The effect of victim impact panels on DUI/DWI rearrest rates: a twelve-month follow-up.

OBJECTIVE: Various interventions have been implemented as components of sentencing for driving under the influence of alcohol. This study assessed the effectiveness of the Victim Impact Panel (VIP) in reducing the probability of an offender being rearrested for drinking and driving. METHOD: The study was conducted in an urban/suburban county in the Southeastern United States. Rearrest rates of DUI offenders who attended a VIP presentation as part of their sentencing (n = 404) were compared with an equivalent comparison group (n = 431) who did not have the VIP presentation. Arrest records of offenders were searched and rearrest rates (%) were calculated for the periods 0-6 months, 7-12 months, and 0-12 months after the arrest. RESULTS: Chi-square cross-tabulations indicate that rearrest rates were lower for the VIP group than the comparison group in all categories. Three categories where the differences were significant and of the greatest magnitude were white men, ages 26-35 years, and one prior DUI arrest. Additionally, logistic regression was used to compare the importance of specific independent variables on rearrest. Whether or not a subject was in the VIP group was the most powerful contributor to the results. CONCLUSIONS: After considering alternative explanations for the results, we conclude that the VIPs can be a cost-effective way of reducing the probability of rearrest in DUI offenders. When costs of DUI in human misery and dollars are considered, the potential benefits of large-scale implementation of VIP programs appear to be well worth the effort.

The Alberta Interlock Program: the evaluation of a province-wide program on DUI recidivism.

AIMS: This study was designed to determine the efficacy of alcohol safety interlocks in reducing recidivism among first and second driving-under-the-influence (DUI) offenders. It also evaluates the overall effectiveness of interlock programs where typically only a small portion of DUI offenders elect to install interlocks. DESIGN: The driving records of DUI offenders participating in interlock programs for 6 months for first offenders and 2 years for second offenders were compared with similar offenders who chose not to participate. SETTING: A province-wide program in Alberta, Canada. PARTICIPANTS: Records of 35,132 drivers convicted of DUI between 1 July 1998 and 30 September 1996 were analyzed MEASUREMENTS: Repeat DUI offenses during and after the interlock period. FINDINGS: While the offenders had interlocks on their vehicles, DUI recidivism was substantially reduced. Once the interlock had been removed and the participants had been reinstated, their DUI rate was the same as other offenders indicating that the interlock reduced recidivism while in place. Because only 8.9% of eligible drivers elected to participate in the interlock program, the program did not significantly increase the overall effectiveness of the province's management of DUI offenders. CONCLUSIONS: Interlocks are associated with a major reduction in DUI recidivism while on the vehicle of the offender. However, because few offenders elect to participate, the program produces only a small (5.9%) overall reduction in the recidivism rate of all DUI offenders.

Driver behaviour of ethanol-impaired non-vehicular trauma victims.

During a recent 12-month period, a group of patients injured from causes other than road accidents were studied. Twenty-four patients with no evidence of alcohol impairment served as controls for another group of 24 patients with a blood alcohol concentration of greater than 100 mg%. Examination of public records revealed that the alcohol-impaired group had committed more serious traffic violations, including reckless driving, crashes causing bodily injury, and property damage. Eleven of the 24 alcohol-impaired subjects had a total of 18 previous citations for driving under the influence of alcohol while there were none in the control group (P less than 0.001). Alcohol-related non-vehicular trauma is highly predictive of alcohol-impaired driving behaviour.

The effect of drinking and driving interventions on alcohol-involved traffic crashes within a comprehensive community trial.

The Drinking and Driving Component, one of five elements of the Community Trials Project, involved the implementation of a special drink driving countermeasure in the three experimental communities, one in Northern California, one in Southern California and another in South Carolina. This intensified enforcement of driving under the influence (DUI) was designed to deter potential drinking drivers by increasing their perception of the risk of being arrested leading to a reduction in the consumption of alcohol before driving. See component detailed description in Voas (1997, this issue). The evaluation found that media advocacy training and technical assistance resulted in increased DUI news coverage and that additional police officer hours for DUI enforcement, greater use of breathalyzer equipment, increased officer training and more checkpoints produced increased DUI enforcement. The combined effects of increased DUI news coverage and DUI enforcement yielded increased public perceived risk of arrest and subsequently less drinking and driving. Overall the evaluation found that alcohol-involved traffic crashes were reduced as a result of this component in the experimental communities as contrasted with the matched comparison communities.

