Under the rules on driver assistance, AEBS must be able to warn the driver and, if there is no response, take control of the vehicle to stop it. This is supported by the General Traffic Regulations, which stress the importance of active safety and of technologies that reduce the risk of road accidents, helping to respond quickly in emergencies.

- CSí, llevando dos retrovisores exteriores, uno a la derecha y otro a la izquierda.Yes, if the vehicle has two exterior mirrors, one on the right and one on the left.

Adhesive films or sun blinds are only allowed on the rear windows, and for this the vehicle must have two exterior mirrors. A novice driver, like any other driver, may have blinds on the rear window of their vehicle as long as the right mirror is fitted, because they will not have enough view through the interior mirror. The left mirror is always compulsory.

The driver must check the mirrors briefly without losing control of the situation on the road. Constantly taking attention away from the traffic ahead, even for a short time, reduces the ability to react to sudden obstacles, pedestrians and other vehicles' manoeuvres.

ExplanationThe windscreen wipers and washer are essential parts for making sure the driver can see in the rain or when the windscreen is dirty. The General Traffic Regulations stress the importance of keeping water in the washer reservoir, because if there is no fluid the system cannot work properly, which puts road safety at risk. The correct answer is that you must check the water level in their own reservoir, so that the wipers can work properly and give good visibility.
