Must a driver stop at a highway-rail grade crossing when transporting certain hazardous materials?

When transporting certain hazardous materials, a driver is indeed required to stop at a highway-rail grade crossing. This requirement is a crucial safety measure aimed at preventing accidents and ensuring the safe transport of potentially dangerous substances. The regulations are in place because trains cannot stop as quickly as vehicles, and hazardous materials may pose additional risks if spilled or released during a collision.

Stopping at these crossings allows drivers to be vigilant about oncoming trains, providing an opportunity to observe both directions and ensure that it is safe to proceed. This practice minimizes the risk of severe accidents that could result from failing to stop, especially since the consequences of colliding with a train while transporting hazardous materials can be catastrophic, not only for the driver but also for the surrounding environment and community.
