      <title>Acute and hang-over effects of alcohol on simulated driving performance</title>
      <link>https://trid.trb.org/View/1176789</link>
      <description><![CDATA[The aim was to study hang-over effects from alcohol in simulated driving. The driving task was to negotiate 20 km in as short time as possible.  The road had many curves, horizontal and vertical, with ice friction at irregular on at irregular intervals.  24 healthy volunteers, aged 22-46, with valid driving licenses, all screened as moderate drinkers, participated as subjects in a repeated measurements design.  In the acute intoxicated state (average BAC 150 mg%), driving performance was severely impaired.  Performance was also impaired, but to a much lesser degree, in the morning after the alcohol consumption when average BAC was just below 40 mg%.  Later during the day no significant differences were demonstrated. After another night's sleep, all effects were gone.  An issue raised in a previous study on hang-over effects, whether the subjects were treated exactly alike in the hang-over and the control conditions the night before testing (with the exception for the alcohol consumption in the first case), that is attended a party and stayed overnight at the research institute in both conditions, or whether they did so only in the hang-over condition, did not seem to matter for the estimated hang-over effect.]]></description>

      <title>HANGOVER EFFECTS OF ALCOHOL ON DRIVER PERFORMANCE IN SIMULATED DRIVING</title>
      <link>https://trid.trb.org/View/298784</link>
      <description><![CDATA[Possible hang-over effects of alcohol on driver performance in a sophisticated driving simulator were investigated.  The driving task was demanding and rquired the Ss to drive a 20 km test distance in as short time as possible.  The road had horizontal as well as vertical curves.  The Ss participated in drinking parties which preceded each hang-over condition. Each S chose to drink one of four alternative beverages: whisky, vodka diluted in orange juice, wine-red or white, or export beer.  Free and ample supply of food and beverages was provided.  It appeared that performance was lowered in the morning when average BAC was just below 0.04%.  Each S made another 3 test runs during the day, 2.5 hours apart. No perfomrmance decrement was found at these later occasions, however.  After another night's sleep all effects were gone.]]></description>

      <title>HANG-OVER EFFECTS OF ALCOHOL ON DRIVER PERFORMANCE</title>
      <link>https://trid.trb.org/View/182785</link>
      <description><![CDATA[The aim was to study hang-over effects of alcohol on driver performance when all alcohol has been metabolized. The driving task was an avoidance maneuvre putting high demands on attention, reaction time, precision and coordination. Each of the 22 subjects participated in an arranged drinking party. The day after when their BAC was down to zero the first hang-over driving tests were carried out. Three hours later the same tests were repeated. It was found that driving performance was impaired in both hang-over conditions when compared to the subjects' normal performance. The subjects acted as their own controls in rotated order of conditions. No relationship was found between impairment and subjective well-being in the hang-over condition. When the subjects were awakened they were asked to estimate their BAC and time needed to become completely sober. Some gross under- as well as overestimations were made.]]></description>

      <title>HANG-OVER EFFECTS OF ALCOHOL ON DRIVER PERFORMANCE</title>
      <link>https://trid.trb.org/View/180294</link>
      <description><![CDATA[The purpose of the investigation was to study possible hang-over effects of alcohol on driver performance when all alcohol had been metabolized.  The car was driven on a closed-course in a cone setting.  Upon a signal, the driver had to try to avoid the cones. The initial speed was 50 km/h.  The driving task puts heavy demands on attention, reaction time, precision and coordination.  The number of cones run down was used as a measure of driving performance. Five subjects participated in each drinking party, during which free and ample supply of food and alcoholic beverages were provided.  After eight hours sleep, the subjects were awakened and as soon as their blood alcohol concentration (BAC) was down to zero, the first hang-over measurements were carried out. Three hours later the same driving tests were repeated.  The results showed that all 22 subjects hit more cones in the hang-over conditions as compared to their own results in the normal condition.  The average performance decrement was approximately 20%.  The results can be summarized in four points: (1) impairment of driving performance is evident well into the next day even though all alcohol is metabolized (2) the impairment persists for at least 3 hours after all alcohol has disappeared (3) the impairment shows little correlation with subjective hang-over (4) it is difficult to estimate your own BAC the next day and to calculate the time needed to become completely sober.
