Weighing Stations

While in KY I saw several weighing stations. Does one have to stop at every station one comes across?

If they are open and you don't have a Pre-pass. You even have to go in if the Pre-pass is turned off or you get a red light on the Pre-pass.

Pre-pass???

Ever notice just before some scales you have a pole with an arm sticking out over the right lane & wondered why & what it is? That is the sensor arm for the trucks that have the Pre-pass. It is most times a Weight-in-motion setup that weighs the truck as it goes past & relays that info to the scale house. Typically you have 2 sensors spaced apart, the first one you will notice has a couple of bars set into the roadway, that is the weigh-in-motion scale that weighs your axles as they cross it. The second sensor is the one that gets the signal back from the scale house that triggers the Pre-pass in the truck to alert the driver if they are allowed to by-pass or not.

Thanks Ernie, guess I will know more when I really get into it. Just out of curiosity, what happens if your weight is not legal, do they stop you at the next weigh station?

...sorry...I see that a pre-pass can be triggered to alert a driver. SInce you did not drive in where do you stop if you are not allowed to by-pass?

The prepass will alert you in time to enter the scale if you have to stop. If the scale is open and the prepass does not alert you either way you have to stop.

What if I just avoid scales altogether? I haul dry bulk.

Good question but I would suggest worrying about obtaining your CDL 1st. Your instructor or trainer will go over all of this with you so I wouldn't worry about the small stuff till later.
