It's pretty difficult to tell it apart from the default version. When you see it exactly in front or behind yourself, diamond should be narrower and a bit more thin. But if it appears from the side, the task becomes way harder.

Also you should be careful if you stay on some tight single-lane road, because it makes the comparsion of sizes kind of unclear.
