Under what conditions is a person deemed unfit to drive?
If their BAC exceeds 0.08% only
If they feel sleepy or tired
If their BAC is 0.05% or more, or their ability is impaired
If they have consumed two or more drinks
The correct answer is: If their BAC is 0.05% or more, or their ability is impaired
A person is deemed unfit to drive when their Blood Alcohol Concentration (BAC) is 0.05% or higher, or if their ability to operate a vehicle is impaired by other factors. This is based on the understanding that any amount of alcohol can affect a person's ability to drive safely. At a BAC of 0.05% or above, drivers are considered at risk, and their judgment, coordination, reaction times, and overall driving abilities can be compromised. This standard exists to promote road safety and reduce the likelihood of accidents related to impaired driving. In addition, impairment can occur due to various factors such as fatigue, medications, or distractions, making it crucial to assess one's capability to drive more holistically rather than relying solely on BAC measurements. This comprehensive approach underscores the critical importance of ensuring that individuals are not only within the legal limits but also fully capable of driving safely.
