HB 624 — Red Light Camera Delay Interval (summary)

Status: Passed First Reading (per provided info)
Introduced: November 12, 2024
Statutory change proposed: Adds new subsection (f) to G.S. 20‑158

Purpose

Clarify when a red‑light camera (traffic control photographic system) may record a violation and require that signal timing (yellow and red clearance intervals) at intersections with cameras be established according to engineered, documented timing and the Manual on Uniform Traffic Control Devices (MUTCD). The bill is intended to ensure fair, consistent enforcement by linking camera citations to properly designed signal timing.

Key provisions

  • Adds a new subsection (f) to G.S. 20‑158 specifying requirements for traffic control photographic systems used to enforce red light violations:
    • Definition of violation: A violation is recorded when a vehicle enters and proceeds into the intersection after the onset of a steady circular red or steady red arrow and the applicable red clearance interval has expired.
    • Timing standards: The yellow change interval and the red clearance interval at intersections monitored by cameras must be no shorter than the durations specified on the traffic signal "plan of record" — a traffic signal plan signed and sealed by a licensed professional engineer (PE).
    • Compliance with MUTCD: Signal timing must also comply with the provisions of the most recently adopted Manual on Uniform Traffic Control Devices.
  • Scope: Applies to any enforcement of G.S. 20‑158 by a traffic control photographic system, including enforcement conducted by municipalities authorized under relevant statutes.
  • Effective date: Becomes effective 60 days after the act becomes law.

Who is affected

  • Motorists: May see changes in how and when red‑light violations are recorded; could reduce citations where clearance intervals were previously too short.
  • Municipalities and local traffic agencies: Must ensure signal timing plans are documented, PE‑signed/sealed, and compliant with MUTCD for intersections with cameras.
  • Camera vendors and enforcement contractors: May need to verify timing documentation before supporting enforcement.
  • Courts and administrative enforcement processes: Could see changes in evidence and defenses tied to documented timing and clearance intervals.

Practical implications / likely impacts

  • Enforcement reliability: Tying violations to an engineered plan and MUTCD standards can reduce disputes over improperly timed signals and strengthen the legal basis for camera citations.
  • Administrative and engineering workload: Municipalities may need to audit signal timing, obtain or update signed/sealed plans, and possibly lengthen yellow/red clearance intervals to meet standards — incurring engineering and implementation costs.
  • Potential reduction in contested citations where prior timings were inadequate; conversely, areas with noncompliant timing may see enforcement paused until corrected.

If enacted, the measure emphasizes engineering-backed, standardized signal timing as the baseline for automated red‑light enforcement.
