Wisconsin Weigh Stations & Ag Inspection

When Wisconsin makes you pull in

Trucks over 10,000 lb gross must stop at an open Wisconsin weigh station (Trans 312); any truck must stop when an officer directs (Wis. Stat. 348.19(3)). Watch the lit ramp signs. OPEN means exit, and roadside message boards override your in-cab bypass display here. Blow past and it's a $50 to $100 forfeiture, rising to $100 to $200 for a repeat within a year (348.21(2)(a)).

Stations, bypass, and inspection

• Who must stop: Over a weight threshold
• Where the stations are: Fixed stations sit on I-94 (Kenosha, Hudson), I-90 (Sparta, Beloit), and I-39/I-43. Wis. Admin. Code Trans 312 governs 'open' stations; obey the lit signs and ramp signals. Wisconsin runs heavy portable and roving enforcement, and roadside message boards can override an in-cab bypass signal.
• Bypass: Both available. Drivewyze's busiest Wisconsin site is Hudson EB on I-94; PrePass covers Kenosha NB on I-94 and Sparta EB on I-90, among others. Wisconsin restriction: obey the roadside message board over your in-cab bypass display if the two conflict. Green light bypasses an open station; red or no signal means enter.
• Ag / border inspection: None. No agricultural or border produce-inspection checkpoints. Wisconsin enforces plant and pest rules through nurseries and paperwork, not roadside quarantine stops.
• Fine for passing an open station: Forfeiture of $50 to $100 for a first failure to stop, $100 to $200 for a second or later within 12 months (Wis. Stat. 348.21(2)(a)). Civil forfeiture, not a criminal misdemeanor.
