motor vehicle drivers must maintain a minimum lateral separation distance of at least 1.5 meters when passing or overtaking cyclists and users of personal mobility devices on public roads.

Question 5Priority Signs

At an uncontrolled four-way intersection where two vehicles approach simultaneously from different streets, who has the right-of-way (derecho preferente de paso)?

  1. The vehicle approaching from the left of the other driver
  2. The vehicle approaching from the right of the other driver Correct answer.
  3. The heavier or larger vehicle
  4. The vehicle that reaches the highest speed before entering

Explanation

Under Article 139 of Ley 18.290, at intersections where traffic is not regulated by traffic lights, police officers, or Stop/Yield signs, the driver approaching from the left must yield right-of-way to the vehicle approaching from their right (the right-hand priority rule).

Question 6Priority Signs

Who has the right-of-way when entering a roundabout (rotonda) in Chile?

  1. The vehicle entering the roundabout has priority over vehicles already inside
  2. The vehicle already circulating inside the roundabout has right-of-way over vehicles wishing to enter Correct answer.
  3. The vehicle traveling in the outermost lane always has priority regardless of position
  4. Vehicles entering from the north or east always have priority

Explanation

The CONASET Libro para la Conducción en Chile states the duty directly: on reaching a roundabout you are obliged to give way to the vehicles already circulating in it. Article 124 of the Ley de Tránsito adds the direction of travel, requiring vehicles in a zona de tránsito en rotación (monuments, squares, roundabouts) to pass to the right of the island, leaving it on their left, unless signs indicate otherwise. The manual also advises deciding your exit early so you enter in the correct lane and signal right after passing the exit before yours.

Question 7Priority Signs

How is a lower speed limit than 50 km/h, such as a 30 km/h limit outside a school, legally established on a Chilean urban street?

  1. The Ley de Tránsito itself fixes a nationwide 30 km/h limit for every school and hospital frontage
  2. The municipality may raise or lower the statutory limit for a specific road, or declare a 'zona de tránsito calmado', and the change takes effect through official signage Correct answer.
  3. Any driver may choose a lower limit and the police must accept it
  4. Only the Dirección de Vialidad may change limits, and only on rural roads

Explanation

Article 145 of the Ley de Tránsito fixes only the general maximum limits (50 km/h urban, 100 or 120 km/h rural, and lower caps for buses and heavy trucks). Article 146 is what allows a lower figure: municipalities in urban areas, and the Dirección de Vialidad in rural areas, may raise or lower the limit for a given road on justified grounds, and municipalities may also establish 'zonas de tránsito calmado'. The modified limit is legally effective only once it is shown by official signs, which is why the driver's duty is to read the posted sign rather than assume a nationwide figure.

Question 8Priority Signs

What is the statutory speed limit on rural roads with one lane per direction for light passenger cars in Chile?

  1. 80 km/h
  2. 90 km/h
  3. 100 km/h Correct answer.
  4. 120 km/h

Explanation

Under Article 145 of Ley 18.290, the maximum statutory speed limit on rural roads (caminos o carreteras) with a single travel lane in each direction is 100 km/h for light vehicles.

Question 9Priority Signs

What is the maximum speed limit for light passenger vehicles on rural highways or motorways (autopistas) with two or more lanes in each direction in Chile?

  1. 100 km/h
  2. 110 km/h
  3. 120 km/h Correct answer.
  4. 130 km/h

Explanation

Under Article 145 of Ley 18.290, the maximum statutory speed limit on rural routes and expressways having two or more lanes in the same direction of travel is 120 km/h for light vehicles.

Question 10Priority Signs

What does a broken/dashed line (línea discontinua) parallel to a solid line on a two-lane road mean for a driver traveling on the side of the broken line?

  1. The driver may cross the line to overtake when conditions are safe and clear Correct answer.
  2. The driver is prohibited from crossing the line under any circumstances
  3. The road is permanently closed ahead
  4. The driver must immediately stop on the shoulder

Explanation

When a solid line and a dashed line run in parallel, drivers traveling on the side of the dashed line may cross it to overtake when visibility and oncoming traffic permit, while drivers on the side of the solid line cannot.

Question 11Priority Signs

What does a triangular sign with a red border, white background, and the word 'CEDA EL PASO' instruct a driver to do?

