With a warrant outstanding you have two choices (beyond just waiting to get arrested at an unknown time and place): Walk into court yourself and ask the clerk to send your case into the courtroom as an "add on" or "walk in," OR retain an attorney from San Diego County (which includes Vista where my office is located) to appear in court on your behalf and have the warrant recalled. Help is available. Fees are reasonable.
Get an attorney ASAP to try and get the warrant recalled or get a bond amount at least. Your violation is not a good one. So, get on it fast before it gets you
My colleagues are correct. You want to hire an attorney to appear in court on your behalf and recall the warrant. I suggest contacting a San Diego attorney whose familiar with the court. Contact Jay Finnecy. Best of luck!
Locate an experienced criminal defense lawyer in your area, who specializes their practice in DUI DEFENSE, make an appointment, bring whatever evidence, documents or witnesses that you may have, engage in a meaningful face-to-face consultation. Each case is different. Get advice on your specific case and scenario. Most on offer free consultations. Best of luck to you.
It has been my experience that judges prefer that someone with a warrant come to court on his own than the sheriff bring him in. But you are probably in violation of your probation for serious misconduct. So you should retain a lawyer first.
