Which statement is correct regarding impairment while driving?

The statement regarding a driver being able to be convicted under a blood alcohol level (BAL) of .08 if proven impaired is correct because impairment can be determined through various means beyond just a specific numerical threshold of BAL. While .08 is a common legal limit for driving under the influence, a driver may still exhibit impaired abilities even with a BAL below this level. Law enforcement and the legal system acknowledge that factors like physical coordination, cognitive function, and overall behavior can indicate impairment. Therefore, evidence of impairment — whether through field sobriety tests, erratic driving behavior, or witness accounts — is sufficient for a conviction even if the driver's BAL is under .08.

This approach allows for a more comprehensive understanding of what constitutes safe driving, recognizing that impairment can happen at lower levels of alcohol consumption.
