A sump buster is a low concrete slab or steel structure intended to stop passing of cars and other two tracked vehicles with less than a certain ground clearance and width between tracks. The vehicle will either be stopped by some low hanging part of the car hitting the block or by damaging the sump (oil pan) of the vehicle.
Ambulances, fire trucks, garbage trucks and other public service vehicles are often large enough to pass without problem.
Sometimes accompanied with signage that further restricts who can legally pass.
How to map
As always, do not place the barrier at a junction, but at a node on the branching way where the barrier actually is.
