Wisconsin traffic laws cover speed, right-of-way, seat belts, distracted driving, impaired driving, and crash reporting, and the state enforces them through fines, a demerit point system that suspends your license at 12 points in a year, and criminal penalties for the most serious offenses. The rules below are what Wisconsin statutes actually require, and what happens when you fall short.
Speed Limits
Wisconsin sets default speed limits by road type unless a sign posts something different:1Wisconsin State Legislature. Wisconsin Code 346.57 – Speed Restrictions
- 25 mph on city and village streets outside outlying districts
- 35 mph in outlying districts of a city or village and in semi-urban areas outside city or village limits
- 55 mph on all other roads with no posted limit
- 65 mph on expressways
- 70 mph on freeways, including interstate highways, and on expressway sections that use interchanges only
The posted number is only half the rule. Wisconsin also requires you to drive at a speed that is reasonable and prudent for conditions, which means slowing down near intersections, curves, hill crests, school zones, and construction zones, or whenever weather limits visibility. An officer can cite you for driving too fast for conditions even when you are under the posted limit.
School crossings carry a 15 mph limit whenever children are present or a crossing guard is in the roadway. Construction zones are treated more seriously still: penalties double when workers are present, and injuring someone in a work zone can mean thousands of dollars in fines and up to three and a half years in prison.2Wisconsin Department of Transportation. Work Zone Safety
Right-of-Way at Intersections and Crosswalks
When two vehicles reach an uncontrolled intersection at roughly the same time, the driver on the left yields to the driver on the right. A vehicle already on a through highway has the right-of-way over one still approaching, and the approaching driver must stop before entering.3Wisconsin State Legislature. Wisconsin Code 346.18 – General Rules of Right-of-Way At a four-way stop, you stop first, then yield to any vehicle close enough to create a collision risk. When several arrive at once, the vehicle on the right goes first.
Pedestrians get different protections depending on the crosswalk. At a signal-controlled crosswalk, drivers yield to pedestrians who started crossing on a green light or Walk signal.4Justia. Wisconsin Code 346.23 – Crossing Controlled Intersection or Crosswalk At uncontrolled crosswalks, you yield to any pedestrian or cyclist already crossing within a marked or unmarked crosswalk. Pedestrians cannot step off the curb into the path of a vehicle too close to stop.5Wisconsin State Legislature. Wisconsin Code 346.24 – Crossing at Uncontrolled Intersection or Crosswalk When any vehicle stops at an intersection to let a pedestrian cross, drivers behind it cannot pass.
At a stop sign, stop before the marked stop line. With no line, stop before the crosswalk. With neither, stop at a point where you can see cross traffic.6Wisconsin State Legislature. Wisconsin Code 346.46 – Vehicles to Stop at Stop Signs and School Crossings A yield sign does not require a full stop, but you must slow enough to give right-of-way and stop if needed to avoid a collision. Right turns on red are allowed after a full stop unless a sign prohibits them, and only after yielding to pedestrians, cyclists, and cross traffic.7Wisconsin State Legislature. Wisconsin Code 346.37 – Traffic-Control Signal Legend
Signaling, Passing, and Lane Changes
Before turning or changing lanes, signal continuously for the last 100 feet you travel. Cyclists and electric scooter riders need 50 feet.8Wisconsin State Legislature. Wisconsin Code 346.34 – Turning and Stopping and Required Signals on Turning and Stopping
Pass on the left, and only when the left side of the road is clearly visible and free of oncoming traffic for long enough to complete the pass. Do not pull back right until you are safely clear of the vehicle you passed.9Wisconsin State Legislature. Wisconsin Code 346.09 – Limitations on Overtaking on Left or Driving on Left Side of Roadway Passing is prohibited across double yellow lines, on curves, and near hill crests where sight distance drops. If you are being passed, stay right and do not speed up.
Emergency Vehicles and the Move Over Law
When an authorized emergency vehicle approaches with its siren on, pull as far right as possible, clear of any intersection, and stop until it passes.10Wisconsin State Legislature. Wisconsin Code 346.19 – What to Do on Approach of Emergency Vehicle
Wisconsin’s move over law reaches further. Whenever an emergency vehicle, tow truck, highway maintenance vehicle, utility vehicle, or disabled vehicle with hazard lights is parked on or within 12 feet of the roadway, you must move into a lane not next to it, or if you cannot change lanes safely, slow to a reduced speed and be prepared to stop.11Wisconsin State Legislature. Wisconsin Code 346.072 – Passing Certain Stopped Vehicles A violation can bring a fine and suspension of your driving privileges.
Distracted Driving
Wisconsin bans composing or sending any text message or email while driving, and the ban covers every driver, not just beginners.12Wisconsin State Legislature. Wisconsin Code 346.89 – Inattentive Driving Hands-free or voice-operated devices are allowed for calls, but you cannot physically hold a phone to dial or talk.
