- B0,15 miligramos por litro de aire espirado.0.15 milligrams per litre of exhaled air.
- C0,25 miligramos por litro de aire espirado.0.25 milligrams per litre of exhaled air.
ExplanationUnder Article 20 of the General Traffic Regulations, during the two years after obtaining the licence the maximum level is 0.15 mg/l of exhaled air or 0.3 g/l of blood. Watch out for the trap: 0.3 is the blood figure, not the breath figure.

What effects does fatigue have on drivers?
- AAumenta el campo visual.It widens the field of vision.
- BLa visión puede volverse borrosa.Vision may become blurred.
- CAumenta la sensibilidad auditiva.It increases sensitivity to sound.
ExplanationFatigue harms the driver's physical and mental abilities and causes changes in vision, such as vision becoming blurred. This relates to the rules that stress the importance of being in a suitable physical and mental state to drive, as mentioned in the regulations on the role of fatigue and drowsiness in road accidents. The option saying that vision may become blurred is the correct answer because it shows a direct effect of fatigue on the driver's perception, which is crucial for safe driving.

On a long journey, when should you rest?
- ACada 2 horas aproximadamente.About every 2 hours.
- BCuando encuentre un área de descanso.When you find a rest area.
- CCada 5 horas aproximadamente.About every 5 hours.
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.

Where do more distractions happen?
- AEn las carreteras convencionales.On conventional roads.
- BEn las vías urbanas.On urban roads.
- CEn autopistas o autovías.On motorways (autopistas) or dual carriageways (autovías).

- ALos movimientos son más rápidos y automatizados.your movements are faster and more automatic.
- BLa visión se vuelve borrosa y es más difícil enfocar la vista.your vision becomes blurred and it is harder to focus your eyes.
- CDisminuye el tiempo de reacción.your reaction time is shorter.
ExplanationSleepiness affects the driver's movements: they become slower and less precise and are carried out automatically. Vision becomes blurred, so it is harder to focus the eyes, and reaction time increases.
¿Pueden ocurrir durante el día accidentes de tráfico causados principalmente por el sueño?
Can road accidents caused mainly by sleepiness happen during the day?
- ASí, especialmente entre las 14:00 y las 16:00.Yes, especially between 14:00 and 16:00.

There is a higher risk of sleepiness on roads with...
- Amuchas curvas.a lot of bends.
- Bmucho tráfico.a lot of traffic.

If you have an illness, should you ask your doctor what precautions to take when driving?
- ANo.No.
- BSí.Yes.
- CSólo cuando la enfermedad es crónica.Only when the illness is chronic.
ExplanationYes, it is right to ask your doctor about the precautions to take for driving if you have an illness. Spain's traffic rules, in particular what the regulations say about diseases of the central nervous system and other medical conditions that can affect driving, state that drivers must not have illnesses that reduce motor, cognitive or coordination functions. That is why a medical assessment is essential to ensure safety at the wheel.

- AExclusivamente el estado del conductor.only the condition of the rider.
- BEl estado del conductor, del vehículo y de la vía.the condition of the rider, the vehicle and the road.
- CExclusivamente el estado de la vía.only the condition of the road.
ExplanationThe condition of the rider, the vehicle and the road all affect riding a motorcycle, because each of them can affect the rider's safety and performance. The rider's condition, such as their level of fatigue, their mood and their alcohol level, can affect their ability to react and make the right decisions. The condition of the vehicle, such as how the tyres, brakes and steering work, can affect the rider's ability to control it. And the condition of the road, such as the weather conditions and how well the rider adapts to the road, can affect grip and visibility. So all these factors are important for riding a motorcycle safely.

Bajo los efectos de la depresión...
Under the effects of depression...
- ADisminuyen las distracciones.distractions decrease.
- BSe pierde información del entorno.information about the surroundings is missed.

ExplanationFatigue mainly appears when driving for many hours in a row or with insufficient breaks. It is recommended to stop and rest at least every two hours or every 200 kilometres; keeping a constant speed does not cause fatigue on its own, and driving with normal habits does not prevent it.
Conducir un vehículo a motor o ciclomotor con una tasa de alcohol superior a 1,2 g/l en sangre:
Driving a motor vehicle or moped with a blood alcohol level above 1.2 g/l:
- AÚnicamente puede ser sancionado con una multa de tráfico y la suspensión del permiso.can only be punished with a traffic fine and suspension of the licence.
