Final answer:
In New Jersey, the legal BAC limit for drivers under 21 is 0.01%. The legal limit for those over 21 is 0.08%, following the National Minimum Drinking Age Act of 1984. BAC can be measured with a Breathalyzer, with blood alcohol levels above 0.08% indicating legal impairment in adults.
Step-by-step explanation:
In New Jersey, it is illegal for individuals under the age of 21 to drive with a blood alcohol concentration (BAC) above 0.01%. The statewide standard BAC limit for drivers over the age of 21 is 0.08%, in accordance with the National Minimum Drinking Age Act of 1984, which mandates states to set the minimum legal drinking age to 21.
However, for younger individuals, who are not legally allowed to consume alcohol, the tolerance is set much lower to discourage any underage drinking and driving.
The BAC can be measured using devices such as a Breathalyzer, which estimates the alcohol concentration by analyzing a breath sample. Blood alcohol levels are an indicator of intoxication, with levels above 0.08% indicating legal impairment in adults.
The human body metabolizes alcohol at a rate of approximately 15 mg/dL per hour, which can vary based on a number of factors including body weight, gender, and individual metabolism.
