Is it mandatory to install a dash cam in the car?

There is no mandatory requirement for dash cams, so you don't have to install one. Here is more relevant information: 1. Benefits of installation: A dash cam can continuously record driving footage, which can be useful in cases of scratches, fraud, or traffic accidents. It can serve as evidence for traffic police to determine responsibility. If you want to avoid getting entangled in traffic disputes, it is recommended to install a dash cam. 2. Steps to install a dash cam: Remove the rearview mirror casing, detach the rearview mirror, slide the two metal clips downward, disconnect the rearview mirror cable after removing the casing, unplug the connector for the anti-glare rearview mirror, disassemble the dash cam mount, align the metal clips on both sides of the dash cam mount with the slots on the rain sensor mount, and push evenly upward on both sides until it slides to the bottom.

I don't think dash cams are legally required in vehicles, but based on my experience, I strongly recommend installing one. As a long-distance driver, I was once rear-ended on the highway, and the dash cam footage directly proved the other party was at fault, avoiding insurance disputes. It can also record unusual situations around you while driving, such as crash-for-cash scams or traffic violations, providing first-hand evidence. A high-quality one isn't expensive, just a few hundred yuan, and it's easy to install—you can stick it on the windshield yourself. During normal driving, it works automatically without disturbing you, yet brings peace of mind.
