At what Blood Alcohol Concentration (BAC) will you be placed out-of-service for 24 hours?

The correct answer indicates that any detectable amount of alcohol in your system can lead to being placed out-of-service for 24 hours. This policy is especially relevant for commercial drivers, as they are held to stricter standards due to the responsibility they carry when operating large vehicles. Unlike standard DUI regulations, which may have higher BAC thresholds, commercial drivers face regulations that recognize that even small amounts of alcohol can impair driving ability. Safety is paramount in this context, as impairments can rapidly escalate in a professional driving setting. Hence, the approach is precautionary, emphasizing that no trace of alcohol should be present to ensure maximum safety on the road.
