Which groups may have stricter BAC limits in some jurisdictions?

Which groups may have stricter BAC limits in some jurisdictions?

• A. Commercial drivers or under-21 drivers.
• B. All drivers equally.
• C. Motorcycle riders only.
• D. Truck drivers only.

Answer: (A)

Some drivers are treated as higher risk and face stricter BAC rules to protect other road users. Commercial drivers operate heavy vehicles and may transport passengers or large cargo, so many jurisdictions require a lower BAC limit (often near zero) to minimize impairment on the job. Drivers under 21 are also subject to stricter rules because even small amounts of alcohol can markedly affect judgment and reaction times in new, younger drivers. Because of these safety considerations, the group that includes commercial drivers or under-21 drivers is the one most likely to have stricter limits. The other options imply everyone has the same limit or focus on narrower groups that aren’t consistently the ones with stricter rules.
