Final answer:
The Nebraska BAC limit for minor drivers under 21 is .02, which is part of the effort to discourage underage drinking and driving, aligning with zero-tolerance policies influenced by the National Minimum Drinking Age Act of 1984.
Step-by-step explanation:
The Nebraska blood alcohol concentration (BAC) limit for minor drivers under age 21 is a) .02. This limit is much lower than the standard BAC limit of .08 for drivers 21 and older. The lower limit is due to the National Minimum Drinking Age Act of 1984, which requires states to have a minimum drinking age of 21, and many states, including Nebraska, have implemented a zero-tolerance law for minors to discourage driving after any alcohol consumption. Screening for alcohol intoxication often involves the use of a breathalyzer, a device that measures the ethanol concentration in a person's breath, reflecting their BAC level. The legal consequences for violating BAC limits can include significant fines, loss of driving privileges, and in some cases, imprisonment.
