The reason some trucks bypass the scales when they are open is that they have "PRE-PASS". Pre-Pass is a little box that sits inside the truck on the window an is read by a sencor an atomated scales that are layed into the road bed. The truck passes over the scale's the sencor picks up the Pre-pass box which tells the scal master who the truck is (ie;company, trk unit, etc), if the weight master has no reason to either inspect the truck or look at it for some reason an the truck is not over weight on any axle or gross weight they give the driver a green light signal inside his cab which is located on the pre-pass unit an he or she drives by. If the scale master wants the truck to stop he sends a signal that turns on the red light inside the cab an thus the truck has to pull into the scale. This unit saves alot of time for both the scale masters an the drivers, it gives more time of scale masters to inspect trucks that need it an give drivers more time to complete a trip in the long run. Some trucks do not like these pre-pass units because it logs the time you cross that scale an down the road it can be determined if you are running legal or not by the scale master looking at the time you have passed his scale an the time you have passed the last or for that mater any other scale that logs the truck in. I run legal all the time, my company demands it, we run 48 states an train drivers so we run as a team in most case's, having the pre-pass saves us in some case's over three hours from coast to coast, so it a god sent to me :O) hope this helps you :o)
