After a DUI in Boise: Court Dates, IID Install, and SR-22 Filing

Idaho suspends your license administratively within 30 days of arrest if you refused the breath test or blew 0.08% or higher. This suspension runs separately from any criminal case outcome. You have 7 calendar days from arrest to request an administrative hearing with Idaho Transportation Department to contest the suspension—miss that window and the suspension takes effect automatically on day 30. Your arraignment in Ada County Fourth District Court typically occurs 2-4 weeks after arrest for misdemeanor DUI, faster if you were booked into jail. You'll receive a summons with the exact date and courtroom. First-offense misdemeanor DUI in Idaho carries mandatory minimum penalties: 2 days jail (can be suspended), $1,000 fine, 90-day to 1-year license suspension, and 1 year of SR-22 filing. Aggravated DUI (0.20% BAC or higher, minor passenger, injury, or property damage) increases minimums to 10 days jail, up to 5 years SR-22, and possible felony charges. Boise Municipal Court handles city ordinance DUI charges for arrests within city limits; state DUI charges go through Ada County Fourth District Court at 200 W Front Street. The court you're assigned determines your sentencing judge and probation officer, but SR-22 filing requirements remain identical under Idaho Code 49-1232.

Idaho requires ignition interlock (IID) for all DUI convictions, including first offense, unless the judge grants a restricted permit without IID for daytime work-only driving. Installation must occur before you can reinstate your license or begin your restricted permit period. The device stays installed for the duration of your suspension unless you qualify for early removal after 4 months on a first offense with no violations. Ada County has four certified IID providers operating in the Boise metro area: Intoxalock (multiple Treasure Valley locations), LifeSafer (Boise and Meridian), Smart Start (Boise office at 1273 S Allante Place), and Guardian Interlock (mobile installation available). Installation cost runs $75-$150 depending on provider and vehicle type. Monthly monitoring and calibration fees average $75-$90 per month. Idaho law caps total IID costs but providers charge separately for violations, missed calibration appointments, and early removal documentation. You schedule installation after your restricted permit is approved by Idaho Transportation Department, not before. Installing IID before receiving your restricted permit approval wastes money—the monitoring period starts at installation, not at permit issuance. Most Boise drivers wait 30-45 days post-conviction for ITD to process the restricted permit application, then schedule installation for the day before their permit start date.

Idaho requires SR-22 filing as proof of financial responsibility after DUI conviction. Your filing period starts on your conviction date—not arrest date, not the day you buy insurance, not the day your license is reinstated. First-offense DUI requires 3 years of continuous SR-22 filing under Idaho Code 49-1232. Second offense or aggravated DUI extends filing to 5 years. Implied-consent refusal (refusing the breath test) triggers 1-2 years depending on prior refusals. The conviction-date rule creates a gap most Boise drivers miss: you're sentenced 60-90 days after arrest on average in Ada County. If you file SR-22 immediately after arrest, you're paying for coverage during a period that doesn't count toward your required filing duration. Your 3-year clock starts when the judge signs your judgment of conviction, typically the same day as sentencing. If you're sentenced January 15, 2025, your SR-22 obligation ends January 15, 2028—regardless of when you bought the policy. Idaho Transportation Department receives SR-22 filings electronically from your insurer within 24 hours. You don't file it yourself. Your carrier transmits the SR-22 certificate to ITD, which updates your driving record. If your SR-22 lapses for any reason—missed payment, policy cancellation, switching carriers without continuous coverage—ITD receives an SR-26 cancellation notice and suspends your license immediately. The suspension remains until you file new SR-22 and pay a $25 reinstatement fee, and in most cases your 3-year filing clock resets to zero.

Most major carriers operating in Idaho—State Farm, Allstate, Geico, Progressive, American Family—will file SR-22 for existing customers after a DUI conviction but typically non-renew the policy at the end of the current term. New SR-22 policies post-DUI require the non-standard insurance market. Bristol West, Dairyland, The General, and GAINSCO write high-risk auto policies with SR-22 endorsement in Ada County. National General and Kemper also write Idaho SR-22 but availability varies by underwriting tier and whether you own a vehicle. Non-owner SR-22 policies cost $25-$50 per month in Boise for drivers who don't own a vehicle but need to satisfy Idaho's SR-22 requirement. These policies provide liability coverage when you drive someone else's car and maintain your SR-22 filing status during a suspension or restricted permit period. You'll need a standard owner SR-22 policy once you register a vehicle in your name—non-owner SR-22 does not cover a car titled to you. SR-22 filing itself adds $15-$25 to your total policy cost as a one-time or annual fee depending on carrier. The rate increase comes from the DUI conviction, not the SR-22 form. Expect total premiums of $150-$280 per month for minimum liability SR-22 coverage post-DUI in Idaho, higher if you're under 25 or carrying additional violations. Rates drop after 3-5 years once the DUI conviction ages off your motor vehicle record, but you must maintain continuous coverage during the entire filing period or restart the clock.

Idaho offers restricted driving permits (often called hardship permits) that allow work, school, medical, and family care driving during your suspension. You apply through Idaho Transportation Department after conviction, not before. Ada County Fourth District Court does not issue the permit—ITD does. You submit Form ITD 3546 (Application for Restricted Driving Privileges), proof of SR-22 insurance, IID installation if required, court judgment, and $37.50 fee. Processing takes 10-21 business days from the date ITD receives your complete application. Most Boise drivers apply immediately after sentencing to minimize the gap between conviction and legal driving. If you're sentenced on a Monday, apply that week—waiting 30 days to apply means waiting 30 days plus processing time before you can legally drive to work. The restricted permit is valid only during your suspension period and expires automatically when your full license is eligible for reinstatement. Full reinstatement after a first-offense DUI in Idaho requires completing your suspension (or restricted permit period), maintaining SR-22 for the required duration, paying all court fines and fees, completing alcohol education or treatment programs ordered by the court, and paying ITD's $285 reinstatement fee. Reinstatement is not automatic—you must apply and provide documentation of completion for every requirement. Missing one item delays reinstatement and extends the time you're paying for SR-22 coverage you can't fully use.

A first-offense DUI conviction in Boise triggers stacked costs across three systems. Ada County court fines start at $1,000 statutory minimum plus court costs, typically $1,300-$1,600 total. Alcohol education classes (victim impact panel, DUI school) add $150-$300. Public defender fees apply if appointed, usually $300-$500. Probation supervision fees run $40-$60 per month if sentenced to supervised probation. Ignition interlock installation and monitoring for 4-12 months costs $75-$150 installation plus $75-$90 per month, totaling $375-$1,230 depending on required duration. Idaho Transportation Department reinstatement fee is $285. If you requested an administrative hearing and lost, add $200 for the hearing fee. Total non-insurance costs for a first-offense DUI in Boise: $2,400-$4,000 in year one. SR-22 insurance premiums for 12 months at $150-$280 per month add $1,800-$3,360. Your total first-year financial obligation—court, IID, reinstatement, and insurance—runs $4,200-$7,360 for a standard first-offense misdemeanor DUI with no aggravating factors. Aggravated DUI, second offense, or accident involvement increases fines, jail time, IID duration, and SR-22 filing period, pushing total costs significantly higher. These figures assume you meet all deadlines, maintain continuous coverage, and complete requirements without violations or extensions.
