Are Dash Cams Legal? Does It Void My Warranty? | BlackboxMyCar


Dashboard cameras, commonly known as “dash cams,” have become increasingly popular in recent years due to their numerous benefits. Dash cams are small, discreet cameras mounted on the dashboard or windscreen of a vehicle, recording footage of the road, surrounding vehicles, and any incidents that occur during the journey. Although widely accepted in some countries, many people in the US and Canada are still unsure about their legality and whether or not dash cams will void their car warranties. This article will answer some of these questions in detail.

The Legality of Dash Cams

Dash cams are legal in both the US and Canada with some restrictions. The law varies from state to state in the US, but generally, you’re allowed to record videos of public spaces, including roads, sidewalks, and buildings. However, in most states, it is illegal to record audio without the consent of both parties. In Canada, it is legal to record video and audio as long as it’s in a public place with no expectation of privacy, but it is essential to check the specific laws governing the province or territory.

Dash Cams and Car Warranty

Many people are worried that installing a dash cam on their cars may void their warranties. It’s a common misconception that installing any aftermarket accessory will void your car’s warranty, but this isn’t true. If you install a dash cam using a plug-and-play setup, you’re unlikely to face any warranty issues. However, if you hardwire your dash cam, you may cause problems with your warranty. The Magnuson Moss Warranty Act in the US and Consumer Protections Act in Canada protect consumers against deceptive warranty practices. Therefore, if the dash cam installation resulted in a warranty denial, the manufacturer must prove that the dash cam caused the issue, and not the installation process.

Placement of Dash Cams

Dash cam placement is crucial to ensure no obstruction to the driver’s view. Careful consideration of where the dash cam is mounted is required. The dash cam should not block the driver’s view of the road or interfere with the vehicle’s airbag system. Popular dash cams usually come with a discreet design that can be easily mounted behind the rearview mirror or on the dashboard.

Benefits of Using Dash Cams

Apart from recording accidents and incidents, dash cams can enhance your overall safety on the road. With the footage from your dash cam, you can effectively train safer driving habits and create a safer driving environment. Dash cams can also provide important evidence in the event of a vehicle collision, a hit-and-run, or insurance fraud. Ultimately, dash cams can help improve the safety and security of you and your vehicle while providing peace of mind on the road.


Dash cams are legal in both the US and Canada with certain restrictions, and using plug-and-play or OBD power cable setup is unlikely to void your warranty. The careful positioning of your dash cam can ensure that it won’t interfere with any critical driving systems or obstruct your view of the road. With the above information, it’s clear that having a dash cam in your vehicle is a smart choice to promote your safety and protection on the road.
