Never noticed this before, but I went through a toll barrier yesterday and get a laser alert, no cops anywhere around. Thought maybe I just didn't see them. Well on the way home I go through the same toll barrier's EZPass lane on the other side and get a laser alert again. I go through EZPass all the time never had that happen before. Could it have been something else at the toll barrier? Perhaps infrared lighting of your license plate to take pictures if you run the lane? I didn't notice any of those standard Halogen lights they normally use at that one. Older model V1 before rear laser, a little too worn to justify sending in for upgrades.
