Answer 2

A quick note,   the signs read  "....except to pass".     Totally different meaning.

The sign you ask about isn't for trucks,   but  for all drivers.     The idea is that if slower traffic keeps right,  there will be less weaving in and out  to pass.    Also,  slower traffic in the right lanes will make it easier for merging vehicles to enter the traffic flow,   and safer for those persons in all vehicles to exit as well.
