“…Sources of variability in alcohol-related impairment can be attributed to experimental design, for example, dosing regimen, task complexity, and practice effects. As noted by Flanagan et al (80), the drivers in their study were not permitted to become too familiar with the course prior to testing and therefore would be expected to improve their performance on their second run, which represents a confound in differentiating between continued learning and the effects of alcohol on driving.…”

The operation of a motor vehicle requires the integrity of sensory, motor, and intellectual faculties. Impairment of these faculties following the consumption of alcohol has been studied extensively through laboratory, closed-course and on-road driving, and epidemiological studies. The scientific literature was reviewed critically, with a focus on low-to-moderate blood alcohol concentrations (BAC ≤ 0.100%), to identify the most reliable determinants of alcohol-impaired driving. Variables such as age, gender, driving skill, and tolerance were shown to have limited impact on impairment. It was concluded the most relevant variables are BAC and complexity of the driving task. The scientific literature provides a high degree of confidence to support the conclusion that a BAC of 0.050% impairs faculties required in the operation of a motor vehicle. Whether impairment is apparent depends upon the complexity of the driving task, which applies to both study design and actual driving.

“…The number of pylons struck and the stopping distances were greater in the 0442% BAC trials than in the 0-00% BAC trials. Further, in a recent closed-course study, Flanagan et al (1983) compared the hazard avoidance performance of 46 drivers before and after consuming 0.946 to 1 183 litres of beer (0.03 to 0.06% BAC). Driver performance after alcohol consumption was characterized by an increased number of strikes on road hazards and excessive speed.…”

The effect of alcohol consumption on driving performance was examined in two studies. In the first, six subjects drove for two hours over a closed-loop, two-lane course. In the second, 12 subjects drove for two hours in a driving simulator. In both studies, target blood alcohol concentrations (BAC) were 0.00%, 0.07%, or 0-12%. Multiple measures of vehicle control, tracking and information processing were recorded. In general, the standard deviations of these measures increased as BAC increased. Differences in the results between the two studies were related to differences in facilities (i.e. closed course vs. driving simdator).

“…Judgement may also be affected with people overestimating their abilities (Flanagan et al 1983; Tiplady et al 2004), including being able to deal with a potentially risky situation or acting on immediate short-term consequences rather than longer-term consequences (Farquhar et al 2002). Specific to driving, alcohol may cause a ‘risky shift’, resulting in hitting the test bollards and failing the gap acceptance test (Alford and Starmer 1990, personal communication; Betts et al 1984).…”

The effects of energy drink in combination with alcohol on performance and subjective awareness

RationaleThis study investigated the coadministration of an energy drink with alcohol to study the effects on subjective intoxication and objective performance.ObjectivesThis study aims to evaluate the objective and subjective effects of alcohol versus placebo at two alcohol doses, alone and in combination with an energy drink, in a balanced order, placebo-controlled, double-blind design.MethodsTwo groups of ten healthy volunteers, mean (SD) age of 24 (6.5), participated in the study. One group consumed energy drink containing 80 mg of caffeine and the other consumed a placebo drink, with both receiving two alcohol doses (0.046 and 0.087% breathalyser alcohol concentration). Tests included breath alcohol assessment, objective measures of performance (reaction time, word memory and Stroop task) and subjective visual analogue mood scales.ResultsParticipants showed significantly impaired reaction time and memory after alcohol compared to the no alcohol condition and had poorer memory after the higher alcohol dose. Stroop performance was improved with the energy drink plus alcohol combination compared to the placebo drink plus alcohol combination. Participants felt significant subjective dose-related impairment after alcohol compared to no alcohol. Neither breath alcohol concentration nor the subjective measures showed a significant difference between the energy drink and the placebo energy drink when combined with alcohol.ConclusionsSubjective effects reflected awareness of alcohol intoxication and sensitivity to increasing alcohol dose. There were no overall significant group differences for subjective measures between energy drink and placebo groups in the presence of alcohol and no evidence that the energy drink masked the subjective effects of alcohol at either dose.
