June 3, 2021 Driving East this morning going through a construction zone truck 691 came barreling up the hill. It tried to get past us vehicles in the left lane but had to slow down. Truck was probably doing 80mph at least once it got past us by sully exit on I-80 . A few miles ahead a state patrol car was in median keeping speed it slowed down real fast and it kept swerving all over the road for a grain truck as my wife said he must be empty. About Amanda colonies there was another semi that was carrying a truck on the flat so the outlaw express truck 691 truck again decided to play keep up with the leader so he decided to tailgate us again until we moved over. Glad I was only driving to Iowa city from Des Moines. What is to say this driver would of caused an accident past Iowa city unknown....
