Durante un viaje con su turismo con remolque, su conductor se encuentra muy fatigado, ¿qué debe hacer?
During a journey in your car with a trailer, the driver feels very tired. What should they do?
- AAumentar la velocidad para acabar el viaje cuanto antes.Increase speed to finish the journey as soon as possible.
- BTomar alguna bebida alcohólica como estimulante.Have an alcoholic drink as a stimulant.
- CBuscar un lugar adecuado y descansar.Find a suitable place and rest.
ExplanationThe correct answer is to find a suitable place and rest, because to fight fatigue it is important to rest properly before starting the journey and, if fatigue appears while driving, it is advisable to park the vehicle and take a short walk to get some fresh air. You must never drink alcohol to stimulate yourself as a driver. Resting is the best option to recover your energy and continue the journey safely.
¿Cuál es la tasa de alcohol permitida a un ciclista?
What alcohol level is allowed for a cyclist?
- A0,25 miligramos por litro de aire expirado.0.25 milligrams per litre of exhaled air.
- B0,15 miligramos por litro de aire expirado.0.15 milligrams per litre of exhaled air.
- C0,3 gramos por litro en sangre.0.3 grams per litre of blood.
ExplanationThe general alcohol level applies to cyclists: 0.25 milligrams per litre of exhaled air, or 0.5 grams per litre of blood. The reduced levels of 0.15 mg or 0.3 g are for novice and professional drivers.

En general, un conductor con sueño...
In general, a sleepy driver...
- Aacepta un mayor nivel de riesgo en la conducción.accepts a higher level of risk when driving.
- Bacepta un menor nivel de riesgo en la conducción.accepts a lower level of risk when driving.
- Ctarda menos en reaccionar ante un suceso imprevisto.takes less time to react to an unexpected event.
ExplanationSleepiness reduces the perception of danger and self-criticism: a sleepy driver accepts more risk, reacts later and may have microsleeps lasting several seconds.

Debe buscar la ruta en el navegador GPS...
You should look up the route on the GPS navigator...
- ADeteniéndose dónde sea necesario.stopping wherever necessary.
- BCuando el navegador lo lleva por una zona desconocida.when the navigator takes you through an unfamiliar area.
- CAntes de iniciar la marcha.before setting off.
ExplanationTo look up and program the route safely on our GPS navigator, this must always be done before setting off. If we need to change the search once the car is moving, we will find a safe place where stopping or parking is allowed, and we should only operate the GPS when the car is stationary.
Respecto a las drogas, ¿qué establece la normativa para conducir?
What do the rules say about drugs and driving?
- ASe permite un mínimo si no afecta a la conducción.A minimum amount is allowed if it does not affect driving.
- BEstá prohibido conducir con presencia de drogas en el organismo, con tasa cero.It is prohibited to drive with drugs present in the body; the limit is zero.
- CSolo se sanciona si se detecta a más de 0,25 mg/l.It is only penalised if more than 0.25 mg/l is detected.
ExplanationFor drugs, a zero limit applies: it is prohibited to drive with drugs present in the body, except for those taken on medical prescription that do not reduce the ability to drive.

¿Qué síntomas me avisan de que estoy fatigado?
Which symptoms warn me that I am tired?
- AEl parpadeo constante y la pesadez de los ojos.Constant blinking and heavy eyes.
- BNo hacer movimientos en el asiento, ni cambios de postura.Not moving in the seat or changing position.
- CLa sensación de euforia.A feeling of euphoria.
ExplanationThe driver of a vehicle will start to notice that they are tired when any of the following symptoms appear while driving: constant shifting in the seat, yawning, stretching the arms, constant blinking and heavy eyes. When this happens, they should look for a place where they can park and stop to rest.
¿Qué efectos produce el éxtasis?
What effects does ecstasy have?
- AMayor facilidad de mantener la concentración en el tráfico.It is easier to stay focused on the traffic.
- BDisminución del tiempo de reacción.A shorter reaction time.
- CSe pueden sufrir ilusiones ópticas.You may have optical illusions.
ExplanationEcstasy can cause optical illusions, which can lead to dangerous evasive manoeuvres.
Un resfriado común, puede producir...
A common cold can cause...
- Asomnolencia y falta de concentración.sleepiness and lack of concentration.
- Bsomnolencia y falta de coordinación.sleepiness and lack of coordination.
- Cdéficits cognitivos graves.serious cognitive deficits.
ExplanationRespiratory illnesses, including flu or the common cold, can make the driver lose attention and concentration and feel sleepy.

