Kaleb's comment lines up with my own experience. I've observed that signal many times, and occasionally used (and given) it myself. Of course, this assumes you're running with your lights on at all times, but most trucks do. It also seems to be customary for the truck that's being let in to briefly turn its tail lights off and on to acknowledge the signal. One large U-Haul I rented had a momentary switch on the dash for this.
