Ans. When it's an "Advisory Treatment".
Call me naive and gullible, but I always considered that when there was a painted line separating cars and bicycles with bicycles stencils painted at regular intervals along the bicycle side of the line, that this was a designated bicycle lane. Not so.
On my way home today, I stopped to take some photos of the road works on Walkerville Terrace and I guy form the Department of Transport in a suit (as opposed to the guys in orange vests), introduces himself and proceeded to explain what was happening which was both very helpful and enlightening.
It turns out that in order to widen the footpaths (which were not particularly narrow), the council is removing the existing bicycle lane and replacing it with a narrower "Advisory Treatment", which will allow them to claim they are still providing cycling infrastructure.
So what is an "Advisory Treatment". It can look like a bike lane with bicycles painted along it, but there are no "bike lane" signs and it provides no legal separation of bicycles and other vehicles. Cyclists are not required by law to ride in the area defined by the "Advisory Treatment". however no doubt most will anyway, not realizing it is not a bicycle lane and in doing so put themselves at risk of being car doored. Of course should a cyclist opt to outside the area of the "Advisory Treatment" to avoid being car doored, motorist will get jacked off with the for not riding n the "bike lane"
The Walkerville council is creating a major hazard for cyclists along Walkerville Terrace with cyclist accidents almost certain to result.
