The most common mistake when faced with a DWI is talking too much. Don’t volunteer information or answer questions unless your lawyer is present. For instance, the police certainly will ask you if you have been drinking and how much. Never lie to them, but do not tell them anything. In the first place, the question is ambiguous since they do not specify a time period. Any truthful answer you give will be twisted to appear that you have lied. They will not credit any truthful answer. Simply say that you do not wish to answer and wish to remain silent until you can seek legal advice. They will argue with you and you will have to stick to your polite resolve. You should always do what any police officer tells you, but you do not have to talk or to consent to a search or anything else. This is very hard to do, the police are very good at making you nervous. Always ask if you are free to go and if they say yes, leave. If not, obey the officer, but be clear that you are not consenting but following orders.
