If a traffic signal seems to be malfunctioning or a recurring timing problem concerns you, describe the condition precisely and report it through the appropriate channel. A dark signal, a flashing display, a light that appears not to serve one approach, and a long but otherwise ordinary wait are different observations.

You do not need to diagnose a controller or prove why a signal behaved that way to make a useful report. Explain where you were, which direction you faced, what you saw, and when it happened.

Separate an emergency from a service request

If there is an immediate emergency, call 911. A routine online maintenance request is not a substitute for emergency assistance. The NCDOT safety and emergencies page directs people to notify local law enforcement when an unexpected roadway condition creates an emergency.

Make any call or report from a safe location. Do not use a phone while driving, enter the intersection to inspect a signal, or attempt to direct traffic yourself. Follow instructions from responding authorities.

Use Charlotte’s service channels for a local concern

CharMeck 311 provides information and service-request routing for Charlotte and Mecklenburg County, including Charlotte Department of Transportation services. The city offers 311, online requests, and the CLT+ app. If you are unsure which department maintains the signal, give the location and ask for the appropriate routing.

CDOT describes its signal-systems responsibilities as including traffic signals, pedestrian signals, and coordinated signal systems within the city. That does not mean every concern on a road bearing a state route number should be sent to the same office; confirm the responsible agency for the specific location.

For a signal outside a city network, NCDOT’s safety page links to its traffic-signal reporting process. It asks people to describe what the signal appears to be doing wrong and provide a follow-up number. If an agency redirects your request, retain the reference and the name of the office receiving it.

Describe the approach, not just the intersection

A report that “the light is wrong at the shopping center” can leave several possible locations and movements. Include details you already know or can obtain safely:

  • Location: Both street names and a nearby address or entrance if the location could be confused with another intersection.
  • Approach: Your direction of travel and whether the issue concerned a through lane, left turn, right turn, or pedestrian crossing.
  • Display: What was visible: dark, flashing red, flashing yellow, a particular arrow, or another observed condition.
  • Time: Date, approximate time, and whether you observed one occurrence or a recurring pattern.
  • Context: Construction, an officer directing traffic, a power outage, or another condition you actually observed.

For example: “At about 5:20 p.m. Tuesday, I was in the northbound left-turn lane at the intersection of these two streets. I saw the through traffic move twice but did not see a left-turn arrow.” That is a useful observation. It is different from claiming that a detector failed or that two conflicting movements received green at the same moment.

Report a timing concern without assuming a defect

Separate an estimated wait from a measured interval, and state whether you watched the complete sequence. If you arrived during part of a cycle, say so. An expectation based on yesterday’s trip is not a measurement of today’s operation.

Describe the practical concern, such as a queue extending beyond a turn lane or difficulty completing a crossing, without prescribing an engineering solution. Agency staff can determine which records and review are appropriate. A report does not establish that a timing change is required or promise when a review or repair will occur.

If you already have a relevant image or recording obtained safely, retain its original version and explain its time, location, and viewing direction. Do not make repeated drives or stand in an unsafe position to create evidence. A camera showing one signal face may not show the indication facing another approach.

Keep a simple follow-up record

Save the request number, submission date, description, attachments, and response. If a later observation differs, identify its date and describe the change rather than replacing the first account. “Normal when checked later” and “no problem was ever present” are different statements.

If a crash occurred, reporting a maintenance concern and evaluating the crash are separate tasks. The guide to traffic-signal timing records after a collision explains how programmed timing, actual operation, video, and driver accounts differ. A service request alone does not establish fault or medical causation.

For questions about an injury claim arising from the collision, Rosensteel Fleishman’s car accident team can review the available facts and records. Report the immediate roadway concern to the responsible public agency.
