Dash cams are legal in Connecticut, but the following rules should be considered:
Windshield placement and visibility
No device may be attached or affixed to or hung on or in any motor vehicle in such a manner or location as to interfere with the operator's unobstructed view of the highway or to distract the attention of the operator.
To constitute a violation, there must be more than a hypothetical possibility that the driver’s vision would be obstructed or that the driver would be distracted. Proof of actual interference is required.
Audio and video recording
Connecticut is a one-party state for audio recording. This means that either the driver or another participant in the conversation may consent.
In Connecticut, it is generally legal to video record in public and in semi-public places like a truck cab, where there is little or no expectation of privacy.
However, video recording on private property (e.g., customer sites and delivery locations) without permission may be illegal, especially if footage includes people who are unaware that they are being recorded. Best practice: Dash cams should be deactivated or explicit permission obtained from the property owner or the individuals being recorded prior to video recording on private property.
Employee and driver privacy
Because Connecticut is a one-party consent state for audio recordings, fleet managers or drivers can record conversations in the vehicle as long one party, such as the driver consents. The best practice, however, is to both post a sign in the cab and inform all passengers verbally (whether customers, contractors, or employees) of audio or video recording for purposes of trust, transparency, and to avoid privacy disputes.
