First, the above situation should be sorted out slightly and submitted to the court as a defense;
Second, attend the trial on time, put forward your own opinions, and declare that it is not your signature and the vehicle is not rented by yourself;

If what you say is true, under normal circumstances, the court will rule in your favor.
