I'm not sure what the law states but it's pretty much universal to pull to the side of the road when making a turn, including using the shoulder to enter a store or take an exit on the highway. Similar to crossing a yellow line and momentarily driving on the opposite side of the road to get around obstructions.12.3.4 regression: did NOT move R into the breakdown lane while slowing to make a R turn to give followers more room to pass (which they will no matter what). May be more legal but certainly less customary and not as safe.
Have sub-versions of v12 been making use of the shoulder like this? I've never known v11 to do so.
