Previously, filtering, or lanesplitting has been illegal in all of Australia. This is a rare case where the formerly illegal practice has been made legal for safety and congestion-relief concerns.
NSW has defined filtering as legal as long as done at under 30 kph. They define lanesplitting as illegal, as that is the term that they have defined for splitting lanes at over 30 kph. In the United States, however, the terms are virtually synonymous, and to do it legally, in California, for example, must simply be done in a safe manner.
