How far must drivers of placarded vehicles stop from the nearest railroad rail?

Drivers of placarded vehicles are required to stop between 15 to 50 feet from the nearest railroad rail due to safety regulations concerning hazardous materials. This stopping distance is implemented to ensure that drivers can assess the railroad crossing and take necessary precautions before proceeding. Stopping within this distance allows for adequate visibility of approaching trains and provides a safety buffer that helps to prevent potential accidents involving vehicles transporting hazardous materials. The range of 15 to 50 feet is designated based on the need for drivers to gauge traffic conditions and the ability of a train to stop if necessary. Adhering to this regulation is critical in minimizing risks at railroad crossings, particularly for vehicles carrying hazardous substances that may pose additional dangers if involved in a collision.
