Prohibitions against impaired driving in New Hampshire

In New Hampshire, as in other states, it is illegal to drive while under the influence of something that could impair your ability to drive in a safe manner. One of the most common ways that this law is applied is when it comes to drunk driving. While it is possible to consume some alcohol and then drive legally, you are not allowed to do so if you are over the legal Blood Alcohol Concentration (BAC), which is 0.08.

BAC can be measured in a few different ways. The most common way is through the use of a breath test, though blood tests can also be used.

However, it is important to note that drunk driving is not the only thing that is prohibited. It is also illegal to drive while impaired by or under the influence of the following:

-- Controlled drugs that are under heavy regulation or that have been made illegal.-- A prescription drug that inhibits the ability to drive a motor vehicle.-- An over-the-counter drug that does the same.-- A chemical substance that comes from a natural source.-- A chemical substance that is synthetic and manufactured.

The laws also extend beyond mere passengers cars, motorcycles and other such vehicles, as they include boats and other craft that can be operated on the water. The use of any of these vehicles while under the influence of any of the aforementioned substances could lead to an arrest.

After an arrest, it is very important that you know all of your legal options as you and your legal team set up a defense or plead your case.