  1. Come to a complete stop only if another car is within 5 meters
  2. Slow down and yield right-of-way to all vehicles and pedestrians on the intersecting road, stopping completely if necessary Correct answer.
  3. Accelerate to merge into traffic ahead of approaching vehicles
  4. Maintain speed because the driver has priority

Explanation

The 'CEDA EL PASO' (Yield) sign requires drivers to reduce speed and yield priority to all vehicles and pedestrians crossing on the intersecting roadway, stopping completely if oncoming traffic requires it.

Question 12Priority Signs

What must a driver do when facing an octagonal red sign with white letters reading 'PARE' (Stop)?

  1. Slow down and roll through the intersection if no cars are visible
  2. Come to a mandatory, complete stop before the stop line, zebra crossing, or intersection entrance, and proceed only when clear Correct answer.
  3. Stop only if a police officer is present
  4. Sound the horn and proceed with caution

Explanation

A 'PARE' sign mandates a complete and total cessation of vehicle movement before the marked stop line or pedestrian crossing. Rolling stops are illegal and constitute a grave traffic violation in Chile.

Question 13Priority Signs

What does a flashing yellow traffic light (luz amarilla intermitente) indicate to an approaching driver?

  1. The traffic light is broken and drivers must stop completely
  2. It warns of danger (advierte peligro): approach with caution and at a speed that lets you react to the hazard the signal is flagging Correct answer.
  3. Accelerate quickly before the light turns solid red
  4. It has the same legal meaning as CEDA EL PASO

Explanation

Article 104 of the Ley de Tránsito defines the flashing indications, and it says simply that a flashing yellow light 'advierte peligro' - it warns of danger. It does not create the specific give-way duty that a flashing red (CEDA EL PASO) creates, and it does not order a stop. The driver reduces speed and approaches ready to react to whatever hazard the signal is marking.

Question 14Priority Signs

What does a single flashing red traffic light (una luz roja intermitente) indicate to an approaching driver in Chile?

  1. It has the same meaning as a PARE sign, so a complete stop is always legally required
  2. It means CEDA EL PASO: reduce speed, give way to traffic on the other road, and stop only if necessary to avoid a risk of collision Correct answer.
  3. The driver should maintain speed and yield only to emergency vehicles
  4. The light is out of service and may be disregarded

Explanation

Article 104 of the Ley de Tránsito lists the meaning of each signal indication, and it states that a single flashing red light indicates 'CEDA EL PASO'. The CONASET Libro para la Conducción en Chile repeats this wording. A driver therefore slows down and yields to traffic on the intersecting road, stopping only where proximity creates a risk of collision. Two alternating flashing red lights are a different indication and do require stopping before the stop line; they are used at level railway crossings and to give priority to fire or ambulance vehicles entering the road.

Question 15Priority Signs

What is the main safety function of the Anti-lock Braking System (ABS) during emergency braking?

  1. To reduce braking distance to zero in all circumstances
  2. To prevent the wheels from locking up, allowing the driver to maintain steering control while braking with maximum force Correct answer.
  3. To automatically apply the parking brake at high speed
  4. To shut off the engine to conserve fuel

Explanation

ABS prevents wheels from locking under hard braking, ensuring the tires continue to rotate and generate lateral friction so the driver can steer around obstacles while decelerating.

Question 16Priority Signs

What is the three-second rule (regla de los tres segundos) used for in defensive driving?

  1. The time allowed to pass through an intersection on a yellow light
  2. The minimum safe following distance behind the vehicle ahead in dry, normal driving conditions Correct answer.
  3. The duration of turn signal activation before changing lanes
  4. The maximum time a driver may look at the rearview mirror

Explanation

The three-second rule establishes a safe following distance under normal dry conditions by picking a fixed landmark ahead and ensuring at least 3 seconds elapse after the lead vehicle passes it before your vehicle reaches it.

Question 17Priority Signs

What is the mandatory action when an emergency vehicle (police car, fire engine, ambulance) approaches with active sirens and flashing lights?

