Washington Dashcam Laws: Mounting Rules, Audio Recording, and Evidence (2026)

Dashcams are legal in Washington. Silent video of public roads requires no consent, but any dashcam that records in-car audio triggers all-party consent under RCW 9.73.030. Washington also restricts windshield mounting under RCW 46.37.410, so most drivers mount cameras on the dashboard instead.

Dashcams have become increasingly popular among Washington drivers for documenting accidents, road rage incidents, and everyday driving. Washington law permits dashboard cameras, but two important legal considerations apply: windshield obstruction rules that limit where cameras can be mounted, and audio recording consent requirements that restrict what the camera can capture inside the vehicle. Understanding both sets of rules ensures your dashcam operates within the law and produces footage that is admissible in court.

Are Dashcams Legal in Washington?

Yes. Washington does not prohibit the use of dashboard cameras. You may install and operate a dashcam in your personal or commercial vehicle. However, two separate bodies of law regulate different aspects of dashcam use:

1. Windshield obstruction laws (RCW 46.37.410) control where you can mount the camera
2. Audio recording laws (RCW 9.73.030) control whether the camera can record conversations inside the vehicle

Windshield Mounting Rules

RCW 46.37.410: Windshield Obstruction

Washington's vehicle equipment statute, RCW 46.37.410, restricts what can be placed on a vehicle's windshield. The statute provides that no person shall drive any motor vehicle with any sign, poster, or other nontransparent material upon the front windshield, side wings, or side or rear windows of the vehicle that obstructs the driver's clear view of the highway or any intersecting highway.

Practical Mounting Guidelines

While Washington law does not specifically mention dashcams, the obstruction statute means that any camera mounted on the windshield must not obstruct the driver's view. Best practices include:

• Mount behind the rearview mirror: Position the camera directly behind the rearview mirror, where it is least likely to obstruct the driver's view.
• Use a small camera: Choose a compact dashcam that occupies minimal windshield space.
• Dashboard mounting: Mounting the camera on the dashboard rather than the windshield avoids the obstruction issue entirely. Dashboard-mounted cameras comply with the statute regardless of size.
• Avoid the center of the windshield: Never mount a dashcam in the center of the driver's sightline.

Enforcement and Penalties

Driving with an obstructed windshield is a traffic infraction under Washington law. While enforcement is typically at the officer's discretion, having a poorly placed dashcam provides a basis for a traffic stop and citation. The fine for a windshield obstruction violation is typically modest, but it can lead to additional scrutiny of the vehicle.

Audio Recording Rules for Dashcams

The Two-Party Consent Problem

This is where dashcam law gets complicated in Washington. Many dashcams come with built-in microphones that record audio inside the vehicle. Under RCW 9.73.030, recording any private conversation without the consent of all parties is illegal.

When your dashcam records audio of conversations with passengers, you are potentially capturing private communications subject to the all-party consent requirement. This means:

• Driving alone: No consent issue. You are the only party to any conversation.
• Driving with passengers who know about the dashcam: If you inform passengers that the dashcam records audio and they remain in the vehicle, this likely constitutes implied consent.
• Driving with passengers who do not know about the dashcam: Recording their private conversations without disclosure violates RCW 9.73.030.

Solutions for Audio Compliance

There are several ways to comply with the audio recording requirement:

Option 1: Disable audio recording. Most dashcams allow you to turn off the microphone in the settings menu. This eliminates the consent requirement entirely. Silent video of the road ahead does not require consent.

Option 2: Post a visible notice. Place a clearly visible sticker or sign in your vehicle stating: "Audio and video recording in progress." Passengers who see the notice and remain in the vehicle have arguably given implied consent by continuing the conversation. RCW 9.73.030(3), however, describes an announcement that is itself recorded, and no Washington appellate decision we located has held that a sign alone is enough.

Option 3: Verbal announcement. Inform passengers verbally each time they enter the vehicle that the dashcam records audio. This is the most reliable method but the least practical for rideshare drivers or others who regularly carry different passengers.

Rideshare and Taxi Drivers

Rideshare drivers (Uber, Lyft) and taxi drivers in Washington face particular challenges with dashcam audio:

• Frequent new passengers: Each new passenger is a new party who must be informed about audio recording.
• Visible signage: A prominent sign visible to all passengers, such as "For safety purposes, this vehicle is equipped with audio and video recording," helps show passengers knew about the recording. No Washington appellate decision we located has held that a sign alone satisfies RCW 9.73.030, so pair it with a short spoken notice that the dashcam captures, or turn audio off.
• App-based disclosure: Rideshare platforms may include recording disclosures in their terms of service, but neither that nor a sign is a recorded announcement under RCW 9.73.030(3); a spoken notice captured on the recording, or turning audio off, is the reliable approach.
• Washington Utilities and Transportation Commission rules: For regulated taxi services, additional rules may apply.

Dashcam Footage as Evidence

When Dashcam Footage Is Admissible

Dashcam footage is generally admissible as evidence in Washington courts if:

• The footage was obtained legally (no consent violations for audio)
• The footage is relevant to the case
• The footage has not been altered or tampered with
• The footage is authenticated (you can verify it came from your camera and the date/time are accurate)

When Dashcam Footage May Be Excluded

Footage may be excluded from court proceedings if:

• Audio was recorded without consent: Under RCW 9.73.050, any information obtained in violation of the Privacy Act is inadmissible. If your dashcam recorded private conversations without consent, the entire recording (including the video portion) may be challenged.
• Chain of custody issues: If the footage has been edited, the original data has been corrupted, or there are gaps in the recording timeline.
• Irrelevant or prejudicial content: Courts may exclude footage that is more prejudicial than probative.

Using Dashcam Footage After an Accident

After a traffic accident, dashcam footage can be valuable evidence for:

• Insurance claims: Dashcam footage showing the other driver's fault can support your claim. Most insurance companies accept dashcam footage.
• Personal injury lawsuits: Footage demonstrating how the accident occurred can be powerful evidence.
• Traffic citations: Footage showing that you were following traffic laws can help contest a citation.
• Hit-and-run identification: Footage may capture the other vehicle's license plate.

Providing Footage to Law Enforcement

If your dashcam captures evidence of a crime (hit and run, road rage, DUI), you can voluntarily provide the footage to law enforcement. Key considerations:

• You are not required to provide footage, but cooperation can be helpful
• Make a copy of the footage before providing it to police
• The footage becomes part of the police case file
• If subpoenaed, you must produce the footage

Commercial Vehicle Dashcams

Employer-Installed Dashcams

Washington employers who install dashcams in commercial vehicles must navigate both the Privacy Act and employment law:

• Audio recording: If the dashcam records audio of conversations between the driver and passengers or coworkers, the employer must notify all parties. Under RCW 9.73.030, the all-party consent requirement applies.
• Employee notification: Employers should inform drivers in writing that their vehicles are equipped with dashcams and whether the cameras record audio.
• Employee handbook: Include dashcam policies in the employee handbook and have drivers acknowledge the policy in writing.
• Privacy considerations: Cameras should not be aimed inside the cab in a way that captures private activities during breaks or rest periods.

Fleet Management Cameras

Many fleet management systems include forward-facing and driver-facing cameras. For Washington-based fleet operations:

• Forward-facing cameras recording the road are generally unproblematic
• Driver-facing cameras raise privacy concerns, especially during mandated rest breaks
• Audio recording in the cab requires disclosure and consent
• GPS tracking combined with camera data should be disclosed in employment agreements

Dashcam Best Practices for Washington

Setup

• Mount the camera on the dashboard or behind the rearview mirror to avoid windshield obstruction
• Disable audio recording unless you have a system in place to obtain consent
• Set the camera to loop recording so it continuously overwrites old footage and always captures the most recent events
• Enable date and time stamps on the footage for authentication purposes
• Use a dashcam with GPS capabilities that records speed and location data

After an Incident

• Do not remove or turn off the dashcam after an accident. The footage from the moments after a collision can be just as important as the collision itself.
• Save the footage immediately. Most dashcams can lock a file to prevent overwriting. Press the save button or remove the memory card after an incident.
• Make a backup copy before providing footage to anyone.
• Note the file name, date, and time of the relevant footage.

Maintenance

• Regularly check that the camera is functioning properly
• Clean the lens to ensure clear footage
• Update firmware when updates are available
• Replace memory cards periodically, as SD cards can degrade with constant use
• Check mounting stability, especially in extreme temperatures

Frequently Asked Questions

Are dashcams legal in Washington state?

Yes, dashcams are legal in Washington. However, you must mount the camera in a way that does not obstruct your view of the road, as required by RCW 46.37.410. If your dashcam records audio of conversations inside the vehicle, you must comply with Washington's all-party consent law (RCW 9.73.030) by disabling audio or informing all passengers.

Can I mount a dashcam on my windshield in Washington?

Washington's windshield obstruction law (RCW 46.37.410) prohibits nontransparent materials that obstruct the driver's view. You can mount a small dashcam behind the rearview mirror where it does not block your sightline. For guaranteed compliance, mount the camera on the dashboard instead of the windshield.

Do I need to tell passengers about my dashcam in Washington?

If your dashcam records audio, yes. Washington's all-party consent law requires that all parties to a private conversation consent to recording. You can comply by turning off the dashcam's microphone, or by telling each passenger, out loud and on the recording, that the camera records audio. A visible sign helps show passengers knew about the recording and may support implied consent, but no Washington appellate decision we located has held that a sign alone satisfies RCW 9.73.030, so a spoken announcement is the reliable method. Silent video does not require passenger notification.

Can dashcam footage be used as evidence in Washington?

Yes, dashcam footage is generally admissible in Washington courts if it was obtained legally and has not been altered. However, if the footage includes audio recorded without consent, it may be challenged under RCW 9.73.050, which makes illegally obtained recordings inadmissible. Footage should include accurate date and time stamps for authentication.

Can my employer require a dashcam in my work vehicle in Washington?

Yes, employers can install dashcams in company vehicles. However, if the camera records audio, the employer must notify drivers and comply with the all-party consent requirement under RCW 9.73.030. Employers should include dashcam policies in employee handbooks and have drivers acknowledge the policy in writing.
