How to Fight a Parking Ticket in Mequon, WI

The no-parking sign was absent, missing from the block, obstructed by a tree or another sign, or so faded as to be illegible at the time of the violation.

Legal basis:

A motorist cannot be held responsible for violating a regulation that was not properly posted. Signage must be installed and maintained according to the Manual on Uniform Traffic Control Devices (MUTCD).

Required evidence:

• Photograph of the sign (or lack thereof) taken on or near the violation date
• Wide-angle photo showing the full block face
• Timestamp metadata from the photo

The parking meter was visibly broken, displayed an error, accepted payment but failed to register it, or was not functioning at the time the vehicle was parked.

Legal basis:

Vehicle operators are not required to seek alternative parking when a meter malfunctions. The city bears responsibility for maintaining meter equipment.

Required evidence:

• Photograph of the meter display showing the error or malfunction
• Receipt or bank statement showing payment attempt if applicable
• Timestamp from the photograph

Two or more signs on the block face or pole provided contradictory parking rules, making it impossible to determine the lawful parking restriction.

Legal basis:

Contradictory signs create an ambiguity that must be resolved in the motorist's favor. Enforcement cannot stand when the regulation is unclear.

Required evidence:

• Photograph clearly showing both conflicting signs in the same frame
• Photograph showing the distance between the signs

The ticket contains a material error in the vehicle description — wrong license plate number, incorrect state, wrong vehicle make, model, or color.

Legal basis:

A ticket with a materially incorrect vehicle description is legally defective. The issuing officer must accurately identify the vehicle for the citation to be valid.

Required evidence:

• Copy of vehicle registration showing correct plate and description
• Photograph of the vehicle's actual license plate

The vehicle was parked in violation because of an unforeseen medical emergency affecting the driver or a passenger that required immediate attention.

Legal basis:

Most municipal codes recognize medical necessity as an affirmative defense to a parking violation. The emergency must be genuine and documented.

Required evidence:

• Hospital or emergency room discharge paperwork showing date and time
• Doctor's note or urgent care visit documentation
• Any emergency services record

The parking restriction was not properly posted under Wis. Stat. § 349.13, or the citation omitted information required under Wis. Stat. § 345.11 for a valid citation.

Legal basis:

Wis. Stat. § 349.13 requires local ordinances to authorize parking restrictions with proper signage before enforcement. Wis. Stat. § 345.11 specifies required citation content; material defects may support dismissal.

Required evidence:

• Photograph of the sign or its absence at the cited location
• Copy of the citation showing missing or incorrect required fields

Mequon has extensive rural and semi-rural roads where parking restriction signs may be sparse or absent. If the citation was issued on a road without clear posted restriction signage, the lack of signage is a strong defense.

Legal basis:

Wis. Stat. § 349.13 requires parking restrictions to be established by ordinance and marked with proper signage before they are enforceable. A restriction with no posted signs cannot be enforced against a motorist.

Required evidence:

• Photograph of the cited location and surrounding block face showing no restriction signs
• Google Street View or dated photographs confirming the absence of signage near the violation date
