Traffic in and out of Narrogin ground to a halt on Thursday after a serious crash west of town.
Two vehicles collided head-on at the intersection of Williams-Kondinin Road and Cooraminning Road about 2.50pm.
The Williams-Kondinin Road was closed in both directions after police and paramedics were called out to the crash scene.
The RAC rescue helicopter was deployed but was not needed.
A St John Ambulance spokeswoman said a man in his 30s was taken to Narrogin Health Service with a minor head injury.
The driver of the other vehicle walked away unscathed. Traffic on Williams-Kondinin Road was reopened but reduced to one lane as debris was cleared from the road.