  1. Maintain your lane and speed so the emergency vehicle can navigate around you
  2. Yield the right-of-way immediately, pulling as far to the right side of the roadway as possible and stopping if necessary Correct answer.
  3. Accelerate to lead the emergency vehicle through the intersection
  4. Pull over to the left median on a two-way street

Explanation

Under Article 142 of Ley 18.290, drivers must immediately yield right-of-way to emergency vehicles operating audible sirens and visual warning lights by pulling over to the right side of the road and stopping until they pass.

Question 18Priority Signs

What does a circular regulatory sign with a red border, white background, and a black arrow pointing right with a diagonal red bar across it mean?

  1. Right turn is mandatory
  2. Right turn is strictly prohibited (Prohibido virar a la derecha) Correct answer.
  3. Road curves to the right ahead
  4. One-way traffic to the right

Explanation

In the Chilean road sign system, circular signs with a red border and a diagonal red slash indicate a prohibition. An arrow crossed by a red diagonal bar prohibits making a turn in that direction.

Question 19Priority Signs

What is the recommended interval for taking rest breaks during long-distance driving according to CONASET?

  1. Every 6 to 8 hours
  2. Every 2 hours or approximately every 200 kilometers, resting for at least 15 to 20 minutes Correct answer.
  3. Only when the fuel tank is completely empty
  4. Only after feeling extreme drowsiness

Explanation

CONASET recommends stopping for at least 15 to 20 minutes every 2 hours of driving or every 200 kilometers to stretch, hydrate, and maintain physical and mental alertness.

Question 20Priority Signs

What is the legal rule regarding overtaking on the right side of another vehicle in Chile?

  1. Overtaking on the right is always permitted on all roads
  2. It is permitted only in three cases: the vehicle ahead is making or about to make a left turn, the urban road has three or more lanes in the same direction, or you are passing cycles travelling in the left-hand lane - and never off the carriageway Correct answer.
  3. Overtaking on the right is allowed whenever you flash your high beams first
  4. Overtaking on the right is legal only on rural single-lane roads

Explanation

Article 120 sets the general rule that overtaking is done on the left. Article 121 then lists the only three situations in which a driver may pass on the right, and adds that the manoeuvre may never be performed off the carriageway, which rules out using the shoulder. The same article gives motorcycles and cycles a narrow extra permission: they may pass stopped vehicles within the same lane on either side, at moderate speed, in order to reach the stop line.

Question 21Priority Signs

What is the meaning of a yellow diamond-shaped sign depicting a curved black arrow?

  1. Mandatory right turn at the next intersection
  2. Warning of an upcoming dangerous curve in the roadway (Señal de advertencia de curva) Correct answer.
  3. Prohibition against turning right
  4. End of a two-way street

Explanation

Yellow diamond-shaped signs are warning signs (señales de advertencia de peligro). An arrow curving to the right warns drivers of an upcoming curve requiring reduced speed and lane discipline.

Question 22Priority Signs

What does a yellow diamond-shaped sign showing two cars with wavy tire tracks behind one car indicate?

  1. Car wash facility ahead
  2. Warning: slippery road surface ahead (Pavimento resbaladizo) Correct answer.
  3. Designated high-speed drifting zone
  4. Narrow bridge crossing ahead

Explanation

This warning sign alerts drivers that the roadway ahead may be slippery due to water, moisture, oil, or road material composition, advising reduced speed and smooth vehicle control.

Question 23Priority Signs

What is the function of orange-colored road signs (señales de color naranja) installed on Chilean roads?

  1. They designate national tourist routes
  2. They are temporary roadwork and construction signs (señalización transitoria) warning of maintenance, detours, or construction crews Correct answer.
  3. They indicate school zones exclusively
  4. They indicate electric vehicle charging points

Explanation

Orange signs are temporary/transitory signs (señalización transitoria) used in work zones to notify drivers of road maintenance, reduced lane widths, flaggers, and detours.

Question 24Priority Signs

What does a green arrow light illuminated simultaneously with a circular red light at a traffic signal mean in Chile?

  1. Drivers must stop and wait for a full green light
  2. Drivers may proceed exclusively in the direction of the green arrow with caution, yielding to pedestrians crossing the crosswalk Correct answer.
  3. The traffic light is defective and should be ignored
  4. All traffic in all directions may proceed

Explanation

Article 104 covers the arrow indications separately from the plain colours. A green arrow means that vehicles may take only the direction the arrow shows; where it is lit together with a red aspect, traffic wanting to go elsewhere stays stopped. The general duty attached to a permissive indication still applies, so the driver entering on the arrow gives way to pedestrians already crossing and enters only with enough room beyond the junction not to block it.

