(1) Make a lane change into an available lane not immediately adjacent to the authorized emergency vehicle or tow truck with due regard for safety and traffic conditions, if practicable and not prohibited by law.
(2) If the maneuver described in paragraph (1) would be unsafe or impracticable, slow to a reasonable and prudent speed that is safe for existing weather, road, and vehicular or pedestrian traffic conditions.
I knew of the law, but just read the second paragraph. Seems a little vague, no?
