A city, county, the State of Nebraska, a maintenance contractor, or one or more drivers may bear responsibility when a defective traffic signal contributes to a crash. Liability isn’t automatic just because a light was dark, stuck, mistimed, obstructed, or displaying conflicting signals. The outcome may depend on who controlled the signal, whether that party knew or reasonably should have known about the problem, what was done in response, and how each road user approached the intersection.
These cases can be more complicated than an ordinary two-vehicle collision — they may involve technical records and special claim procedures in addition to evidence about the drivers’ actions.
Key takeaways
A signal problem may involve more than a complete power outage. Examples include:
Not every irregularity proves negligence. Investigators may need to determine whether the signal actually malfunctioned, when the problem began, who was responsible, and whether it contributed to the collision.
Nebraska law states that when a signal at an intersection isn’t operating because of a power failure or another cause — and no officer, flagperson, or other traffic-control device is directing traffic — the intersection must be treated as a multi-way stop. The rule doesn’t apply when signal heads have been turned away from traffic or covered because the signal is officially out of service.
So each driver should stop and proceed cautiously under multi-way-stop rules. A driver who enters without stopping, travels too fast for conditions, fails to yield, or is distracted may still share or bear responsibility even though the signal failed. When the light is operating, Nebraska law generally requires drivers to obey the applicable signal — and green doesn’t grant an unlimited right to proceed. A turning driver, for example, must yield to traffic and pedestrians lawfully within the intersection or crosswalk. These details matter when the parties disagree about what each person saw and who entered first.
A city, county, or other local public entity. A local government may own or maintain the signal. A claim may examine whether it received prior complaints, had inspection or maintenance procedures, responded reasonably after learning of a dangerous condition, and had legally sufficient time to address it. A defect alone doesn’t establish negligence; governmental defenses and exceptions may apply, and the entity’s precise duties should be evaluated under the facts and current Nebraska law.
The State of Nebraska. The State may be involved when the signal is part of a state-controlled highway or intersection. Claims against the State follow the Nebraska State Tort Claims Act rather than the process for private parties. Confirm signal ownership and maintenance responsibility rather than assuming it from the road’s location or appearance.
A private maintenance or construction contractor. A government agency may hire a contractor to install, inspect, repair, program, or temporarily control a signal. Depending on the contract and the work, a contractor could become relevant if faulty installation, careless repair, improper programming, or inadequate temporary traffic control contributed to the crash.
One or more drivers. Drivers retain a duty of reasonable care. Even with a defective signal, the evidence may show a driver was speeding, failed to stop at a dark signal, followed too closely, drove distracted, or failed to yield. More than one driver — and potentially a public entity or contractor — may share the allocation of fault.
A key question is often whether the party responsible for the signal knew or reasonably should have known about the problem before the crash. Relevant evidence may include:
A defect that appeared moments before a crash may present different liability questions from a recurring problem documented over several days. What counts as reasonable notice and response may depend on the malfunction, the responsible party, and the circumstances.
These cases get harder once the light is repaired and the intersection returns to normal. Useful evidence may include photos or video of every signal face, nearby signs, skid marks, debris, vehicle damage, weather, and sight obstructions. Dashcam recordings, nearby business surveillance, traffic-camera footage, and witness accounts may help establish the signal display and each vehicle’s movement. The police report can help but may not capture every technical detail, and preservation requests may be appropriate for recordings and electronic or maintenance records that could be overwritten under routine retention practices.
People involved in a collision may also consider preserving:
Nebraska uses a modified comparative-negligence rule: a claimant’s damages are reduced by the negligence assigned to them, and recovery is barred if the claimant’s negligence is equal to or greater than the combined negligence of the parties they’re recovering from. (Neb. Rev. Stat. § 25-21,185.09.) Evidence that a signal malfunctioned wouldn’t necessarily resolve the entire claim — a fact finder may still evaluate whether a driver stopped, kept a proper lookout, adjusted speed, or could have avoided the collision. Fault allocations are fact-specific and shouldn’t be predicted from a brief description of the crash.
Deadlines are especially important when a signal is owned or maintained by a public entity.
For a claim under Nebraska’s Political Subdivisions Tort Claims Act, a written claim generally must be presented to the governing body within one year after the claim accrues, and a lawsuit generally must begin within two years after accrual, subject to limited statutory provisions and extensions. (Neb. Rev. Stat. § 13-919.)
For a claim under the Nebraska State Tort Claims Act, a written tort claim generally must be submitted to the State Risk Manager within two years after the claim accrues; the timing and procedure for filing suit depend on the Act and the disposition or withdrawal of the administrative claim. (Neb. Rev. Stat. § 81-8,227.)
An ordinary negligence action against a private party may be subject to a different limitations period, so determining the correct defendant and claim process can affect the deadline. Don’t assume the longest potentially available period applies, and claims involving minors, delayed discovery, wrongful death, or other circumstances may raise additional rules requiring individual review.
After addressing immediate medical and safety needs, consider:
Medical evaluation may be appropriate even when symptoms initially seem minor. A healthcare professional — not an insurer or attorney — should evaluate medical concerns and recommend treatment.
A Nebraska car accident attorney may help investigate signal ownership, identify potentially responsible parties, request preservation of electronic and maintenance records, and evaluate which claim procedure applies. Legal guidance may be particularly useful when the signal was repaired immediately, multiple parties dispute the light sequence, a government entity may be involved, or injuries are serious. An attorney can also explain how Nebraska’s comparative-negligence rule and government-claim requirements may apply to the particular facts. Consulting an attorney doesn’t mean a valid claim exists or that any specific outcome will occur.
Is the city automatically liable when a traffic light isn’t working? No. A claimant generally needs evidence connecting a responsible party’s act or omission to the dangerous condition and the crash. Ownership, notice, response time, governmental defenses, driver conduct, and causation may all matter.
What if both drivers say they had a green light? Investigators may review witness accounts, dashcams, business surveillance, controller or timing records, vehicle damage, and each vehicle’s location and movement. When the evidence conflicts, responsibility may become a question for the fact finder.
What if the signal was completely dark? Nebraska law generally requires an inoperative intersection signal to be treated as a multi-way stop when no officer, flagperson, or other device is directing traffic. Each driver’s conduct at the intersection will still be examined.
Can a driver and a government agency both share responsibility? Potentially. Nebraska’s comparative-negligence framework permits fault to be evaluated among responsible parties, but special rules apply to governmental defendants. The available claims and allocation depend on the evidence and applicable law.
A car accident claim may become more complicated when a defective or malfunctioning traffic signal contributes to the collision. Questions may arise about who owned or maintained the signal, whether the responsible agency had notice of the problem, how each driver approached the intersection, and whether a city, county, state agency, contractor, or another driver may share responsibility.
Evaluating the claim may require reviewing police reports, photographs, video recordings, witness statements, traffic-signal data, maintenance and inspection records, prior complaints, repair orders, medical records, insurance policies, wage-loss documentation, and vehicle-damage estimates. Organizing this evidence may help clarify how the malfunction occurred, whether it contributed to the collision, and which parties or insurance policies may need further consideration.
