  • Commercial motor vehicle operators while driving a commercial vehicle0.04% (Statutory limit for commercial vehicle operation)
  • Standard adult drivers aged 21 or older operating a personal passenger car0.08% (Statutory per se limit for adult non-commercial drivers)

Cevap

Under traffic safety laws, drivers under 21 correspond to the 0.01% - 0.02% Zero Tolerance threshold, commercial motor vehicle operators correspond to the 0.04% limit, and standard adult non-commercial drivers correspond to the 0.08% limit.
Each driver category maps precisely to its legal statutory limit: Zero Tolerance (0.01%–0.02%) applies to underage drivers, the commercial vehicle threshold is 0.04%, and the general adult non-commercial driver limit is 0.08%.

Commercial vehicle drivers have a stricter limit of 0.04% BAC.
Safety regulations lower the allowable threshold for heavy/commercial motor vehicles.
