Seriously??redned wrote:I can't find any reference to 25% and in fact the example in the code that you cite is 75% less than the speed limit. And "abnormally slow" will relate to what is "normal" for the vehicle itself. 20kph is not abnormally slow for a bicycle.
Ok I will bite, the example states traveling 20km/hr in a 80km/hr zone would be considered "abnormally slow" for that road (irrespective of vehicle). 20km/hr = 25% of 80km/hr therefore if you are travelling at 25% or less of a stated max speed limit you could be considered to be causing an obstruction without good reason (good reasons = hazards, traffic congestion etc.).
"Abnormally slow" applies to the road if you can't achieve it and you don't have a good reason then you are considered to be committing an offence.
