A recent study that looked at 15 years of U.S. crash data found that about 15% of alcohol-related motor vehicle fatalities involve drivers with a BAC below 0.08%. In more than half of incidents where this occurred, the drinking driver was not the one who died (8). When asked whether they believed their BAC at the time of their most recent drinking–driving trip was above or below the legal limit, about 10 percent of all age drivers believed they were above the legal limit. Forty-four percent of drivers ages 16 to 20 believed they were above the legal limit. This suggests that more than half (56 percent) of the 16- to 20-year-old drinking drivers questioned were not aware that driving after any drinking is illegal for them. However, fatally injured drivers with BACs of 0.15 percent and higher were twice as likely to drive after drinking at least weekly (40 percent vs. 20 percent), and three times more likely to be rated as a problem drinker (31 percent vs. 10 percent).
Save lives: a road safety technical package
- Over 10,000 people die each year in the U.S. from alcohol-related car crashes.
- A systematic review of randomized controlled trials to reduce alcohol dependence and abuse among the general population (Dinh-Zarr et al. 1999) has found beneficial effects in reducing not only alcohol consumption but also drinking and driving offenses.
- Adding alcohol into the mix and lowering their inhibitions further often results in incredibly reckless driving.
- A possible explanation is that as residents of suburban areas are more dependent on automobiles to travel, more driving is necessary for suburban residents.
To reduce alcohol-related fatal crashes among youth, all states have adopted a minimum legal drinking age of 21. NHTSA estimates that minimum-drinking-age laws have saved 31,959 lives from 1975 to 2017. Stakeholder marketing also encompasses corporate social responsibility (CSR) activities such as efforts to consequences of driving drunk include: prevent alcohol-impaired driving. However, global analyses of alcohol industry CSR activities have consistently found that the alcohol industry pursues and supports the least effective strategies and actively opposes the most effective (Babor et al., 2015, 2018; Esser et al., 2016; Pantani et al., 2017).
Standard Drinks
In addition, the practice of mixing alcohol and caffeine, while effectively banned at the point of production at least for malt beverages (Babor et al., 2017), continues to be common, particularly among young binge drinkers (CDC, 2017a). Findings from a review of randomized controlled studies suggest that although energy drink consumption may deter small declines in cognitive function that result from alcohol consumption, such counteracting effects are not observed when driving (Babor et al., 2018; Lalanne et al., 2017). In addition, evidence suggests that consumption of drinks combining alcohol and energy drinks hinders a person’s ability to estimate their level of impairment (Forward et al., 2017). Drivers who underestimate their BAC are more willing to drive while above the limit set by state law compared to drivers who more correctly assess their BAC, and drivers who incorrectly estimate low BAC levels exhibit riskier driving (Laude and Fillmore, 2016). Furthermore, some impaired drivers exhibit riskier behaviors even while their psychomotor skills are not demonstrably compromised. Conversely, other drivers’ risky behavior may not change but their psychomotor skills could be significantly impaired (Laude and Fillmore, 2016).
Effect of different breath alcohol concentrations on driving performance in horizontal curves
It’s no secret that alcohol consumption impairs driving skills and judgement. However, the effects of alcohol on an individual can vary depending on several factors. In this subsection, we will explore some of the factors that can influence the effects of alcohol on driving skills and judgement.
Age of Drinking Onset and Alcohol-Related Crash Involvement
Although total alcohol-related traffic fatalities have decreased, the degree of decline varies when BAC is considered. The numbers of traffic deaths involving people with BACs up to 0.08 percent had the smallest proportional decline (19 percent) from 1982 to 2002 (see figure 2). Traffic deaths among people with BACs of 0.08 percent and higher declined 35 percent, and those involving people with BACs of 0.15 percent and higher declined 37 percent. Consistent with the roadside survey results, traffic deaths involving alcohol declined markedly from the early 1980s to 1996, but during the last 6 years the downward progress has abated and alcohol-related traffic deaths have actually increased somewhat (NHTSA 2003a). The proportion of alcohol to blood in the body is referred to as the blood alcohol concentration (BAC). A person’s BAC is determined by his or her drinking rate and by the body’s absorption, distribution, and metabolism of the alcohol.
- The average distance of the average drinking–driving trip was greater than 16.7 miles for males, compared with 8.5 miles for females.
- Despite this progress, alcohol-impaired driving persists today, and alcohol-impaired driving fatalities have constituted almost 31 percent of overall motor vehicle crash fatalities in the last 10 years from 2006 to 2016 (Michael, 2017; NCSA, 2016a, 2017a).
- Despite standard drink sizes for beer, wine, and distilled spirits (see Chapter 1 for more information on standard drinks), it is often difficult for individuals to determine the amount of alcohol they have consumed because of variations in alcohol content per drink.
- It is also worth noting that the blood alcohol concentrations analyzed here are all below the legal limit of 0.08%.
- The unique challenges and characteristics of the rural environment will be discussed as important considerations in the design and implementation of interventions throughout the report.
- Often called “drunk driving” interchangeably, it refers to operating any vehicle (including bicycles, motorcycles, golf carts, etc.) while impaired.
- Data from the 1975–2016 Monitoring the Future survey suggest that 32 percent of college students binge drink (Schulenberg et al., 2017).2 Similarly, a review of studies on drinking among college students found a consistent national rate of binge drinking of about 40 percent (Wechsler and Nelson, 2008).
- It also affects their perception, making it difficult to assess distance, speed, and potential hazards.
- Traffic deaths among elderly people and children are less likely to be alcohol related than those among young and middle-aged adults.
