1, b Failure to receive a summons will not affect the hearing. Even if B is not present at the hearing, the court can make a judgment as long as there is evidence to support it.
2. The address of B can be found through industrial and commercial registration.
3. If you really can't find Company B, you can sue Company C for joint liability, including the insurance company he underwrites, so that the law can help you recover your losses and prevent him from not cooperating.
4. If the truck is fully responsible, you can directly apply to C Insurance Company for compensation within the insured amount. If the compensation exceeds the insured amount, you can apply to A Owner and B Company for compensation (it can be traced back to the company where the vehicle is located without looking for a separate compensation from the owner). Most traffic cases are like this, in order to minimize their own losses. In case the owner is poor, the company behind it can bear joint and several liability compensation. No matter the amount is 1 yuan, the court will support it as long as it is reasonable. You can rest assured that the laws of China are credible. If the other party does not execute, it may apply to the court for compulsory execution.
