Dash cams are fully legal in Missouri with minimal restrictions, emphasizing safe mounting and audio consent rules. Unlike stricter states, Missouri imposes no specific statutes on usage, leaving drivers broad flexibility.
Mounting Guidelines
Position cameras to avoid obstructing the driver’s view of the road, per general equipment laws (Mo. Rev. Stat. § 307.180). Common spots behind the rearview mirror or low on the dash comply; suction cups or adhesives work without issue.
Violations risk citations as vision impairments, with fines up to $100 for minor infractions. No height or size limits apply statewide.
Audio Recording Rules
Missouri follows one-party consent under wiretap laws (Mo. Rev. Stat. § 542.402), allowing audio capture if you consent—even without notifying passengers. Public police interactions remain fair game for recording.
Two-party states differ; Missouri’s leniency aids evidence collection in disputes.
Court and Insurance Use
Footage is admissible if authenticated and unaltered, proving fault in accidents via Mo. R. Evid. 901. Insurers routinely request clips, often reducing claims disputes.
Police may subpoena during investigations but cannot seize without warrants absent probable cause.
Commercial and Vehicle Rules
No bans for trucks or rideshares, though FMCSA suggests non-obstructive installs for CDL drivers. Parking mode is unrestricted but monitor battery drain.
| Aspect | Rule Summary | Penalty Risk |
|---|---|---|
| Mounting | No road obstruction | $100 fine |
| Audio | One-party consent | None specific |
| Evidence | Authentic footage OK | Inadmissible if tampered |
| Commercial Use | Permitted | FMCSA advisory |
Best Practices
Secure firmly, timestamp videos, and back up cloud. As of 2026, no regulatory changes; check MSHP manual for inspections.
