Introduction This study investigated whether subjective beliefs about driving while intoxicated (DWI) consequences differ by race/gender. Method Beliefs affect driving behaviors and views of police/judicial fairness. The researchers compared risk perceptions of DWI using a survey of drinkers in eight cities in four states with actual arrest, conviction, and fine rates from court data in the same cities. Results With state arrest data as a benchmark, Black males were overly pessimistic about being stopped, whether or not actual drinking occurred, and attributed higher jail penalties to DWI conviction. That Black males overestimated jail sentences incurred by the general population suggests that they did not attribute higher jail penalties to racial bias. Arrest data did not reveal disparities in judicial outcomes following DWI arrest. Conclusions Blacks’ subjective beliefs about DWI consequences may reflect social experiences, which are not jurisdiction- or crime-specific; this is a challenge to policymakers aiming to deter DWI by changing statutes and enforcement.

Using a survey of drinkers (N=1,634), we evaluated alternative explanations of heavy and binge drinking, driving under the influence (DUI), DUI arrests, speeding citations, and chargeable accidents. Explanations included socializing, short-term decision-making, unrealistic optimism, risk preferring behavior, and addiction. Most consistent relationships were between substance use and alcohol addiction and dependent variables for (1) binge drinking and (2) DUI episodes. Respondent characteristics (age, marital and employment status, race) had important roles for DUI arrests. Drinker-drivers and those arrested for DUI are partially overlapping groups with implications for treatment and policies detecting and incapacitating persons from drinking and driving.

Purpose The purpose of this study is to classify DWI courts on the basis of the mix of difficult cases participating in the court (casemix severity) and the amount of involvement between the court and participant (service intensity). Using our classification typology, we assess how casemix severity and service intensity are associated with program outcomes. We expected that holding other factors constant, greater service intensity would improve program outcomes while a relatively severe casemix would result in worse program outcomes. Methods The study used data from 8 DWI courts, 7 from Michigan and 1 from North Carolina. Using a 2-way classification system based on court casemix severity and program intensity, we selected participants in 1 of the courts, and alternatively 2 courts as reference groups. Reference group courts had relatively severe casemixes and high service intensity. We used propensity score matching to match participants in the other courts to participants in the reference group court programs. Program outcome measures were the probabilities of participants’: failing to complete the court’s program; increasing educational attainment; participants improving employment from time of program enrollment; and re-arrest. Results For most outcomes, our main finding was that higher service intensity is associated with better outcomes for court participants, as anticipated, but a court’s casemix severity was unrelated to study outcomes. Conclusions Our results imply that devoting more resources to increasing duration of treatment is productive in terms of better outcomes, irrespective of the mix of participants in the court’s program
