A broken traffic light can turn an everyday Texas intersection into a perilous, bewildering situation in seconds. When a signal goes totally dark, flashes unexpectedly, gives conflicting indications or changes in an unusual sequence, drivers may not know who has the right of way. If that confusion leads to a serious accident, deciding who is liable can be more complicated than just figuring out which car entered the intersection first. Depending on the circumstances, a negligent driver, another road user, a governmental entity responsible for the signal, a contractor, or several parties may share responsibility. This guide from Roxell Richards Injury Law Firm explains how Texas law may apply to accidents involving Traffic Light Malfunction signals, what evidence can help establish fault, and what injured people should consider before dealing with insurance companies or potential governmental claims.

What Is Considered a Traffic Light Malfunction?
A traffic light malfunction occurs when a traffic-control signal does not operate as intended. The problem may be immediately obvious, such as when every signal head at an intersection is completely dark. In other cases, the defect can be much harder for a driver to recognize.
Examples can include:
-
- A traffic signal that has lost electrical power
- A signal stuck permanently on red or green
- Conflicting green lights directing intersecting traffic into the intersection
- Incorrect or unusually short signal cycles
- Flashing lights that are not functioning as intended
- Individual signal heads that are dark while others continue operating
- Damaged signal equipment following a collision or storm
- Wiring, controller, sensor, or electrical problems
- Poorly positioned or damaged signal heads that interfere with visibility
An unusual signal operation does not necessarily prove the traffic light was defective. A proper investigation may require traffic-signal maintenance records, photographs, video, witness accounts, reports of prior problems, and technical information about the intersection.
This distinction matters because identifying the actual cause of the malfunction can influence who may ultimately be legally responsible.
Why Malfunctioning Traffic Lights Cause Serious Accidents?
Traffic signals establish predictable patterns. Drivers expect that when their light is green, traffic moving in conflicting directions will generally be stopped.
A malfunction destroys that predictability. Imagine a driver approaching a busy Texas intersection believing that the signal permits them permission to proceed. At the same moment, a driver traveling perpendicular to that vehicle may also believe the intersection is open.
Neither vehicle may have much time to react. The resulting collision is frequently a side-impact or “T-bone” crash. These collisions can cause severe injuries because the side of a passenger vehicle generally provides less distance between the point of impact and its occupants than the front or rear of the vehicle.
A malfunctioning signal can also contribute to:
-
- Head-on crashes
- Rear-end collisions
- Motorcycle accidents
- Pedestrian accidents
- Bicycle accidents
- Commercial truck crashes
- Multi-vehicle pileups
High-speed intersections are especially dangerous because a driver’s stopping distance increases with speed while the time available to identify and react to a signal problem decreases.
What Should Texas Drivers Do When a Traffic Signal Is Not Working?
Texas law specifically addresses an important situation involving a nonfunctioning traffic signal.
Under Texas Transportation Code § 545.151, an operator approaching an intersection must stop, yield, and grant immediate use of the intersection when a traffic-control signal is present but does not display an indication in any of the signal heads. A driver may enter the intersection after stopping and not in conflict with traffic on another street or roadway.
Drivers should not take for granted that they have right of way and drive thru a fully dark signal. They should slow down, stop if they have to, look at the traffic carefully and only go on when it is safe to do so.
It gets more complicated if a traffic light malfunction is not obvious. For example, suppose two directions simultaneously receive green signals. Each driver might reasonably believe the signal is functioning normally. Establishing liability would then require determining exactly what the signal displayed, how the drivers responded, and why the malfunction occurred.
Who Can Be Liable for a Traffic Light Malfunction?
One of the most important questions after this type of collision is, “Who actually caused the accident?
There may not be a single answer. The evidence may point to the following potentially responsible parties:
A Careless Driver
Even if a traffic signal is not working, a driver can be held liable.
