A DUI in California is expensive and has major consequences. If you get pulled over and the officer starts investigating you for DUI, think about all of your options for a defense right away. It starts with the moment you get pulled over; not the moment you arrive at your attorney's office.
For some people, accepting a plea for a lesser charge is advantageous, particularly if the evidence against them would give them few opportunities to mount a strong defense in a court trial.
If you are facing the possibility of having a DUI charge on your record, one of the first steps you should take is contacting a DUI attorney.
