What Happens at a Illinois Weigh Station
When a Illinois weigh station is open, trucks above the state’s weight threshold leave the highway and roll across the scale at low speed. A signal or a loudspeaker tells you to return to the highway or to park for a closer look. Officers can check your weight per axle, your credentials and your hours-of-service records, and they may inspect the vehicle itself.
If you’re overweight, you may get a fine and have to shift or remove part of the load before you can continue. Weighing first on a certified truck scale at a truck stop avoids most surprises.
Bypass Systems and Weigh-in-Motion
Many states pre-screen trucks at highway speed with weigh-in-motion sensors and electronic bypass programs such as PrePass or Drivewyze. Whether a particular Illinois station takes part varies, so follow your in-cab signal and the roadside signs: when they tell you to pull in, pull in.
