The light was green in your direction. It was also green in the cross direction. The impossible happened: both lights were green, and you collided with another vehicle that legitimately had a green light.
Signal malfunctions cause accidents that no driver could have avoided. Can you sue the government responsible for signal maintenance?
How Signal Malfunctions Cause Accidents
Traffic signals fail in several ways that cause collisions.
Conflicting signals display green in incompatible directions simultaneously. This software or hardware failure gives multiple drivers legitimate right of way, making collision inevitable when they enter the intersection together.
Signal blackouts leave intersections without functioning signals during power outages or equipment failure. Confusion about right of way leads to accidents.
Stuck signals remain on one phase without cycling. Cross traffic faces eternal red while one direction perpetually has green. Drivers waiting forever eventually proceed against the apparently stuck light.
Mistimed signals create yellow phases too short for safe stopping or red phases too short for intersection clearance.
Sensor failures prevent signals from detecting waiting vehicles, leaving them perpetually ignored while other directions cycle normally.
Evidence Preservation Is Critical
Signal malfunction evidence disappears quickly. Governments repair malfunctioning signals promptly. The malfunction that caused your accident may be fixed before anyone documents it.
Call 911 immediately and report the signal malfunction. The dispatch recording preserves evidence of your complaint.
Obtain witness statements from other drivers and bystanders who observed signal behavior. Their accounts corroborate your description.
Request police investigation of signal operation. Officers may document observed malfunction or call traffic engineers to evaluate signal function.
Photograph the intersection and signals from multiple angles. While photographs don’t capture malfunction, they document conditions.
Send immediate preservation letters to the responsible government entity demanding they preserve signal controller logs, maintenance records, and event data before routine overwriting occurs.
Signal Controller Event Logs
Modern traffic signals maintain electronic logs recording signal phases, timing, and detected malfunctions. These logs provide objective evidence of what the signal displayed and when.
Obtaining logs requires prompt action. Many systems overwrite logs after days or weeks. Preservation demands must reach the responsible entity before data is lost.
Open records requests under Georgia’s Open Records Act can obtain signal logs, maintenance records, and related documentation once you know what to request.
Traffic engineering experts can interpret signal logs to determine whether malfunction occurred and what the signal displayed at accident time.
Government Liability for Signal Maintenance
Governments have duties to maintain properly functioning traffic signals. Signal maintenance is generally ministerial, not discretionary, making claims more viable than design immunity cases.
O.C.G.A. Section 32-4-93 establishes municipal liability for failures to maintain streets in safe condition. This includes traffic control devices.
The duty includes regular inspection for proper operation, prompt response to malfunction reports, adequate maintenance to prevent failures, and reasonable updating of aging equipment.
Proving Knowledge or Constructive Notice
Like other road defect claims, signal malfunction claims typically require showing the government knew or should have known of the problem.
Prior malfunction reports establish actual knowledge. Obtain records of prior complaints about the specific signal.
Maintenance history showing recurring problems establishes knowledge of equipment issues. A signal repaired repeatedly for the same problem suggests known unreliability.
Equipment age and condition may establish constructive notice. Ancient equipment operating beyond normal lifespan is predictably prone to failure.
Manufacturer and Contractor Liability
Traffic signal equipment manufacturers may be liable for defective products that malfunction.
If signal hardware failed due to design or manufacturing defects, product liability claims target the manufacturer.
If installation or maintenance contractors performed negligent work, claims may proceed against those contractors.
Identifying all responsible parties, including government, manufacturers, and contractors, maximizes recovery potential.
Defense Arguments
Governments defend signal malfunction claims with several common arguments.
Sudden failure without prior warning establishes no notice. If equipment failed unexpectedly without prior symptoms, the government had no opportunity to repair before the accident.
Regular inspection and maintenance establishes reasonable care. Records of proper maintenance programs support defense positions.
Driver fault arguments suggest that even with malfunction, drivers should have noticed danger and stopped. This argument has less force when signals gave conflicting green indications than when signals were completely dark.
Practical Considerations
Signal malfunction claims require substantial evidence that may not exist if not quickly preserved.
Consider whether adding signal malfunction claims to a case already involving driver liability is worth the additional complexity.
Government defendants have substantial resources and strong incentive to defend infrastructure claims.
Expert costs for traffic engineering testimony add to litigation expense.
Evaluate realistic liability theories and available evidence before committing resources to signal malfunction claims.
Signal malfunction claims require prompt evidence preservation and expert analysis. This article provides general information about signal malfunction claims in Georgia. For specific guidance, consult immediately with a Georgia personal injury attorney to preserve evidence.
