Understanding Dash Cam Regulations in Massachusetts

Dash cams, also known as dashboard cameras, have grown popular for their potential to protect drivers. They can provide crucial video evidence in the event of an accident, theft, or insurance dispute. However, as with any piece of technology that involves recording, there are specific regulations in Massachusetts that govern their use. This article aims to shed light on these regulations, ensuring you use your dash cam responsibly and within the bounds of the law.

Dash cams offer several advantages for Massachusetts drivers. They can:

  • Provide Evidence in Accidents: Dash cam footage can be vital for establishing fault and protecting your rights in case of a car accident.
  • Deter Theft and Vandalism: The presence of a dash cam can act as a deterrent to potential thieves or vandals.
  • Document Road Incidents: Footage is useful in reports for insurance companies or even to capture unexpected events on the road.

It’s important for drivers in Massachusetts to understand the laws surrounding dashcam use to avoid potential legal complications.

Massachusetts Dash Cam Laws: Key Points

  • Windshield Mounting Restrictions: Massachusetts law prohibits mounting any “non-transparent material” on the windshield. This includes most dash cams, as they’re considered to obstruct the driver’s view.
  • Side Window Mounting Regulations: You can mount a dash cam on your side windows, but it must not reflect more than 35% of visible light. This regulation is in place to prevent driver distraction.
  • Audio Recording Laws: Massachusetts is a “two-party consent” state regarding audio recording. This means you cannot record conversations inside your vehicle without the explicit consent of all parties involved.
