Final answer:
The third violation of a railroad-highway grade crossing regulation within a three-year period will lead to the loss of a CDL for a minimum of 90 days.
Step-by-step explanation:
The third violation of a railroad-highway grade crossing regulation within a three-year period will lead to the loss of a Commercial Driver's License (CDL) for a minimum of 90 days. This regulation is set by the Federal Motor Carrier Safety Administration (FMCSA) in the United States to ensure the safety of drivers and passengers at railway crossings.
Each violation is considered a serious offense and can result in severe penalties. In addition to the CDL suspension, the driver may also face fines, mandatory safety training, and increased insurance rates. It is crucial for CDL holders to be aware of and abide by railroad-highway grade crossing regulations to maintain their license and ensure safety on the roads
