When most people think of a case of driving under the influence of drugs (DUI, for its acronym in English), usually think of driving under the influence. In most cases, this is exactly what it means, but it is also important to note that may be a case of driving under the influence of alcohol or drugs by smoking marijuana. This law applies to various drugs, not just alcohol. It is not allowed to drive a motor vehicle of any kind while under the influence of alcohol or drugs.

Most laws on driving under the influence of drugs and penalties vary by state.

  • Blood alcohol concentration of 0.08

There is a law that, although it depends on each state, is similar in each. This is the law about blood alcohol concentration (BAC acronym). This is a number that determines the amount of alcohol in the bloodstream at a given time. There are several ways to measure it; however, in breath alcohol tests they are the most used.

In each state, the limit for drivers who have the age required by law to drink (21 or older), is 0.08. If, after being stopped by a traffic officer reaches or exceeds this limit, it will be stopped.

There are some exceptions to this rule. On the one hand, drivers who do not have the age required by law to consume alcohol may be arrested even when any amount of alcohol in blood is detected. First, they may be detained because they cannot drink; furthermore, they could receive a penalty for driving under the influence of alcohol or drugs even when blood alcohol concentration of 0.02 to 0.07 out or any other level below the legal limit, unlike what would happen with a driver majority.

Another exception applies to drivers of commercial vehicles and professional drivers. In all states, the limit for these drivers are only 0.04.

  • Fines and in each state

In different states, fines and penalties vary. For example, if you initiate an action for driving under the influence of alcohol or drugs in Maryland, you will lose your license for a period of nine months, if it is their first offense. Also you have a fine of between $ 600 and $ 1000, and could be sentenced to one year in prison (although this is not mandatory), in addition to attending courses on alcohol.
