What is the legal BAC limit for commercial drivers in many jurisdictions?

The legal BAC limit for commercial drivers in many jurisdictions is 0.04% BAC. This stricter limit reflects the higher standards of responsibility expected from those operating commercial vehicles due to their size, weight, and potential danger to public safety. Commercial drivers are subject to more stringent regulations to ensure that they are not impaired while performing their duties, which could involve transporting passengers or hazardous materials. By maintaining a lower legal BAC limit for these drivers, jurisdictions aim to reduce the risk of accidents and enhance road safety.
