The Harger Drunkometer was introduced in 1938 to help convict drunk drivers. 

Laws passed in some states define a drunk driver as one who drives with a blood alcohol level of 0.10% by mass or higher. The level of alcohol can be determined by titrating blood plasma with potassium dichromate according to the unbalanced equation... 

Bottom line on chemical weapons (it s the same if they use industrial chemical spills) they are intended to make you panic, to terrorize you, to herd you like sheep to the wolves. If there is an attack, leave the area and go upwind, or to the sides of the wind stream. They have to get the stuff to you, and on you. You re more likely to be hurt by a drunk driver on any given day than be hurt by one of these attacks. Our odds get better if you leave the area. Soap, water, time, and fresh air really deal this stuff a knock-out punch. Don t let fear of an isolated attack rule your life. The odds are really on your side... 

This decision meant that involuntary alcohol blood tests (and by extension, blood or other tests for drugs) were not unconstimtional in themselves. Roadside and other testing of suspected drunk drivers would later become routine. 

When suspected drunk drivers are tested with a Breathalyzer, the alcohol (ethanol) in the exhaled breath is oxidized to acetic acid with an acidic solution of potassium dichromate ... 

The authors conclude that drug use among DWI offenders may be much more widespread than is indicated by self-report. Drunk drivers and drugged drivers also reported significant differences in attitudes about driving under the influence of alcohol and other drugs. 

Drunk drivers are as dangerous to their passengers and other people on the road as they are to themselves. You have a choice... 

There has been considerable discussion in the world s medical literature and at medical conferences as to whether physicians should actually advocate initiation of alcohol consumption for patients who currently do not drink. Certainly, there is unequivocal proof of the cardiovascular benefits, but there is also unequivocal proof of the potential downside of drinking, both for the individual and for society as a whole. The horrors of deaths to drunk drivers and their victims come vividly and dramatically to mind, as does the sociological impact of alcoholism on the individual and his or her family. 

Our state should double the existing fines for first-offense drunk drivers. Such a move would lower the number of accidents, cut the costs of insurance, and increase the state revenues for highway maintenance. 

Destructive worry can lead to compulsive overparenting where parents drive themselves and their only child crazy with excessive needs for control. Parents can chain worry "If you flunk this class then maybe you ll flunk others, then maybe you ll drop out of school, and then maybe you ll end up living on the street " Parents can ask crazy questions (questions for which there are no answers) "How do you know for sure you won t get hit by a drunk driver and get killed " Parents can obsessively control "You re not...

Every year in the United States about 25,000 people are killed and 500,000 more are injured as a result of drunk driving. In spite of efforts to educate the public about the dangers of driving while intoxicated and stiffer penalties for drunk driving offenses, law enforcement agencies still have to devote a great deal of work to removing drunk drivers from America s roads. 

If this seems like an onerous burden on businesses that serve alcohol, you probably would not feel that way if someone you loved was killed by a drunk driver leaving a bar. Theoretically, it is the drinker who should be responsible enough to arrange for a safe way to get home if he or she intends to drink. However, alcohol impairs judgment. So drinkers cannot be relied upon to make good decisions. Therefore, the establishment that is making a profit on excessive alcohol use will have to be inconvenienced to reduce the harm that drunk drivers cause. 

The above Chemistry in Action essay describes how law enforcement makes use of a redox reaction to apprehend drunk drivers.

The amount of electrical current produced depends on the amount of alcohol in the breath. A higher current reveals a higher blood alcohol level. When calibrated correctly, the fuel-cell breathalyzer can precisely measure the blood alcohol level of a suspected drunk driver. 

Many police departments use breath tests to check for drunk drivers. What would be the approximate partial pressure of ethanol in expired breath if the blood alcohol content is approximately 0.06 mole % (that is, Xe,hanoi = 0.0006) The equilibrium vapor pressure of C2H5OH at 37°C is 115.5 torr. Use your answer to comment on the necessary sensitivity of the test.

When alcohol is present in the blood, it evaporates throngh the lungs. Thns, the percentage of alcohol in the lungs can be nsed to calculate the blood alcohol concentration (BAC). Several devices are used to measure the BAC. When a Breathalyzer is used, a suspected drunk driver exhales through a mouthpiece into a solution containing... 

When a suspected drunk driver blows 188 mL of his breath through the fuel-ceU breathalyzer described in Section 18.7, the breathalyzer produces an average of 324 mA of current for 10 s. Assuming a pressure of 1.0 atm and a temperature of 25 °C, what percent (by volume) of the driver s breath is ethanol ...
