A friend of mine drives a utility truck for the local gas company. They have just installed those gps monitoring systems that track location and speed limit of the vehicle, among other things. If he doesn't use his seat belt, exceeds the speed limit, etc., it sends a report back to hq. Since he has a heavy foot he's interested in something that will alert him when he is near the psl. I told him I thought the newer gps units have something like that built in. Does anyone have any suggestions? Please don't suggest getting another job.
