What is the maximum blood alcohol concentration (BAC) allowed for a bus operator while on duty?

The maximum blood alcohol concentration (BAC) allowed for a bus operator while on duty is 0.04%. This limit is set to ensure the safety of both the operator and the passengers, as even small amounts of alcohol can impair judgment, reaction times, and overall driving ability. The 0.04% threshold is particularly significant for commercial vehicle operators, as they are held to stricter standards compared to private drivers, who may have a higher legal limit of 0.08%. By maintaining a lower BAC limit, regulatory agencies aim to promote safer driving conditions and reduce the risk of accidents caused by impaired driving.
