What Happens at a California Weigh Station

When a California 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 California station takes part varies, so follow your in-cab signal and the roadside signs: when they tell you to pull in, pull in.

Federal Weight Limits

Gross vehicle weight	80,000 lbs
Single axle	20,000 lbs
Tandem axle	34,000 lbs

Interstate System, 23 CFR Part 658. States may allow more with permits.
