Bicycle Dooring Accidents in Protected Lanes: Suing the City When Parking Design Created the Hazard

Caleb Bland Law, PLLC June 10, 2026

If a parked vehicle’s door struck you while you were riding in a protected bicycle lane, the person who opened the door may be responsible. A claim against the city is more difficult. Municipal liability may depend on who controlled the roadway, whether governmental immunity applies, how the lane was designed or maintained, and whether the parking configuration contributed to the collision.

At Caleb Bland Law, PLLC, we help injured cyclists determine who may be liable, preserve evidence, and pursue compensation for their injuries. Our personal injury attorneys serve Elizabethtown, Radcliff, Shepherdsville, Bardstown, Brandenburg, Leitchfield, Hodgenville, Louisville, and surrounding Kentucky communities. Contact us today.

How Parking Design Can Place Cyclists in the Door Zone

Protected bicycle lanes are intended to separate cyclists from moving vehicles. Some designs place the bike lane between the curb and the passenger side of parallel-parked vehicles. Without sufficient space between the parking area and the bike lane, cyclists may be forced to ride within the range of an opening door.

A narrow lane or inadequate buffer does not automatically establish negligence. Evaluating the design may require examining lane measurements, parking arrangements, sight lines, approved plans, traffic studies, and the engineering standards or design guidance used for the project. The investigation should also determine whether the lane’s condition differed from its approved design because barriers, markings, signs, or other features were installed incorrectly or poorly maintained.

After a bicycle accident, we review the physical configuration of the street and identify the public agency or contractor responsible for designing, installing, and maintaining the bicycle lane. This information can help distinguish a protected governmental planning decision from negligent implementation or maintenance.

When Can a City Be Liable for a Dooring Accident?

The person who opened the vehicle door may be liable if they failed to check for approaching cyclists or otherwise use reasonable care. Depending on the facts, responsibility may also extend to a vehicle owner, contractor, or governmental entity. Multiple parties may share fault for the same accident.

Holding a Kentucky city liable presents additional legal issues. State law generally protects local governments from claims arising from legislative authority, policy decisions, resource allocation, and other exercises of judgment or discretion. That protection may apply to some roadway-planning and bicycle-lane design decisions. However, negligence by government employees while carrying out ministerial duties may receive different treatment.

A successful claim therefore requires more than showing that the bicycle lane was hazardous. The evidence must support a legally recognized claim that is not barred by immunity and connect the responsible party’s conduct to your injuries. Relevant questions may include:

  • Who owned and controlled the roadway?

  • Who approved and installed the parking and bicycle-lane configuration?

  • Did the completed lane conform to its approved plans?

  • Was the city aware of previous crashes, complaints, or reported hazards?

  • Did poor maintenance or an unauthorized change make the lane more dangerous?

  • Was the street controlled by a city, county, state agency, or private contractor?

We investigate these issues before determining whether a claim against the city or another entity may be available.

Evidence Used to Evaluate Municipal Liability

Claims involving street design require different evidence from an ordinary motor vehicle claim. The city may argue that its decisions are protected by immunity, that the person opening the door caused the entire accident, or that you could have avoided the collision. Preserving evidence can help establish how the physical layout affected your ability to respond.

Important evidence may include:

  • Lane and buffer measurements: Measurements can show how much room existed between parked vehicles, the bicycle lane, and the curb or barrier.

  • Design and approval records: Engineering plans, contracts, meeting records, and adopted design criteria may identify who made or implemented the relevant decisions.

  • Parking conditions: Delivery areas, medical facilities, retail businesses, and other high-turnover locations may affect how frequently doors open beside the lane.

  • Previous reports: Earlier collisions, complaints, maintenance requests, or safety studies may show that the responsible agency knew about the condition.

  • Photographs and video: Images of the vehicle, open door, lane markings, barriers, signs, and surrounding street can document conditions before they change.

  • Witness accounts: Drivers, passengers, pedestrians, and other cyclists may provide firsthand accounts of how the door opened and whether you had enough time or space to avoid the collision.

  • Professional analysis: A traffic engineer or other qualified professional may be needed to evaluate the plans, measurements, installation, and role of the roadway configuration.

We can request public records, inspect the crash location, preserve available recordings, and consult appropriate professionals when technical review is warranted.

What Should You Do After a Protected-Lane Dooring Accident?

Call law enforcement and seek medical attention after the collision. Some injuries may not be immediately apparent, and prompt treatment creates a record connecting your condition to the crash. If you can do so safely, photograph the open door, parked vehicle, bicycle lane, buffer, barriers, signs, road markings, and your bicycle before anything is moved.

Obtain the names and contact information of witnesses. Preserve your bicycle, helmet, clothing, and damaged equipment without repairing or discarding them. Keep copies of medical bills, wage records, correspondence, and other documents showing how the accident has affected you.

Act promptly when a city may be involved. Kentucky law can require notice to specified city officials within 90 days for certain injury claims arising from a defect in a public thoroughfare. Separate filing deadlines may also apply, and the involvement of a motor vehicle can affect the limitations analysis. You should not assume that an ordinary personal injury deadline is the only time restriction governing your claim.

Avoid signing a release or giving a detailed recorded statement before you know which parties and insurance policies may be involved. An early settlement with one party could affect claims against others.

How Our Personal Injury Attorneys Can Help

At Caleb Bland Law, PLLC, our attorneys examine both the immediate cause of a dooring collision and the roadway conditions that may have contributed to it. We identify the entities responsible for the street, obtain public records and surveillance footage, inspect the location, review applicable immunity questions, and document your medical expenses, lost income, and other damages.

If the evidence supports claims against more than one party, we evaluate the potential responsibility of the person who opened the door, the vehicle owner, contractors, and public entities. We then communicate with insurers, pursue an appropriate resolution, and prepare the case for litigation when necessary.

We assist injured cyclists and their families throughout Elizabethtown, Radcliff, Shepherdsville, Bardstown, Brandenburg, Leitchfield, Hodgenville, Louisville, Hardin County, Nelson County, LaRue County, Hart County, Meade County, Grayson County, Breckinridge County, Bullitt County, and Jefferson County.
