  1. Hawaii Strategic Highway Safety Plan:AGGRESSIVE DRIVING Dan Galanis Injury Prevention and Control Program Hawaii Department of Health 1250 Punchbowl St., Room 214 Honolulu, HI 96813 Ph: 586-5943 E-mail: daniel.galanis@doh.hawaii.gov

  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 • Definitions: Aggressive driving: 44% of crashes (250 of 574) • Speeding (“driving too fast for conditions or in excess of posted maximum”): 237 crashes • Most common criterion : includes 95% of the crashes that were defined as “aggressive” • Racing: 6 crashes • Following improperly, or improper/erratic lane changing: 5 crashes • Passing violations: 16 crashes • Reckless/erratic driving: 4 crashes

  4. Fatal traffic crashes in Hawaii, 2001-2005: Proportion related to aggressive driving, by type of crash

  5. Fatal traffic crashes in Hawaii, 2001-2005: Trends in the proportion related to aggressive driving *indicates statistically significant trend

  8. Aggressive driving in Hawaii, 2001-2005 • Total impact • 57 residents killed by in traffic crashes related to aggressive driving each year • Crashes involving aggressive drivers are the 4th leading cause of death for 16 to 40 year-old residents • 11.5% of the total of 1,719 • Cancer is 1st (14%), suicide 2nd (13%), heart disease 3rd (12%) • Crashes involving aggressive drivers are the 4th leading cause of fatal injuries for all ages • 10% of the total of 2,915

  9. Characteristics of drivers involved in fatal crashes in Hawaii, 2001-2005 *indicates statistically significant difference between aggressive drivers and other drivers

  10. Non-fatal crashes • Motor vehicle accident report (MVAR) • Criteria • Any crash resulting in injury, or >$3000 cumulative property damage • Traffic only, i.e. crashes on public roads • Excludes crashes in parking lots, driveways, military facilities, gated sub-divisions, etc. • Includes residents and non-residents, intentional and unintentional • Definitions: Aggressive driving • Value for in “Other factors” field: • “excessive speed”: 65% of aggressive drivers • “followed too close”: 31% • “improper overtaking”: 4% • Search of “Citation” field for “291C-101/102/103/104/105”, “speed”, “reckless”, “291-2”, “291C-42/43/45/50” • Only 0.6% of aggressive drivers (53 citations)