Question 25Priority Signs

Under what condition is turning right on a red light (viraje a la derecha con luz roja) permitted in Chile?

  1. At all intersections if no police officer is present
  2. Only when there is an explicit sign authorizing it ('PERMITIDO VIRAR CON LUZ ROJA'), after coming to a complete stop and yielding to pedestrians and oncoming traffic Correct answer.
  3. Whenever the driver activates emergency hazard flashers
  4. On all one-way streets during nighttime

Explanation

In Chile, right turns on red are strictly prohibited by default. A right turn on red is only legal when a specific regulatory sign explicitly authorizes it ('PERMITIDO VIRAR CON LUZ ROJA'), and even then, the driver must yield completely to crossing pedestrians and through traffic.

Question 26Priority Signs

When approaching a zebra crossing (paso de cebra / paso peatonal) where a pedestrian has stepped onto or is about to step onto the crosswalk, what is the driver's legal duty?

  1. Sound the horn and accelerate to clear the crosswalk before the pedestrian
  2. Yield right-of-way, stopping completely before the stop line to allow the pedestrian to cross safely Correct answer.
  3. Flash high beams to instruct the pedestrian to hurry
  4. Maintain speed because vehicles always have priority over pedestrians on avenues

Explanation

Article 162 sets out the pedestrian rules and, in the same article, the two priorities that bind drivers: a pedestrian who has lawfully begun to cross keeps the right to finish even if the signal changes, and at pedestrian crossings pedestrians have priority over vehicles that are turning. At unregulated pedestrian crossings, pedestrians have priority over vehicles outright. The driver's duty is therefore to stop before the stop line and let them pass.

Question 27Priority Signs

What does a blue rectangular sign with a white 'P' indicate in Chile?

  1. Police station ahead
  2. Permitted parking area (Estacionamiento permitido) Correct answer.
  3. Pedestrian bridge ahead
  4. Mandatory pavement testing zone

Explanation

A blue rectangular sign displaying a white letter 'P' is an informative sign indicating an authorized vehicle parking area or zone.

Question 28Priority Signs

A prohibition sign shows a red cross over the disc. What does the Chilean sign 'PROHIBIDO ESTACIONAR Y DETENERSE' mean?

  1. Parking is allowed for up to 15 minutes
  2. Neither parking nor stopping is permitted on that stretch, so you may not even halt briefly to set down a passenger Correct answer.
  3. Hospital zone ahead
  4. Level railway crossing

Explanation

The Chilean sign catalogue carries two related prohibitions. 'PROHIBIDO ESTACIONAR' bans leaving the vehicle parked; 'PROHIBIDO ESTACIONAR Y DETENERSE' is the stricter one and bans halting at all, so a driver may not pull up even momentarily to drop someone off. The distinction matters because the Ley de Tránsito treats detención and estacionamiento as different acts: stopping to take on or set down passengers is otherwise allowed where parking is not.

Question 29Priority Signs

What is the practical difference between the Chilean signs 'PROHIBIDO ESTACIONAR' and 'PROHIBIDO ESTACIONAR Y DETENERSE'?

  1. There is none; the two names refer to the same sign
  2. The first bans leaving the vehicle parked but still allows a brief halt to pick up or set down passengers; the second bans halting altogether Correct answer.
  3. The first applies only at night and the second only by day
  4. The first applies to cars and the second only to lorries

Explanation

Chilean law separates the two acts. Detención is a short halt for the minimum time needed to take on or set down passengers; estacionamiento is leaving the vehicle standing for longer than that. 'PROHIBIDO ESTACIONAR' removes only the second, so a momentary halt remains possible. 'PROHIBIDO ESTACIONAR Y DETENERSE' removes both, which is why it is used where a stopped vehicle would obstruct or endanger traffic.

Question 30Priority Signs

What is the 'Cruz de San Andrés' (St. Andrew's Cross) sign at a railway crossing?

