1. What happens immediately when a Missouri driver is stopped with a BAC of .08% or more?
Why: Missouri's administrative action for a .08%+ BAC (.02%+ for a minor) takes the license immediately, with a notice that it will be suspended or revoked in 15 days -- the notice includes a 15-day temporary driving permit, and the driver can request a hearing or an immediate 90-day Restricted Driving Privilege.
2. What is the license consequence of a second Missouri DWI conviction within five years of the first?
Why: A first Missouri DWI conviction brings a 90-day suspension; a second conviction within five years escalates to a one-year license revocation -- though only convictions dated August 28, 2009 or later count toward the state's separate five-year denial track.
3. Under Missouri's Abuse and Lose Law, how long does a driver under 21 lose their license for an alcohol-related traffic offense?
Why: Missouri's Abuse and Lose Law takes a driver's license for 90 days if they're under 21 and commit an alcohol-related traffic offense, possess or use alcohol or drugs while driving, alter a license, or (if under 18) commit a second alcohol-possession offense.
4. How does the license suspension for a Missouri Minor in Possession (MIP) offense escalate with repeat offenses?
Why: A Missouri driver 15-21 convicted of MIP or another intoxication-related offense faces an escalating suspension: 30 days for a first offense, 90 days for a second, and a full one-year revocation for a third.
5. What happens to a Missouri driver's license if they refuse a chemical BAC test when an officer requests one?
Why: Refusing a chemical BAC test in Missouri brings an automatic one-year license loss -- a longer, harsher consequence than simply failing the test.
6. How long must a Missouri driver with more than one intoxication-related contact keep an ignition interlock device installed?
Why: Missouri requires at least six months of ignition interlock use from the reinstatement date, with the last three months free of violations -- failing to maintain it re-suspends driving privileges and adds a $20 reinstatement fee.
7. How many points in how much time triggers a full one-year license revocation in Missouri?
Why: Missouri revokes a license for a full year at any of three thresholds: 12 points within 12 months, 18 points within 24 months, or 24 points within 36 months. A lower threshold -- 8 or more points in 18 months -- brings only an escalating suspension (30/60/90 days), not a revocation.
8. How do points come off a Missouri driver's record after their license is reinstated?
Why: At reinstatement, Missouri resets a driver's point total to four; from there, the remaining points drop by one-third after a violation-free year, by one-half after two years, and to zero after three years.
9. What happens if a Missouri driver fails to appear in court for a traffic ticket and doesn't pay within 30 days?
Why: Missouri's Failure to Appear in Court for Traffic Violations (FACT) process gives a driver 30 days to pay before the court notifies the Driver License Bureau -- once notified, driving privilege is suspended right away, and reinstatement needs proof of payment plus a $20 fee.
10. What are Missouri's minimum liability insurance requirements, including the mandatory uninsured motorist coverage?
Why: Missouri's minimum liability coverage is $25,000 per person/$50,000 per crash for bodily injury and $25,000 per crash for property damage (25/50/25) -- and state law separately requires $25,000/$50,000 in uninsured motorist bodily injury coverage on every policy.
11. How does Missouri's reinstatement fee for a no-insurance suspension change with repeat suspensions?
Why: A Missouri no-insurance suspension carries an escalating reinstatement fee: $20 for a first suspension, $200 (plus a 90-day suspension) for a second within two years, and $400 (plus a full year's suspension) for a third or later one -- all three tiers require three years of proof of insurance on file.
12. How can a Missouri vehicle owner self-insure instead of buying a standard liability policy?
Why: Missouri lets a vehicle owner self-insure by owning more than 25 vehicles and showing they can cover damages, or by filing a $75,000 bond, certificate of deposit, or other security with the Department ($150,000 if it's a real estate bond).
