Safer vehicle design and advancements in medical technology would explain that partially. You cant just look at deaths to determine if the DUI rate has gone up or down. You discount two major components toward the point youve attempted to make. DUI incidents without fatality, DUI incidents without a crash and finally DUI drivers not caught by law enforcement.<quoted text>The plain fact of the matter is that the percentage of traffic deaths where alcohol was a factor has declined. Try to explain that one away.
You claim the tougher laws have been effective. With 1.4 million arrests in 2010 that claim doesnt stand up.
Traffic deaths are on the rise. http://usnews.nbcnews.com/_news/2012/12/21/16...
Today alcohol is a factor in 37% of traffic fatalities of people 16-20. People that shouldnt be drinking at all under the law. This link indicates a reduction from the mid 70s. A factor you must consider when viewing the reduction is during the 1970s the legal drinking age was 18. The link does attribute the majority of the reduction to that factor. http://report.nih.gov/nihfactsheets/ViewFactS...
Compare alcohol involvement in fatal crashes in 1999 and 2009 http://www.census.gov/compendia/statab/cats/t... See document 1113 Alcohol Involvement for drivers in fatal crashes.
In 1999 the percentage was 20.3, in 2009 the percentage *increased* to 22.3.
Once again, DUI laws havent been effective. The 1.4 million arrests in 2010 is a clear indicator of that.
