Under the Federal Motor Carrier Safety Regulations, you are prohibited from driving if you have consumed any alcoholic beverage within how many hours of your start time?

The Federal Motor Carrier Safety Regulations state that a driver is prohibited from operating a commercial motor vehicle if they have consumed any alcoholic beverage within four hours before starting their duty. This regulation is designed to ensure safety on the roads by preventing drivers from being impaired by alcohol consumption immediately before driving. The four-hour time frame allows for sufficient time to pass before a driver begins their shift, reducing the risk of accidents caused by alcohol impairment. Adhering to this regulation is crucial for maintaining safety standards in the trucking industry and protecting both the driver and the public.
