Dash cams are legal in Maryland, but strict mounting and audio rules apply to ensure road safety and privacy. Compliance with these prevents tickets or evidence suppression in court cases.
Mounting Requirements
Devices must sit above the AS-1 line (marked on windshields) or no lower than 5 inches from the top, avoiding any driver view obstruction. Maryland Transportation Code prohibits vision hazards, so position behind the rearview mirror or on the dash.
Violations draw warnings or fines up to $500 as equipment infractions. Suction mounts are common and court-approved if compliant.
Audio Recording Restrictions
Maryland requires all-party consent for audio under wiretap laws (Md. Code, Cts. & Jud. Proc. § 10-402). Dash cams capturing private conversations without passenger knowledge risk felony charges (up to 5 years prison, $10,000 fine).
Public interactions like police stops are exempt—video and audio of officers are protected. Disable audio or notify riders to stay legal.
Court Admissibility
Footage proves fault in accidents if authenticated (chain of custody, no edits). Courts accept unaltered clips under Md. Rule 5-901, often favoring dash cam evidence over testimony.
Tampering post-crash is illegal, with penalties mirroring evidence destruction. Insurance companies subpoena compliant videos routinely.
Police Interactions
Officers cannot seize dash cams without warrants absent probable cause, per Fourth Amendment. You may record traffic stops legally, but comply with orders to avoid escalation.
Hand over footage voluntarily if requested; refusal prompts subpoenas.
| Rule | Requirement | Penalty Risk |
|---|---|---|
| Mounting | Above AS-1 line, no obstruction | Fine ($500 max) |
| Audio | All-party consent | Felony (5 yrs) |
| Evidence Use | Authentic, relevant | Inadmissible |
Best Practices
Test mounts pre-drive, use parking mode sparingly (battery drain), and label footage timestamps. As of 2026, no major changes; consult MVA for updates.
