    The GPS navigator must be programmed...

    • ADeteniéndonos donde sea necesario.stopping wherever necessary.
    • BCuando necesitemos ayuda vía satélite.when we need satellite help.
    • CAntes de iniciar el viaje.before starting the journey.

    ¿Qué percibe el conductor con el efecto túnel?

    What does the driver perceive with tunnel vision?

    • AUna pérdida de la sensación de la velocidad.A loss of the sense of speed.
    • BPercibe como la fatiga disminuye.They feel their tiredness decreasing.
    • CSólo percibe el centro de la calzada y deja de ver los laterales.They only perceive the centre of the carriageway and stop seeing the sides.
    Explanation

    With tunnel vision, caused mainly by high speed, the field of vision narrows: the driver only clearly perceives the centre of the carriageway and stops seeing what is happening at the sides, such as vehicles or pedestrians approaching from one side.

  4. Nº 304

    ¿Cuál es la tasa máxima de alcohol en el aire espirado permitida para un conductor novato?

    What is the maximum breath alcohol level allowed for a novice driver?

    • A0,30 miligramos por litro durante los dos primeros años.0.30 milligrams per litre during the first two years.
    • B0,25 miligramos por litro durante el primer año.0.25 milligrams per litre during the first year.
    • C0,15 miligramos por litro durante los dos primeros años.0.15 milligrams per litre during the first two years.
    Explanation

    The correct maximum breath alcohol level allowed for a novice driver is 0.15 milligrams per litre during the first two years after obtaining the driving licence. This is set out in Article 20 of the General Traffic Regulations, which states that novice drivers must respect this stricter limit to ensure road safety, because their lack of experience can make them more likely to make wrong decisions under the influence of alcohol.

    ¿Qué debe hacer un conductor con sueño?

    What should a sleepy driver do?

    • ABeber algo refrescante.Have a refreshing drink.
    • BDescansar lo antes posible en un lugar adecuado.Rest as soon as possible in a suitable place.
    • CSeguir conduciendo y descansar solo después de 2 horas o 200 kilómetros.Keep driving and rest only after 2 hours or 200 kilometres.
    Explanation

    Drowsiness reduces attention, increases reaction time and can cause microsleeps. At the first symptoms you must stop in a safe place and rest; having a refreshing drink or opening the window only helps for a few minutes. A break every 2 hours or 200 km is a preventive measure, not a deadline to hold out until.

  17. Nº 317

    Question picture

    La depresión puede provocar en la conducción…

    When driving, depression can cause...

    • AMás capacidad de reacción.a greater ability to react.
    • BUn aumento de las distracciones.more distractions.
    • CUna percepción más eficiente.more efficient perception.
    Explanation

    The possible effects of depression on the driver of a vehicle include more distractions at the wheel, a lower ability to react, an incorrect perception of their surroundings and more insecurity, which leads them to make wrong decisions. In any case, a driver affected by depression should consult a specialist before getting behind the wheel.

  18. Nº 318

    Negarse a la prueba de alcoholemia es:

    Refusing to take an alcohol test is:

    • AUna falta levea minor offence.
    • BUn delitoa crime.
    • CNo tiene consecuenciaswithout consequences.
    Explanation

    Refusing to take an alcohol test is a crime of disobedience, punishable by 6 months to 1 year in prison and loss of the licence for 1 to 4 years.

  19. Nº 319

    ¿Cómo afectan el sueño y la fatiga a la conducción?

    How do sleepiness and fatigue affect driving?

    • AAumentan la distancia de reacción.They increase the reaction distance.
    • BDisminuyen el tiempo de reacción.They reduce reaction time.
    • CAumentan la capacidad de reacción.They increase the ability to react.
    Explanation

    Sleepiness and fatigue harm the driver's physical and mental abilities. Fatigue can increase the reaction distance, because the driver may take longer to perceive a danger and react properly. This is supported by the Traffic and Road Safety Code, which mentions the role of fatigue in crashes and the need to prevent its effects at the wheel. So the correct answer is that sleepiness and fatigue increase the reaction distance, making it harder for the driver to respond quickly and effectively to dangerous situations.

  20. Nº 320

    Hace un año obtuvo el permiso A2 y ahora obtiene el permiso B. ¿Cuál será la tasa máxima de alcohol permitida?

    You got your A2 licence a year ago and now you get your B licence. What will your maximum alcohol level be?