A cognitive analysis of server intervention policies: perceptions of bar owners and servers.

OBJECTIVE: The present study examined the underlying psychological variables relevant to alcohol server intervention policies. The focus of the research was the theoretical examination of college bar owners' and servers' attitudes and beliefs about server intervention policies. METHOD: Owners (n = 185) and servers (n = 185) of college bars were asked about their attitudes and perceived cognitive outcomes regarding server intervention policies. RESULTS: Although the findings revealed no statistical differences between owners and servers on their attitudes toward the different server intervention policies, statistical differences were found between the different policies (p < .05). Favorable policies focused on providing services to customers, whereas unfavorable policies focused on limiting the sales of alcohol. Finally, structural equation modeling revealed perceived cognitive outcomes related to the attitudes toward different server intervention policies. CONCLUSIONS: According to the present study's theoretical orientation, the attitudes are likely to have a direct influence on the adoption of policies or, on the part of the server, compliance with the policies. These attitudes toward the policies were found to be a function of the perceived hassle of implementing the policies and how effective the policy was in preventing driving under the influence.

Are a blood alcohol concentration of 256mg/dl and minimal signs of impairment reliable indications of alcohol dependence?

This article describes a drunk-driving scenario where a woman was apprehended for driving under the influence (DUI) with a blood alcohol concentration (BAC) of 256mg/dl. The correctness of this result was vigorously challenged by a medical expert witness for the defence, who was actually a specialist in alcohol diseases. Despite reanalysis to confirm the BAC as well as a DNA profile to prove the identity of the blood specimen, the woman was acquitted of the charge of drunk driving by the lower court. However, she was subsequently found guilty in the High Court of Appeals with a unanimous decision and sentenced to four weeks imprisonment. This case report illustrates some of the problems surrounding the use of expert medical evidence by the defence to challenge the validity of the prosecution evidence based solely on a suspect's BAC. In situations such as these, an expert witness should be called by the prosecution to clarify and, if necessary, rebut medical and/or scientific opinions that might mislead the court and influence the outcome of the trial.

Driving over 65: proceed with caution.

The issue of driving in the elderly population will continue to be relevant for public discourse. Because the termination of driving may be seen as an end of independence, it is important to appreciate that it has both emotional and pragmatic consequence. Senescence includes a host of physiological changes that may influence one's driving ability. Yet, aging alone does not infer poor driving ability. Health care providers should encourage and support the development of accurate methods of evaluation for older drivers and discuss adaptive strategies with older drivers in an effort to maintain their independence while promoting public safety.

Top ten defence challenges among drinking drivers in Sweden.

This paper gives a review and opinion about defence challenges arising during the prosecution of drinking drivers in Sweden. The statutory limit of blood-alcohol concentration (BAC) is two-tiered; 0.2 mg/g (21 mg/100 ml) and 1.5 mg/g (159 mg/100 ml). In rank order of occurrence, the top ten defence challenges are shown in Table I. The hip-flask defence occurs in more than 90% of all challenges. Because the burden of proof in Swedish law rests on the prosecution, the charge of driving under the influence of alcohol is often dropped when alleged drinking after the offence is an issue.

Practice parameter: risk of driving and Alzheimer's disease (an evidence-based review) [RETIRED]: report of the quality standards subcommittee of the American Academy of Neurology.

Studies of automobile accident frequency among drivers with AD have yielded conflicting results about the risk of accidents. To develop a practice parameter regarding driving and AD the authors performed a systematic review of the literature. The authors identified well-designed, controlled studies of driving and AD using the National Library of Medicine's MEDLINE database. The authors also compared the relative rates of crashes and other performance measurements of driving ability in the populations studied. Driving was found to be mildly impaired in those drivers with probable AD at a severity of Clinical Dementia Rating (CDR) 0.5. This impairment was no greater than that tolerated in other segments of the driving population (e.g., drivers age 16 to 21 and those driving under the influence of alcohol at a blood alcohol concentration [BAC] < 0.08%). Drivers with AD at a severity of CDR 1 were found to pose a significant traffic safety problem both from crashes and from driving performance measurements.

Culpability and accountability of hospitalized injured alcohol-impaired drivers. A prospective study.

