Wausau (WAOW)-- Truck driver policies are under the microscope as Michael Haydon's trial continues into day four.
Haydon is accused of killing Patrick Zemke in 2003.
Zemke was a Kolbe and Kolbe truck driver.
Conrad Waldner, one of Zemke's fellow drivers testifies he saw Zemke's truck on the side of the road the day of the murder. He says it wasn't out of the ordinary for the truck to be parked because that's how drivers would rest if their deliveries took less than ten hours.
Jason Mork, Director of Transportation at Kolbe and Kolbe told the court that since this incident policies have been changed and drivers are no longer allowed to sleep in their trucks.
The trial continues tomorrow and could go as long as another two weeks.
