In Spain international driving licenses are recognised.
About the permission to circulate you have to ask for information at Provincial Headquarters of Traffic.
If you wish to travel to Spain in your own vehicle, be it a car or a motorcycle, or rent one once you reach your destination, you should know that the Spanish government recognizes, almost without exceptions, the totality of the driving licenses issued in the world. The validity of these licenses lasts for the period of validity of appearing in the licenses. Only if you acquire residence in Spain, the validity of your permit will be limited to a year.
Remember that, together with your driving license, you must check that your liability insurance is in order, and that you have the corresponding Green Card.
