Difficulty: EasyBlood Alcohol Concentration (BAC) Limits and Thresholds

Match each driver category under standard driving safety regulations with its statutory legal Blood Alcohol Concentration (BAC) limit.

  • Adult non-commercial driver (aged 21 or older)0.08%0.08\% BAC
  • Commercial motor vehicle operator0.04%0.04\% BAC
  • Underage driver (under 21 years of age)0.01%0.01\% to 0.02%0.02\% BAC (Zero Tolerance)

Recognize that legal limits vary by driver age and vehicle classification.
Safety regulations mandate stricter standards for commercial drivers and underage drivers.
2
Match each driver classification to its corresponding statutory BAC percentage.
Standard adult drivers pair with 0.08%0.08\%, commercial operators pair with 0.04%0.04\%, and minor drivers pair with 0.01%0.01\%-0.02%0.02\% Zero Tolerance thresholds.
This correctly aligns each group with their exact statutory limit.
