A points system to penalise law-breaking drivers that was introduced in October is in full-effect in Magistrates' Court.

Poor driving and habitual road-rules offenders can now expect on top of fines, to accumulate demerits — and 12 of these in a two-year span can disqualify the drivers from the road.

Under the new system people who fail to stop at a stop sign will run the risk of getting two to four points while people speeding could get as many as seven points for one offence.

Meanwhile towing someone on roller skates and "unlawful sounding of warning device" could get you two to four points.

The legislation was passed in 2005 and all points will expire two years after the date of the original conviction.

When the legislation was introduced Premier Ewart Brown said the purpose of the system was two-fold: "First, it monitors the development of poor driving records in newly licensed drivers and takes steps to improve their driving habits. Second, it protects the public from habitual offenders by disqualifying or revoking the licences of unsafe drivers."
