What are the scanners before weigh stations?
WIM systems, as indicated above, are commonly used to screen vehicles on the mainline for weight compliance as they approach a weigh station. The WIM scale or sensor embedded in the pavement automatically weighs vehicles and provides an estimate of the vehicle’s weight to station personnel for sorting purposes.
What happens if you accidentally drive through a weigh station?
For example, if a trucker skips a required weigh station, they could be pulled over by a law enforcement officer, who may direct the trucker to drive back to the weigh station. And that can lead to additional delays because even more of your trucks could be required to stop at weigh stations on the future.
Why do some trucks get to bypass weigh stations?
In short, truckers who have PrePass generally get to bypass the scale, and the scales have the ability to monitor it. When the trucks are due for inspections, PrePass will send them through the scales until they receive and pass a full mechanical/driver inspection.
Why do some semis stop at weigh stations and some don t?
If a truck is too heavy, a citation and a fine can be issued. If the weight makes the truck unsafe to operate, then it could be forced to stay at the station until the situation is rectified in some way.
What are the things that hang over the highway?
A These are global positioning system reference stations, used for surveys and to monitor the shaking of the Earth. There about 40 on Caltrans property, mostly in central and Northern California along Highway 152 and Interstate 5.
What is a WIM site?
Weigh-in-motion or weighing-in-motion (WIM) devices are designed to capture and record the axle weights and gross vehicle weights as vehicles drive over a measurement site.
Do Bobtails have to stop at scales?
When you get near the scales, the signs tell you that states requirments (usually boils down to weight). If your bobtail weighs less that what’s posted on the sign, you don’t have to scale, unless the sign also says something like “all trucks must weigh”. Your best bet would be to stop and scale, just in case.
What trucks must stop at weigh stations?

How do trucks know when to stop at weigh stations?
When a truck driver sees an open weigh station in a state requiring stops, they must pull off and roll onto the scale. The scales are convenient and allow the truck driver to stay in the vehicle the whole time. If a red light flashes, then the driver must resolve the weight issue.
Why do they cut rectangles in the road?
On freeways, these rectangles usually indicate the presence of a traffic counter. “They can monitor traffic and tell Caltrans, or whoever is using them, that there are 10,000 cars an hour coming through a certain area,” Terry said.
What is a weigh station and where is it located?
A weigh station is a designated location, typically located directly off of highways, where the Department of Transportation or state highway patrol inspects the weight of a vehicle.
