OZAUKEE COUNTY, Wis. (CBS 58) -- Friday, April 6 Wisconsin State Patrol will use aircraft and ground-based officers to check for speeders and lawbreakers along I-43.

The aircraft is scheduled for usage from 11 a.m. to 3 p.m. If conditions are not favorable for flying, ground officers will still be out in force.

The specially-equipped State Patrol aircraft use highway markings and a timing device known as VASCAR to determine if a car is speeding. When pilots detect speeders, aggressive or reckless drivers, they contact ground-based units to initiate a traffic stop.
