7. Photograph the scene
Your Mendocino County DUI attorney will explain to you that photographs of things such as your route or a lane line you allegedly weaved over (don't snap pictures while driving!), a stop sign at an intersection which you supposedly ran through or a Mendocino County neighborhood you were driving through, an alleged illegal trailer hitch, broken tail light or other equipment malfunction (especially if it wasn't broken), etc, and the scene of the arrest and/or sobriety testing, and any damage to a vehicle or injury to you or others may be critically important later when the actual evidence has disappeared. Your Ukiah DUI lawyer would be very happy if you handed such evidence over at the beginning of your case.
