Wisconsin Work Zone Laws

How Wisconsin handles work zones

Wisconsin doubles your fine only when workers are at risk from traffic in the zone (Wis. Stat. 346.57(5)), the 'workers present' catch. An empty, signed work zone carries the normal forfeiture, but the posted reduced limit still binds you. Wisconsin has no statewide handheld ban, yet it bars all handheld phone use inside a work zone, hands-free only (Wis. Stat. 346.89(4m)), stricter than its statewide texting rule. Hurt someone in the zone and it climbs to $10,000 and 9 months.

Speed, fines, phone, and the flagger

• Speed rule: Obey the posted reduced work-zone limit. Fines double only where workers are actually at risk from traffic in the maintenance or construction area (Wis. Stat. 346.57(5)). No crew at risk means no doubling, but the posted limit still stands whenever the signs are up.
• Fine multiplier: Forfeitures doubled when workers are at risk from traffic in the work zone (Wis. Stat. 346.57(5)). It covers work-zone speeding and the other fixed speed-limit violations under 346.57, not reckless driving. Workers-present trigger; an empty, signed zone carries the normal fine.
• Phone in a work zone: Restricted — put it down
• Flagger authority: Obey the flagger. No driver may fail to comply with a lawful order, signal, or direction of a person controlling traffic (Wis. Stat. 346.04). A work-zone flagger's STOP/SLOW paddle carries that authority, and disobeying it is a citable offense.
• Base fine: A Wisconsin speeding forfeiture runs roughly $175 to $300 with costs depending on how far over you were, and it is doubled when workers are at risk in the zone. Cause bodily harm inside the work zone and you face up to $10,000 and 9 months (Wis. Stat. 346.57(5)).
