What additional requirement is there for taxpayers or taxis at railroad crossings?

At railroad crossings, drivers of taxicabs and commercial vehicles, including those with a Tennessee F Endorsement, are required to always stop before proceeding. This regulation is in place to ensure the safety of the vehicle occupants and any pedestrians who may be in the vicinity. Stopping allows the driver to check for approaching trains, which may not always be visible, even if the crossing signals are inactive.

By requiring drivers to stop, the law helps prevent accidents that can occur when vehicles attempt to cross the tracks without confirming that a train is not approaching. The other options suggest varying degrees of caution that do not meet the necessary safety standards established for these types of vehicles. The explicit requirement to stop is critical in minimizing risk and enhancing overall safety at these potentially hazardous intersections.
