NSW introduced the concept of penalty levels in 2005, ie levels 1 to 17

Penalty levels were subdivided in 2010 with 34 levels ie 1 and 1a etc

There are a number of offences, they are not all listed below. The additional offences were the result of a tragic incident and were a knee jerk reaction to the incident rather than apply other existing offences.

All 3 offences are the same $ value but only 270(1)(a) and 270(1)(b) are demerit point offences.

Offence descriptions and meanings have become distorted over time. Originally the descriptions and details were included in the road rules or traffic acts and so the meanings were clear.

The volume of offences and the number of officials who needed access to the information increased and so the penalties and descriptions were moved to separate legislation and the practice of using "short descriptions" in the penalty legislation began.

This now means the infringement notices as issued may mean other than what they state. The offence and penalty legislation have clauses which state in effect that the short description means the same as the long description contained in the regulations.
