ACT Motorcycle Lane Filtering

The ACT Government initiated a two-year trial of lane filtering, which commenced on 1 February 2015 and concluded on 31 January 2017. Following a positive evaluation of the trial, lane filtering was introduced permanently in the ACT.

What is lane filtering?

Motorcycle lane filtering is when a motorcycle is riding between two marked lanes with the same direction of travel as the motorcycle when there are stationary or slow moving vehicles next to the motorcycle in both marked lanes.  

Motorcycle lane filtering in the ACT

Lane filtering is:

  • only allowed when safe to do so;

  • not allowed at a speed greater than 30km/h;

  • only allowed by fully licensed motorcyclists (ie. learner and provisional licensed motorcyclists are not allowed to lane filter);

  • not allowed on the kerbside next to a footpath or in bicycle lanes or breakdown lanes;

  • not allowed in ANY 40km/h zones (such as school zones, roadworks and city centres); and

  • not allowed past heavy vehicles and buses.

Motorcycle lane filtering is not the same as lane splitting. Lane splitting involves higher speeds (above 30km/h), which increases the unpredictability of motorcyclist movements for other road users. Lane splitting is not permitted in the ACT.
