3. Is it worse if my prior was recent?
Yes in most cases. If there are no viable defenses in your current case, then additional hurdles will likely be present such as a violation of probation charge, and possible remand to jail or tougher conditions of release during the case due to heightened Mendocino County court concerns with community safety if the repeat offender is out on bail or "own recognizance."
Even if the blood alcohol levels alleged in the current case are below .08%, the Santa Rosa DMV may act to suspend a driver license for a year (with no possibility of any work or other driving privileges) if a new DUI arrest occurred while the driver was on probation for a prior conviction. However it may still be possible to obtain an ignition interlock restricted license after a relatively short wait period, pursuant to new laws. Consult with a Ukiah DUI lawyer about your specific case.
