Final answer:
If found with a BAC of 0.02 at a roadside rest area, the consequences depend on age, driver type, and jurisdiction. Adults over 21 may face no penalty, but underage drivers could be fined or warned due to zero-tolerance laws. Commercial drivers may also have stricter BAC limits.
Step-by-step explanation:
If you are stopped at a roadside rest area and found to have a BAC of 0.02, it depends on the context such as your age and the jurisdiction you are in. For most adult drivers in the United States, the legal limit of Blood Alcohol Concentration (BAC) is 0.08%. However, for drivers under the age of 21, any detectable amount of alcohol could result in penalties due to zero-tolerance laws. In some cases, commercial drivers might also face stricter limits.
While a BAC of 0.02 is below the legal limit of 0.08% for adults over 21, if you are under 21, you may still face consequences such as fines or license suspension. If the situation is aggravated by other factors, like erratic driving, the officer might have grounds for further action regardless of BAC.
Due to these variations, the most suitable options are either (2) You will be fined or (4) You will be given a warning, depending on the specific circumstances and local laws regarding underage drinking and driving or commercial driving standards.
