If you've been charged with a DUI, there are defense alternatives available to you. It is more common to safeguard against a drunken driving charge by assaulting the officer's observations of what occurred before the detention or scrutinizing the trustworthiness of the test, for example, the precision of the breathalyzer test. The DUI laws vary from one state then to the next, and each case has unique facts, so it is best to counsel with a Drunk Driving Attorney.
