Official assisted me to get sleepy truck driver off the road

N1 South, 10km before Kroonvaal A truck almost drove me off the road and I hooted and he sverved to the other side over the yellow line. I drove a few km and found Metro Police officers on the side of the road and stopped and asked if they could please pull over the truck as I suspected the driver was tired. We waited and the Officer pulled the truck over, spoke to the driver, came back nd told me that the driver is overtired and they will force him to sleep before he is allowed to drive. I also had the opportunity to plead with the driver to sleep as I have a family who is waiting for me at home. I appreciate the work the Officer was doing to assist me.
