When you are stopped for a dwi or dui, you must be very careful with what you do and what you do not do. If you are driving under the influence of alcohol or while intoxicated and then stopped by an officer, the first thing you should do is to make a commitment that you will never make this mistake again; it can cost someone’s life. The officer is doing his or her duty by stopping your vehicle and asking you to take certain tests because by doing all that he or she is actually trying to save other people’s lives that you might otherwise have put into danger. Having said that, you have the legal right to defend yourself. Following are some of the do’s and don’ts that you must follow in this regard irrespective of whether the charges against you are true or false.