For example, liability could potentially arise if a driver:
-
- Failed to stop at a dark signal
- Entered an intersection when it was unsafe
- Was speeding
- Was texting or otherwise distracted
- Was impaired by alcohol or drugs
- Failed to maintain a proper lookout
- Ignored obvious hazards
- Made an unsafe turn
- Drove aggressively through a malfunctioning intersection
The presence of a defective signal does not automatically excuse unsafe driving.
A Governmental Entity
A city, county, state agency, or other governmental unit may have responsibility for certain traffic-control devices.
However, claims against governmental entities are very different from ordinary negligence claims. Governmental immunity and the Texas Tort Claims Act can significantly affect whether a claim is legally permitted.
A Maintenance Service Provider
Some government agencies contract with private companies to inspect, install, maintain or repair traffic-control equipment.
The investigation could bring in a contractor if the traffic light malfunction was caused by negligent maintenance or repair.
Whether a private contractor can be held liable in fact depends on its duties, contract, conduct and the facts relating to the failure.
A Manufacturer or Equipment Provider
Less commonly, a defective traffic-signal component could contribute to an accident.
These cases can require technical analysis to determine whether the problem resulted from a defective product, improper installation, inadequate maintenance, physical damage, software or controller problems, or another cause.
A Third Party
A third party may also cause signal damage. For example, a vehicle might strike a traffic-control cabinet, or utility equipment could sustain damage. For example, a vehicle might strike a traffic-control cabinet, utility equipment could be damaged, or construction might impact electrical systems.
Identifying that party can significantly change the liability analysis.
Can a City or Government Agency Be Held Responsible?
Potentially but government liability is one of the most complicated aspects of a case involving a malfunctioning traffic light in Texas.
The Texas Tort Claims Act contains specific provisions addressing traffic and road signs, signals, and warning devices.
Under Texas Civil Practice and Remedies Code § 101.060, the Act generally does not apply to a claim based merely on a governmental unit’s discretionary failure to initially place a traffic or road sign, signal, or warning device.
The statute also addresses an existing device’s absence, condition, or malfunction. A governmental unit’s liability can depend, among other issues, on whether the responsible governmental unit had notice of the problem and failed to correct it within a reasonable time. The statute separately addresses situations where a third party removed or destroyed a device.
That makes notice a particularly important issue. Suppose a traffic light fails at 3:00 p.m. and a collision occurs seconds later. The legal analysis may be very different from a situation where residents had repeatedly reported the same malfunction for several days and the responsible entity allegedly failed to address it.
Possible evidence of notice may include:
-
- Past citizen complaints
- 311 service requests
- Reports to the police
- Maintenance records
- Work orders
- service log
- Traffic management center records
- Previous crash reports
- Emails or communications about the crossroads
- Reports by City Employes
- Contractor communications
Such records can help establish when the responsible entity knew of the problem and what was done about it.
Governmental immunity issues are very fact specific, and an accident involving a city- or state-controlled traffic signal should be carefully analyzed and not treated like a run-of-the-mill insurance claim.
How Driver Negligence Affects Liability?
Even if investigators determine that the signal was faulty, driver behavior matters. Motorists in Texas must use reasonable care under the circumstances.
Think of an intersection where all the lights are off.
A driver stops, looks at the traffic, and starts to cross the intersection slowly. Another comes up fast, drives straight thru without stopping.
While the signal failure was a factor in the dangerous condition, the second driver’s behavior may be an important one in determining liability.
Insurance companies and attorneys may investigate issues such as:
-
- Vehicle speed
- Braking
- Driver visibility
- Distraction
- Cellphone use
- Intoxication
- Right-of-way rules
- Weather
- Road conditions
- Whether the signal problem was obvious
- Where each vehicle entered the intersection
- Whether either driver could have avoided the collision
That is why evidence from the moments immediately before impact can become critical.
Can Multiple Parties Share Fault in Texas?
Yes. Texas uses a proportionate-responsibility system.
