What is the fine for running a red light in Wisconsin?
Under Wis. Stat. § 346.37, the base forfeiture for a first red light violation within a year is $20 to $40. For a second or subsequent conviction within a year, the forfeiture is $50 to $100. Mandatory court surcharges substantially increase the total — a $30 base forfeiture with standard surcharges can result in a total payment near or above $100. Verify the exact total with your specific court. Violations in school zones or highway maintenance/construction zones may carry enhanced forfeitures.
How many points does a red light ticket add in Wisconsin?
A red light (failure to obey traffic control signal) conviction under Wis. Stat. § 346.37 adds 3 demerit points to your Wisconsin driving record. Drivers with probationary licenses or instruction permits receive 6 points (double). The 3-point reduction from completing the Wisconsin Traffic Safety Course can fully offset the points from a red light ticket.
Can I contest a red light ticket in Wisconsin?
Yes. You may plead not guilty at your initial court appearance and proceed to a pretrial conference or trial. Common defense angles include: (1) the yellow light entry defense — you entered the intersection on yellow before it turned red; (2) signal timing challenge — request the signal timing data to verify the yellow phase met engineering standards; (3) officer observation — cross-examine on the officer's exact vantage point, distance, and line of sight to the intersection; (4) 'clear, satisfactory, and convincing' standard — the state must prove by more than a preponderance that the light was red when you entered. A jury trial is also available if requested in writing within 10 days of the initial appearance.
What is the standard of proof for a red light ticket in Wisconsin?
Under Wis. Stat. § 345.38, the state must prove the red light violation by 'clear, satisfactory, and convincing evidence' — higher than the preponderance standard used in typical civil cases, but lower than beyond a reasonable doubt. For the state to meet this standard, the officer's testimony that the light was red must clearly and convincingly establish the fact. Ambiguity about whether you entered on late yellow vs. early red, or questions about the officer's vantage point, can prevent the state from meeting this elevated standard.
How do I challenge the signal timing evidence in court?
Signal timing data — including the duration of the yellow phase and any all-red clearance interval — is typically maintained by the city or municipality that owns the traffic signal. You may request this data through a public records request to the relevant city traffic engineering department. Engineering standards for yellow phase duration are based on the speed limit of the roadway (higher speed limits require longer yellow phases under the ITE formula). If the yellow phase was shorter than the engineering standard, it raises a serious question about whether drivers had adequate time to stop safely.
Does Wisconsin use red light cameras?
NOT CONFIRMED — Wisconsin law allows municipalities to adopt red light camera programs, but statewide adoption is not uniform. Some Wisconsin cities may have active red light camera programs. If your citation was issued by a camera rather than an officer, review the citation carefully for the specific enforcement mechanism and contact your local court for procedures regarding camera citations. This guide primarily addresses officer-issued citations. Verify current camera program status with your specific municipality.
What happens if I pay my red light ticket without contesting?
Paying the forfeiture without contesting is treated as a guilty plea. Three demerit points are assessed, the conviction is recorded on your driving record, and it may be reported to your insurer. You permanently waive your right to contest the violation. For drivers on probationary licenses, 6 points are assessed (double). Appearing in court preserves your ability to challenge the state's evidence or present mitigating circumstances.
Does a red light ticket affect my insurance in Wisconsin?
A red light conviction is reported to your insurer and may increase your premiums. The increase varies by insurer and your prior record. The 3-point reduction from the Traffic Safety Course reduces your DMV record points but does not remove the conviction from insurer records. Contesting the ticket and achieving a not-guilty verdict, or negotiating to a non-moving violation, is the most effective way to protect your insurance rate.
Can the Traffic Safety Course help offset red light ticket points?
Yes. The Wisconsin Traffic Safety Course (12-hour program) reduces your demerit point total by 3 points — which fully offsets the 3-point impact of a red light conviction. You must notify the DMV within 30 days of completing the course. The course can only be used once every 3 years. It does not remove the conviction from your record, but it prevents the points from pushing you toward the 12-point suspension threshold.
What are the rules for a yellow light in Wisconsin?
Under Wis. Stat. § 346.37, a yellow (caution) signal means that a red signal is about to appear and drivers should stop if they can do so safely, or clear the intersection if stopping is not safe. There is no absolute prohibition on entering an intersection during a yellow light. If you entered the intersection while the light was yellow — even if it turned red after you entered — you did not run the red light. The key factual question is what color the light was at the exact moment you entered the intersection, not what color it was while you were in the intersection.