El navegador GPS, ¿puede ser peligroso para la conducción?
Can the GPS navigator be dangerous for driving?
- ASí, cuando produce distracciones.Yes, when it causes distractions.
- BSí, cuando nos lleva por una ruta distinta a la habitual.Yes, when it takes us on a different route from the usual one.
- CNo, es de gran ayuda a la conducción.No, it is a great help for driving.
ExplanationOne of the most common causes of distraction at the wheel is using navigation systems or GPS. Drivers must be able to control their vehicles at all times. If we operate the GPS while driving, we are not meeting this very important obligation and it is easy to have an accident. To stop the GPS becoming a distraction, we should: plan the journey before starting it (do not operate it while moving); listen to the voice instructions (avoid looking at the screen); let the driver's judgement prevail at all times. Although the navigator can help us control our speed, the main source of information must be the speedometer.

¿Cuál será la tasa máxima de alcohol permitida para los conductores noveles?
What is the maximum alcohol level allowed for novice drivers?
- A0.25 mg/l en aire expirado o 0.5 g/l en sangre.0.25 mg/l in exhaled air or 0.5 g/l in blood.
- B0.15 mg/l en aire expirado o 0.30 g/l en sangre.0.15 mg/l in exhaled air or 0.30 g/l in blood.
- C0.30 mg/l en aire expirado o 0.6 g/l en sangre.0.30 mg/l in exhaled air or 0.6 g/l in blood.
ExplanationNovice drivers, during the first two years of holding a licence, must not exceed 0.15 mg of alcohol per litre of exhaled air or 0.30 g per litre of blood. The limits of 0.25 mg/l and 0.5 g/l are the general ones for all other drivers.

El estrés produce en el conductor...
Stress causes the driver to show...
- Auna mayor agresividad y un comportamiento imprudente al volante.more aggression and reckless behaviour at the wheel.
- Buna mayor rapidez en la toma de decisiones.faster decision-making.
- Cuna disminución de la fatiga.less fatigue.
ExplanationStress can seriously impair our ability to drive safely by increasing aggression, hostility and competitiveness towards other drivers. Behaviour can become more reckless and higher levels of risk are accepted at the wheel, so driving becomes more dangerous. Distractions and fatigue increase.

