Just remember, you are within your rights to record video on a public road, as long as you do not cause an obstruction, for example, by stopping in the middle of the road to record an arrest.
There are two other main issues when it comes to the legality of Dashcams in the USA, first in some States you must have all party consent to record audio and this is an issue as most Dashcams have audio recorders built in. However, Amacam Dashcams can all be muted and therefore, not record any audio in your vehicle, meaning you do not need to remember to ask each individual who gets into your car to sign a waiver. The Dashcam will simply record the visual image which is legal on a national level.
Secondly, many States have strict laws regarding obscuring your field of vision. Suction cup mounts have been outlawed or tight restrictions placed on the position of any equipment on your windscreen and very meticulous officers may write a ticket if they feel your view has been impacted negatively.
Very importantly, Amacam Dashcams are miniature and can fit neatly behind the rear view mirror and, therefore, do not cause an obstruction to the driver’s view. *
A summary of the States where the law may prohibit or have restrictions is the end of this article. It is not definitive as the law is open to interpretation which has caused much of the confusion about the place of Dashcams and the law.
In summary, you can record video anywhere in public on your Dashcam, you can record audio in some States but with an Amacam you don’t have to, you can just mute it and Amacam Dashcams are small enough not to obstruct your view as you can easily position them behind your rear view mirror, so the police shouldn’t have an issue with them, but please check.
*Amacam accept no responsibility if you break the law, please check your State law carefully and remember that the law differs as you cross State lines.
