1. How is Iowa's OWI (Operating While Intoxicated) offense defined, and what happens even without a criminal conviction?

Why: Iowa's OWI offense is defined as a BAC of 0.08% or higher, or operating with any amount of a controlled substance in your system -- your driving privilege is administratively revoked at least 180 days even without a criminal conviction.

2. What BAC level counts as intoxicated for an Iowa driver under 21, and what's the minimum revocation?

Why: An Iowa driver under 21 is considered intoxicated at just 0.02% BAC, facing at least a 60-day revocation; at 0.08% or more, an underage driver faces the same minimum 180-day revocation as an adult, with no temporary restricted license available.

3. What happens if an Iowa driver refuses a breathalyzer test?

Why: Refusing a breathalyzer test in Iowa doesn't prevent an OWI conviction and results in an automatic one-year license revocation plus a minimum $1,250 fine -- harsher than the consequences of simply failing the test.

4. What does Iowa's implied consent law require of every driver's license holder?

Why: Every Iowa driver's license holder contractually consents to a field sobriety test upon a law enforcement officer's demand under the state's implied consent law -- which also applies to non-resident drivers while they're in Iowa.

5. What does Iowa's open container law actually prohibit, and where can alcohol legally be stored?

Why: Iowa's open container law makes it a simple misdemeanor, punishable by up to a $200 fine per person, to transport any open, unsealed alcohol container in the passenger area -- open containers may legally be transported in the trunk.