Conducir con mal tiempo, ¿puede favorecer la fatiga?
Can driving in bad weather make fatigue more likely?
- ASí, por ello se debe descansar con mayor frecuencia.Yes, so you should rest more often.
- BNo.No.
- CSólo en los viajes largos.Only on long journeys.
ExplanationDriving in rain, fog or wind requires constant extra attention and muscle tension, which tires the driver sooner; that is why you should rest more often.
El campo visual de los niños es…
Children's field of vision is...
- AIgual que el de los adultos.the same as adults'.
- BMenor que el de los adultos.narrower than adults'.
- CMayor que el de los adultos.wider than adults'.
ExplanationChildren's field of vision is narrower than adults', especially at the sides, and because they are short they cannot see over cars. That is why they notice approaching vehicles late, and drivers must take extra care near them.
¿Qué puede provocar sueño en el conductor?
What can make a driver sleepy?
- AÚnicamente dormir menos horas de las habituales.Only sleeping fewer hours than usual.
- BEl cambio de las horas habituales de sueño.A change in your usual sleeping hours.
- CDormir más horas de las habituales.Sleeping more hours than usual.
ExplanationCauses that can lead to drowsiness: the time of day (small hours of the night, 3:00-5:00, and early afternoon, 14:00-16:00); changes in your usual sleeping hours; the quality and amount of sleep; monotonous situations; sedative or stimulant substances; heavy meals; the temperature and ventilation inside the vehicle; individual differences between people and sleep disorders.
¿Qué efectos produce el estrés sobre el conductor?
What effects does stress have on the driver?
- ADisminuye el tiempo de reacción.It reduces reaction time.
- BEl comportamiento puede volverse más imprudente aceptándose más riesgos al volante, por lo que la conducción se vuelve más temeraria.Behaviour may become more reckless, with more risks accepted at the wheel, so driving becomes more dangerous.
- CLas reacciones serán más rápidas, por lo que la circulación será más segura.Reactions will be faster, so traffic will be safer.
ExplanationStress can seriously impair our ability to drive safely. Among other effects, it can cause reckless and dangerous behaviour, increase aggression, slow down decision-making and make distractions more likely.
Si tiene una alergia respiratoria, conviene...
If you have a respiratory allergy, it is advisable to...
- Aviajar al amanecer.travel at dawn.
- Bseguir el tratamiento y los consejos de su médico.follow your doctor's treatment and advice.
- Cconducir con las ventanillas abiertas.drive with the windows open.
ExplanationA respiratory allergy can cause sneezing, watery eyes and itchy eyes that make you lose your vision for a few moments, and antihistamines can cause drowsiness. So you must follow your doctor's treatment and advice; the doctor will tell you whether the medicine is compatible with driving.
¿Cómo puede la depresión afectar la conducción?
How can depression affect driving?
- ARecopilar demasiada información, incluso en situaciones sencillas.By gathering too much information, even in simple situations.
- BProvocar una sensación de falsa seguridad.By causing a false feeling of safety.
- CAumentando las distracciones.By increasing distractions.
ExplanationAccording to the Traffic and Road Safety Code and the General Driver Regulations, mental illnesses that affect attention, reaction or decision-making can be considered a risk to road safety. In particular, section 12 (perceptual-motor fitness) states that any impairment that puts the ability to drive safely at risk requires an additional assessment. Depression causes fatigue, low motivation and inner distractions, so it directly affects concentration and reaction time, making driving errors and states of distraction more likely. That is why depression directly affects the driver by increasing distractions.
¿El estado y el comportamiento del conductor pueden causar distracciones?
Can the driver's condition and behaviour cause distractions?
- ANo.No.
- BSí.Yes.
- CSí, pero solo cuando se conduce por autopista o autovía.Yes, but only when driving on a motorway (autopista) or dual carriageway (autovía).
ExplanationYes, the driver's condition and behaviour can cause distractions while driving. This is in line with the principles of attention and vehicle control set out in the Traffic and Road Safety Code. Factors such as fatigue, stress and drowsiness, mentioned in the rules, are examples of how the driver's physical and mental state can affect their ability to concentrate and keep control. The regulations also prohibit using devices that reduce attention, which supports the idea that the driver's behaviour must be optimal to ensure road safety.

La depresión provoca...
Depression causes...
- AQue se mantenga la concentración más fácilmente.concentration to be kept more easily.
- BQue se tomen decisiones más rápidamente.decisions to be made more quickly.
- CQue la sensibilidad respecto a la somnolencia y el cansancio aumente.greater sensitivity to sleepiness and tiredness.
ExplanationThe possible negative effects of depression on a driver include difficulty staying focused, more uncertainty when making decisions at the wheel, greater sensitivity to sleepiness and tiredness, and slower and poorer decision-making.

¿Cómo afectan las anfetaminas a la conducción?
How do amphetamines affect driving?
- ASe produce una fuerte somnolencia.They cause severe sleepiness.
- BAumentan la sensación de fatiga.They increase the feeling of fatigue.
- CDisminuyen la sensación de fatiga y producen falsa seguridad.They reduce the feeling of fatigue and give a false sense of security.
ExplanationAmong other effects, amphetamines delay sleepiness, but after a few hours a strong need to sleep may appear; this is called the rebound effect.

