There is no way to answer that question without more information. Was there any injury? Do you have any priors? How bad was the damage? What was your reading? And so on . . See a good lawyer and find out what they say since I practice in NY. Good luck.
In California, a first time DUI does not usually involve jail time. The accident may require jail time depending on the jurisdiction, but most likely it will just result in a restitution hearing where the driver will be required to pay for the damages.
