At 5:30 a KMZU listener called in an apparent roll-over accident on west 50 highway in Warrensburg.  The caller did say that State Troopers were on scene and a tow truck was taking the vehicle from the site at that time, but traffic remained heavy still at 5:40.  If that highway is part of your normal route, it is advised to find an alternate direction to take.  If a different route is not available, please use caution in that area.
