That is what I was taught id drivers ed!!!!
Slower traffic always moves right, reguardless of your speed.
Most young people here ignore it and I have seen them get stopped.
Yup. I was taught (rightfully so) to move over for ANY vehicle on the highway shoulder, if possible. 35 years ago. NY has the move over law for emergency, DOT, and wreckers.
If you have ever sat in a car on the shoulder of a highway and experienced people blowing past at 70+ miles an hour, you'll understand quickly why this makes sense.
