I was always under the impression that on a “normal" 4 exit roundabout (i.e. two roads crossing), you would indicate left if going left, right if going right, and no indication if going straight on. Then whichever way you’re going you indicate left when passing the exit before. However, a number of drivers indicate right when going straight on, which means I stop expecting them to continue around but could’ve entered the roundabout. Am I incorrect here? Was there a time when something different was taught?
One of us is misreading 186, or I’m misreading your comment.
To me, 186 says to stay in the right hand lane for turning right or full circle, and then for all other exits apart from the first you should:
"When taking any intermediate exit (unless signs or markings indicate otherwise):
There are three sections under 186, first exit, right/full circle, and intermediate exits (which at a four lane would include straight)
