Hardship license IID requirements vary widely by state and trigger. First-offense DUI in
Arizona requires six months of interlock use;
Florida requires six months for first offense but two years for refusal cases.
California applies tiered durations: six months for first offense, one year for second, two years for third.
Multiply your state's mandated months by your actual monthly cost including calibration and service fees. A six-month Florida requirement at $130/month totals $780 before installation and removal. A two-year California requirement at $150/month totals $3,600. Most drivers underestimate total program cost by 30-40% because they calculate rental only and ignore the service and calibration stack.
Some states allow early removal if you maintain a violation-free period.
Texas allows petition for early removal after half the mandated period if you have zero failed tests and zero missed calibrations.
Ohio requires full-term compliance with no early-exit option. Know your state's rules before assuming you can reduce total cost by maintaining a clean record.
