If the footage is directly related to a driver’s car accident case, it is usually allowed in court for supporting or disproving evidence collected at the scene of the crash. Note: Drivers who are plaintiffs need to realize that dash cam footage can be used against them if the fault is not apparent, and the recorded video can be subpoenaed to contest the personal injury claim. For example, one plaintiff sued a Tennessee-based trucking company for $150,000 in damages, claiming the defending truck driver had swerved out of his lane and into the side of the plaintiff’s car, causing the damage. But, because the trucking company had dash cams installed into each truck of its fleet before the accident, video that was captured clearly showed instead the plaintiff changing lanes and smacking directly into the front corner of the truck and the truck remaining in his lane, not causing the accident at all. Keep in mind, too, that state laws which are frequently updated and outline the legal placement of a dash cam need to be followed. This is also for a driver’s safety purposes. Footage retrieved from a dash cam that is found to obscure your view may not be legally admissible. Requirements for a dash cam placed in the middle or driver’s side of the windshield are: The dash cam cannot block more than five square inches. The dash cam cannot be installed in the zone of airbag deployment. The passenger side of a windshield dash cam requirements include: The dash cam cannot block more than seven square inches. The dash cam cannot be installed in the zone of airbag deployment.
