Final answer:
A driver's license can be suspended for a BAC of 0.08 or over. The Breathalyzer is used to measure BAC, and various factors influence the effects of alcohol on an individual. The legal limit for intoxication is a universally applied standard, despite individual differences in alcohol metabolism and tolerance.
Step-by-step explanation:
A driver's license suspension under the Highway Traffic Act (HTA) for a Blood Alcohol Concentration (BAC) can occur when a driver has a BAC of 0.08 or over. In most countries, including almost all US states, a BAC of 0.08% by volume is legally considered to be the threshold for being dru_nk. Detection of BAC levels is commonly done using devices like the Breathalyzer, which measures the ethanol concentration in a person's breath and is directly proportional to their BAC.
The immediate effects of alcohol, such as poor judgment and decreased motor skills, can differ from person to person depending on various factors such as age, sex, pre-existing health conditions, and the amount of alcohol consumed. The National Minimum Drinking Age Act of 1984 is a significant legislation related to alcohol consumption, requiring states to raise the minimum drinking age to twenty-one or risk losing federal highway funds.
It's important to understand that the metabolism of alcohol by the liver is the only effective way to avoid alcohol toxicity. Coffee or a cold shower will not speed up this process. After consumption ends, a legally intoxicated person will need at least five hours to achieve sobriety, taking into account their liver's metabolism and alcohol excretion rates.
