On my way home yesterday I was going north on I44. Traffic started backing up about halfway between SW 44Th and SW 29Th. The reason ended up being that the OHP was checking vehicles/drivers at the 29Th entrance ramps. Southbound traffic was way worse and I counted two rear enders caused by the backup. Now, is catching a few expired license, expired insurance, etc. worth creating a hazard. I know the cause of the accidents was the drivers themselves. But the situation setting up the backup was OHPs doing.
