  2. Overview of presentation • Fatal traffic crashes (FARS data) • Definitions • Overall prevalence • Trends, county comparisons • Other factors • Time, day of week, driver age • Driver profiles • Non-fatal traffic crashes (MVAR/DOT crash data) • Definitions • Overall prevalence • Trends, county comparisons • Other factors • Driver profiles

  3. Fatal crashes • Fatal crash/FARS data • Traffic only, i.e. crashes on public roads • Excludes crashes in parking lots, driveways, military facilities, gated sub-divisions, etc. • Unintentional in nature • Excludes suicides (1 crash), deaths of undetermined intent (7 crashes, 1% of total) • Excludes 37 crashes (6%) that did not involve a Hawaii resident fatality • Alcohol-related • BAC > 0.01% for any driver involved in the fatal crash, or refused test • Most (82%) alcohol-related crashes had at least one driver 0.08% or more • Alcohol related ~~ intoxicated • Drug-related • Positive results for any driver involved in the fatal crash • Positive for narcotic, depressant, stimulant, THC, or hallucinogen • THC (13%) • Stimulants (10%) • methamphetamine (7%), amphetamine (5%)
