What is the legal blood alcohol concentration (BAC) limit for commercial drivers?

• A. 0.04%
• B. 0.08%
• C. 0.10%
• D. 0.03%

Answer: (A)

The legal blood alcohol concentration (BAC) limit for commercial drivers is set at 0.04%. This standard is established to ensure the safety of all road users since commercial drivers operate larger, heavier vehicles that can cause significant damage and injury in the event of an accident. A lower BAC limit reflects the responsibility that commercial drivers have and the potential risks associated with impaired driving. At 0.04%, the law aims to minimize the risks and to promote safer driving practices among those who are driving vehicles designed for transporting goods or passengers. This threshold is specifically applicable to drivers holding a commercial driver's license (CDL) and is stricter than the general limit for non-commercial drivers, which typically is 0.08%.
