The Nevada Highway Patrol (NHP) is investigating multiple rollover crashes along I-80 on Thursday.

They said four separate crashes involved commercial vehicles and three of them occurred between Fernley and Lovelock and the 4th near Carlin.

As of 6 p.m., NHP says all four are cleaned up.

They said none of the crashes were weather related and all were due to driver error, because they did not find evidence of mechanical failure.

NHP said there were no serious injuries.
