We already do have special lanes reserved for truckers. At all but the smallest of border crossings, there is commercial processing and then there's passenger processing. They are separate.
In addition to that, I spoke of cards issued under the free and secure trade program. They're meant to expedite the flow of frequent trade across the border by known entities. At a number of our border crossings we have dedicated lanes even for that. So they really do exist already.
I must admit, I didn't understand the first part of your question. I'm familiar with the radiation detection portals at the border. Is that what you're referring to?
They're just a reality. What I think about them is immaterial. They're already in place at all U.S. border crossings. They don't emit any radiation. They're just there to detect radiation. I can tell you that every single U.S. customs and border protection officer at the border also carries one as part of his kit.
They haven't caused any major disruptions for us. Every now and then they do malfunction, and that can cause problems. However, it has not been a major issue for us.
