Nevada Class C Driver's Practice Test 2025 – 400 Free Practice Questions to Pass the Exam

The legal blood alcohol concentration (BAC) limit for drivers over 21 in Nevada is 0.08%. This means that if a driver has a BAC of 0.08% or higher, they are considered legally impaired and can be charged with DUI (Driving Under the Influence). This standard aligns with regulations in many states across the U.S., reflecting a commitment to reducing alcohol-related accidents and promoting safe driving practices.

The other listed BAC levels are incorrect for this specific context. A BAC of 0.05% might be applicable for some specific categories of drivers, such as commercial vehicle operators, but it does not apply to the general public over the age of 21. Similarly, 0.10% and 0.04% are above and below the legal limit for regular drivers, respectively, and do not reflect the current legal standard in Nevada. Understanding these limits is crucial for ensuring safe driving and compliance with state laws.
