Quick answer

Use FLHSMV’s crash dashboard and finalized Traffic Crash Facts tables for Florida impaired-driving statistics. Do not combine DUI arrests, alcohol-suspected crashes and confirmed toxicology fatalities as though they are the same measure.

Impaired-Driving Categories Are Not Interchangeable

CategoryMeaningCommon mistake
Alcohol suspectedOfficer or report information indicates possible alcohol involvementCalling every case laboratory-confirmed
Alcohol confirmedEvidence supports a confirmed alcohol category under the data systemAssuming it always proves legal guilt
Drug suspected/confirmedDrug involvement coded from report or evidenceTreating every drug presence as impairment
DUI arrestEnforcement action against a personUsing arrests as the number of crashes
Impaired-driving fatalityPerson-level death associated with an impaired-driving categoryCalling it a fatal-crash count

Choose the Correct Numerator

A Florida impaired-driving page may report crashes, drivers, arrests, injuries, serious injuries, fatalities or fatal crashes. Each answers a different question. One crash can involve multiple drivers, more than one substance and several injured people. Adding overlapping categories can double-count the same crash.

Why Preliminary DUI Crash Numbers Change

Alcohol and drug data may depend on breath, blood or urine testing, medical records, toxicology, death investigation and later record matching. A crash can initially be coded as suspected and later confirmed, changed or removed from a category. Finalized annual reports are better for trend analysis; dashboards are useful for current monitoring when labeled correctly.

Florida DUI Law and Crash Statistics Answer Different Questions

A crash-data category is not a criminal conviction. Florida DUI law addresses driving or being in actual physical control while impaired or with an unlawful alcohol level. An individual case requires evidence and due process. Aggregate statistics should never be used to declare a specific person guilty.

Drug-Impaired Driving

FLHSMV emphasizes that marijuana, controlled substances, prescription medication and over-the-counter medication can impair reaction time, memory, coordination, concentration and distance perception. The presence of a substance and the degree of impairment are separate analytical questions, particularly when a substance can remain detectable after its strongest effects have passed.

Do not add alcohol and drug totals blindly. A crash involving both can appear in more than one category.

Prevention and Emergency Response

  • Use a sober driver, taxi or ride service before drinking begins.
  • Do not drive after using a drug or medication that affects alertness or coordination.
  • Call *FHP (*347) to report a dangerous or impaired driver when it is safe to do so.
  • Call 911 for an immediate emergency.
  • Never confront or follow a suspected impaired driver.

Checklist for Reporting Florida DUI Statistics

  1. Identify the exact impaired-driving category.
  2. State whether the value is suspected, confirmed, preliminary or finalized.
  3. Separate crashes, drivers, fatalities and arrests.
  4. Check for overlap between alcohol and drug categories.
  5. Use the same definition across all years.
  6. Avoid turning a statistical category into a legal conclusion.
Found outdated information?

Impaired-driving categories can be revised after toxicology and may overlap. Send the exact category, year and report version with corrections.
