     Explanation

404. Nº 404

     

     Al ver esta señal, ¿qué luces debemos encender, como mínimo, en nuestro ciclomotor?

     When you see this sign, which lights must we switch on, at least, on our moped?

     • ALa luz de posición.The sidelight.
     • BLa luz de cruce.Dipped headlight.
     • CLa luz de carretera, si el ciclomotor la lleva instalada.Main beam, if the moped has it fitted.

405. Nº 405

     Cuando se acerque a niños o personas mayores...

     When you approach children or elderly people...

     • Adebe tomar las precauciones necesarias para no ponerlos en peligro.you must take the necessary precautions so as not to put them in danger.
     • Bdebe avisarles mediante señales acústicas.you must warn them with your horn.
     • Cdebe detenerse para cederles el paso.you must stop to give way to them.
     Explanation

     The correct answer is that you must take the necessary precautions so as not to put them in danger. This comes from the driver's duty to take extra care when approaching vulnerable groups such as children and elderly people, who are more likely to have accidents because of their limited mobility. According to the General Traffic Regulations, drivers must be alert near areas with a lot of pedestrian traffic, especially vulnerable people, and must take steps to keep them safe. Warning them with the horn is wrong: although the horn may be used in some situations, it is not a suitable precaution. Stopping to give way to them may apply in some situations, but it is not the most complete or safest answer in all circumstances.

     • CAmarilloYellow
     Explanation

     Agricultural tractors and single-axle tractors must always have two rear sidelights that give a red light. These lights are compulsory for special vehicles that are allowed to drive at night, and also for those that are not allowed to drive at night.

407. Nº 407

     The vehicle's lights are a safety system that is...

     • AActiva.Active.

     Explanation

     If we are driving on a poorly lit road at 40 km/h or less, using main beam is optional. On the other hand, if the speed is over 40 km/h and there is no risk of dazzling anyone, main beam is compulsory.

     • CNo, llevar los faros mal reglados no influye en la seguridad.No, badly aimed headlights do not affect safety.
     Explanation

     If the headlights are aimed too low, the beam lights up a shorter distance and you see obstacles later, which leaves less time to react. If they are aimed too high, they dazzle others. That is why headlight aim directly affects safety.

416. Nº 416

According to Article 106 of the General Traffic Regulations, main beam is allowed in reduced visibility, such as fog. However, you must be careful not to dazzle other drivers, so the fog light is considered more suitable in these conditions.

421. Nº 421

     

     De noche, ¿Es obligatorio señalizar una carga que sobresale lateralmente más de 0,40 metros de la luz de posición?

432. Nº 432

     ¿Qué alumbrado dejaremos encendido al estacionar en una travesía insuficientemente iluminada?

     • Cse acorta la iluminación a larga distancia.long-distance lighting is shortened.
     Explanation

     If the headlights point too low, they only light the nearby area and long-distance visibility is reduced. If they point too high, they dazzle others. That is why their height must be adjusted according to the vehicle's load.

434. Nº 434
