My state too allows for vehicles to pass cyclists on a solid yellow when it can be assertained that nothing is coming the other way. Big difference in how much room is needed to pass something moving at less than 25 mph than another vehicle moving at 50 mph or better. I'm sure you are well aware of that, but I included that for the masses.
Not sure why this same thing doesn't apply for when passing other slow moving vehicles. Maybe it does and I've just not noticed.
The reference I saw said SC made this clear in 2016, but it wasn't any more specific than that. SC law is that a driver can cross a solid center line if the oncoming lane is clear IF the right lane is obstructed and passing a bike requires 3 foot clearance, so I think that the regulation may be that a bike in the lane is considered an obstruction for that purpose.