Under Chapter 33 of the Texas Civil Practice and Remedies Code, if the statute’s requirements are met, a factfinder may apportion percentages of responsibility among the parties involved and responsible third parties.
This matters greatly in an accident involving a malfunctioning traffic light because several contributing causes may exist.
For example, an investigation could potentially determine the following:
-
- One driver entered the intersection unsafely;
- Another driver was speeding;
- A traffic signal was malfunctioning, and
- A responsible entity had prior notice of the signal problem.
The percentages finally attributed depend on the evidence and the applicable law.
Texas’s modified comparative-fault rules can also affect an injured person’s recovery. A claimant’s own percentage of responsibility can reduce recoverable damages, and Texas law generally bars recovery when the claimant’s percentage of responsibility exceeds 50 percent.
For this reason, statements made immediately after a collision can matter. An insurer may try to use a driver’s description of the accident to shift a larger share of responsibility onto that driver.
Evidence That Can Prove a Traffic Light Was Malfunctioning
Evidence disappears quickly after intersection accidents.
A signal that was malfunctioning at 5:00 p.m. could be repaired before an injured driver or family member has an opportunity to document the problem.
That makes prompt investigation particularly valuable.
Photos and Videos
Photographs or video from immediately after the collision may establish the following:
-
- Which signal heads were illuminated
- Whether signals were completely dark
- Flashing patterns
- Physical damage
- Intersection layout
- Vehicle positions
- Skid marks
- Weather and visibility
- Construction activity
If it is safe to do so, recording the condition of the intersection can preserve information that may otherwise disappear.
Surveillance Footage
Nearby businesses, homes, apartment complexes, parking facilities, gas stations, buses, and other locations may have cameras.
Traffic-management systems may also have relevant footage or data. Video can potentially show not only the collision but also the signal’s operation immediately before it.
Because many recording systems automatically overwrite older footage, preservation requests may need to be sent quickly.
Dashcam Video
Dashcams can provide especially valuable evidence in disputed intersection cases.
Footage may show:
-
- The color or condition of the signal
- The driver’s speed and movement
- Other vehicles entering the intersection
- How long a light remained unchanged
- Whether the signal was dark
- The sequence immediately before impact
Witness Statements
Independent witnesses can be extremely helpful. Someone waiting at a nearby intersection, walking along the street, working at a business, or traveling behind one of the vehicles may have seen the malfunction.
Obtain witness names and contact information when possible.
Traffic Signal Maintenance Records
Maintenance and repair records can potentially reveal whether the signal had the following:
-
- Failed previously
- Received repeated complaints
- Recently undergone repairs
- Experienced electrical problems
- Been scheduled for maintenance
- Been damaged
- Generated fault notifications
These records can become particularly significant when notice to a governmental entity is disputed.
Electronic Vehicle Data
Some vehicles preserve crash-related information that may help accident reconstruction professionals evaluate speed, braking, acceleration, and other factors.
Cellphone Records
When distracted driving is suspected, cellphone evidence may become relevant to determining whether a driver was texting, calling, or otherwise using a device around the time of the collision.
Common Injuries in Intersection Accidents
Intersection crashes are often serious trauma, especially when one vehicle collides with the side of another at high speeds.
Possible injuries include:
Traumatic Brain Injury
A person’s head can hit the window, the pillar, the dashboard, the steering wheel, or some other interior surface.
Brain injuries can be as minor as concussions, or they can be severe traumatic injuries that may cause long-term cognitive and physical limitations.
Neck & Back Injuries
Sudden forces can injure muscles, ligaments, vertebrae and spinal disks.
Some symptoms may not show up for hours or days after the collision.
Spinal Cord Injury
Serious accidents may cause damage to the spinal cord resulting in partial or complete paralysis and requiring extensive rehabilitation.
Fractures In a violent crash at an intersection
arms, legs, ribs, hips, wrists, ankles and facial bones can all be broken.
Internal Injuries
The impact can cause internal bleeding or damage to internal organs, which may not be immediately obvious and can be fatal.
