Lane splitting

Lane splitting is riding a bicycle or motorcycle between lanes or rows of slow moving or stopped traffic moving in the same direction. It is sometimes called whitelining, or stripe-riding. This allows riders to save time, bypassing traffic congestion, and may also be safer than stopping behind stationary vehicles.

Filtering or filtering forward is to be contrasted with lane splitting. Lane filtering refers to motorcycles moving through traffic that is stopped, such as at a red traffic light.
