Is there any possibility I go to jail if I was charge car accident and DUI arrest?

You can go to jail if a misdemeanor for up to 6 months. Were there people hurt in another car? You need a lawyer.

If the accident was a result of your DUI, you can be charged with felony DUI which has a potential jail sentence of 1 to 3 years. Hire an attorney.

Every crime carries possible time. That what crime means. Your felony DUI carries a year or more in state prison. Upon arrest police have three court days to bring you to Arraignment, where the judge will determine if bail or OR will be granted. When charged with any crime, the proper questions are, can any evidence obtained in a test, search or statement be used against you, can you be convicted, and what can you do? No amount of free 'tips and hints' from here or elsewhere are going to effectively help in a legal defense. If you don't know how to represent yourself effectively against an experienced prosecutor intending to convict, then hire an attorney who does, who will try to get a dismissal, charge reduction, diversion, programs, or other decent outcome through motions, plea bargain, or take it to trial if appropriate. A little free advice: If arrested for DUI, whether alcohol or drugs, then upon release from jail or booking, the defendant is given documents that include a notice that he has only ten days to file a request with DMV for a hearing on an appeal of the automatic suspension of license imposed by DMV upon arrest. That is separate and runs consecutively with any suspension that may be imposed by DMV or the court upon conviction. Contact DMV and do so timely if you think you have grounds for appeal, then appear at the scheduled DMV appeal hearing to present your supporting evidence and witness testimony. If you don't know how to do these things effectively, then hire an attorney that does.