Psychological harm
Serious crashes can also affect a person emotionally, like anxiety, sleep problems, and fear of driving or intersections.
If you are experiencing significant symptoms after a collision, you need to get the appropriate medical attention and not just assume the injury will heal itself.
Compensation Available After a Traffic Light Accident
If an injury is caused by another party who is legally liable, the injured person may be able to recover damages for applicable losses.
Possible damages include:
Costs of Health Care Qualifying Medical Expenses
A claim may include past and future qualifying medical expenses, including:
-
- Emergency transportation
- Hospital treatment
- Operation
- Doctor’s visits Image diagnostics
- Medical
- Physiotherapy
- Rehab
- Follow up treatment
Lost revenues In a claim
injuries that prevent a person from working may include lost earnings.
Reduced Capacity to Earn
The injuries may be severe or permanent and prevent a person from doing the same work or from earning the same income in the future.
Suffering and Pain
In Texas personal injury claims, non-economic losses related to physical pain, and other effects of an injury may be included, depending on the circumstances.
Physical Injury and Scarring
Serious injuries may cause permanent impairment or visible scars.
Property damage
Vehicle repairs and replacement value may be included as losses of property.
Compensation for Wrongful Death
If an intersection collision is fatal, surviving family members who qualify may have rights under Texas wrongful-death law.
The damages in any given case depend on the facts, evidence, responsible parties, insurance coverage and the legal rules that apply.
What To Do Right After a Traffic Light Malfunction Accident?
The steps you take after a collision can affect both your personal safety and your ability to determine what happened.
1. Find a Safe Place
If possible and safe, don’t stay in the traffic lane that is hazardous.
2. Call 911 When Needed
If there are serious collisions, call for emergency help if there are any injuries or immediate hazards.
Texas law also imposes reporting and other duties following certain collisions.
3. Seek Medical Attention
Some injuries are immediately obvious. Others are not.
Prompt medical evaluation can protect your health and create documentation connecting injuries with the collision.
4. Photograph the Signal
If you can safely document the intersection, photograph or record the traffic signals.
Try to capture several signal heads and directions rather than only one light.
5. Photograph the Entire Scene
Document:
-
- Vehicles
- Damage
- Debris
- Road markings
- Traffic signs
- Skid marks
- Intersection layout
- Weather
- Construction
- Obstructions
How Insurance Companies May Handle These Claims?
An insurer may initially treat a malfunctioning-signal collision as a dispute between two drivers.
For example, each driver might insist on the following:
“My light was green.”
Without independent evidence, the insurer may dispute which account is correct.
The insurance company may investigate:
-
- Police reports
- Driver statements
- Witness statements
- Vehicle damage
- Intersection photographs
- Surveillance video
- Traffic citations
- Electronic data
- Signal maintenance information
An insurer may also argue that even if the traffic signal malfunctioned, the injured driver should have recognized the danger and avoided the collision.
This is one reason independent evidence can be so important.
A photograph showing a completely dark signal, a video showing simultaneous greens, or records showing repeated reports of a malfunction can change the nature of the liability investigation.
Why Government Claims Require Special Attention?
A claim involving a governmental entity is not simply an ordinary car accident claim with the city added as another defendant.
Special statutes may apply. One particularly important issue is notice.
Under Texas Civil Practice and Remedies Code § 101.101, a governmental unit is generally entitled to notice of a claim under the Texas Tort Claims Act no later than six months after the incident. The notice must reasonably describe the claimed damage or injury, the time and place of the incident, and the incident itself. The statute also recognizes city charter and ordinance notice provisions, and it contains an exception where the governmental unit has the legally required actual notice.
This is important because a local government’s applicable notice requirement may require action well before the ordinary personal-injury lawsuit deadline.
Additionally, Texas generally provides a two-year limitations period for personal injury actions under Civil Practice and Remedies Code § 16.003, subject to exceptions and other applicable rules.
