In this introduction, we’ll be discussing the basics of Idaho DUI law, how the law works, and the possible outcomes of violating the law.

What is DUI?

DUI, or Driving Under the Influence, refers to operating a motor vehicle while being influenced by alcohol, drugs, or any other substance that impairs the driver’s judgment and responsiveness. Alcohol is the most commonly abused substance among drivers. They are likely to cause accidents, fatalities and less attentive to traffic rules and regulations.

Idaho DUI Legal Limit

In Idaho, the legal limit for blood alcohol concentration (BAC) levels for anyone driving a motor vehicle is 0.08% or higher. If you are under 21 years of age or are a commercial driver, the permitted BAC limit is much lower – 0.02% or more. This means, an underage driver, anyone who has a CDL, and are driving a commercial vehicle while under the influence will receive severe stricter penalties compared to regular drivers.

Consequences for First Time DUI Offense

In Idaho, the penalties for the first-time DUI offender include:

Offense Penalties
First-Time DUI Offense Up to $1,000 fines, suspended licenses for a minimum of 90 days (maximum of 180 days), and up to six months in jail (minimum two days mandatory jail) and unable to get CDL for one year
BAC level above .20 percent (Aggravated DUI) Up to $2,000 fines, mandatory prison time ranging up to five years, and a minimum license suspension for a year minimum (maximum five-year suspension, no restriction on which type of vehicles)

Note: The penalties against DUI become more severe with each subsequent offense.

The Strengths and Weaknesses of Idaho DUI Law

Strengths of Idaho DUI Law

Idaho’s DUI laws have received nation-wide acclaim for their strictness, heavy fines, and mandatory jail time. Some of the law’s strengths are as follows:

Decrease in DUI Accidents

The implementation of strict DUI laws has led to an annual decrease in the number of DUI accidents. As per the Idaho State Police’s report, in 2015, there were 1,508 alcohol-related collisions resulting in 66 fatalities, while in 2019, there were 876 alcohol-related collisions, with 46 fatal DUI accidents.

Mandatory Ignition Interlock Devices

Idaho law mandates that all persons convicted of a DUI offense must install an ignition interlock device (IID) in their vehicles. The IID helps to ensure individuals do not drive under the influence of alcohol or any other impairing substance. Research has shown a significant reduction in DUI recidivism rates with the installation of an IID.

Zero Tolerance for Underage DUI

Idaho has a zero-tolerance policy for underage driving under the influence. It is illegal for any person below 21 years of age to operate a motor vehicle with a BAC above 0.02%. Any underage individual caught violating the law faces severe consequences, including a license suspension of 180 days, $500 fines, and mandatory community service.

Increased Enforcement

Idaho enforces the strictest DUI laws and ensures that all individuals who violate these laws face the appropriate consequences. It has implemented sobriety checkpoints, which are proving to be effective in detecting and eliminating DUI offenders. These checkpoints have played a significant role in dissuading drivers from driving under the influence of intoxicants.

Weaknesses of Idaho DUI Law

Like any legislative framework, the Idaho DUI law also has some weaknesses. Below are a few of the weaknesses you’ll want to keep in mind:

Flawed Blood Testing Procedures

The blood, breath, or urine tests can potentially yield false results due to some external factors such as ketosis, diabetes, kidney or liver disease. A proven medical issue can create altered results where someone may register above the .08 percent limit even though they were not drinking. Additionally, the police needs to follow specific protocols while administering these tests and while blood results may be reliable, urine and breath tests is known to have high chances of error.

Subjectivity of Field Sobriety Testing

Field sobriety testing is subjective, and a person who is stressed, anxious, or unwell can easily fail these tests. Additionally, conditions such as obesity, vertigo, or past injuries, could affect the individual’s balance. With these subjective testing methods, it is easy to misinterpret the behavior of an individual who is genuinely not under the influence with those that are.


Q: How long does a DUI stay on your record in Idaho?

A: A DUI conviction generally remains on your driving record in Idaho for ten years.

Q: What is the implied consent law in Idaho?

A: Idaho has an implied consent law, which means all drivers have given their implied consent to be subjected to chemical testing when pulled over for suspicion of DUI. Refusing to take these tests is admissible against you in court.

Q: Can an out-of-state DUI conviction affect a driver’s license in Idaho?

A: Yes, Idaho’s Driver’s License Compact permits other states’ Departments of Motor Vehicles to notify Idaho about a driver’s DUI conviction in another state.

Q: Can a DUI Attorney help in avoiding a DUI conviction?

A: Yes. They can assist in analyzing the evidence against you, building a solid defense, and possibly get lesser charges or sentence.


Idaho DUI law ensures that anyone who violates these laws shall face the appropriate consequences. In summary, the strengths of the Idaho DUI laws include decreased DLU statistics, mandatory IID installations, zero-tolerance for underage DUI, and increased enforcement. However, some weaknesses of the Idaho DUI law include the flawed blood testing procedures and subjective field sobriety testing.