During the three-year period ending October 1982, driver records, crash reports, and blood alcohol concentrations were correlated for 56 alcohol-impaired drivers injured seriously enough to warrant hospital admission. Blood alcohol concentration levels exceeded 0.15 vol% in all patients. Despite a high level of suspicion of alcohol involvement and assessment of culpability by the law enforcement officer at the scene, there were no convictions for driving under the influence of alcohol (DUI) among this problem-drinker population. Injury seems to offer additional protection from enforcement of DUI statutes and, if the patient survives his injuries, allows the offender to resume driving without interdiction.

[Increased frequency of driving accidents in epilepsy].

INTRODUCTION: The influence of medical conditions on the ability to drive safely is a matter of concern to both physicians and society. Satisfactory answers to the many questions are not yet available, because of methodological difficulties, including the inability to collect sufficiently large and representative samples of drivers with specific diseases, and to acquire reliable accident data. For epilepsy, the conclusions of scientific reports vary from "there is little to worry about" to an increased relative risk of 1.9. As a consequence, attitudes and regulations vary greatly throughout the world. MATERIAL AND METHODS: A ten-year historical cohort register study of 159 patients with epilepsy and 559 controls individually matched for age, gender, place of residence, and exposure period. Recorded diagnoses of other relevant diseases led to exclusion. The outcome measure was treatment at the casualty department after an accident as a car driver. RESULTS: Ten patients and five controls had been treated at the casualty department, the rate ratio per 1,000 person-years with exposure being 7.01 (CI 2.18-26.13). DISCUSSION: This study showed that drivers with epilepsy seven times more often than healthy controls were treated at a casualty department after having a road traffic accident. In view of the small numbers of accidents and the surprising findings, the results must be interpreted cautiously. It is not advisable at this time to liberalize demands, but, on the other hand, drastic inferences regarding the patients' automobile driving should be avoided until the results have been further substantiated.

Comparison of alcohol consumption patterns and social problems between women and men drink-drivers.

OBJECTIVE: To compare the sociodemographic characteristics, patterns of alcohol consumption and driving histories of women and men drink-drivers. DESIGN: Cross-sectional descriptive study. SETTING AND SUBJECTS: All 156 women who attended the Drink-Drive Program at St Vincent's Hospital, Melbourne, between January 1990 and December 1993, and an age-matched sample of 298 men attending in the same period. All had been disqualified from driving after a conviction for driving under the influence of alcohol. OUTCOME MEASURES: Self-reported weekly alcohol consumption and expenditure on alcohol at apprehension and during the program; blood alcohol level (BAL) at apprehension; demographic characteristics; number of previous drink-drive and other traffic convictions; and score on the Michigan Alcoholism Screening Test (MAST). RESULTS: Women had a higher educational level than men, and were more likely to be managers or professionals and to live in areas of high socioeconomic status. Women reported lower levels of weekly alcohol consumption at both apprehension (women: 15.2 standard drinks; men: 31.6 standard drinks) and during the program (women: 7.1 standard drinks; men: 12.0 standard drinks) but had similar BALs to men at apprehension (mean, 0.12% [26 mmol/L]). Sixty percent of women drank wine, or wine, beer and spirits, while 75% of men drank beer. Women had lower MAST scores than men (mean [standard deviation]: women, 5.8 [5.2]; men, 8.9 [8.2]). Women were less likely than men to have prior convictions for drink-driving or other traffic offences. CONCLUSION: Although women presented with similar blood alcohol levels to men, their drinking patterns and sociodemographic characteristics differ greatly. Health education for women drink-drivers needs to have a different strategy to that for men.

Role of cold receptors and menthol in thirst, the drive to breathe and arousal.

Menthol is widely used in candy, chewing gum, toothpastes, cigarettes and common cold medications. Menthol has been shown to stimulate cold receptors in the mouth and nose. The present paper puts forward the hypothesis that menthol, by its effects on oral and nasal cold receptors, may influence thirst, the drive to breathe, and arousal. The satisfying effects of menthol on thirst and breathing, together with an effect on arousal, may explain the popularity of menthol and account for the very large amount of menthol-containing products that are consumed each day.

Dose related risk of motor vehicle crashes after cannabis use.