Waiting close to two years to investigate a potential government-related traffic-signal claim can therefore create serious problems.
Evidence can also disappear much sooner.
Surveillance recordings may be overwritten. Signals may be repaired. Vehicles may be destroyed or sold. Witnesses may become difficult to locate.
Early investigation can make a substantial difference.
How a Texas Car Accident Lawyer Can Help?
A traffic light malfunction case may require substantially more investigation than an ordinary rear-end collision.
An attorney handling the matter may need to determine who controlled the signal, whether the governmental unit had notice, whether contractors were involved, and whether other drivers contributed to the crash.
Possible actions could be:
Exploring the Crossroads
An attorney can take one look at the physical layout and determine which government agency or other entity is in charge of the signal.
Maintaining Evidence
Requests for preservation can be made to companies, government entities, contractors and others who may have video or electronic records.
Requesting Government Documents
The pertinent records could be:
-
- Maintenance records
- History of Repair
- Work Orders
- Objections
- Examination record
- Information on signal timing
- Recent incident reports
- Communications about the intersection
Contractors Under the Lens
If a private company has recently installed, repaired or maintained the traffic signal, its work and contractual obligations may need to be reviewed.
Working with Professionals
Depending on the case, attorneys may also work with professionals in accident reconstruction, engineering, medicine, vocational rehabilitation, economics and other fields.
Insurance Companies
A lawyer can talk to insurance companies, gather evidence, assess the losses claimed, and fight off efforts to unfairly pin the blame.
Assessment of Governmental Immunity Questions
If a governmental entity is involved, counsel can determine whether the claim is permissible under the Texas Tort Claims Act or some other legal theory, and what procedural requirements apply.

Frequently Asked Questions
1. Who Is at Fault if a Traffic Light Is Completely Out?
Fault depends on the circumstances. If a driver ignores a completely dark signal and enters the intersection without stopping, that conduct may be important evidence of negligence.
The investigation also may include the reason for the failure of the signal and whether another responsible party contributed to the dangerous condition.
2. Can I Sue a Texas City for a Broken Traffic Light?
Maybe. But not every malfunctioning traffic light makes a good claim against a city. Texas governmental entities have substantial immunity protections.
Because these claims are legally complex and may involve special notice requirements, anyone seriously injured in this type of accident should consider obtaining a case-specific legal evaluation promptly.
3. What if Both Drivers Say They Had a Green Light?
This is one of the most difficult factual disputes in intersection crashes. Instead of relying on the drivers’ memories, investigators may find objective evidence.
Such evidence can include: Traffic cameras Commercial monitoring cameras Camera – Dash Cams Eyewitness evidence Data from a signal controller Service records Observations by the police Vehicle Details “Physical evidence” of the accident If there really were conflicting green lights, figuring out why that happened can become an issue in the case.
A quick effort to safeguard evidence could be especially critical as camera footage can be overwritten.
4. How Much Time Do I Have to File a Traffic Light Accident Claim in Texas?
For many Texas personal injury cases, Civil Practice and Remedies Code § 16.003 provides a two-year limitations period. But that does not mean every injured person can safely wait two years.
If a governmental unit may be responsible, the Texas Tort Claims Act generally requires notice no later than six months after the incident, while applicable city charter or ordinance provisions may also impose notice requirements.
5. What is the most important evidence in a traffic light failure case?
There is no single piece of evidence that matters in every case, but some of the most valuable evidence can include:
- Video of the signal malfunction
- Dashcam footage
- Independent witness testimony
- Traffic-signal maintenance records
- Previous malfunction complaints
- Government work orders
- Police reports
- Photographs of the intersection
- Electronic vehicle data
- Medical documentation
- Evidence of lost income and other damages
When government liability is being considered, records showing when the responsible governmental entity received notice of the malfunction may be especially important because Texas law specifically addresses notice in connection with malfunctioning traffic-control devices.
