What BAC range applies to Commercial Vehicle 1 general operation?

• A. 0.04-0.06
• B. 0.02-0.04
• C. 0.06-0.08
• D. 0.08-0.10

Answer: (A)

Commercial Vehicle operation uses a lower BAC standard than non‑commercial driving. The rule is that operating a CMV with a BAC of 0.04% or higher is not allowed. Among the given ranges, the one that starts at 0.04% best reflects that prohibition—the boundary is at 0.04%. The other ranges either cap before that limit or sit entirely above it, which would misstate the actual rule. Remember, the non‑commercial limit is higher (typically 0.08%), which is why CMV standards are stricter.
