Lane Splitting is used to describe moving through traffic that is in motion.
Lane Filtering is used to describe moving through traffic that is stopped.
Depending on where you live, this practice may or may not be legal. Australia is an example that is a country that each state differs in it’s Law.
Lane Splitting/Filtering is an unsafe practice which usually contravenes the road rules.
While the Australian Road Rules and WA Road Traffic Code 2000 do not explicitly ban Lane Splitting/Filtering, they do prohibit the practice by virtue of the fact that a number of other rules may be and are regularly contravened during the manoeuvres, such as not signalling before a lane change, riding with the wheels on the lane line, crossing continuous lane lines, safe overtaking and so on.

A Video that explains why Motorcyclists Split Lanes
Filmed in the USA, about Lane Splitting/Filtering.
My Comment: This video has highlighted an important point, US States that allow Lane Filtering have statistically lower rates of vehicles “rear ending” motorcycles. Remember, statistics are not just numbers, they are real lives saved!
If neither Lane Splitting or Lane Filtering is illegal in your country, depending on the police officer that pulls you over, you may be fined if you:
Two Lanes at Once
Put your foot down in another lane than the lane your bike is in.
Cross Continuous Line
Cross over the continuous white line at the intersection.
Protrude Stop Line
Place your front tyre beyond the stop line.
Travel over the lane dividing line (change lanes) without indicating.
Overtake on the Left
Travel between traffic while it is moving, (Lane Splitting), because you are overtaking on the left of another vehicle, while it is not turning right or performing a u-turn (or opposite in the US).