    • A0,3 gramos por litro de sangre durante dos años.0.3 grams per litre of blood for two years.
    • BUna tasa que no supere los 0,5 gramos por litro de sangre.A level of no more than 0.5 grams per litre of blood.
    • C0,3 gramos por litro de sangre durante un año.0.3 grams per litre of blood for one year.
    Explanation

    The 0.3 grams per litre of blood limit applies for the two years after getting your first licence, not after each new licence. Since you got the A2 a year ago, when you get the B you only have one more year at that limit; after that, the general limit of 0.5 g/l applies.

  21. Nº 321

    ¿Cuál es la tasa máxima de alcoholemia en aire para un conductor novel?

    What is the maximum breath alcohol level for a novice driver?

    All drivers of vehicles, during the two years after obtaining their first driving licence or permit, are prohibited from driving with alcohol levels above: in blood, 0.3 grams per litre (g/l); in breath, 0.15 milligrams per litre (mg/l).

  22. Nº 322

    Question picture

    El tiempo de reacción puede aumentar...

    Reaction time can increase...

    • Adespués de una comida ligera.after a light meal.
    • Bsi usamos gafas graduadas.if we wear prescription glasses.
    • Cdespués de una fuerte discusión.after a heated argument.
    Explanation

    Intense emotional states, such as anger after an argument, distract your attention and slow down your response to something unexpected, so they increase reaction time. Neither a light meal nor wearing prescription glasses makes it worse.

  23. Nº 323

    ¿Cuál es la tasa máxima de alcoholemia como norma general?

    What is the maximum alcohol level as a general rule?

    • A0,25 miligramos de alcohol por litro de aire.0.25 milligrams of alcohol per litre of air.

    Accidents caused by sleepiness happen...

    • Aúnicamente cuando el conductor se queda totalmente dormido.only when the driver falls completely asleep.
    • Bsiempre por la noche.always at night.
    • Ctambién antes de que el conductor se quede totalmente dormido.also before the driver falls completely asleep.
    Explanation

    Many sleep-related accidents happen before the driver is fully asleep, because of microsleeps or drowsiness, which reduces attention and makes reaction time longer. They can happen at any time, not only at night.

  25. Nº 325

    Respecto al llamado "efecto túnel", producido al circular con una velocidad elevada:

    Regarding the so-called 'tunnel effect' caused by driving at high speed:

    • ASe trata de un fenómeno positivo, puesto que permite ver mejor los posibles peligros de la vía.It is a positive phenomenon, because it lets you see possible dangers on the road better.
    • BImpide ver adecuadamente cualquier peligro en los laterales de la carretera.It stops you from seeing any danger at the sides of the road properly.
    • CMejora la capacidad de anticipación a los eventos del tráfico.It improves your ability to anticipate traffic events.
    Explanation

    The tunnel effect stops you from seeing any danger at the sides of the road properly, because when driving at high speed our field of vision narrows and we can only see the central part of the road clearly. The sides are almost not seen, or are seen very blurred. This increases the risk of not noticing traffic signs, other vehicles or pedestrians, putting our safety and that of others at risk.

  26. Nº 326

    Las distracciones pueden originarse...

    Distractions can be caused...

    • Asolo por elementos dentro del vehículo.only by things inside the vehicle.
    • Bpor elementos externos e internos del vehículo.by things outside and inside the vehicle.
    • Csolo por elementos fuera del vehículo.only by things outside the vehicle.
    Explanation

    The correct answer is the option about things outside and inside the vehicle, because distractions while driving can be caused both by things inside the vehicle, such as using navigation devices or music players, and by things outside, including other vehicles, pedestrians or traffic signs. According to the Spanish Highway Code, distractions are a significant risk factor for road safety, and it is essential to stay alert to both types to avoid accidents.

  27. Nº 327

    La alcoholemia hará que los deslumbramientos durante la conducción...

    Having alcohol in your blood will make glare while driving...

    • AAumenten.increase.
    • BDisminuyan.decrease.
    • CNo afecta.It has no effect.
    Explanation

    The effects of alcohol on driving include judging distances and speed less well, experiencing the tunnel effect and being more sensitive to glare.

  28. Nº 328

    Question picture

    Mirar un cartel publicitario situado en el entorno de la vía, ¿puede distraer al conductor de un vehículo?

    Can looking at an advertising board by the road distract the driver of a vehicle?