  1. A medical first aid station sign
  2. A regulatory crossbuck sign positioned directly at a railway crossing indicating the exact point of the rail line and the number of tracks Correct answer.
  3. A pedestrian hiking trail marker
  4. An ecclesiastical landmark sign

Explanation

The Cruz de San Andrés is an X-shaped regulatory sign positioned immediately adjacent to railroad tracks that warns drivers of the track location, mandating yielding priority to all rail vehicles.

Question 31Priority Signs

Under what condition is sounding the vehicle horn (bocina / claxon) permitted in urban areas in Chile?

  1. To greet acquaintances or express frustration in traffic jams
  2. Exclusively to prevent an imminent traffic collision or accident Correct answer.
  3. To alert pedestrians to clear the road faster at intersections
  4. Whenever a traffic light turns green and the front car does not move immediately

Explanation

Article 74 prohibits the use of any sound device fitted to a vehicle in urban areas. It allows use on rural roads only where necessary, and it preserves one narrow exception for everyone: the horn may be used to prevent an accident, and only where its use is strictly necessary. Emergency vehicles on an urgent call are exempt. The same article forbids sounding the horn inside a tunnel or on entering or leaving one.

Question 32Priority Signs

What does a yellow diamond sign with a pedestrian silhouette walking between two parallel lines indicate?

  1. School playground zone
  2. Upcoming pedestrian crossing (Zona de peatones / Próximo paso peatonal) Correct answer.
  3. Jogging trail along the highway
  4. Footwear store location

Explanation

This warning sign alerts drivers that they are approaching a designated pedestrian crossing (paso de cebra), requiring them to reduce speed and prepare to yield.

Question 33Priority Signs

How should a driver execute a safe left turn (viraje a la izquierda) from a two-way street onto another two-way street?

  1. Cut across the oncoming lane as early as possible
  2. Approach the center line without crossing it, signal at least 30 m in advance, yield to oncoming traffic, and enter the intersecting street on the right-hand side of its axis Correct answer.
  3. Turn from the extreme right-hand curb across all lanes
  4. Sound the horn and accelerate through oncoming traffic

Explanation

Under Article 138 of Ley 18.290, turning left requires positioning near the center line, signaling at least 30 meters ahead, yielding priority to all oncoming traffic and pedestrians, and completing the turn into the right lane of the cross street without cutting corners.

Question 34Priority Signs

What is the meaning of a yellow curb marking (solera pintada de amarillo) along the street edge in Chile?

  1. Exclusive taxi parking area
  2. Parking is strictly prohibited along that curb section (Prohibición de estacionar) Correct answer.
  3. Loading zone permitted for 2 hours
  4. Bus stop for long-distance coaches

Explanation

Under the Chilean road marking manual, a yellow painted curb (solera amarilla) indicates a continuous parking prohibition along that curb section.

Question 35Priority Signs

What is the yellow grid box (caja amarilla / cruce antibloqueo) painted at busy intersections in Chile?

  1. A designated parking area for breakdown vehicles
  2. An anti-gridlock marking: drivers must not enter the yellow grid box unless there is sufficient space on the exit side to clear the intersection completely Correct answer.
  3. A pedestrian gathering zone during earthquakes
  4. An acceleration lane for motorcycles

Explanation

The yellow grid box (cruce antibloqueo) prohibits drivers from entering the intersection if traffic congestion ahead prevents them from clearing it, ensuring the cross-street is not blocked when the light changes.

Question 36Priority Signs

What is the meaning of a circular blue regulatory sign showing a white bicycle silhouette?

  1. Bicycles prohibited
  2. Mandatory bicycle path or lane (Ciclovía obligatoria) Correct answer.
  3. Bicycle repair shop ahead
  4. Bicycle race in progress

Explanation

Blue circular signs indicate mandatory instructions (señales de obligación). A bicycle icon on a blue disc designates an exclusive, mandatory cycleway (ciclovía).

Question 37Priority Signs

What is the 'Dutch Reach' (maniobra holandesa) technique recommended by road safety authorities for exiting a parked vehicle?

  1. Kicking the door open forcefully
  2. Opening the car door with the hand furthest from the door (right hand for driver), forcing the body and head to turn to look back for approaching cyclists and motorcyclists Correct answer.
  3. Exiting through the passenger side window
  4. Opening the door while the car is still moving

Explanation

Opening the door with the far hand (right hand for the driver) naturally rotates the driver's torso and head toward the blind spot, preventing 'dooring' collisions with oncoming cyclists or scooters.

