Can we overtake the grey vehicle on our left if we are driving at a higher speed on this road that has a lane reserved for traffic depending on the signposted speed?
A)Yes, because it is not considered overtaking.
B)Yes, because it is considered passing.
C)No.Correct
Overtaking must be carried out on the left as a general rule.
Exceptionally, we may overtake on the right:
- When the driver of the vehicle to be overtaken is clearly indicating their intention to stop or turn left, if there is sufficient space to do so.
- On two-way roads, on trams running in the centre of the road.
- On urban roads with more than one lane in the same direction, delimited by longitudinal markings.
In the case of the image, we are driving on a road where there is a lane reserved for traffic according to speed. On these lanes, you must drive on the right lane and may only use the reserved lane when circumstances require it, provided you comply with the signposted minimum speed. Overtaking must be carried out on the left.

There are lanes designated for various manoeuvres (acceleration, deceleration or waiting) and for certain types of vehicles (such as buses or taxis), in which it is not considered overtaking when a vehicle drives at a higher speed in one of these lanes compared to another. In such situations, it is permitted to drive at a higher speed in the right lane than in the left lane, since it would not constitute overtaking.