    • ASolo si se circula de noche y el cartel está iluminado.Only if you are driving at night and the board is lit.
    • BNo.No.
    • CSí.Yes.
    Explanation

    Looking at an advertising board by the road can distract the driver of a vehicle because it takes their attention away from the road. When the driver looks at a board, even for a moment, they may lose concentration on driving, which increases the risk of accidents. This applies at any time of day, not only at night or when the board is lit.

  29. Nº 329

    Question picture

    Para evitar el cansancio al conducir, ¿cada cuánto tiempo debes descansar?

    To avoid tiredness when driving, how often should you rest?

    • ACada 2 horas o cada 200 kilómetros.Every 2 hours or every 200 kilometres.
    • BSiempre que hay un área de descanso.Whenever there is a rest area.
    • CCada 3 horas o cada 400 kilómetros.Every 3 hours or every 400 kilometres.
    Explanation

    It is recommended to stop and rest at least every two hours or every 200 kilometres, even if you do not feel tired, because fatigue builds up gradually and reduces attention and reflexes. Waiting for a rest area to appear can make your time at the wheel too long.

  30. Nº 330

    Question picture

    Si circulando le sorprende el sueño debe:

    If sleepiness catches you by surprise while driving, you should:

    • AAumentar la velocidad para tratar de llegar cuanto antes a su destino.increase speed to try to reach your destination as soon as possible.
    • BEstacionar el vehículo en lugar permitido y dormir.park the vehicle in a permitted place and sleep.
    • CReducir la velocidad y circular por el arcén.reduce speed and drive on the hard shoulder.
    Explanation

    The most important rules to avoid an accident caused by sleepiness or fatigue are: if we feel tired or sleepy while driving, the best thing is to stop and rest in a suitable place and sleep for about 20 or 30 minutes; rest for 20 to 30 minutes every 2 hours or every 200 kilometres at most; always watch for the signs and symptoms of sleepiness or fatigue.

  31. Nº 331

    Question picture

    ¿Es aconsejable conducir un turismo calzado con unas chanclas?

    Is it advisable to drive a car wearing flip-flops?

    • ASí, porque al no sujetar el pie, es más fácil ejercer la presión correcta sobre los pedales.Yes, because they do not hold the foot, so it is easier to put the right pressure on the pedals.
    • BSí, porque permiten un manejo más rápido y seguro de los pedales.Yes, because they allow faster and safer use of the pedals.
    • CNo, porque podrían caerse y dificultar el manejo de los pedales.No, because they could come off and make it hard to use the pedals.
    Explanation

    Driving a car in flip-flops is not advisable because they can slip or come off, which makes it hard to control the pedals properly. This increases the risk of accidents because the driver cannot use the brake, accelerator and clutch pedals precisely and safely. The regulations state that you must be able to control the vehicle at all times, and if your footwear prevents this, you could be fined.

  32. Nº 332

    Question picture

    Si el estado psicofísico del conductor no es el apropiado, el tiempo de reacción…

    If the driver's physical and mental state is not right, reaction time...

    • Aaumenta.increases.
    • Bdisminuye.decreases.
    • Cno varía.does not change.
    Explanation

    Reaction time is the time that passes from when the driver sees an obstacle until they react. This time varies depending on the driver's physical and mental state, never because of the speed or the condition of the road. Although it may seem that the reaction to an obstacle or an unexpected situation should be instant, a driver's average reaction time is about 0.75 seconds.

  33. Nº 333

    Negarse a someterse a las pruebas de detección de alcohol o drogas:

    Refusing to take alcohol or drug tests:

    • ANo tiene consecuencias si el conductor lo pide por escrito.has no consequences if the driver asks for it in writing.
    • BEs constitutivo de delito contra la seguridad vial.is a crime against road safety.
    • CSolo es una infracción leve.is only a minor offence.
    Explanation

    Refusing the tests is a crime against road safety set out in the Criminal Code (Article 383).

  34. Nº 334

    ¿Comer o beber agua reduce el nivel de alcohol en la sangre?

    Does eating or drinking water reduce the level of alcohol in the blood?

    • ASí, mientras se bebe alcohol.Yes, while drinking alcohol.
    • BSí, después de beber alcohol.Yes, after drinking alcohol.
    • CNo, solo retrasa la absorción del alcohol.No, it only delays the absorption of alcohol.
    Explanation

    Eating or drinking water does not remove alcohol from the blood: it only delays its absorption, so the level rises more slowly but can reach the same point. Alcohol is eliminated slowly by the liver, and the limits in Article 20 of the RGC are measured in blood or in exhaled air.