Question 38Priority Signs

Under what circumstance may a driver use hazard warning flashers (luces de advertencia de peligro / luces de emergencia) while driving in Chile?

  1. To park illegally on a red-painted curb or bus stop
  2. When the vehicle is disabled, stopped due to emergency, or when suddenly forced to slow down dramatically to warn trailing vehicles of a major obstruction ahead Correct answer.
  3. To signal a left turn when turn indicators are broken
  4. To drive faster through urban traffic jams

Explanation

Hazard flashers (simultaneous flashing of all four turn signals) are reserved strictly for vehicle breakdown, road emergencies, or suddenly warning trailing traffic of a major hazard ahead. Using them to park illegally is prohibited.

Question 39Priority Signs

What is the primary danger when driving through deep standing water (inundaciones / vados de agua)?

  1. Water entering the air intake can cause hydraulic lock (hidrobloqueo), instantly destroying internal engine pistons and connecting rods, and wet brake pads lose friction temporarily Correct answer.
  2. Tire rubber dissolves in water
  3. The car's FM radio stops working permanently
  4. Water turns gasoline into diesel fuel

Explanation

If water is sucked into the engine intake, cylinders attempt to compress incompressible liquid, snapping connecting rods and destroying the block (hydrolock). Furthermore, wet brakes suffer immediate friction loss until dried by gentle tapping.

Question 40Priority Signs

What does a yellow diamond warning sign showing arrows circulating around a central island mean?

  1. Motorway toll plaza ahead
  2. A roundabout is approaching (Próxima rotonda) Correct answer.
  3. Dead-end street ahead
  4. Airport runway crossing

Explanation

It is a warning sign announcing a roundabout ahead. Warning signs of this shape and colour flag a hazard or an unexpected situation so the driver can adapt in advance: here, slow down, decide the exit you need early enough to enter in the correct lane, and be ready to give way to the traffic already circulating.

Question 41Priority Signs

What does a rectangular green informative sign with white text and route numbers on a Chilean highway indicate?

  1. Commercial advertising billboard
  2. Directional guide signage (Señales de orientación y destino) providing distance to destinations, highway numbers, and upcoming exits Correct answer.
  3. Mandatory stop sign
  4. Speed limit penalty notice

Explanation

Green rectangular signs on highways and expressways are directional guide and route identification signs (señales de información de destino y ruta) providing advance destination and exit information.

Question 42Priority Signs

When is reversing (marcha atrás) permitted on a public road in Chile?

  1. Whenever you have missed a motorway exit
  2. Only where the manoeuvre is indispensable to keep traffic flowing, to join the traffic stream or to park - and never at an intersection unless a Carabinero expressly directs it Correct answer.
  3. For unlimited distances on one-way streets
  4. Through intersections whenever the light is green

Explanation

Article 115 allows reversing only where it is indispensable to maintain free circulation, to join the traffic stream, or to park the vehicle. It then adds a flat prohibition of its own: a vehicle may not be reversed at an intersection even if it has already crossed the stop line, unless a Carabinero expressly indicates otherwise. The CONASET manual repeats the same short list of permitted cases.

Question 43Hazards Fitness

Under Article 111 of the Chilean Ley de Tránsito, which blood alcohol range corresponds to driving 'bajo la influencia del alcohol'?

  1. Any measurable amount above 0.0 g/l
  2. More than 0.3 g/l and less than 0.8 g/l Correct answer.
  3. 0.8 g/l or more
  4. More than 1.2 g/l

Explanation

Article 111 states the two bands precisely: driving is 'bajo la influencia del alcohol' when the alcoholemia report or breath test yields more than 0.3 and less than 0.8 grams per litre of blood alcohol, and 'en estado de ebriedad' at 0.8 g/l or above. Ley 20.580, popularly called Ley Tolerancia Cero, is the 2012 reform that lowered these figures. A reading of 0.3 g/l or below is expressly excluded by Article 109 from counting as a deficient physical condition.

Question 44Hazards Fitness

What is the legal blood alcohol threshold that defines driving 'en estado de ebriedad' (in a state of drunkenness) under Chilean law?

