Let me preface that this detection would have been much further. I passed this accident and the Troop car was blasting 34.7. But as I passed I could tell they were wrapping it up. So I tried to get as far away as I thought I could get away with before they left the site. I turned around in the nearest place I could find without pushing my luck and sure enough as you'll see, just as I got back the Trooper was getting in his car to leave. As you see as soon as I turned around I started to record, the R is alerting more than weakly immediately. If I could have gone farther I think this would have been closer to 2.5 miles or more.
