Warning for Orihuela parking rules.

I have read this:

Do you want to visit Orihuela you have to be careful where to park your car. If you do not live en Orihuela it is forbidden to park in the orange zone. The orange zone is only for citizens of Orihuela. The citizens have a authorization in the front window of the car. If you do park in the orange zone it costs 40 euro and the police has the power to tow away the car.
