An additional right lane for slower moving vehicles?

Answer 1

Yes. There are usually 3 lanes on a normal highway/freeway/parkway or whatever you'd like to call it. The one closest to the barriers or borders between which way the car goes is the fastest lane. That is usually if you need to get somewhere fast and people almost never linger in that lane going at low speeds. The middle is for going at an average speed and usually has the most traffic. It's like the Economy section of an airplane, nothing special. The last lane, and the government might add a 4th lane, is the slowest. Usually if your a tourist and need to constantly see whcih way to go, that is the slowest lane and the only lane(s) dump-trucks, tractor trailers, and heavy vehicles are allowed to veer off into. It's also nice because they don't slow anyone down since it IS the slow lane. But it is a pain in the @$$ to try to exit while ones in front of you. Hope this helped.
