Several important changes to Idaho's DUI laws have taken effect since the original article was published. These updates focus on penalties, ignition interlock devices, and fees related to DUI offenses. The information below highlights what you need to know about these changes.

The earlier article continues further down the page.

🚔 New Penalties for Repeat DUI Offenders

On July 1, 2025, Senate Bill 1099 introduced mandatory minimum prison terms for repeat DUI offenders involved in vehicular manslaughter. The law requires at least 5 years for a second offense and 10 years for a third or further offense. This change aims to enhance public safety by holding repeat offenders accountable.

🔒 Ignition Interlock Device Requirements

Starting July 1, 2026, Senate Bill 1311 mandates that certain DUI offenders must install ignition interlock devices in their vehicles. These devices prevent a vehicle from starting if the driver's BAC is above 0.025%. Offenders must cover the installation and maintenance costs, reinforcing the law's goal of reducing drunk driving incidents.

💰 Updated Fees and Costs

As of 2026, the reinstatement fee for a driver's license after a DUI conviction is $285. The application fee for a restricted driving permit is $60. Both fees are essential for individuals seeking to regain their driving privileges following a DUI conviction.

⏰ Important Deadlines for Permits and Devices

Drivers must apply for a restricted driving permit during their suspension period. To avoid delays, it is advisable to submit Form ITD 3227 promptly. Additionally, ignition interlock devices must be installed and activated before the end of the suspension period to comply with Idaho law.

📌 Key Points to Remember

  • 🚦 Repeat DUI offenders face longer mandatory prison terms.
  • 🔑 Ignition interlock devices are now required for certain offenders.
  • 💵 Reinstatement fees and application costs have been established.
  • ⏳ Timely applications for restricted permits are crucial to avoid delays.
  • 📅 Ignition interlock devices must be activated before the suspension period ends.

💡 Tips for Navigating DUI Consequences

Reviewing your situation with an attorney is essential for understanding your options. Each case is unique and may involve different considerations.

📝 Understand Your BAC Limits

In Idaho, the legal BAC limit is 0.08% for most drivers aged 21 and older. For commercial drivers, it's 0.04%, and for drivers under 21, it's 0.02%. Knowing these limits can help you avoid DUI charges.

⏳ Apply for a Restricted Driving Permit

If your license is suspended, you may apply for a restricted driving permit using Form ITD 3227. This permit allows limited driving privileges, making it easier to fulfill work and personal commitments during your suspension.

🔒 Install Your Ignition Interlock Device Promptly

For those required to use an ignition interlock device, it's crucial to arrange for installation quickly. The device must be installed and activated before the end of your suspension period. Delays can lead to further penalties.

💵 Budget for Costs

Be prepared for costs associated with DUI penalties. This includes the $285 reinstatement fee, $60 application fee for a restricted driving permit, and ongoing costs for the ignition interlock device. Understanding these expenses can help you plan accordingly.

📞 Seek Free Assistance

If you're facing financial hardship, consider reaching out to nonprofit organizations or government resources for assistance. They may provide valuable guidance and support in navigating the consequences of a DUI.

❓ Frequently Asked Questions

🚦 What happens if I refuse a DUI test?

Refusing a DUI test for the first time results in a one-year suspension with no eligibility for a restricted driving permit. A second refusal within ten years leads to a two-year suspension with the same restriction.

🚔 Can I drive during the suspension period?

You may apply for a restricted driving permit during your suspension. This permit allows for limited driving privileges, but you must submit Form ITD 3227 and pay the application fee to obtain it.

💰 Are there penalties for excessive DUI?

Yes, a BAC of 0.20% or higher is classified as an "excessive" DUI. This carries more severe penalties, including mandatory jail time and higher fines compared to standard DUI charges.

🔒 How long do I need to use the ignition interlock device?

The ignition interlock device restriction lasts for one year from when the device is installed. During this time, it must be properly maintained and reported to the authorities.

📝 What should I do if I miss the deadline for my restricted permit application?

If you miss the application deadline for your restricted driving permit, you may face additional delays or penalties. It’s essential to contact the Idaho Transportation Department for guidance on how to proceed.

📞 Where can I get legal assistance for a DUI?

You can seek help from nonprofit organizations that offer free or low-cost legal assistance for DUI charges. The Idaho State Police and local legal aid services can provide information on available resources.

Guide to Idaho Traffic Fines



 



 

Idaho Traffic Fines


If you have been pulled over and ticketed in Idaho, you may be wondering how much money you're going to owe.  Idaho traffic fines are usually quite reasonable, especially for first-time offenders, and you may have less cause to worry than you might think.  This will be a guide for you to understand the range of fines that can be imposed by Idaho police officers and what offenses are prosecuted not as civil infractions but as much more serious misdemeanors.



 



 



It is important to keep in mind that the information in this guide, unless otherwise stated, applies to first-time offenders only, and only those who have not aggravated their offense by endangering other people or causing a traffic accident.  If you have been charged with additional traffic offenses, you may wish to consult a lawyer to understand what Idaho traffic fines you may be required to pay.



 



 



Civil Infractions Versus Misdemeanors



 



 



Most of the time, if you are pulled over for a basic traffic offense in Idaho, you will be ticketed for committing a civil infraction.  Civil infractions are less serious than criminal charges, and carry significantly less severe consequences.  While your insurance rates may go up and you will likely be assessed both Idaho traffic fines and license points, you will not go to jail if you are charged with a civil infraction.



 



 



Misdemeanors, on the other hand, carry the possibility of jail time.  While it is unlikely that a first-time offender will be given jail time for many misdemeanor offenses, habitual or repeat offenders, as well as people who are charged with very serious misdemeanors like DUI, are likely to be required to serve some time in jail in addition to paying Idaho traffic fines.



 



 



Speeding Tickets



 



 



Idaho's speeding ticket laws are relatively lenient compared to many other states.  While in some other states, speeding tickets can cost up to $1000, in Idaho they're a relative bargain, topping out at $100.  Most states double speeding tickets in work zones, even when workers are not present, but in Idaho speeding through a construction zone will only net you $50 extra in Idaho traffic fines.



 



 



You may be charged a significantly higher fine if you are charged with driving recklessly.  Reckless driving is a misdemeanor that carries a penalty of up to 90 days in jail and up to a $300 fine.  You may be charged for reckless driving for violating the speed limit by a large amount.



 



 



Other Moving Violations



 



 



Most other moving violations in the state of Idaho are penalized with Idaho traffic fines ranging from $10 to around $140, and where your fine will fall depends entirely on the officer's discretion.  Some towns may charge fines closer to the low end of the range, while other towns that depend largely on traffic fines for police funding may charge fines closer to the top of the range.  You will be assessed with Idaho traffic fines and points on your license for these civil infractions.
