Do Traffic Cameras Record?
The answer varies significantly by camera type and operating agency. Some continuously record, some trigger on events, and many stream live without storing footage at all.
VIEW CAMERAS →Whether a traffic camera records depends on its purpose, location, and the agency operating it. Department of Transportation (DOT) cameras that monitor traffic flow typically stream live without storage, while enforcement cameras (red light, speed) always record violations. In 2023, over 1,086 people were killed in crashes involving red light running, highlighting why these recording systems are critical for public safety.
According to the FHWA, real-time traffic monitoring helps drivers make safer, more informed decisions. Insurance Institute for Highway Safety (IIHS) research indicates that the presence of red light cameras can reduce fatal red light running crashes by 21% in large U.S. cities.
Recording by Camera Type
- DOT Traffic Cameras: Most stream live only, no recording (or 24-72 hour retention)
- Red Light Cameras: Always record violations, 30-90 day retention
- Speed Cameras: Record violations only, 30-90 day retention
- Toll Cameras: Continuous recording, typically 30 days
- Highway Monitoring: Some record continuously, 7-14 day retention
Most traffic monitoring cameras you see on highways and major intersections are DOT cameras designed solely for real-time traffic management. These typically don't record or only keep footage briefly for operational purposes.
Enforcement cameras (red light and speed cameras), however, always record because their purpose is to capture violations for citations. These systems are triggered by sensors detecting illegal activity.
How Traffic Camera Recording Works
Traffic camera recording systems operate in three primary modes, depending on their purpose and the technology deployed.
Live Streaming vs Storage
Many DOT traffic cameras stream live feeds to traffic management centers without storing any footage. These systems prioritize bandwidth efficiency and real-time monitoring over archival. The video signal is transmitted, displayed, and then discarded.
This is the most common setup for highway traffic monitoring cameras. Operators watch live feeds to detect incidents, manage traffic signals, and coordinate emergency response, but the footage disappears immediately after viewing.
Continuous Recording
Highway authorities, toll agencies, and some major metropolitan areas use continuous recording systems. These cameras capture and store everything 24/7 to a networked video recorder (NVR) or cloud storage system.
Continuous recording provides comprehensive coverage but requires significant storage infrastructure. Most agencies using this approach implement automatic deletion after a set retention period (typically 7-30 days) to manage storage costs.
Event-Triggered Recording
Enforcement cameras use sensors to detect violations and trigger recording only when needed. A red light camera, for example, records when its induction loop sensor detects a vehicle entering the intersection after the light turns red.
This approach dramatically reduces storage requirements while ensuring all relevant incidents are captured. The camera may run continuously but only saves footage when the trigger conditions are met.
How Long is Footage Stored?
Retention periods vary widely by agency and camera type. Understanding these timelines is critical if you need to request footage.
Typical Retention Periods
- DOT Traffic Cameras: 24-72 hours (if recorded at all)
- Highway Monitoring: 7-14 days for routine footage
- Enforcement Cameras: 30-90 days for violations
- Flagged Incidents: 60-90 days or longer if under investigation
- Legal Evidence: Indefinitely until case resolution
The retention period often depends on whether the footage is flagged. Unflagged routine monitoring footage may be automatically deleted after just days, while footage involved in an accident investigation or legal case can be preserved for months or years.
Different Retention Policies
Each type of traffic camera operates under different rules and retention standards. Here's what to expect from major camera categories.
DOT Traffic Cameras
Department of Transportation cameras prioritizing traffic flow monitoring typically have the shortest retention periods or no recording at all. These cameras feed live video to traffic management centers where operators monitor conditions and coordinate responses.
Recording: Most DOT cameras do not record. If they do, footage is typically kept for 24-72 hours.
Access: Footage is generally not available to the public unless subpoenaed for legal proceedings.
Purpose: Real-time traffic management, not surveillance or enforcement.
Act Quickly After Accidents
If you need footage from a DOT traffic camera after an accident, you must act immediately. Most agencies delete footage after 24-72 hours. Contact the relevant DOT within 24 hours and file a formal request or have your attorney subpoena the footage.
Enforcement Cameras
Red light cameras, speed cameras, and automated enforcement systems always record violations and maintain longer retention periods.
Recording: Event-triggered recording captures violations with timestamps and vehicle identification.
Retention: 30-90 days is standard, though policies vary by jurisdiction.
Access: Footage is used for citations and is accessible through legal requests or as part of contesting a ticket.
Toll & Highway Authority Cameras
Toll plazas and major highway systems often implement continuous recording for both tolling purposes and security.
Recording: Continuous 24/7 recording at toll plazas, exits, and major interchanges.
Retention: Typically 30 days for routine footage, longer if flagged for investigation.
Access: Available through public records requests or legal subpoena, though non-toll-related footage may require a warrant.
Municipal Traffic Cameras
Cities operate diverse camera systems with widely varying policies. Some municipalities record extensively for public safety, while others stream live only.
Recording: Policies vary dramatically by city. Check with your local traffic department.
Retention: Can range from no recording to 90+ days depending on local ordinances.
Access: Subject to local public records laws and privacy regulations.

Access Live Feeds →Can You Request Traffic Camera Footage?
Yes, but the process requires understanding which agency operates the camera and acting quickly before footage is deleted.
How to Request Traffic Camera Footage
Act Quickly: Most footage is deleted within 24-72 hours. Contact the agency immediately after an incident.
Identify the Agency: Determine which organization operates the camera (state DOT, city traffic department, toll authority, etc.). Location and camera type provide clues.
File a Public Records Request: Submit a formal Freedom of Information Act (FOIA) or state public records request in writing. Include the specific date, time, location, and camera ID if known.
Provide Detailed Information: The more specific your request, the better. Include intersection names, mile markers, direction of travel, and exact timestamps.
Expect Processing Time: Agencies typically have 10-30 days to respond to public records requests. Urgent requests may require legal action through an attorney.
Important considerations:
- Some agencies charge fees for footage retrieval and copying
- Privacy laws may redact portions of the footage
- Footage involved in ongoing investigations may be withheld
- Your attorney may be able to expedite requests through subpoena
If the footage has already been deleted, recovery is usually impossible. This is why immediate action is critical after any incident where camera footage might be relevant.
