There's nuance between lane-splitting and lane-filtering, though most don't know that. Lane-splitting is what most folks know and they can easily call to mind how they've seen or witnessed first-hand a motorcycle slicing through bumper-to-bumper traffic at low speeds and making their way to their final destination while the cars around move slowly.
Lane-filtering, however, is when every car is stationary and waiting at a stop light, and motorcyclists are allowed to filter through the traffic to the light itself, thereby reducing their exposure to possible rear-ends. But the cars not moving is the difference between the two.
Utah, my home state, allows lane-filtering. It does not allow lane-splitting, and a recent law passed last year not only makes it a crime to lane-split, but it also makes a wheelie a crime, too. Here's what you need to know.
