Which trailers are at risk of getting stuck on raised crossings?

High Slung Units only
Single-axle vehicles with short trailers
Single-axle Tractor with a short trailer
Low Slung Units and Single-axle Tractor with a long trailer

The correct answer is: Low Slung Units and Single-axle Tractor with a long trailer

Raised crossings can present a challenge for low slung units and single-axle tractors with long trailers due to their lower clearance. These types of vehicles are at risk of getting stuck when navigating over raised surfaces due to the potential for the trailer to bottom out or become lodged on the crossing. It is important for drivers of such units to approach raised crossings with caution to avoid getting stuck or causing damage to the vehicle. Other options (high slung units, single-axle vehicles with short trailers, and single-axle tractors with short trailers) are less likely to have issues with raised crossings compared to low slung units and single-axle tractors with long trailers.
