Quick Summary

A rail-highway grade crossing is where roads and railroad tracks intersect at the same level. These crossings present significant safety challenges because trains are heavy and travel at high speeds, making collisions with vehicles extremely dangerous.12

Drivers often misjudge a train's speed and distance due to its large size and perpendicular movement across their field of vision. This perceptual issue highlights the importance of warning drivers about crossing locations and approaching trains.2

Traffic control devices at these crossings include warning signs, flashing lights, and automated gates. While simple signs are the most basic form of control, flashing lights and gates offer more robust protection but are more expensive to install and maintain due to the necessary train detection and communication systems.2
