Which type of vehicle is likely to become stuck on a railroad-highway crossing?

Low slung units like lowboy trailers are particularly susceptible to becoming stuck on railroad-highway crossings due to their design and ground clearance. These types of trailers have a lower height which means they are closer to the ground. As a result, they can easily strike the elevation of the railroad tracks, especially if the tracks are not level with the roadway, leading to an increased risk of bottoming out or becoming lodged.

In comparison, standard passenger vehicles typically have adequate clearance to navigate railroad crossings safely, while high-profile trucks have a higher center of gravity and better clearance, making it less likely for them to get stuck. All-terrain vehicles, designed for versatility on varied terrains, are also unlikely to face the same challenges as lowboy trailers at crossings. Thus, low slung units pose a unique risk that is significant in the context of railroad crossings.
