Lane splitting, sometimes referred to as lane filtering, lane sharing, or white lining, can be a controversial and confusing topic from state to state.

This page is designed to dispel some of the myths, present where you can do it, and how to do it safely.

What is Lane Splitting?

Lane splitting describes when motorcycles move between other traffic or in the same lane as other traffic when traffic is stopped or slowed considerably.

Since motorcycles are small and maneuverable, there is often plenty of space for them to move between cars when traffic is stopped.

Numerous studies and research since the permission of lane splitting in California have actually shown that it creates a safer environment for motorcyclists when done responsibly.

Lane splitting can:

  • Reduce traffic congestion.
  • Provide motorcyclists with more “escape routes.”

Filtering and lane splitting is common practice pretty much everywhere motorcycles and scooters are popular aside from the United States.

Tips for Lane Splitting Safely

In places where lane splitting is allowed, it is important to do it safely and responsibly.

Even if you’re lane splitting in a state where it is legal, the highway patrol can still ticket you for doing it unsafely.

Some tips for lane splitting safely include:

  • Only doing it when you have enough room.
  • Avoid lane splitting at high speeds.
  • Avoid riding excessively faster than stopped or slowed traffic when lane splitting.
  • Splitting between the far left lanes.
  • Not splitting next to large vehicles like trucks, buses, or RVs.
  • Keeping yourself visible.

If it can be done safely, lane splitting is a major benefit for motorists and other vehicles on the road.

However, it’s important to recognize the potential risks and hazards involved. As a motorcyclist, you’ll need to remember that you’ll be entering and exiting the blind spots of other drivers who may be frustrated sitting in traffic. Be alert, be respectful, and lane split responsibly.

Other vehicles have the responsibility to double check their mirrors and blind spots for motorcyclists before the try to change lanes or turn.