  35. Nº 335

    Question picture

    Si se lleva instalado un navegador GPS hay que tener en cuenta que...

    If you have a GPS navigator installed, you should bear in mind that...

    • Amientras se conduce no es conveniente apartar la vista del navegador.while driving, you should not take your eyes off the navigator.
    • Blas indicaciones del navegador prevalecen sobre la señalización de la vía.the navigator's instructions prevail over the road signs.
    • Cel criterio del conductor debe prevalecer sobre las indicaciones del navegador.the driver's judgement must prevail over the navigator's instructions.
    Explanation

    The navigator is only an aid: its instructions may be out of date or may not match the real situation, so the driver's judgement and the road signs always prevail.

  36. Nº 336

    ¿Qué teléfonos se pueden usar mientras se conduce?

    Which phones may be used while driving?

    • ASistemas de manos libres.Hands-free systems.
    • BSistemas con auriculares.Systems with earphones.
    • CTodos los sistemas están permitidos.All systems are allowed.
    Explanation

    Article 18.2 of the General Traffic Regulations prohibits using a mobile phone while driving. It is only allowed when the call is made without using your hands and without earphones, a headset or similar devices, such as a hands-free system built into the vehicle.

  37. Nº 337

    Question picture

    El mal estado de la vía, ¿influye en las aptitudes psicofísicas del conductor?

    Does a road in poor condition affect the driver's physical and mental abilities?

    • ASí.Yes.
    • BSolo en conductores noveles.Only in novice drivers.
    • CNo.No.
    Explanation

    A road in poor condition is one of several external factors that contribute to fatigue, because it makes driving harder and more uncomfortable, causing greater tiredness.

    Question picture

    ¿Se producen accidentes debidos al sueño, durante el día?

    Do accidents caused by sleepiness happen during the day?

    • ASi, especialmente a primeras horas de la tarde.Yes, especially in the early afternoon.
    • BNo, estos solo se producen de noche.No, they only happen at night.
    • CSi, pero solo, si no se ha dormido bien la noche anterior.Yes, but only if you did not sleep well the night before.
    Explanation

    To have an accident caused by sleepiness, you do not need to fall asleep, because the risks of drowsiness appear much earlier. In addition, these accidents do not only happen at night, because many circumstances cause sleepiness during the day.

  39. Nº 339

    El estrés hace que el conductor...

    Stress makes the driver...

    • Asea más hostil con los demás usuarios.more hostile towards other road users.
    • Brespete más la señalización.respect road signs more.
    • Casuma menos riesgos.take fewer risks.
    Explanation

    Stress can seriously impair our ability to drive safely and can increase aggression, hostility and competitiveness towards other drivers.

  40. Nº 340

    Conduciendo bajo los efectos del sueño...

    When driving while sleepy...

    • AAumenta el tiempo de reacción.reaction time increases.
    • BDisminuye el tiempo de reacción.reaction time decreases.
    • CAumenta la capacidad de reacción.the ability to react increases.
    Explanation

    Sleepiness makes the driver react more slowly: it reduces their ability to react and increases the time they take to react.

  41. Nº 341

    La tasa máxima general de alcohol en aire espirado para un conductor con más de dos años de permiso es de:

    The general maximum breath alcohol level for a driver who has held a licence for more than two years is:

    • B0,15 mg/l.0.15 mg/l.
    • C0,30 mg/l.0.30 mg/l.
    Explanation

    The correct figure is 0.25 mg/l of exhaled air; 0.15 is for novice and professional drivers, and 0.30 is not a legal limit for breath.

  42. Nº 342

    Question picture

    ¿Puedes utilizar el teléfono móvil cuando estás parado delante de un stop?

    Can you use your mobile phone when you are stopped at a stop sign?

    • ANo.No.
    • BSolo con un sistema de manos libres y sin usar cascos o auriculares.Only with a hands-free system and without using a headset or earphones.
    • CSí, porque el vehículo está parado.Yes, because the vehicle is stopped.
    Explanation

    When you are stopped at a stop sign you are still driving, so the ban on using a mobile phone applies (Article 18 of the General Traffic Regulations). You may only communicate without using your hands and without a headset or earphones, that is, with a hands-free system. The fact that the vehicle is stopped for a moment does not change anything.

A driver who does not perceive their surroundings properly is a danger to themselves and to others.
