A Sharrow Designates A Traffic Lane That Is

Unveiling the Secrets of the Sharrow: A Safe Haven for Cyclists

Picture this: you’re cruising along a bustling city street on your bike, surrounded by a sea of cars. Suddenly, you come to a junction and hesitate – where do you go? This is where the enigmatic sharrow steps in, offering guidance and safety in the urban jungle.

Often overlooked but essential for cyclists, a sharrow is a traffic lane that is designated for shared use by both cars and bikes. It’s a symbol of harmony on the road, indicating that cyclists have a rightful place alongside motorized vehicles. By clearly defining the boundaries of the bike lane, sharrows reduce the risk of conflicts and accidents, making our streets a more hospitable environment for all.

Understanding the sharrow’s purpose is crucial for both cyclists and drivers. For cyclists, it provides a clear and dedicated path, allowing them to navigate traffic with confidence and ease. Drivers, on the other hand, are reminded to share the road responsibly and be mindful of cyclists’ presence. Together, this harmonious coexistence ensures a safer and more efficient flow of traffic for everyone.

A Comprehensive Guide to Shared Lane Markings (Sharrows)

Shared lanes, commonly designated by a sharrow, are traffic lanes designed to accommodate both cyclists and vehicles. This innovative approach to road design enhances safety and promotes cycling as a transportation option. Here’s an in-depth exploration of sharrows, their benefits, and guidelines for usage.

What is a Sharrow?

A sharrow is a pavement marking—a stencil or thermoplastic symbol—that resembles a bicycle with two arrows pointing in the same direction. It signifies a shared lane where cyclists and vehicles coexist.

Benefits of Sharrows

Sharrows provide several advantages:

  • Increased Safety: They alert drivers to the presence of cyclists, reducing the risk of conflicts and collisions.
  • Enhanced Visibility: By designating a specific lane for cyclists, sharrows make them more visible to motorists.
  • Promotes Cycling: Sharrows encourage cycling by providing a safe and accessible infrastructure for cyclists.
  • Reduces Traffic Congestion: Shifting cyclists to shared lanes can free up vehicle lanes, potentially reducing traffic congestion.

Guidelines for Using Sharrows

Sharrows are typically used in the following scenarios:

  • Low-traffic roads: Where traffic speeds are typically below 35 mph.
  • Bike-friendly areas: Neighborhoods, campus areas, and commercial districts with a significant cycling population.
  • Transition zones: Where dedicated bike lanes connect to intersections without bike lanes.

Cyclists should observe the following guidelines when riding in shared lanes:

  • Ride Predictably: Stay in the center of the lane and signal your intentions clearly.
  • Be Aware of Surrounding Traffic: Pay attention to vehicles approaching from behind and anticipate potential conflicts.
  • Yield to Pedestrians: Always slow down or stop when encountering pedestrians crossing or walking in the shared lane.

Transitioning Between Lanes

Sharrows often mark the transition between dedicated bike lanes and shared lanes. Here’s how to navigate these transitions safely:

  • Merge Gradually: Gradually move into the shared lane from the bike lane.
  • Check for Traffic: Before merging, check for any approaching vehicles or cyclists.
  • Signal Your Intention: Use hand signals or turn signals to indicate your intention to merge.

Enforcement of Sharrows

Enforcement of sharrows varies by jurisdiction. Some localities treat them as enforceable regulations, while others primarily use them as advisory markings. However, motorists should generally be aware of sharrows and give cyclists ample room to maneuver.

Addressing Common Misconceptions

Myth: Sharrows give cyclists the right to obstruct traffic.
Fact: Sharrows do not confer any special rights or privileges to cyclists. They simply indicate a shared lane.

Myth: Cyclists must always ride in the center of a shared lane.
Fact: Cyclists should ride in the center of the lane for visibility but may move to the side when necessary, such as to avoid obstacles or oncoming traffic.


Sharrows are an effective tool for promoting cycling safety and accessibility. When used in appropriate locations and with adherence to guidelines, they can create a more harmonious and equitable road environment that benefits all users. By embracing shared lanes, we can encourage cycling, reduce traffic congestion, and create more vibrant and sustainable communities.


  1. Are sharrows always present at intersections?
    No, sharrows may not always be present at intersections, especially where dedicated bike lanes exist or where the presence of a bike lane is evident.

  2. Do sharrows apply to motorcycles as well?
    Yes, sharrows apply to all two-wheeled vehicles, including motorcycles.

  3. Can sharrows be installed on roads with high traffic speeds?
    Generally, sharrows are not recommended for roads with traffic speeds above 35 mph.

  4. What other markings or signs may be used in conjunction with sharrows?
    Supplemental markings or signs may include bike symbols, directional arrows, and pavement messages that reinforce the shared lane designation.

  5. How can I report improper usage or obstruction of a shared lane?
    Report any incidents of obstruction or improper usage to the appropriate local authorities, such as the police department or traffic safety agency.
