In early 2009, when I was a very fresh, new member of Parliament, I was a member of what was known then as the Transport and Industrial Relations Committee, and the first bill that brought the roadside impairment test regime in was being considered by that committee. One of the senior members on that committee, the Hon Trevor Mallard, on the day that New Zealand Police came in to demonstrate the roadside impairment test and how it would be carried out, decided that the newest member of the committee should actually embark on that test. So in the middle of the select committee room 4, in front of the media and a number of officials, I actually walked the line, touched my toes, turned around, did all of the things that needed to be done on a roadside impairment test and found that it was actually pretty difficult to pass even when one was not impaired by any substance.
