Does the taxi driver have the right to take possession of the belongings left by passengers in the car? Is it illegal to hide or not report after discovery? What's the law?

Can only be regarded as unjust enrichment. If the driver fails to return it in time or hand it in to hide it privately, he will be subject to an economic penalty of less than 1000 yuan. Whoever conceals more valuable articles with a relatively large amount shall be sentenced to criminal detention ranging from 1038 yuan to 5,000 yuan. But I don't think I know or didn't hear the broadcast. Taxi drivers are really easy to find. You can try to contact the taxi company. If you remember the taxi company or license plate number, contact the traffic control department directly.