  1. 0.50 grams per liter (g/l)
  2. 0.60 grams per liter (g/l)
  3. 0.80 grams per liter (g/l) or higher Correct answer.
  4. 1.00 grams per liter (g/l)

Explanation

Under Ley 18.290 (amended by Ley 20.580 and Ley 20.770 / Ley Emilia), a blood alcohol concentration of 0.80 g/l or greater legally constitutes driving 'en estado de ebriedad', punishable with criminal conviction, license suspension or cancellation, and imprisonment.

Question 45Hazards Fitness

Using the CONASET rule of thumb, what is the approximate reaction distance (distancia de reacción) of a vehicle travelling at 110 km/h?

  1. 11 metres
  2. 22 metres
  3. 33 metres Correct answer.
  4. 55 metres

Explanation

The Libro para la Conducción en Chile estimates reaction distance by multiplying the first figure of the speed by three, based on a normal reaction time of about one second. That shortcut works up to 99 km/h; from 100 km/h upwards the manual says to take the first two digits. At 110 km/h that gives 11 × 3 = 33 metres travelled before the driver even begins to brake, and the braking distance is then added on top to obtain the total stopping distance.

Question 46Hazards Fitness

What is 'aquaplaning' (or hidroplaneo) and what is the proper action if your vehicle experiences it?

  1. Tires grip the road better in heavy rain; accelerate to push through the water
  2. Tires lose contact with the road surface by riding on a film of water; gently ease off the accelerator without braking abruptly or making sharp steering movements Correct answer.
  3. The car's cooling system overheats; pull over immediately and turn off the engine
  4. The brake pads dry out; pump the brake pedal vigorously and turn the wheel sharply

Explanation

Hydroplaning occurs when water builds up in front of the tires faster than tread grooves can evacuate it, lifting the tire off the pavement. The driver must smoothly release the accelerator, keep the steering wheel steady, and avoid slamming the brakes until tires regain road contact.

Question 47Hazards Fitness

Why is the beginning of a rainfall (the first few drops) especially hazardous for driving?

  1. Raindrops obscure street signs completely
  2. Water mixes with accumulated dust, oil, and grease on the asphalt, creating a highly slippery soap-like film Correct answer.
  3. Tire air pressure drops instantly by 50%
  4. Brake fluid boils inside the master cylinder

Explanation

When light rain begins, water mixes with road grime, petroleum residues, and rubber particles that have accumulated on the road surface, forming an emulsion with very low friction before heavy rain washes it away.

Question 48Hazards Fitness

Under what conditions must the following distance behind the lead vehicle be increased to at least 4 to 6 seconds?

  1. When driving on a sunny day on a straight highway
  2. When driving in rain, fog, snow, on gravel roads, or when following heavy commercial vehicles and motorcycles Correct answer.
  3. Only when driving inside urban city centers
  4. When driving a newly purchased vehicle

Explanation

Adverse weather (rain, fog, ice), reduced visibility, loose road surfaces (gravel), or following large vehicles that block forward sightlines require doubling or tripling following distance to at least 4–6 seconds.

Question 49Hazards Fitness

What is the main physiological effect of alcohol consumption on a driver's visual perception?

  1. It improves peripheral vision and reaction time
  2. It narrows peripheral vision (tunnel vision / visión de túnel), degrades depth perception, and impairs night vision recovery after glare Correct answer.
  3. It enhances night vision acuity by dilating pupils
  4. It has no measurable effect on vision if BAC is under 0.80 g/l

Explanation

Alcohol induces 'tunnel vision' by narrowing peripheral awareness, degrades stereoscopic depth perception (judging distances and speeds), and slows the pupillary reflex when recovering from oncoming headlight glare.

Question 50Hazards Fitness

How does driver fatigue (fatiga) affect reaction time and decision-making on long highway trips?

  1. It sharpens focus and shortens reaction time
  2. It lengthens reaction time, increases the risk of micro-sleeps (microsueños), and impairs hazard judgment Correct answer.
  3. It only causes physical muscle soreness without affecting cognitive processing
  4. It can be completely eliminated by opening the window or turning up the radio

Explanation

Driver fatigue significantly delays reaction times, induces involuntary micro-sleep episodes lasting 2–5 seconds during which the vehicle travels uncontrolled, and severely degrades hazard perception.
