Si tras un accidente de tráfico, un herido no responde y aparentemente ha perdido la conciencia, ¿qué es lo primero que debemos hacer?
After a road accident, an injured person does not respond and seems to have lost consciousness. What should you do first?
- ABuscar hemorragias externas o internas, para evitar que se desangre.Look for external or internal bleeding, to stop them bleeding to death.
- BAbrir la vía aérea y retirar cuerpos extraños de la boca, mediante maniobras que no manipulen la columna.Open the airway and remove foreign objects from the mouth, using manoeuvres that do not move the spine.
- CTumbarle en la denominada posición lateral de seguridad, para que respire con mayor facilidad.Lay them in the recovery position, so that they can breathe more easily.
ExplanationWhen a person is unconscious after a road accident, the priority is to make sure they can breathe properly. Opening the airway and removing any blockage is essential for the body to get enough oxygen. But do it carefully and do not move the spine, as the accident may have caused serious injuries there. It is crucial to follow the right procedure in emergencies like this, because acting wrongly could make the injured person's condition worse.
¿En qué épocas del año se producen más accidentes de circulación?
At what times of year do most road accidents happen?
- AFuera de los periodos vacacionales.Outside holiday periods.
- BEs indiferente.It makes no difference.

If you come across an accident where help is already organised, must you stop to help?
- ASí, en vías interurbanas o donde no exista poste SOS.Yes, on roads outside built-up areas or where there is no SOS post.
- BNo, si no está implicado debe continuar la marcha.No. If you are not involved, you must continue on your way.
- CSí, debe detenerse y colaborar siempre.Yes, you must always stop and help.
ExplanationAnyone who witnesses, comes across or is involved in an accident must help when necessary, as long as there is no risk to themselves or others. If help is already organised when you arrive at the scene, you do not have to stop.
Siempre que sea posible, ¿cómo hay que inmovilizar un vehículo implicado en un accidente?
Whenever possible, how should a vehicle involved in an accident be immobilised?
- ACon calzos u otro objeto que sirva para eso.With wheel chocks or another object that serves the purpose.
- BApagando el motor y poniendo el freno de mano.By switching off the engine and applying the handbrake.
- CDesconectando los terminales de la batería.By disconnecting the battery terminals.
ExplanationTo stop the damaged vehicle from moving or catching fire, you must switch off the engine by turning off the ignition and apply the handbrake. Chocks are not the first step and are not always available, and handling the battery takes time and can be dangerous.

- AEn las autopistas y autovías.On motorways (autopistas) and dual carriageways (autovías).
- BEn las vías urbanas.On roads in built-up areas.
- CEn las vías interurbanas.On roads outside built-up areas.
ExplanationIn built-up areas, where there are more pedestrians, the chance of being hit is much higher. Injuries are more serious on roads outside built-up areas, because vehicles travel faster there. Pedestrians are not allowed on motorways and dual carriageways.

- CRegularemos el tráfico, socorreremos a las víctimas y avisaremos a los servicios de emergencia.Direct the traffic, help the victims and alert the emergency services.
ExplanationIn an accident it is important to act in the right order so that help is quick and effective. This order is given by the PAS rule (protect, alert, help: in Spanish proteger, avisar, socorrer), which you should always apply. 1. PROTECT: take all necessary measures to protect yourself, the accident scene (by marking the area) and the victims. 2. ALERT: alert the emergency services by calling 112. 3. HELP: look after the accident victims.
¿Con qué fin pondremos a los heridos en posición de defensa?

- APara que estén más relajados.So that they are more relaxed.
- BPara hacerles la reanimación boca a boca.To give them mouth-to-mouth resuscitation.
- CPara evitar que se asfixien.To stop them from choking.
ExplanationThe recovery position keeps the airway open and reduces the risk of choking if the person vomits. That is why it is the best position if the injured person is unconscious.

Whenever possible, how should a vehicle that has been involved in an accident be immobilised?
- ACon calzos o con cualquier objeto que haga la misma función.With wheel chocks or any object that does the same job.
- BCortando el contacto y poniendo el freno de mano.By switching off the ignition and applying the handbrake.
- CDesconectando los bornes de la batería.By disconnecting the battery terminals.
ExplanationTo immobilise a crashed vehicle safely, switch off the ignition, which reduces the risk of fire, and apply the handbrake so that it does not move. Chocks may help afterwards, but they are not the first step, and there is no need to touch the battery.

- ANo, en ningún caso, ya que son sucesos inevitables.No, never. They are unavoidable events.
- BSi, en general, ya que son sucesos predecibles.Yes, in general, because they are predictable events.
- CSi. pero solo si se mejoran las condiciones de las víasYes, but only if road conditions are improved.
ExplanationRoad accidents are generally predictable events. If they were truly 'accidental', they would depend only on the time spent at the wheel. But this is not so: certain circumstances of the vehicle, the road, the surroundings and, above all, the driver make an accident more likely or more serious. These circumstances are called 'risk factors'. By avoiding them we reduce the chance of a crash to a minimum.
El factor entorno, ¿es un factor de riesgo?

- ASí.Yes.
- BNo.No.
- CNo, solo lo son el factor humano y el vehículo.No, only the human factor and the vehicle are.

It must be placed on the highest point of the broken-down vehicle, to make it as visible as possible. Today the V-16 is the only legal way to signal a broken-down vehicle or an obstacle on the road. Warning triangles are no longer used.

¿Cómo se denominan los costes de pérdida de vidas, de capacidad productiva y el sufrimiento físico y psicológico que tienen lugar como consecuencia de un accidente de tráfico?

ExplanationIf you break down, by day or by night, you must use the hazard warning lights and also place the hazard warning device. The V-16 hazard warning device is an approved amber-yellow light with geolocation. It runs on its own power supply (batteries). It must be placed on the highest point of the broken-down vehicle, to make it as visible as possible. Today the V-16 is the only legal way to signal a broken-down vehicle or an obstacle on the road. Warning triangles are no longer used.
Si el vehículo se detiene por avería en el arcén de una vía interurbana...
If your vehicle breaks down and stops on the hard shoulder of a road outside a built-up area...
