Final answer:
A commercial driver can lose their CDL for 1 year if they are found to have a BAC of 0.04% or higher while operating a commercial vehicle.
Step-by-step explanation:
In the context of commercial driving and Commercial Driver's Licenses (CDLs), there are strict regulations regarding blood alcohol concentration (BAC) levels.
For a commercial driver operating a commercial vehicle, federal regulations stipulate that a BAC of 0.04% or higher can result in disqualification from driving a commercial vehicle.
When a commercial driver is found to have a BAC at or above this limit, they can lose their CDL for up to 1 year.
It is critical for CDL holders to adhere to these regulations to ensure safety on the roads and to protect their livelihood.
Blood Alcohol Concentration (BAC) refers to the percent of alcohol (ethyl alcohol or ethanol) in a person's blood stream. A BAC of . 10% means that an individual's blood supply contains one part alcohol for every 1000 parts blood.
