Cyclists can filter past stationary or slow-moving traffic by riding past the traffic queue, often using a space between lanes, as long as it's safe and legal to do so.
Here's a more detailed breakdown:
-
When Traffic is Stationary or Slow-Moving: Filtering is most common and beneficial when traffic is heavily congested or stopped completely.
-
When it is Safe: The primary consideration is safety. Cyclists must assess the situation and ensure they can filter without endangering themselves or other road users. This means:
- Checking for opening doors: Be aware of parked cars and potential door openings.
- Maintaining a safe speed: Don't filter too quickly; you need time to react to unexpected events.
- Being visible: Wear bright clothing and use lights, especially in low-light conditions.
- Anticipating driver behavior: Expect the unexpected and be prepared to stop or maneuver.
-
Legality: While filtering, or lane splitting, is generally accepted in many places, specific laws and regulations can vary greatly by jurisdiction. It is essential to be aware of, and adhere to, the local laws regarding bicycle operation.
- Check Local Laws: Before filtering, check your local or regional laws to make sure this is legal in your area. Not all jurisdictions allow cyclists to filter through traffic.
-
When it's Clear (Using the Oncoming Lane): As referenced, cyclists can filter past a traffic jam by crossing the dashed white line and riding in the oncoming lane, as long as it's clear. Any oncoming traffic has the right of way.
-
Examples of Good Filtering Opportunities:
- Slow-moving or stopped traffic at a red light: This is a common and often safe opportunity to move to the front of the queue.
- Congested city streets: Filtering can help cyclists avoid being stuck in gridlock.
-
Examples of Situations Where Filtering is NOT Advisable:
- High-speed traffic: Filtering in fast-moving traffic is extremely dangerous.
- Poor visibility (e.g., fog, rain): Reduced visibility increases the risk of accidents.
- Narrow lanes: Insufficient space makes filtering unsafe.
- Unfamiliar roads: Not knowing the road layout can lead to dangerous situations.
-
Considerations for Filtering:
- Road Conditions: Be mindful of potholes, debris, and other hazards.
- Weather Conditions: Rain, snow, or ice can significantly impact braking distance and handling.
- Traffic Flow: Constantly assess the movement of surrounding vehicles.
In conclusion, cyclists can filter when traffic is slow or stationary, when it's safe to do so, and when legal according to local regulations. Prioritize safety and always be aware of your surroundings.