¿Qué puede favorecer la aparición de fatiga al volante?
What can make fatigue at the wheel more likely?
- ADescansar cada 2 horas o cada 200 kilómetros aproximadamente.Resting about every 2 hours or every 200 kilometres.
- BNo descansar el tiempo suficiente.Not resting for long enough.
- CCircular por una vía bien diseñada.Driving on a well-designed road.
ExplanationThe feeling of fatigue is a way the body protects itself. It is like an alarm signal showing that your abilities have reached their limit and that you need to recover energy to drive, or to keep driving, safely. The best way to recover and fight fatigue is to stop and rest every 2 hours.
Un factor que facilita la distracción del conductor es...
One factor that makes driver distraction more likely is...
- Auna situación de tráfico demasiado sencilla.a traffic situation that is too simple.
- Bla alta luminosidad del entorno.bright light in the surroundings.
- Cla baja luminosidad del entorno.poor light in the surroundings.
ExplanationPoor light in the surroundings can reduce visibility and affect the driver's concentration. According to the General Traffic Regulations, the driver must stay attentive and be able to control their vehicle at all times. Lack of light can be disorienting and increase the risk of distractions, which can lead to dangerous situations on the road.
¿Puede ser peligroso para la conducción llevar instalado un navegador GPS?
Can having a GPS navigator installed be dangerous for driving?
- ANo, pues ayuda y orienta al conductor.No, because it helps and guides the driver.
- BSí, si hacemos un mal uso de él ya que puede producir distracciones.Yes, if we use it wrongly, because it can cause distractions.
- CSí, si nos equivocamos de ruta.Yes, if we take the wrong route.
ExplanationUsing the GPS navigator wrongly, for example operating it while moving, can cause distractions and so lead to an accident.
¿Qué efecto produce el sueño en los conductores?
What effect does sleepiness have on drivers?
- ADisminuye el tiempo de reacción.It reduces reaction time.
- BAumenta las distracciones al volante.It increases distractions at the wheel.
- CSe está más concentrado.You are more focused.
ExplanationSleepiness increases reaction time, makes you less focused and increases the number of distractions at the wheel.
¿Cómo se llama el sistema de advertencia de distracciones del conductor?
What is the driver distraction warning system called?
- ADDR (Sistema de advertencia de somnolencia y distracción).DDR (drowsiness and distraction warning system).
- BBSM (Sistema de monitorización de ángulos muertos).BSM (blind spot monitoring system).
- CLDW (Sistema de advertencia de abandono de carril).LDW (lane departure warning system).
ExplanationDDR (drowsiness and distraction warning system) alerts the driver with a text message, with a picture of a steaming cup on the dashboard and even with vibrations in the steering wheel. The aim is for the driver to stop the vehicle until they are in optimal condition to continue.
Los conductores de vehículos de transporte de mercancías con MMA superior a 3.500 kg no pueden conducir con una tasa de alcoholemia superior a...
Drivers of goods vehicles with a MAM of more than 3,500 kg may not drive with an alcohol level above...
- A0,3 gramos por litro de sangre.0.3 grams per litre of blood.
- B0,5 gramos por litro de sangre.0.5 grams per litre of blood.
- C0,30 miligramos por litro de aire espirado.0.30 milligrams per litre of exhaled air.
ExplanationThe correct answer is 0.3 grams per litre of blood, because drivers of goods vehicles with a MAM of more than 3,500 kg are prohibited from driving with an alcohol level above that amount per litre.

