True or False: It is illegal to drive with a blood alcohol concentration (BAC) over 0.08%.

The statement is true because in most states across the United States, it is indeed illegal to operate a motor vehicle with a blood alcohol concentration (BAC) of 0.08% or higher for drivers aged 21 and older. This legal limit is established to promote safe driving and reduce the incidence of alcohol-related accidents.

Driving with a BAC over the legal limit impairs a person's ability to operate a vehicle safely, leading to impaired judgment, slow reaction times, and diminished coordination. Law enforcement agencies actively enforce this law through sobriety checkpoints and roadside assessments, ensuring that those who drive under the influence face legal consequences.

While special rules apply to underage drivers, as they are typically not allowed to have any measurable amount of alcohol in their system, the overarching law regarding BAC limits is firmly established at 0.08% for adults.
