I saw a motorcycle pulled over by a marked unit that pulled out of the weigh station around lunch time that day.
BTW, what kind of camera/recording unit was used to capture the video/audio?
Yeah, the units started at Greenback, but after someone got ticketed, the pilot may have already clocked another driver. They started getting strung down 2 miles before they eventually doubled back. All of the speed timing was done 1/2 mile prior to Greenback.
BlackVue DR400G-HD camera, 1080p HD. 32GB microSD card. You can only buy the cameras on eBay at the moment - sold out of South Korea. I know several people who have bought them via eBay and everyone loves the units. They have issues if it gets super hot in parked cars though - but it takes just a second to take it down and stow in glove box when parking on a hot summer day.
