Overrating their driving ability or having a lower perception of risk are behaviours that, in general, make young drivers...
- Atengan menos probabilidad de sufrir un accidente.less likely to have an accident.
- Btengan más probabilidad de sufrir un accidentemore likely to have an accident.

- Acada tres horas.every three hours.
- Bcada media hora, como mínimo.every half hour, at least.

- CSí, porque el vehículo no está en movimiento.Yes, because the vehicle is not moving.
ExplanationUnder the General Traffic Regulations, using mobile phones while driving is prohibited, except in specific circumstances. The correct answer is the option about a hands-free system, because using a mobile phone is only allowed if you have a hands-free device that does not need earphones. This rule exists to prevent the driver from being distracted and to ensure road safety, because using the phone can take away the attention needed to drive safely.

Driving on a road with a lot of traffic...
- Afavorece la aparición de la fatiga.makes fatigue more likely.
- Bretrasa la aparición de la fatiga.delays fatigue.
- Cno es una circunstancia que afecte a la fatiga.does not affect fatigue.
ExplanationAnything that requires high concentration from the driver or makes driving less comfortable will make them tired sooner and make fatigue more likely.

For novice drivers (during the first 2 years of holding the licence) and professional drivers, the maximum level allowed is 0.3 grams of alcohol per litre of blood or 0.15 milligrams per litre of exhaled air. The only completely safe level at the wheel is 0.0.

¿Cuál de los siguientes es un síntoma de que el conductor empieza a sentir fatiga?
Which of the following is a symptom that the driver is starting to feel fatigue?
- AMovimientos más rápidos, precisos y eficaces.Faster, more precise and more effective movements.
- BConducción más automática y menos activa.More automatic and less active driving.
- CDisminuye el número de parpadeos y duran menos.Blinking less often and for a shorter time.
ExplanationDriver fatigue can significantly affect the ability to react and pay attention. According to the General Traffic Regulations, especially the sections dealing with drowsiness and fatigue as risk factors, fatigue tends to cause more automatic and less active driving. This is because a tired driver tends to lose concentration and react more slowly to stimuli around them. So the option about more automatic and less active driving is correct, because it describes exactly this effect of fatigue.

La depresión, ¿puede afectar a la conducción?
Can depression affect driving?
- ANo, en ningún caso.No, never.
- BSí, cuesta más trabajo mantener la atención necesaria, por ejemplo.Yes, for example it is harder to keep the necessary attention.

Does the condition of the road affect the driver's physical and mental abilities?
- ANo, solo afecta al estado del vehículo.No, it only affects the condition of the vehicle.

- ADisminuya el tiempo de reacción.your reaction time shorter.
- BSea más difícil mantener la concentración en el tráfico.it harder to stay focused on the traffic.
- CSea más fácil mantener la concentración en el tráfico.it easier to stay focused on the traffic.
ExplanationDrowsiness makes the driver's reaction time to something unexpected longer, reduces their concentration on the traffic and increases distractions at the wheel. Microsleeps may also sometimes happen, especially if we drive in the early hours of the morning.

- Cuna taza de café elimina la fatiga y le ayuda a concentrarse.a cup of coffee removes fatigue and helps you concentrate.

Beber alcohol...
Drinking alcohol...
- APuede disminuir el tiempo de reacción.may reduce reaction time.
- BFavorece la aparición del sueño.makes sleepiness more likely.
- CAumenta la capacidad de reacción.increases the ability to react.

- Bse comporte de una forma más peligrosa.behave more dangerously.

ExplanationSleepiness reduces our ability to pay attention and can lead us to accept a higher level of risk and, for example, drive faster, especially when we are close to our destination and very keen to arrive. 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.
