What is a 2nd offense DUI in Idaho?

In Idaho, you’ll be charged with driving under the influence of alcohol or drugs (DUI) if: 
  • You’re under the influence of alcohol, drugs, or any impairing substance
  • You’re 21 or older and have a blood alcohol content (BAC) of 0.08% or more
  • You’re under 21 and have a BAC of 0.02% or more
  • You have a commercial driver’s license (CDL) and have a BAC of 0.04% or more
According to Idaho law, a DUI conviction will remain on your record for 10 years. That means if you’re arrested for another DUI violation anytime within 10 years of your first offense, your arrest will count as a 2nd DUI in the state of Idaho
But after this 10-year window has passed, your first offense will be taken off your record. So if you get caught with a second DUI after this time, it will legally count as a first offense.
Key Takeaway If you were charged with a DUI within the last 10 years and get caught driving under the influence again, you’ll be charged with a 2nd DUI offense in Idaho.

What is the punishment for a 2nd DUI in Idaho?

Punishment for a 2nd DUI conviction in Idaho varies depending on the exact circumstances. For example, an excessive BAC DUI of 0.20% or more comes with enhanced penalties
But in general, if you’re convicted of a 2nd DUI in Idaho, criminal penalties include: 
  • 10 days to one year in jail
  • Up to $2,000 in fines (or up to $5,000 if BAC is 0.20% or higher)
  • Up to one-year license suspension (or up to five years if BAC is 0.20% or higher)
  • A required ignition interlock device (IID) for at least one year
In certain situations, the courts may enforce even harsher penalties. For a 2nd DUI in Idaho, aggravating factors may lead to heftier fines and even longer jail sentences—especially under the following incidents: 
  • Refusal to submit to BAC test
  • Excessive BAC of 0.20% or more
  • Causing property damage or serious bodily injury while under the influence 
Key Takeaway A 2nd DUI in Idaho will result in a one-year license suspension, up to $2,000 in fines, a mandatory IID for no less than a year, and will
land you in jail
for 10 days.

Fees, penalty assessments, and substance abuse evaluation

While the maximum fine for a 2nd DUI in Idaho is $2,000 (or $5,000 if you’re caught with a BAC of 0.20% or more), you’ll also be responsible for paying supplementary fees and penalty assessments on top of your original fine. 
Additionally, you’ll have to undergo a mandatory substance abuse evaluation—assessed by the court—to determine what type of treatment or educational programs would assist your specific substance abuse issues. Substance abuse evaluations cost between $100 and $200 in Idaho, depending on available providers in your county.

Alternative transportation

Once you’ve paid this debt to the state, you’ll still need to consider how you’ll get around without a car. With your driver's
license suspended
for a year following a 2nd DUI in Idaho, you’ll need to rely on alternative modes of transportation. While you might be able to depend on public transportation, there may be times you might need to use ride services—which can add up quickly over one year. 

Increased car insurance costs 

Furthermore, your car insurance premium will take a hit and possibly go up by an average of $148 per month after a DUI conviction. Apply that to the state average of $1,999 per year, and you could end up paying an additional $1,776 a year for basic liability insurance
Now, let’s start crunching these numbers. After including all the required fines, fees, assessments, IID, substance abuse evaluation, and additional insurance premiums, the grand total of a 2nd DUI in Idaho after five years could potentially cost you up to $21,075.

How to avoid jail time for a 2nd DUI in Idaho

You may be able to limit your jail sentence and pay a lower fine if you have been charged with a 2nd DUI conviction in Idaho. Here’s what you should do: 
  • Bring in a good defense lawyer. Reducing a jail sentence for a 2nd DUI conviction won’t be easy, but a proficient attorney will help you maneuver through your case. 
  • Plead guilty to a “wet reckless” charge. This less severe offense will come with decreased penalties concerning jail time and the maximum fine you’ll owe. 
In some circumstances, you can take a plea bargain for a lesser “wet reckless” charge or a
reckless driving
offense involving alcohol or drugs. A wet reckless charge potentially reduces your penalties to six months in jail, a maximum $1,000 fine, and a 30-day license suspension. 
Usually, a wet reckless conviction doesn’t include a mandatory IID installation. And while you won’t be able to avoid serving jail time, your sentence will be shorter and the continuing effects of a wet reckless violation are minimized compared to the impacts of a 2nd DUI conviction.