Un conductor que acaba de obtener su primer permiso de conducción no podrá superar la tasa de alcohol de...
A driver who has just obtained their first driving licence may not exceed an alcohol level of...
- A0,15 miligramos de alcohol por litro de aire espirado.0.15 milligrams of alcohol per litre of exhaled air.
- B0,30 miligramos de alcohol por litro de aire espirado.0.30 milligrams of alcohol per litre of exhaled air.
- C0,25 miligramos de alcohol por litro de aire espirado.0.25 milligrams of alcohol per litre of exhaled air.
ExplanationA driver who has just obtained their first driving licence is a novice driver. So during the first two years of the licence, their maximum permitted alcohol level is reduced to 0.3 grams of alcohol per litre of blood or 0.15 mg of alcohol per litre of exhaled air. Do not confuse this with the obligation to display the novice driver sign on the vehicle, which lasts one year, whereas the alcohol level applies for 2 years.
Si tiene problemas para dormir, debe tener en cuenta que...
If you have trouble sleeping, you should bear in mind that...
- ADebe dormir más antes de conducir.you should sleep more before driving.
- BNo está en condiciones de conducir.you are not in a fit condition to drive.
- CNo es recomendable tomar muchos estimulantes para mantenerse despierto.it is not advisable to take a lot of stimulants to stay awake.
ExplanationUnder Spain's General Traffic Regulations, drivers must always be in a suitable physical and mental condition to drive a vehicle. People who have sleep problems are not in the best condition to drive, because tiredness can affect concentration, reactions and decision-making and significantly increases the risk of an accident.
¿Es adecuado conducir una motocicleta llevando como calzado unas sandalias?
Is it suitable to ride a motorcycle wearing sandals?
- ANo.No.
- BSí.Yes.
- CEs indiferente, el calzado no influye en la conducción de motocicletas.It makes no difference; footwear does not affect riding a motorcycle.
ExplanationSandals do not protect the foot in a fall and do not hold it firmly to work the rear brake and the gear lever. So they are not suitable and, in addition, since 1 October 2026 Article 118 of the General Traffic Regulations requires closed footwear covering the whole foot on a motorcycle.
Si bebes alcohol, ¿cuándo aumenta el riesgo de accidente?
If you drink alcohol, when does the risk of an accident increase?
- ACuando se supera el límite legal de alcohol en sangre.When you exceed the legal blood alcohol limit.
- BIncluso antes de llegar al límite legal.Even before you reach the legal limit.
- CEl riesgo aumenta según la cantidad consumida.The risk increases according to the amount you drink.
ExplanationAlcohol reduces the driver's ability to judge the situation correctly and slows down reflexes. Even small amounts of alcohol can affect visual perception and coordination. In Spain, the legal blood alcohol limit is 0.5 g/l for drivers in general and 0.3 g/l for professional drivers. However, the risk of an accident increases even at lower levels. Studies show that at 0.2-0.3 g/l the driver concentrates less and their ability to react to the unexpected decreases.

