Driving in Idaho means you've already agreed to be tested for alcohol or drugs if an officer suspects you. Refusing has its own penalties, and getting your license back after a suspension takes fees and sometimes years of proof of insurance.
Implied consent
Anyone who drives or is in physical control of a vehicle in Idaho has consented to a BAC or drug test if suspected of driving under the influence (Idaho Code 18-8002).
Handbook p. 126 ↗Civil penalty for refusing the test, in addition to a license suspension
Handbook p. 126 ↗Test refusal suspensions
| Refusal | Suspension |
|---|---|
| First (if court upholds officer) | One year, absolutely no driving |
| Second within 10 years | Two years, absolute |
Know the rule
Refusal penalties are in addition to any penalty for a DUI conviction.
Handbook p. 127 ↗Know the rule
A suspended driver may qualify for a restricted permit to drive to work, medical treatment, etc. Apply at ITD in Boise if ITD suspended you, or to the convicting court if a court did.
Handbook p. 127 ↗Ignition interlock device
A device that requires a breath sample to start the vehicle; it won't start if alcohol is at or above a preset level. The driver pays for installation, maintenance, and monthly fees.
Handbook p. 127 ↗Know the rule
An interlock is mandatory on all administrative license suspensions, starting when the suspension ends. After a DUI conviction it's required on any vehicle you drive unless the court orders otherwise.
Handbook p. 127 ↗Reinstatement fee to get privileges back from ITD, depending on the suspension (multiple suspensions can mean multiple fees)
Handbook p. 127 ↗Proof of financial responsibility (SR-22)
| Reason | How long |
|---|---|
| Serious offense (reckless driving, DUI, etc.) | Three years |
| No-insurance violation, first offense | One year |
| Second no-insurance offense within five years | Three years |
Put it into practice
You're pulled over on suspicion of DUI and refuse the breath test. You face a $250 civil penalty and, if the court upholds the officer, a one-year suspension with no driving at all, on top of any DUI penalties.
