“…Even with this limitation, on‐road driving studies may more realistically reflect the increased complexity of actual traffic situations as demonstrated in the results reported by Parks et al. , who observed significantly increased SDLP in 60 subjects taking part in an on‐road driving study where BACs averaged 0.042% before driving and dropped to an average of 0.031% after driving.…”

“…(18). Parks et al (68) reported no effect of gender on actual driving performance or laboratory tests of divided attention, and Drew et al (31) reported that the effects of alcohol in 40 volunteers tested on a driving simulator were not affected by differences in age, gender, previous driving experience, or drinking habits. Because the subjects in this study varied widely in their initial driving skill, a within-subject design was used to control individual differences in driving skill (31).…”

“…Some researchers have controlled this variable by ensuring that study participants are in the postabsorptive phase at the time of testing (4,49,50,55,62). Parks et al (68) documented significant increases in the time required to respond to a peripheral stimulus during a laboratory-based divided attention task and similarly observed significant increases in SDLP in an on-road driving study comprising 60 subjects despite a decline in the mean BAC from 0.042% to 0.031% throughout the exercise, that is, in the presence of acute tolerance. In such experiments, an observed decrease in ability to perform a task will likely underestimate alcohol-related impairment when the BAC is rising.…”

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 effects of low doses of alcohol on cognitive performance which have been found include significant impairments of divided attention, and immediate and delayed free recall; however, no impairment of word recognition was observed despite delays in reaction time to the words (Parks et al 2002). Other cognitive effects of alcohol include impaired response inhibition Vogel-Sprott 1999, 2000), restricted focus of attention (Steele and Josephs 1990) and risk perception (Frick et al 2000).…”

Using the lane change task (LCt) a comparison of driving performance was made between normal (baseline) driving, driving whilst using an in-vehicle information system (IVIS) and driving while intoxicated at the UK blood alcohol level (80 mg per 100 ml). the results provided clear evidence for impaired performance of the LCt when performing an IVIS task in comparison to both baseline (LCt alone) and alcohol conditions. However, the LCt was found to be insensitive to the effects of alcohol in the absence of a secondary task. It is concluded that LCt performance can be impaired more when undertaking certain IVIS tasks than by having a blood alcohol level at the UK legal limit but the LCt requires further development before it can be used as a convincing proxy for the driving task. a s h g a t e. c o m a s h g a t e. c o m a s h g a t e. c o m a s h g a t e. c o m a s h g a t e. c o m a s h g a t e. c o m a s h g a t e. c o m a s h g a t e. c o m a s h g a t e. c o m © Copyrighted Material © Copyrighted Material Driver Distraction and Inattention 254 a s h g a t e. c o m a s h g a t e. c o m a s h g a t e. c o m a s h g a t e. c o m a s h g a t e. c o m a s h g a t e. c o m a s h g a t e. c o m a s h g a t e. c o m a s h g a t e. c o m © Copyrighted Material © Copyrighted Material Driver Distraction and Inattention 256 a s h g a t e. c o m a s h g a t e. c o m a s h g a t e. c o m a s h g a t e. c o m a s h g a t e. c o m a s h g a t e. c o m a s h g a t e. c o m a s h g a t e. c o m a s h g a t e. c o m

“…In case of multiple tasks, people under the influence of alcohol tend to favor just one task, resulting in a strong decrease in performance for the secondary task from 0.2 g/l; some cognitive capacities (memory, response time) are affected from near 0.5 g/l (Parks et al 2002) and can show a dose effect (Bisby et al 2009). Vigilance level and eye tracking are also affected at very low doses of alcohol (Moskowitz et al 1985) and motor functions appear to be more affected than cognitive functions (Koelega 1995).…”

Rationale: Alcohol is the most frequently detected substance in fatal automobile crashes, but its precise mode of action is not always clear.Objective: The present study was designed to establish the influence of blood alcohol concentration as a function of the complexity of the scenarios. Road scenarios implying automatic or controlled driving performances were manipulated in order to identify which behavioral parameters were deteriorated.Method: A single blind counterbalanced experiment was conducted on a driving simulator. Conclusion:Performance decrement was greater with driving scenarios involving automated processes than with scenarios involving controlled processes.
