Vehicles that are low-slung, such as car carriers and moving vans, are particularly at risk of getting stuck on railroad-highway crossings due to their design. These vehicles often have a lower clearance and can bottom out or become wedged in the tracks, especially if the crossing is not level or if the approach has a steep grade. This poses a significant safety hazard, as it can block incoming trains and create a dangerous situation for both the vehicle occupants and rail operations.

In contrast, while heavy trucks and passenger vehicles may face challenges at crossings, they typically do not have the same low clearance issues. Heavy trucks are generally designed for road use and are built with higher ground clearance, reducing the likelihood of getting caught on the tracks. Passenger vehicles, while they can also experience difficulties, are less likely to be low enough to become stuck compared to the specific risk presented by low-slung vehicles. Therefore, the focus on low-slung units highlights the unique considerations for safe passage over railroad crossings.
