Driven that highway hundreds of times in the winter they really don't like to take care them either.
Far as I'm concern anyone stranded on the side of the road you should move over.
The way I was taught is you slow the truck down to 1000 to 1300 rpm double clutch in neutral rev it up about 1400 to 1600 rpm to match truck speed...
I don't see why it's hard to move over when someone on the side of the road.
