State Patrol plans aerial enforcement in several counties over the next two weeks

Release date: March 14, 2019​

To enhance safety for all travelers, the Wisconsin State Patrol plans to use aircraft and ground-based officers to enforce speed limits and other traffic laws in three southeast Wisconsin counties over the next two weeks. If weather conditions are unfavorable for flying, the enforcement efforts typically proceed using ground-based units. The aerial enforcement missions are scheduled for:

  • Thursday, March 14 along I-43 in Walworth County

  • Friday, March 15 along I-39/90/94 in Columbia County

  • Thursday, March 21 along I-94 in Jefferson County

  • Sunday, March 24 along US 41 in Marinette and Oconto counties

  • Monday, March 25 along I-43 in Ozaukee County

“At the State Patrol, public safety is our primary mission,” Lieutenant Chris Jushka, who oversees the State Patrol’s Air Support Unit said. “Speeders and other aggressive drivers risk much more than a citation – they endanger the safety of everyone along our roadways.” In 2018 in Wisconsin, there were nearly 20,000 speed-related crashes resulting in 7,957 injuries and 173 fatalities - that’s higher than the number of people injured (3,278) and killed (159) in alcohol-related crashes.

The Wisconsin Department of Transportation publicly announces many enforcement efforts to reinforce that the goal is voluntary compliance with traffic laws - not to stop or cite motorists. Most State Patrol aerial missions are made possible through federal funds specifically designated to support traffic law enforcement. The State Patrol analyzes data on traffic citations, crash reports and related information to identify specific highway corridors for enforcement initiatives.

State Patrol aircraft use a timing device known as VASCAR (Visual Average Speed Computer and Recorder) along with highway markings to determine vehicle speeds. When pilots detect speeders, aggressive or reckless drivers, they contact ground-based units to initiate a traffic stop. A WisDOT YouTube video highlights the role of the State Patrol’s Air Support Unit.
