Mississippi DUI Laws - Everything You Need to Know

Alcohol and drugs never go well with driving. Even if you think you can go home safely, there’s no guarantee of that. 

If that doesn’t make you avoid drunk driving, then surely the Mississippi law will. 

There are strict DUI laws in the state. And if you break those laws, expect harsh penalties. 

Today, we’re going to tell you everything you need to know about Mississippi DUI laws and penalties. We’ll also answer some of the most frequently asked questions about DUI. 

So let’s dive right in!

DUI Laws in Mississippi

Mississippi DUI Laws

There are several laws related to DUI in Mississippi. These include:

  • Illegal BAC levels
  • Zero Tolerance Law
  • Implied Consent Law
  • Drugs and Driving 

Let’s take a close look at each one. 

Illegal BAC Levels

Blood Alcohol Content (BAC) levels determine the amount of alcohol in your system in terms of its volume per mass of blood. Now, your BAC level is used to identify whether you have been drunk driving or not.

In Mississippi, the illegal BAC levels are: 

  • 0.08% and above for drivers aged 21 and above
  • 0.04% and above for drivers that hold a commercial license

Does that mean that you won’t have a DUI if your BAC level is lower?

Technically, yes. However, you won’t know your BAC level until you are pulled over by a police officer. This means that you are already showing signs of drunk driving. 

 To be safe, just don’t drink and drive

Zero Tolerance Law

Since the legal drinking age in Mississippi is 21, you can expect stricter laws for underage drinkers. 

Called the Zero Tolerance Law, it states that the illegal BAC level for minors (below 21 years old) is at 0.02%. This means that the smallest amount of alcohol in your blood will already be a DUI. 

And yes, harsher penalties are given to minors when they are charged with DUI. 

Implied Consent Law

The Implied Consent Law, as its name suggests, implies that if you are operating a motor vehicle on any Mississippi road, you have already given consent to subject yourself to a breath, blood, or urine test for your BAC level. 

So if you are pulled over by a police officer and asked to submit to a BAC test, you are required to comply. 

However, know that you can refuse to take the test on the spot. Instead, you can get tested by a private institution. 

Drugs and Driving

Unlike alcohol, drugs don’t have a metric to identify how “drugged” you are to be convicted of a DUI. 

In general, you can be convicted of a DUI if it can be proven that your driving ability is impaired due to the drugs that you took. And yes, even if you are taking prescription drugs, this doesn’t protect you from getting convicted.

In other words, all kinds of drugs, illegal or legal, prescribed or not, can impair your driving. If it’s proven that they have, you will get a DUI. 

DUI Penalties in Mississippi

As we said, the DUI penalties in Mississippi are very harsh. 

And for good reason. 

Check out the penalties for each offense of DUI for non-commercial drivers that have a BAC level of 0.08% and above:
