In looking at reducing or modifying a DUI charge for a possible plea short of trial, one option in California is what is known as a "Dry Reckless."

A dry reckless is essentially reckless driving not involving alcohol.  A plea to this reduced charge will usually result in a fine and court probation, with a possibility of an alcohol education program.  However, there are significant differences with this charge and a true DUI.  It can't be used against you as a prior DUI in future charges to enchance penalties.  In addition, your license can not be suspended, and no SR22 insurance is required.  However, if you had a DMV hearing, and lost, then SR22 insurance would be required, and you would face an administrative suspension of your license.

A qualified San Francisco DUI attorney can discuss this option with you, among other alternatives to a straight DUI plea.
