Wisconsin code on reasonable and prudent speed

Maximum speed law:

According to section 346.57(2) of WI vehicle code, “No person may drive a vehicle at a speed greater than is reasonable and prudent under the conditions and having regard for the actual and potential hazards then existing.”

Minimum speed law:

Section 346.59(1) and 346.05(3) states:

“No person shall drive a motor vehicle at a speed so slowly as to impede the normal and reasonable movement of traffic.”

“A person driving at less than the normal speed of traffic shall drive in the right-hand lane then available for traffic or as close as practicable to the right-hand curb or edge of the roadway.”

Due to variations in speedometer calibration, tire size, and margins of error in speed-detecting technology, it’s uncommon for an officer to pull a driver over for going less than five miles above the speed limit. However, technically any amount over can be considered a speed violation so best practices are to stay within the limit.

While it may be difficult to fight a speeding ticket in Wisconsin due to the absolute speed limit law, a driver may choose to go to court and claim their innocence based upon one of the following:

  • The driver may oppose the determination of speed. In order to claim this defense a driver must know how his or her speed was determined and then learn how to disprove its accuracy.

  • A driver may claim that an emergency situation caused the driver to break the speed limit in order to prevent injury or damage to themselves or others.

  • The driver may claim a case of mistaken identity. If a police officer clocks a driver speeding and subsequently has to find them again in traffic, it’s possible that they could have made a mistake and pulled the wrong car over.
