Here's a link (link) to a webcam streaming a live shot in Jackson Hole, Wyoming. Why would I post this on the P-51 Blog? Because this is a great shot of an intersection where the left turn can be either "protected" or "unprotected," and it shows how to properely do this, and it shows a flashing yellow to indicate the "unprotected" left turn. Flashing yellows have been used in other States for many years, but are now finding their way to Calif. Check out the feed!