The role of Delta(9)-tetrahydrocannabinol (THC) in driver impairment and motor vehicle crashes has traditionally been established in experimental and epidemiological studies. Experimental studies have repeatedly shown that THC impairs cognition, psychomotor function and actual driving performance in a dose related manner. The degree of performance impairment observed in experimental studies after doses up to 300 microg/kg THC were equivalent to the impairing effect of an alcohol dose producing a blood alcohol concentration (BAC) >/=0.05 g/dl, the legal limit for driving under the influence in most European countries. Higher doses of THC, i.e. >300 microg/kg THC have not been systematically studied but can be predicted to produce even larger impairment. Detrimental effects of THC were more prominent in certain driving tasks than others. Highly automated behaviors, such as road tracking control, were more affected by THC as compared to more complex driving tasks requiring conscious control. Epidemiological findings on the role of THC in vehicle crashes have sometimes contrasted findings from experimental research. Case-control studies generally confirmed experimental data, but culpability surveys showed little evidence that crashed drivers who only used cannabis are more likely to cause accidents than drug free drivers. However, most culpability surveys have established cannabis use among crashed drivers by determining the presence of an inactive metabolite of THC in blood or urine that can be detected for days after smoking and can only be taken as evidence for past use of cannabis. Surveys that established recent use of cannabis by directly measuring THC in blood showed that THC positives, particularly at higher doses, are about three to seven times more likely to be responsible for their crash as compared to drivers that had not used drugs or alcohol. Together these epidemiological data suggests that recent use of cannabis may increase crash risk, whereas past use of cannabis does not. Experimental and epidemiological research provided similar findings concerning the combined use of THC and alcohol in traffic. Combined use of THC and alcohol produced severe impairment of cognitive, psychomotor, and actual driving performance in experimental studies and sharply increased the crash risk in epidemiological analyses.

Self-reported visual problems of older drivers.

We conducted a survey in order to gain insights into the reasons older persons decide to give up driving. Our survey focused on vision. We probed the relationship between visual deficiencies and driving status by asking older people about the problems they encountered while performing routine visual tasks. The results showed that older persons who had recently given up driving reported more visual problems than did their driving counterparts. These problems related to difficulties in dynamic vision, visual processing speed, visual search, light sensitivity, and near vision. The results suggested that older persons are sensitive to their own visual deficits and that this awareness influences decisions about driving.

[Alcohol, pharmaceuticals, illicit drugs and driving].

A great number of clinical, epidemiological, pharmacological and toxicological data on the influence of psychotropics on driving are available. These psychotropics include psycholeptics like ethanol, opioids, psychoanaleptics like cocaine, amphetamines and congeners, psychodysleptics like cannabis, LSD and magic mushrooms. General epidemiology and specific epidemiology for Luxembourg will be outlined. Practical aspects of roadside testing, forensic aspects as well as the place of hair testing in drugs and road safety issues will be discussed.

Are problem drinkers dangerous drivers? An investigation of arrest for drinking and driving, serum gamma glutamyltranspeptidase activities, blood alcohol concentrations, and road traffic accidents: the Tayside Safe Driving Project.

Serum gamma glutamyltranspeptidase activity was measured in 440 drivers at the time of arrest for driving under the influence of alcohol. The results were compared with information gathered by the arresting police officer. One third of drivers over the age of 30 had abnormal gamma glutamyltranspeptidase activities at the time of arrest. Among drivers who required a driving license for their work, and older drivers, a disproportionately high number had raised gamma glutamyltranspeptidase activities indicating problem drinking. In drivers over the age of 30 a strong association was found between gamma glutamyltranspeptidase activities and road traffic accidents but not alcohol concentrations or previous convictions. These findings argue against the Department of Transport's criteria for high risk offenders and indicate a clear need for new measures against problem drinkers among drinking and driving offenders.

License plate confiscation for persistent alcohol impaired drivers.

Minnesota cancels the registrations and confiscates the license plates of vehicles driven by repeat drinking drivers in a procedure which prior research has demonstrated to be effective in reducing subsequent recidivism. The research reported here concerns the problems experienced in the functioning of this law. Samples of officials and repeat driving under the influence (DUI) offenders were interviewed in Minnesota and in the neighboring state of Iowa, chosen for comparison because its laws also provide for plate confiscation, but using a judicial rather than an administrative procedure. In addition, representative samples of the driving and vehicle registration records of convicted drunk drivers and of routine traffic offenders were analyzed. The research found that evasion of plate impoundment orders by drivers, though apparently easy to accomplish, appeared to be rare. However, the orders were themselves not issued in a large proportion of cases where they were prescribed by statute, potentially weakening the effectiveness of the law. The reasons, with possible countermeasures, are explored in this report.
