Filtering on a bicycle, often referred to as lane splitting or white-lining, involves moving through slow or stopped traffic. A specific method for navigating traffic jams when space is limited is detailed below, based on the provided reference.
When traffic is stopped and there isn't sufficient room to filter between vehicles, the approach changes. According to the provided guidance:
If there's isn't a bike length between vehicles, stop behind and off to one side of the vehicle in front. Eyeball the driver behind, and if necessary signal your intent to move back into the traffic stream. When the traffic starts moving, take the lane.
This describes a particular strategy for positioning yourself and rejoining the traffic flow when traditional filtering through tight gaps is not feasible.
Filtering When Space is Limited
If you encounter traffic where the gaps between vehicles are less than a bike length, filtering between them is not recommended for safety reasons. Instead, follow this method:
- Stop Position: Rather than attempting to squeeze between cars, stop behind the last vehicle in the queue. Position yourself off to one side of the vehicle directly in front of you (the one you stopped behind). This allows you to be visible and prepares you to move alongside.
- Communicate with Drivers: As you position yourself, make eye contact ("eyeball") with the driver behind you. This acknowledges their presence. If you plan to move back into the main traffic lane (e.g., slightly in front of the car you are beside) before traffic starts moving, signal your intention.
- Rejoin Traffic Flow: Once traffic begins to move again, smoothly merge into the main lane ahead of the vehicle you were positioned beside. The guidance specifically states, "When the traffic starts moving, take the lane."
This maneuver allows you to advance past the stopped queue without attempting dangerous filtering through insufficient space.
Important Considerations
- Legality: Filtering/lane splitting laws vary significantly by location. Always check the specific traffic laws in your area regarding bicyclist conduct around vehicles. This description outlines a specific maneuver, but its legality and appropriate context depend on local regulations.
- Visibility: Always prioritize being visible to drivers. Positioning off to the side, making eye contact, and signaling are crucial for safety.
- Judgment: Use your best judgment. If a situation feels unsafe, wait for traffic to clear or find an alternative route.
This method, as described in the reference, provides a structured way to handle stopped traffic when the space between vehicles is too tight for conventional filtering.
