In majority of the United States the legal blood alcohol level is anything under .08. A blood alcohol level that is greater then .08 means that you are legally too intoxicated to safely operate an automobile. If you get pulled over and the breathalizer test says that your blood alcohol level is above the maximum then you are definitely going to want to seek help from a dui lawyer.  The lawyer will have the best information for you to follow when it comes to drinking and driving legalities. They may even be able to get the charges dropped depending on the situation.