Mientras conduce recibe una llamada por el teléfono móvil, ¿puede contestar la llamada si para ello debe utilizar las manos?
While driving, you receive a call on your mobile phone. May you answer it if you have to use your hands to do so?
- ASí.Yes.
- BNo.No.
- CSí, si la conversación es breve.Yes, if the conversation is short.
ExplanationWhile driving it is prohibited to use a mobile phone or any other communication system; it is only allowed when the communication takes place without using your hands and without headphones, earphones or similar devices (Article 18.2 of the General Traffic Regulations, as worded by RD 518/2026).
Conducir con una tasa de alcohol en aire espirado superior a este valor constituye delito del art. 379 CP:
Driving with a breath alcohol level above this value is a crime under Article 379 of the Criminal Code:
- A0,50 mg/l.0.50 mg/l.
- B0,60 mg/l.0.60 mg/l.
- C0,65 mg/l.0.65 mg/l.
ExplanationThe criminal threshold is a breath alcohol level above 0.60 mg/l; neither 0.50 nor 0.65 is the correct legal figure.
Conduciendo un vehículo de transporte escolar, ¿cuál será la tasa máxima de alcohol por litro de aire con la que podrá circular?
When driving a school transport vehicle, what is the maximum alcohol level per litre of exhaled air with which you may drive?
- A0,30 mg.0.30 mg.
- B0,50 mg.0.50 mg.
- C0,15 mg.0.15 mg.
ExplanationThe correct answer is 0.15 mg. This is because school transport drivers have a maximum permitted alcohol level of 0.15 mg/l of exhaled air. It is important to follow this rule to ensure the safety of the passengers and avoid unnecessary risks while driving.
El estrés hace que el conductor...
Stress makes the driver...
- Asea más hostil con otros usuarios.more hostile towards other road users.
- Brespete más la señalización.respect road signs more.
- Ctome menos riesgos.take fewer risks.
ExplanationStress causes tension, impatience and irritability. A stressed driver tends to be more hostile and aggressive towards other road users, respects road signs less and takes more risks, which increases the likelihood of an accident.
¿Concentrarse en una conversación o discutir con un acompañante puede causar distracción?
Can concentrating on a conversation or arguing with a passenger cause distraction?
- ANo, hablar con el acompañante no causa distracción.No, talking to a passenger does not cause distraction.
- BSí, pero solo en trayectos largos.Yes, but only on long journeys.
- CSí.Yes.
ExplanationAn intense conversation or an argument with a passenger takes your attention away from the road and affects the driver's emotional state, on long or short journeys. Article 18.1 of the RGC requires constant attention to driving, so it is best to put arguments off.
La tasa máxima de alcoholemia permitida en aire espirado en los conductores durante el segundo año de su primer permiso es de...
The maximum breath alcohol level allowed for drivers during the second year of their first licence is...
- A0,25 miligramos por litro.0.25 milligrams per litre.
- B0,20 miligramos por litro.0.20 milligrams per litre.
- C0,15 miligramos por litro.0.15 milligrams per litre.
ExplanationAll drivers of vehicles, during the two years after obtaining their first driving licence or permit, are prohibited from driving with alcohol levels above 0.15 milligrams per litre of exhaled air or 0.30 grams per litre of blood. After those 2 years, they must meet the general level for all other drivers (including bicycles and personal mobility vehicles): 0.25 milligrams per litre of exhaled air or 0.50 grams per litre of blood.
Si padece una enfermedad crónica, ¿debe adoptar alguna precaución?
If you have a chronic illness, should you take any precautions?
- ASí, no debe conducir.Yes, you must not drive.
- BNo, cuando toma la medicación adecuada.No, if you take the right medication.
- CSí, preguntar al médico si tiene efectos sobre la conducción y seguir su consejo.Yes, ask your doctor whether it affects driving and follow their advice.
ExplanationIf we have a chronic illness, to reduce the risk of having an accident, we should always ask our doctor about the risks it involves for driving.
¿Para qué sirve el sistema ADAS "Detección de fatiga"?
What is the ADAS 'fatigue detection' system for?
- ATomar el control de la dirección del vehículo si el conductor está somnoliento.To take control of the vehicle's steering if the driver is drowsy.
- BEvitar un posible accidente por fatiga o sueño.To prevent a possible accident caused by fatigue or sleepiness.
- CRealizar una frenada de emergencia cuando detecte que el conductor no está en condiciones óptimas para continuar la marcha.To brake hard in an emergency when it detects that the driver is not in optimal condition to continue.
ExplanationThe purpose of the ADAS 'fatigue detection' system is to prevent a possible accident caused by fatigue or sleepiness. This is essential because driver fatigue is a significant risk factor for road safety and one of the main causes of accidents. The traffic rules mention the importance of the driver's attention and concentration, and recognising these states of fatigue can help the driver decide to stop and rest, and so prevent incidents. This is in line with the principles of driving rationally and efficiently to minimise risks on the road.

Una postura inadecuada en el asiento...
A poor seating position...
- Areduce la fatiga.reduces fatigue.
- Baumenta la fatiga.increases fatigue.
- Cno influye en la fatiga.does not affect fatigue.
ExplanationA poor position (too close to or too far from the steering wheel, or with the seat back leaning too far back) makes you tense your muscles and joints to compensate, which increases fatigue. A good position lets you use the controls without effort and delays tiredness.

