In this cross-town road, what is the maximum speed allowed?

Explanation
Traffic regulations establish as a general rule that the maximum speed you can drive on a cross-town road is 50 kilometers per hour except when there is some speed limit sign indicating the maximum speed you can drive on that section of road, as in the image. Therefore, in this case the maximum allowed speed according to the speed limit sign is 40 kilometers/hour.
