Spain's War on Speed, Part II

No photos this time, just a friendly travel advisory:

You know how, in the U.S., you'll often see signs that say "speed monitored by radar," and it's just kind of a general warning that a cop might be sitting behind a berm waiting to catch you for going too fast? Well, in Spain those signs actually mean something. All over the country on the motorways, Spain has installed little boxes that monitor your speed and take pictures of your license plate if you go too fast. They then mail you a speeding ticket, and deduct a set number of "points" from your license. (Enough deductions, and you can't drive anymore.) However, as part of the surveillance law that enabled these boxes, the authorities must notify you of any unmanned radar installation. So when you see a big sign warning you to slow down, you can be sure that one of these radar-camera boxes is about a half-mile down the road.

The good news is that once you figure out what the boxes look like, you'll know when you've passed one of them. Then, you can resume whatever speed you were traveling before.