Para prevenir la aparición de la fatiga es aconsejable parar a descansar durante 20 o 30 minutos...
To prevent fatigue, it is advisable to stop and rest for 20 or 30 minutes...
- Acada vez que encontremos en nuestro recorrido un área de descanso.every time we find a rest area on our route.
- Bcada 4 horas o cada 400 kilómetros de conducción.every 4 hours or every 400 kilometres of driving.
- Ccada 2 horas o cada 200 kilómetros de conducción.every 2 hours or every 200 kilometres of driving.
ExplanationTo prevent fatigue, it is recommended to rest for about 20 or 30 minutes every 2 hours or every 200 kilometres, and sooner if symptoms of tiredness appear. Waiting 4 hours or 400 kilometres is too long: by then fatigue has already reduced attention and made reaction time longer.
¿Qué tendrá en cuenta una persona con alergia respiratoria en el momento de conducir?
What should a person with a respiratory allergy bear in mind when driving?
- ATomar más medicación para evitar estornudar.Take more medication to avoid sneezing.
- BNada en concreto, si ya se está medicando.Nothing in particular, if they are already taking medication.
- CCircular con la ventanilla cerrada.Drive with the window closed.
ExplanationDraughts can make allergy attacks worse, because they contain a lot of pollen.
El efecto túnel provocado por la velocidad hace que el conductor...
The tunnel effect caused by speed means that the driver…
- Asea más sensible al deslumbramiento.is more sensitive to glare.
- Bsolo pueda percibir con nitidez los laterales de la calzada.can only see the sides of the carriageway clearly.
- Csolo pueda percibir con nitidez el centro de la calzada.can only see the centre of the carriageway clearly.
ExplanationAs speed increases, the field of vision narrows: the driver only sees the centre of the carriageway clearly and loses information from the sides, where pedestrians, cyclists or other vehicles may appear. This is the tunnel effect; to make up for it, you must keep your speed moderate and keep moving your eyes.
Durante un viaje largo, ¿qué se puede hacer para evitar la fatiga?
On a long journey, what can you do to avoid fatigue?
- ARealizar descansos suficientemente largos.Take breaks that are long enough.
- BBeber café en lugar de hacer pausas en la conducción.Drink coffee instead of taking breaks from driving.
- CPoner muy alto el volumen de la radio.Turn the radio up very loud.
ExplanationThe 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. Coffee or stimulant products help at first, because they remove the feeling of tiredness, but after a while the feeling comes back even stronger.

- B0,30 miligramos por litro de aire espirado.0.30 milligrams per litre of exhaled air.
- C0,15 miligramos por litro de aire espirado.0.15 milligrams per litre of exhaled air.
ExplanationDuring the first two years after obtaining the first licence, the driver is a novice driver and their maximum alcohol level is 0.15 mg per litre of exhaled air, or 0.3 grams per litre of blood. The general level of 0.25 mg per litre applies once those two years have passed.

¿Cuál de estos supuestos hace que disminuya el campo de visión?
Which of these situations reduces the field of vision?
- AUn retrovisor interior bien regulado.A properly adjusted interior mirror.
- BLas cortinillas transparentes.Transparent blinds.
- CEl número excesivo de viajeros.Too many passengers.
ExplanationToo many passengers in the vehicle, more than the number of seats, can reduce the driver's visibility, because when they check traffic in the mirrors they may find too many obstacles limiting their view to the rear and sides of the vehicle. For example, you will see better with a panoramic mirror with 2 people in the back of the vehicle than with 3.
La mala ventilación del habitáculo del vehículo...
Poor ventilation inside the vehicle...
- AFavorece la aparición del cansancio.makes tiredness more likely.
- BDisminuye la aparición del cansancio.makes tiredness less likely.
- CNo influye para nada en el cansancio del conductor.has no effect at all on the driver's tiredness.
ExplanationPoor ventilation and a high temperature inside the vehicle make driving less comfortable, which makes fatigue more likely and can even affect our physical and mental state.
