Final answer:
At a BAC of 0.05%, side vision is typically decreased. Low levels of alcohol can impair driving-related tasks and side vision, and it is illegal to drive with a BAC of 0.08% or higher in most US states.
Step-by-step explanation:
At a Blood Alcohol Concentration (BAC) of 0.05%, side vision, also known as peripheral vision, is impaired. The consumption of alcohol can lead to a reduction in visual acuity, affecting tasks requiring skill and judgment, such as driving. It is illegal in most US states to drive with a BAC of 0.08% or higher due to these impairments. At lower levels, the impacts may be less severe but still significant, and 0.05% BAC is often associated with a decrease in side vision and reaction times. It's important to note that drinking and driving is dangerous and that even a small amount of alcohol can reduce driving performance.
