As long as it has not been a year since your arrest, they can do this. But do it the easy way. Get a lawyer NOW and have him or her arrange to add the case to the court's calendar and surrender THERE, so you don't have to post a bond at your expense. This is much better than surrendering to the police. Do it quickly before the police knock on your door with a gift of bracelets for you.
You should contact an attorney immediately, preferably one that specializes in DUI. The attorney may be able to appear for you in court so you don't have to. Additionally, the attorney may be able to determine if you have speedy trial or other issues that may get your case dismissed, reduced, or otherwise disposed of. go to the California DUI Lawyers Association to find an attorney in your area. Good luck!
