      Oh, I didn’t realize that was specifically telling the drivers in the video that they were too tall. I thought it was just a general warning to anyone passing through.

        No, it actually measures vehicles if they’re short enough to pass. My guess would be a IR receiver-transmitter combo with a simple “flash if tripped” circuit, but still, that is enough to draw the driver’s attention.
