First Offense Penalties in Idaho
Implied Consent & Test Refusal
Like all 50 states, Idaho has an implied consent law — by driving on Idaho roads, you've already agreed to submit to a chemical test (breath, blood, or urine) if an officer has probable cause to believe you're impaired.
Refusal Penalty
1-year license suspension
