Weigh-in-motion (WIM) scales are embedded scales that can weigh vehicles while they are in motion on interstate roadways. This type of scale works by using sensors in the road and imaging technology to tell what kind of vehicle is currently on the scale and how much each axle weighs. These systems can tell if a trucks load is properly balanced or heavy on an axle group which can affect handling. Some of the more sophisticated systems can tell which tires are low on pressure as well. The accuracy of weigh in motion systems are continuing to improve and can provide weights with 3% error or less.

Carriers have a tough job seeing freight makes it to destination without incident. Getting loaded at the shipper is one stop along the way that should be seamless. So what happens when a driver knows they have been overloaded by the shipper and there's an attempt to get the driver on the road anyway?
The responsibility of safely transporting goods in the United States rests on the shoulders of an estimated 3.5 million truck drivers. All of those drivers are trying to maximize their loads and minimize the amount of time spent running to scales and avoiding weigh stations.