Drivers with a probationary license or learner’s permit cannot use a cell phone at all while driving, except to report an emergency. Commercial drivers also cannot use a hand-held phone. In highway work zones, utility areas, and emergency response areas where workers face traffic, every driver must go fully hands-free. The general inattentive driving rule reaches other distractions as well, from eating to adjusting a navigation system, each of which can draw a citation on its own.
Seat Belts and Child Restraints
Every occupant must wear a seat belt at any seating position where one is installed, front or back.13Wisconsin State Legislature. Wisconsin Code 347.48 – Safety Belt Use Requirements
Children under 8 need a restraint matched to their age, weight, and height:14Wisconsin State Legislature. Wisconsin Code 347.48 – Child Safety Restraint Requirements
- Rear-facing car seat for children under 1 year old or under 20 pounds; the seat goes in back if the vehicle has a rear passenger seat
- Forward-facing car seat for children at least 1 year old and 20 pounds but under 4 years or under 40 pounds
- Booster seat for children at least 4 but under 8 years old, weighing 40 to 80 pounds and 57 inches or shorter
- Standard seat belt for children under 8 who do not fit the categories above
Violating the restraint rule for a child under 4 carries a fine of $30 to $75.15Wisconsin Department of Transportation. Seat Belt Law
OWI and Impaired Driving
Wisconsin’s legal blood alcohol limit is 0.08% for regular drivers and 0.04% for commercial drivers.16Wisconsin State Legislature. Wisconsin Code 346.63 – Operating Under Influence of Intoxicant or Other Drug A first OWI is a civil forfeiture rather than a criminal charge, with a fine of $150 to $300, a mandatory $435 OWI surcharge, and license revocation for six to nine months. A BAC of 0.15 or higher adds a one-year ignition interlock requirement. Repeat offenses escalate hard: a fourth OWI is a Class H felony carrying 60 days to six years in prison and a fine of $600 to $10,000, plus the $435 surcharge.17Wisconsin Department of Transportation. OWI and Related Alcohol and Drug Offense Penalties
Wisconsin applies zero tolerance for restricted controlled substances. Any detectable amount of a drug such as THC in your blood can support an OWI charge without separate proof of impairment, and prescription medications can lead to charges if they affect your driving. Under the implied consent law, refusing a chemical test triggers automatic license revocation and may require installation of an ignition interlock device.18Wisconsin State Legislature. Wisconsin Code 343.305 – Chemical Tests for Intoxication After any OWI conviction, you must carry SR-22 proof of insurance for at least three years, which raises your premiums significantly.
Reporting a Crash
You must report a crash immediately to local police, the sheriff’s department, or a state traffic patrol officer by the quickest means available if the crash caused any injury, damage of $200 or more to government property, or total damage of $1,000 or more to any one person’s property.19Wisconsin State Legislature. Wisconsin Code 346.70 – Immediate Notice of Accident
Unless law enforcement files its own report, you must also file a written crash report with the Wisconsin Department of Transportation within 10 days, on the department’s approved form. If you cannot file, the duty passes to the vehicle’s owner, and then to any other capable occupant. Helping a driver flee the scene of a reportable crash is itself illegal unless the crash has already been reported.
Demerit Points and License Suspension
Wisconsin tracks moving violations through demerit points. Hit 12 or more points within 12 months and your license is suspended.20Wisconsin Department of Transportation. Wisconsin’s Point System Points track severity:21Wisconsin State Legislature. Wisconsin Administrative Code Trans 101.02 – Point Schedule
- 6 points for reckless driving, OWI, racing on a highway, speeding 20 mph or more over the limit, or fleeing an officer
- 4 points for speeding 11 to 19 mph over, failing to yield to an emergency vehicle, inattentive driving, or driving too fast for conditions
- 3 points for failing to signal, following too closely, improper turn, illegal passing, or failing to obey a traffic sign or signal
Driving While Suspended and Habitual Offender Status
Driving on a suspended license is a forfeiture of $50 to $200 for a basic violation. If someone is seriously injured during that drive, the penalty jumps to $5,000 to $7,500 with possible jail time, and if the underlying suspension was OWI-related, fines can reach $2,500 with up to a year in jail.22Wisconsin State Legislature. Wisconsin Code 343.44 – Penalty for Operating While Suspended or Revoked Driving without the required liability insurance is a separate offense under Wisconsin law.23Wisconsin State Legislature. Wisconsin Code 344.62 – Motor Vehicle Liability Insurance Required
Drivers who collect four major convictions, 12 minor convictions, or a combination totaling 12 within five years are classified as habitual traffic offenders and lose their driving privileges for a full five years. That revocation runs on top of the penalties for the individual violations, not in place of them.24Wisconsin Department of Transportation. Wisconsin’s Habitual Traffic Offender (HTO) Law
