If car drivers in Spain always put the turn signal to the right or to the left in each maneuver that requires it, throughout the life of a car,
What is the most used intermittent?
In general, both turn signals will be used equally in most situations, since most maneuvers are usually compensated. If we put the turn signal to overtake another vehicle, then we have to put the opposite to rejoin our lane, for example.
The only case in which this does not happen is in the roundabouts, in which we should not put the flashing when we join but if we leave them on the right. So the right turn signal will be the most used.
