I am not going to try to look it up but I know this is correct. I've lived in the mountains & anybody that does or has knows this. If you have 5 or more vehicles behind you, you are required to pull over at the very next available turnout. This holds true with bikes also for the reason UK posted. By law you are not required to do so if the number is less than 5, but if they have been behind you for several miles it might be actually safer to do this anyway. Plus it is courteous. You may have to slow down for a bit to do so safely but the drivers would probably prefer that than to remain behind you indefinitely.
