When you're charged with drunk driving, the consequences you may face vary. A DUI in Montana becomes a felony if you have already had three convictions before. Observe safety while on the road to stay out of trouble and get legal help when you need it to fight your case.

According to the National Highway Traffic Safety Administration, around 32 people in the US lose their lives each day due to drunk driving crashes. Many victims end up with severe injuries too that affect their lives in many ways.

These are among the top reasons why there are strict laws for traffic violations in Montana.

What Is the Most Common Punishment for a First-Time DUI?

24 consecutive hours to 6 months in jail. You might also have to pay a $600 to $1,000 fine depending on what the judge decides.

When you get a DUI, and one or several of the passengers who were in your car are under 16, the punishment increases. You'll have to go to jail for at least 48 consecutive hours and pay a fine of $1,200 to $2,000.

Don't think of a first DUI as just another traffic ticket. Driving while drunk impairs your thinking. You may cause an accident even if there isn't bad weather or poor road conditions.

Do You Always Go to Jail for a DUI?

In most cases, yes. The state statutes in Montana impose mandatory imprisonment for many DUI convictions. Being in jail might affect your mental or physical health.

You might be able to avoid it once you present the evidence to prove this. If you end up leaving jail before your sentence is over, the judge will set some rules for you. They can ask you to:

  • Participate in DUI courts
  • Join a 24/7 sobriety and drug monitoring program
  • Complete your jail term if you break the rules they set

Understanding What Can Make Drunk Driving a Felony in Montana

Learning what makes a DUI a felony in Montana can help you avoid finding yourself in such situations. Consider always getting legal so you can start building your case early.

A Fourth or Subsequent DUI

Any DUI offense that comes after your third one will be considered a felony. Prosecutors look at your records to determine which penalty to impose.

You'll be facing up to 5 years in prison when you have a felony DUI. The penalties also go up to $10,000.

Don't think of your old DUIs as something minor. They can all lead to a legal escalation later on. After you talk to a Kalispell lawyer, they'll help you know the right steps to take when facing your fourth DUI.

Work with them to check if the officers who stopped you or came to the accident scene also followed the right steps when gathering evidence.

A Blood Alcohol Concentration (BAC) of 0.16 or More

If you're a regular adult driver, the legal BAC limit is 0.08. Anything beyond that counts as drunk driving. You might be facing a felony charge if your BAC is double the legal limit or more.

Driving while having a child passenger makes your case more critical. Find out about the penalties you'll face depending on:

  • Whether it was your first, second, or third offense
  • If you were already required to use an ignition interlock device
  • Whether you caused injuries

Montana takes highway safety quite seriously. Even if it's your first time driving while drunk, the prosecutor can decide to upgrade your case to a felony.

Driving with a BAC of 0.16 or more is often considered an aggravated DUI. Other details about your case will determine how the prosecutor chooses to charge you.

Driving With a Suspended License or With a Revoked One

Being unable to drive because your license was canceled or suspended can complicate your life. You might need your car to:

  • Get to work
  • Take your kids to school
  • Make a living

Even if you're in such a situation, pay attention to the advice you get during legal representation. Don't drive if your license is suspended or revoked. It will only complicate issues if you later have a DUI case.
