Maryland Dash Cam Laws: The Complete Breakdown

1. Windshield Obstruction Laws

Maryland has strict laws about what can be mounted on your windshield, and dash cams fall under these regulations.

Maryland Transportation Code § 22-403.1:

Objects can only be mounted on the windshield in specific locations:

✅ Bottom 5 inches of the windshield (measured from the bottom)

✅ Top 5 inches of the windshield (measured from the top)

✅ Side edges of the windshield (left and right corners)

❌ The center viewing area is prohibited for obstructions

Proper Dash Cam Placement in Maryland

Recommended Placement Zones:

1. Behind the Rearview Mirror (Best Option)

Usually within the top 5-inch zone
Doesn’t obstruct driver’s view
Most discreet position
Optimal recording angle

2. Passenger Side of Rearview Mirror

Within side edge allowance
Doesn’t block driver’s line of sight
Easy to access for settings

3. Bottom of Windshield (Passenger Side)

Within bottom 5-inch zone
Less discreet but compliant
May have slightly different recording angle

Maryland-Specific Tip: Maryland State Police focus enforcement on the center driver-side area. Mounting behind or beside the rearview mirror is universally compliant.

What Happens If Your Dash Cam Is Improperly Mounted?

Improperly mounted dash cams can result in:

Primary offense: $50-$110 fine
Secondary issue: May affect insurance claims if footage is questioned
Court appearance: Possible if combined with other violations

Professional installation ensures proper placement and compliance. Learn more: Hardwired vs. Plug-In Dash Cam Installation.

2. Audio Recording Laws in Maryland

Maryland is a “two-party consent” state for audio recording, which has important implications for dash cams with audio recording capability.

Maryland Criminal Law Code § 10-402:

It’s illegal to record private conversations without the consent of all parties involved.

What This Means for Your Dash Cam

Recording in Public Spaces:

✅ Legal to record audio on public roads
✅ No expectation of privacy on public streets
✅ Can capture conversations with police during traffic stops

Recording Inside Your Vehicle:

⚠️ Be cautious with interior cameras (especially rideshare)
⚠️ Passenger conversations may require consent
⚠️ Consider displaying notice if recording interior audio

Recording Private Property:

❌ Cannot record audio on private property without consent
❌ Don’t record in parking garages without permission
❌ Avoid recording in private businesses

Best Practices for Maryland Dash Cam Audio

✅ Disable audio recording if you’re unsure about legality

✅ Display visible notice if recording audio in rideshare vehicles

✅ Turn on audio when interacting with police (these conversations have no privacy expectation)

✅ Inform passengers if using interior cameras with audio

✅ Review your dash cam’s audio settings regularly

3. Video Recording (Without Audio)

Video-only recording in public spaces is completely legal in Maryland with no consent requirements.

You can record:

Traffic on public roads
Other vehicles
Public spaces
Parking lots (visible from public areas)
Accidents and incidents
Police activity in public

This is why most Maryland dash cams focus on video recording.

Washington, DC has its own distinct laws that differ slightly from Maryland:

1. DC Windshield Obstruction Laws

DC Municipal Regulations § 18-2201:

DC also restricts windshield obstructions but with slightly different measurements:

✅ Bottom 7 inches of the windshield (more generous than Maryland)

✅ Top 5 inches of the windshield
