SUMMARY

The discussion centers on an individual charged with DUI seeking statistical proof to demonstrate a blood alcohol concentration (BAC) under 0.08 at the time of driving. The individual recorded a portable breath test result of 0.219 and subsequent Datamaster tests of 0.217 and 0.203, taken 31 and 44 minutes after the stop, respectively. The user aims to leverage statistical methods learned in college to argue their case, but the conversation shifts towards the dangers of drunk driving and the importance of legal counsel.

PREREQUISITES
  • Understanding of BAC measurement and implications of DUI laws
  • Basic knowledge of statistical concepts, including standard deviation and sample size calculations
  • Familiarity with breathalyzer technology, specifically the Datamaster model
  • Awareness of the legal process surrounding DUI charges
NEXT STEPS
  • Research statistical methods for estimating BAC over time, including regression analysis
  • Learn about the accuracy and calibration of breathalyzer devices, particularly the Datamaster
  • Explore legal strategies for DUI defense, focusing on self-representation
  • Investigate the impact of time on BAC reduction and related physiological factors
USEFUL FOR

This discussion is beneficial for individuals facing DUI charges, legal professionals interested in DUI defense strategies, and anyone studying the statistical analysis of alcohol impairment.

Was charged with DUI and am choosing to go to trial and represent myself. I want a statistical proof that I was under 0.08. I'll send this proof to a university professor to verify its validity.

Portable breath test (road side): 0.219
Datamaster breath test (police station): 0.217, 0.203

The first test was 31 minutes after being pulled over and the other two were 44 minutes after that. Armed with this info, I would like to statistically prove that I was under 0.08 when driving (i.e. 31 minutes before portable breath test).

I used to take Statistics in college, so I remember there's stuff like sqrt(N) and so forth. Can someone help me out here?

You seem to be interested in statistics, so how about these?

31% of traffic related deaths in the United States are due to drunk driving.
In 2011, over 1,000 children (<14) were killed due to drunk driving.
Drunk driving costs the US some $50 billion/year. New plan, why don't you not drink and drive? Instead of trying to cheat the system, man up and move on. Learn your lesson and quit endangering the lives of others.

Sorry, but we can't help with legal matters. Find a lawyer and see what they have to say. Thread locked.
