Low slung units are most likely to get caught on raised crossings because these vehicles have a lower clearance compared to others. Raised crossings, such as those found over railways or pedestrian walkways, can present a significant risk for vehicles that do not have sufficient height to clear the elevation. This is particularly true for vehicles that are designed to be lower to the ground, including certain types of trailers or specialized configurations that prioritize aerodynamics or load stability. In contrast, trucks with double trailers or articulated buses typically have a higher clearance, making them less susceptible to getting caught on such obstacles. Although it is technically possible for any vehicle to get caught under certain conditions, vehicles like low slung units are inherently at a greater risk due to their design and height limitations.
