DUI Fatalities Cut in Half
Clifford J. Helander
Alcohol-involved traffic fatalities continued to decline in 1995 (-9.7%), and have dropped by over half since 1987 (-51%), according to the 1997 Annual Report of the California DUI Management Information System. Alcohol-involved injuries also declined for the ninth consecutive year in 1995 (-6.3%), resulting in a 46.3% decline over the nine-year period. Arrests for driving under the influence (DUI) also decreased again in 1995, although at a much slower rate (-3.7%) than in prior years. However, the most recent administrative per se (APS) license suspension data for DUI arrests made in fiscal year (FY)1995/96 showed a 10.7% increase over the prior year, indicating that the downward trend in DUI arrests may have ended during early 1996. Because the 45% decline in DUI arrests from 1990 (the year APS was enacted) through 1995 has been virtually mirrored by similar declines in alcohol-involved fatalities (-44%) and injuries (-42%) over the same time period, these data appear to reflect a genuine reduction in the frequency of DUI incidents in California, rather than a statistical artifact. If this relationship remains true to form, however, the very recent rise in APS actions in FY 1995/96 may forecast a reversal in trend and an unfortunate rise in the number of alcohol-involved traffic injuries and fatalities in California.
Other highlights from the 1997 DUI-MIS report include the following:
- The average blood alcohol concentration (BAC) of convicted DUI offenders in California in 1994 was .168%, or more than double the illegal per se limit of 0.08%.
- The proportion of repeat offenders among all DUI convictees continued to decline in 1994, and now stands at 31.2%.
- 13.2% of all 1994 DUI arrests were associated with a reported traffic accident, and almost half of those accidents involved injury or fatality.
- Alcohol treatment, in conjunction with license restriction, remains the most effective sanction in reducing DUI recidivism, while license suspension remains the most effective sanction in terms of overall accident reduction.
- The conviction rate for DUI offenses in 1995 is estimated to be 73%. An additional 10% of DUI arrestees are also convicted, but for lesser plea-bargained offenses including reckless driving.
