So, you're driving on a 3-lane motorway, middle of the night and nothing around. Then you come across a nobhead in the middle lane, overtaking no-one. Do you stay in your lane, effectively undertaking, as the hazard is not in your lane so there is no need to alter course, or do you have to pull out to the outside line, overtake, then move back to the inside lane, no doubt swearing and gesturing profusely?
I'm not sure of the legality of this, and have performed both manoeuvers...
