Final answer:
The percentage of all auto fatalities that were alcohol-related has decreased in the past 30 years due to campaigns, laws, enforcement, and technology. Data from sources like the NHTSA confirms this downward trend in alcohol-impaired driving fatalities.
Step-by-step explanation:
In the past 30 years, the percent of all auto fatalities that were alcohol-related has decreased. Efforts such as public awareness campaigns, stricter laws, and better enforcement have collectively contributed to this reduction. Moreover, technological advancements such as ignition interlock devices have also helped prevent drink driving.
Comparing data from different years, there's a noticeable trend reassuring the commitment to reducing alcohol-related auto fatalities. For example, the National Highway Traffic Safety Administration (NHTSA) reports that alcohol-impaired driving fatalities have decreased by 33% from 1982 to 2015.
However, while the percentage has decreased over time, alcohol-related crashes still remain a significant concern for road safety today, and continuous efforts are needed to further reduce these numbers.
